How to Calculate How Many Tiles You Need (With Formula)

How to calculate how many tiles you need formula and guide — Iconic Tiles Sydney tile calculator

Ordering too few tiles is one of the most expensive mistakes in a renovation — particularly if the tile is discontinued or comes from a batch with a different shade number. Ordering significantly too many wastes money. Getting the calculation right before you place the order saves both.

This guide gives you the formula, the worked examples for different room types, and the wastage rates to apply for different laying patterns. For a room with complex shapes, multiple surfaces, or unusual features, book a design consultation at Iconic Tiles — we’ll help you quantify your order accurately.

The Core Formula

The base calculation for any tile order follows this sequence:

  1. Calculate the total area to be tiled (in square metres)
  2. Add a wastage percentage appropriate to the laying pattern and room complexity
  3. Divide by the tile coverage per box to get the number of boxes required
  4. Round up to the nearest full box
StepFormulaExample
Area (m²)Length (m) × Width (m)3.5m × 2.2m = 7.7m²
Add wastageArea × (1 + Wastage %)7.7 × 1.10 = 8.47m² (10% added)
Tiles per m²1 ÷ (Tile Length m × Tile Width m)1 ÷ (0.6 × 0.6) = 2.78 tiles/m²
Total tiles neededArea with wastage × Tiles per m²8.47 × 2.78 = 23.5 → 24 tiles
Boxes neededTotal tiles ÷ Tiles per box (round up)24 ÷ 6 = 4 boxes (if 6 per box)

Note: most tile product listings specify coverage per box in m² — use this directly rather than calculating individual tile count if available.

 

Step 1: Calculate the Total Area

For a simple rectangular room, this is straightforward:

Area = Length × Width

For example: a bathroom floor 3.5m long and 2.2m wide = 7.7m²

For a rectangular wall: measure the height from floor to the top of the tiled area × the wall width. Deduct any windows or fixtures from the total, but be conservative with deductions — it’s better to overorder slightly than to underorder.

Rooms that aren’t simple rectangles

For L-shaped rooms, rooms with alcoves, or rooms with unusual angles, break the space into rectangular sections and calculate each separately, then add:

  • Section A (main bathroom floor): 3.0m × 2.0m = 6.0m²
  • Section B (toilet alcove): 1.0m × 1.2m = 1.2m²
  • Total: 7.2m²

For shower recesses and niches, measure them separately — if they use a different tile or a mosaic insert, they need their own calculation.

 

💡  Measure twice: Measure your room dimensions in at least two places per wall — older Sydney homes in particular often have walls that aren’t perfectly parallel. Use the longest dimension for each wall measurement to avoid underordering.

Step 2: Wastage Percentage — This Is Where Most Mistakes Happen

The standard industry recommendation is to add 10% to your tile order as a wastage allowance. This covers cuts, breakages during transport and installation, and future repair needs. However, the appropriate wastage percentage varies by the laying pattern chosen:

Laying PatternRecommended WastageWhy
Straight lay (grid pattern)10%Minimal cuts — most efficient use of material
Offset / brick pattern10–12%Offset cuts add modest additional waste
Diagonal (45° angle)15–20%Diagonal cuts produce significantly more waste at edges
Herringbone15–20%Complex pattern requires many cuts — high waste rate
Complex or irregular room shape+5–10% extraMore cuts at multiple angles — apply additional buffer

For mosaic tiles (sheets), the calculation is similar but use the sheet as your unit. Mosaic sheets typically have a specified coverage per sheet (e.g. 0.09m² per sheet) — divide your area by the sheet coverage, add 10% wastage, and round up.

 

Step 3: Wall Tile Calculations — Account for Fixtures

Bathroom wall tiles require measuring each wall section separately. The general approach:

  1. Measure the full wall area (height × width) for each wall to be tiled
  2. Deduct fixtures: doorways (deduct the opening), windows (deduct the glass area, not the full frame), large fixed mirrors if tiling behind them
  3. Don’t deduct smaller fixtures (towel rails, toilet roll holders, showerheads) — these are too small to meaningfully reduce tile area and the tiles around them need to be cut anyway
  4. Add all wall areas together and apply 10% wastage

 

📌  Shade lot matching: If you are ordering tiles in multiple deliveries or need to reorder, always specify the original shade lot number. Tiles from different production batches can have subtle colour differences invisible on individual tiles but visible side-by-side in a finished room. Check Iconic Tiles delivery information at iconictiles.com.au/delivery-info/ for order and reorder guidance.

Worked Example: A Complete Bathroom

Here’s a full worked example for a typical Sydney ensuite:

SurfaceDimensionsAreaAfter 10% Wastage
Floor2.4m × 1.8m4.32m²4.75m²
Shower floor0.9m × 0.9m (mosaic)0.81m²0.89m²
Wall 1 (main)2.4m × 2.4m (2.4m high)5.76m²6.34m²
Wall 2 (shower)0.9m × 2.4m (three sides = 5.4m²)5.4m²5.94m²
Wall 3 (vanity)1.2m × 0.6m (splashback only)0.72m²0.79m²
Total—17.01m²18.71m²

This bathroom would require approximately 18.71m² of tile — likely rounded to 19–20m² depending on box coverage sizes available for the chosen tile.

 

How to Convert m² to Boxes

Every tile product listing specifies either the number of tiles per box or the coverage in m² per box. Use m² per box coverage directly:

Boxes needed = Total m² (with wastage) ÷ m² per box   →   ALWAYS round UP to the nearest whole box

 

Example: 18.71m² ÷ 1.44m² per box = 12.99 → 13 boxes ordered

 

💡  Order a spare box: For large renovation projects, order one extra box beyond the calculated requirement and store it. If a tile needs replacing in five years, having a tile from the same shade lot available is invaluable — and the cost of one extra box is trivial compared to the cost of a visible patch repair with a slightly different tile.

Frequently Asked Questions

Underordering is a common and frustrating problem. If the tile is still in stock at Iconic Tiles, a second order is straightforward — but check delivery timing to ensure your tiler isn’t delayed. If the tile is discontinued or the production batch has changed, you may not be able to find an exact match. Always order with adequate wastage built in and save any leftover tiles for future repairs.

Calculate your room area in metres (m²) for clarity — most tile product listings specify coverage in m² per box. If working with tile dimensions in millimetres (e.g. 600×600mm), convert to metres first (0.6m × 0.6m = 0.36m² per tile) before calculating.

For practical purposes, the standard tile quantity formula (area ÷ tile size) produces accurate results without separately accounting for grout joints — the small amount of area occupied by grout is already effectively absorbed into the 10% wastage calculation. For precision ordering on very large areas, ask the team at Iconic Tiles to confirm the calculation. See the FAQ page for additional ordering guidance.

2026 Bathroom Tile Trends Every Sydney Homeowner Should Know

2026 bathroom tile trends every Sydney homeowner should know — Iconic Tiles Sydney trend guide
Sydney bathrooms in 2026 are increasingly defined by a single design direction: the pursuit of calm. After years of bold statement walls and highly contrasted palettes, the defining bathroom aesthetic in Sydney’s renovation market this year is quieter, more textural, and more material-focused. The tile is doing less visual noise and more genuine work. This guide covers the tile and design trends that are most prominent in Sydney bathrooms being renovated right now. See the Iconic Tiles bathroom range for current products that align with these directions.

Trend 1: Natural Stone Looks — Without the Maintenance

The look of natural stone — particularly marble, travertine, and limestone — has been a consistent presence in aspirational bathroom design for a decade. What’s changed in 2026 is how that look is being achieved. Advances in porcelain printing technology have produced large format porcelain floor tiles and wall tiles that are genuinely difficult to distinguish from the real thing at normal viewing distances. The practical appeal for Sydney homeowners is real: natural stone is beautiful but demands significant maintenance — sealing, careful cleaning product selection, and vigilance around moisture and staining. Quality stone-look porcelain delivers the aesthetic at a fraction of the maintenance commitment.
  • Beige, warm ivory, and soft grey travertine looks dominate — replacing the cooler grey marbles that characterised bathroom design five years ago
  • Book-matched large format tiles (two tiles mirrored to create a continuous pattern) are increasingly used on feature shower walls
  • Travertine natural stone is also available for homeowners who specifically want the real material — with the understanding of its maintenance requirements
 
💡Stone tile tip: When choosing a stone-look porcelain, view the full tile box rather than a single sample — variation between tiles in the box tells you how realistic the randomisation pattern is. A truly good stone-look tile has meaningful variation between pieces, as natural stone does.

Trend 2: Textured Wall Tiles and Tactile Finishes

The most significant emerging trend in 2026 bathroom design is a turn toward texture on walls. In bathrooms that previously would have been uniformly smooth, textured tiles — 3D relief surfaces, handmade-look undulations, ribbed profiles, and layered geometric patterns — are appearing on feature walls, shower backs, and bath surrounds. The effect is to add depth and warmth to a bathroom without colour or pattern complexity. A textured white or off-white tile on a shower wall creates visual interest in changing light conditions — which in a bathroom that often relies on artificial lighting, is a meaningful design tool.
  • Ribbed / fluted tiles — vertical or horizontal ridges on wall tiles, particularly in elongated formats; best used on a single feature surface rather than all walls
  • Handmade-look ceramic wall tiles — slightly irregular surfaces, subtle variation in glaze, irregular edges; adds character without complexity
  • 3D geometric tiles — used sparingly as feature accents rather than room-wide; add architectural interest in niches, splashbacks, and bath surrounds
Iconic Tiles’ mosaic and feature tile range includes textured and 3D options suited to feature wall applications.

Trend 3: Warm Neutrals Over Cool Greys

The cool grey bathroom — which dominated Sydney renovations from roughly 2015 to 2022 — is fading from the frontline of design. What’s replacing it is a warmer neutral palette: creamy whites, warm beige, terracotta accents, clay tones, and soft sand shades. This shift is partly aesthetic and partly reactive. Years of grey bathrooms have produced a collective fatigue with the palette; homeowners renovating now are more likely to choose a warm white or a soft taupe over the standard cool grey.
  • Warm white and cream large format tiles paired with warm-toned fixtures (brushed brass, matte black, aged bronze) are the defining combination of 2026
  • Terracotta and clay accent tiles — used on feature walls, niches, and splashbacks rather than throughout, adding warmth without overwhelming the space
  • Greige (grey-beige hybrid) — tiles that read differently in different lights, warm in natural light and slightly cooler in artificial — the most versatile neutral in the 2026 palette

Trend 4: The Spa-Minimal Aesthetic — Less Grout, More Continuity

Sydney bathrooms in 2026 increasingly aspire to a spa-like minimalism — surfaces that feel continuous, calm, and uninterrupted. The practical expression of this is large format tiles with colour-matched grout that makes grout lines near-invisible, creating the impression of a single continuous surface. The technical requirements for this look are exacting — very flat substrates, consistent adhesive coverage, and grout colour carefully selected to match or complement the tile body. The result, when executed well, is a bathroom that feels genuinely luxurious without any single statement element.
  • Large format floor tiles (600×600mm+) with matching grout — the foundation of the look
  • Continuous floor-to-wall tile treatments — using the same tile (or closely matched tile) from floor through shower wall eliminates the visual disruption of a transition
  • Rectified tiles — tiles with machine-cut edges allowing minimal grout joints (as small as 1.5mm) are essential for the spa-minimal look

Trend 5: The Return of the Feature Niche and Alcove

After years of flush, undifferentiated tile surfaces, the shower niche is back as a design moment. Rather than a functional recess, niches in 2026 bathrooms are treated as small galleries — lined with mosaic tiles, contrasting tiles, or natural stone that create a deliberate visual accent within the otherwise calm surface.
  • Mosaic-lined niches in a contrasting colour or material to the shower wall surround
  • Arched niches rather than square — the arch form is appearing in Australian bathrooms as part of a broader softened geometry trend
  • Full-height alcove features — a recessed section of wall tiled in a contrasting material as a feature element, rather than a single niche

Trend 6: Sustainability-Conscious Choices

Sydney homeowners in 2026 are asking more questions about where tiles come from, how they’re made, and what happens to them. This doesn’t always change the decision, but it’s increasingly part of the conversation:
  • Recycled content tiles — tiles incorporating recycled glass or ceramic content are available and increasingly requested
  • Locally manufactured options — Australian-made tiles carry shorter supply chains and reduced shipping impact
  • Clearance and discontinued lines — Iconic Tiles’ clearance range offers quality tiles at reduced cost, which also diverts stock from waste
 
💡  Renovation longevity: The most sustainable tile choice is one you’ll keep for 20+ years. Trend-chasing at the cost of timelessness is the opposite of sustainable. If you’re drawn to a bold trend tile, consider using it as an accent rather than throughout — your whole-room commitment to a trend is the highest-risk choice.

Frequently Asked Questions

Cool grey has softened from its peak dominance, but it hasn’t disappeared — particularly in contemporary and industrial-influenced bathroom designs. What’s changed is that it’s no longer the default first choice. Warm neutrals are now more prominent. Grey tiles in warm-toned variations (warm grey, greige) remain very relevant; very cold, blue-toned greys are less current.

Natural material aesthetics (stone looks, travertine, warm neutrals) have shown consistent staying power across multiple renovation cycles — they’re rooted in timeless design principles rather than fashion cycles. Textured tiles and the spa-minimal aesthetic similarly have longevity. Feature trends like arched niches may date more quickly. The best approach for a renovation is to treat the foundational tile as timeless and use accents to express current trend interest.

Porcelain vs Ceramic Tiles: Which Is Right for You?

Porcelain vs ceramic tiles comparison guide – Iconic Tiles Sydney which is right for you
It’s one of the most common questions in any tile showroom: what’s the actual difference between porcelain and ceramic? Both come in similar formats, similar aesthetics, and often similar price ranges. Both are sold for floors and walls. And both are described as ‘quality tiles’ by every supplier that stocks them. But the differences matter — and they matter differently depending on where the tile is going. This guide gives you the technical truth without the jargon, so you can make the right choice for each application in your home. Browse the Iconic Tiles range and bathroom tile collection once you know what you’re looking for.

What’s the Technical Difference?

Both porcelain and ceramic tiles are made from clay fired in a kiln — but that’s where the similarity ends. The key differences come from the clay composition and firing temperature:

Ceramic tiles

Standard ceramic tiles are made from red or white clay body, typically fired at lower temperatures (around 900–1150°C). They have a higher water absorption rate — typically above 0.5% — which means they absorb more moisture through the tile body. Ceramic tiles are generally softer than porcelain and easier to cut, which makes them more workable for DIY installation and complex cuts.

Porcelain tiles

Porcelain tiles are made from a refined white clay (kaolin) mixed with other minerals, fired at higher temperatures (1200–1400°C). This higher-temperature firing produces a much denser, harder tile with water absorption below 0.5% — typically below 0.1% for quality porcelain. The density of porcelain means it’s significantly harder and more resistant to wear, but also harder to cut and typically heavier.  
💡Technical test: Water absorption rate is the defining technical threshold between porcelain and ceramic in Australian standards. Below 0.5% water absorption = porcelain. Above 0.5% = ceramic. This matters most in wet areas and outdoor applications.

The Key Practical Differences

Property

 Porcelain

Ceramic
Water absorption Very low (<0.5%, typically <0.1%) Higher (>0.5%)
Density and hardness High — more durable, more wear-resistant Lower — more workable but less durable
Outdoor suitability Suitable (low water absorption prevents freeze-thaw damage) Less suitable for frost-prone outdoor areas
Cutting difficulty Harder to cut — requires diamond blade Easier to cut — more DIY-friendly
Through-body colour Often through-body (colour throughout tile) Usually surface glaze only
Weight Heavier — may require substrate assessment Lighter
Typical cost Generally higher Generally lower
Maintenance Very low — dense surface resists staining Moderate — glaze important for stain resistance
Note: specific product properties vary between manufacturers and product lines. Always check individual tile specifications.  

Where Each Is the Right Choice

Porcelain is the better choice for:

  • Bathroom floors and shower areas — the low water absorption is valuable in permanently wet applications
  • High-traffic floors — kitchens, hallways, entryways where durability and wear resistance matter
  • Outdoor paving — outdoor tiles in Sydney’s climate experience rain and moisture; porcelain’s low absorption prevents problems over time
  • Timber-look and stone-look tiles — most realistic timber and stone imitation tiles are porcelain, using advanced digital printing on a dense base
  • Underfloor heating systems — porcelain’s thermal properties and stability make it more compatible with heated floor systems

Ceramic is a good choice for:

  • Bathroom and kitchen walls — walls don’t need the water resistance of porcelain (moisture resistance comes from the glaze, not tile body) and the cost saving is real
  • Low-traffic interior floors — indoor tile applications in bedrooms, studies, and light-use areas where heavy wear isn’t a concern
  • DIY projects — ceramic’s easier workability makes it more forgiving for homeowners installing themselves
  • Feature walls and decorative applications — where the aesthetic is primary and technical performance requirements are lower
 
📌  Outdoor ceramic caution: In Sydney’s coastal suburbs, outdoor ceramic tiles can absorb moisture and, in cooler months, experience surface degradation over time. For outdoor applications, porcelain is strongly preferred — its low water absorption is the key outdoor durability factor.

The Through-Body Advantage

One of porcelain’s most practical advantages is often overlooked: through-body colour. Many quality porcelain tiles are coloured and textured through the full depth of the tile body, not just on the surface glaze. This means that chips or edge wear reveal the same colour — a chipped edge on a through-body porcelain tile is far less visible than a chip in a surface-glazed ceramic that reveals a different-coloured clay body beneath. This is particularly relevant for floor tiles in high-use areas, and for tiles used in the natural stones category where through-body texture is part of the aesthetic.

What About the Aesthetics?

From a design perspective, modern porcelain printing technology has narrowed the aesthetic gap between porcelain and ceramic significantly. High-quality porcelain can realistically imitate marble, timber, concrete, and natural stone in ways that are indistinguishable to the eye in a finished room. The remaining aesthetic difference is that ceramic tiles tend to have a wider range of handmade-look, artisan-style, and decorative finishes — particularly in smaller format wall tiles — because the softer clay body is easier to texture, mould, and glaze in complex ways. For feature wall tiles and artisan-look bathroom walls, ceramic often offers more design variety.

Frequently Asked Questions

Not always — ‘better’ depends entirely on the application. Porcelain is better for wet areas, outdoor use, and high-traffic floors. Ceramic is a perfectly appropriate and cost-effective choice for bathroom walls, interior feature walls, and low-traffic floors where its lower water absorption isn’t a limitation. Paying for porcelain performance where ceramic would serve equally well isn’t necessary.

A ceramic tile with an appropriate glaze can be used on shower walls — the wall surface stays above the waterline and the graze provides surface protection. However, for shower floors and wet area floors, porcelain is recommended due to its lower water absorption rate. If you’re using ceramic wall tiles in a shower, ensure the waterproofing membrane behind the tiles is thoroughly applied and professional-grade. See our bathroom floor tile range for porcelain options with appropriate wet area ratings.

Check the product specification sheet — water absorption rate is listed for most quality tiles. Below 0.5% is porcelain; above is ceramic. If in doubt, ask in-store — the team at Iconic Tiles can confirm the tile classification for any product in our range. See the FAQ page for additional specification guidance.

How to Choose the Right Tile Size for Your Bathroom

How to choose the right tile size for your bathroom - Iconic Tiles Sydney tile size guide

Tile size is one of the decisions that gets least attention and has most impact. Walk into a bathroom where the tile size is wrong — too small for a large floor, too large for a compact shower recess — and something feels off immediately, even if you can’t name exactly what it is. Get it right and the tiles disappear into the design, the room feels proportional, and the renovation looks intentional.

This guide covers the practical principles behind choosing bathroom tile sizes — for floors, walls, showers, and feature areas. Browse the Iconic Tiles bathroom tile range to see what’s available once you know what you’re looking for.

The Core Principle: Tile Size and Grout Lines

Before anything else, understand one fundamental relationship: tile size and grout line frequency are inversely linked. Smaller tiles create more grout lines; larger tiles create fewer. This affects both the visual texture of a surface and its practical maintenance — more grout lines mean more surface to clean.

In bathrooms specifically, where moisture is constant and hygiene matters, minimising grout lines on floors and shower walls is often a practical preference as much as an aesthetic one. This is one of the strongest arguments for larger format tiles in bathrooms — not just the visual spaciousness they create, but the reduced grout maintenance that comes with them.

Bathroom Floor Tiles: What Works at Each Size

Bathroom floor tiles carry specific requirements beyond aesthetics — they need a slip rating (the P-rating system rates wet area slip resistance in Australia, with P4 or P5 recommended for wet areas), appropriate hardness, and in larger formats, a flat enough substrate to lay without lippage.

Large format floor tiles (600×600mm and above)

Large format tiles — 600×600mm, 600×1200mm, 800×800mm, and larger — have become the dominant choice in modern Australian bathrooms. Their advantages in a bathroom context are meaningful:

  • Fewer grout lines reduce moisture ingress points and simplify cleaning
  • Continuous surface creates visual flow that makes the floor feel larger
  • In smaller bathrooms, large format tiles can make the room feel more spacious — counterintuitively, a tile that’s proportionally large for the room often works better than a tile that creates a ‘busy’ grid

The practical requirement for large format tiles is a very flat substrate — larger tiles span greater distances and will rock if the floor isn’t sufficiently level. Your tiler will need to assess and prepare the substrate accordingly.

 

💡The 1/3 rule for floors: A commonly used guide is that no single tile should be cut to less than one-third of its full size at the perimeter. When planning your layout, check that your room dimensions work with your chosen tile size without creating awkward narrow cuts at the edges.

Medium format floor tiles (300×300mm to 600×600mm)

Medium format tiles are the most versatile for bathroom floors. A 300×300mm or 400×400mm tile works in most bathroom sizes and can be laid in a range of patterns — straight lay, offset, diagonal — that add visual interest without overwhelming a smaller space.

Small format and mosaic floor tiles (under 300×300mm)

Small format tiles and mosaic tiles are often used in shower recesses — both because their smaller size accommodates the gradient required for drainage more easily (the tiler has more flex points to work with), and because their texture provides natural slip resistance. A shower recess tiled in mosaic tiles with the floor in large format creates a deliberate visual differentiation between zones that reads well in most bathroom designs.

Bathroom Wall Tiles: Different Rules Apply

Bathroom wall tiles carry different considerations from floor tiles. Slip rating doesn’t apply to walls, which opens up a much wider range of surface textures and formats. Wall tiles also bear the majority of the bathroom’s visual load — they’re the surface you see most, and they set the design tone of the space.

Tall format wall tiles (600×1200mm and above)

Tall, slim format tiles — particularly the increasingly popular 600×1200mm and 800×2400mm formats — create striking vertical lines that lift the visual height of a bathroom. They’re particularly effective in bathrooms with ceiling heights of 2.7m or above. Laid with matching grout or near-invisible grout, the effect can make a bathroom feel genuinely spa-like.

The practical consideration: taller format tiles require very flat walls. Stud frame walls sometimes need additional preparation for large format tiles to sit without wobble.

Standard format wall tiles (200×400mm to 300×600mm)

These are the workhorse wall tiles of most Australian bathroom renovations. A 300×600mm wall tile laid in a horizontal stack (all grout lines aligned) creates a clean, contemporary look. Laid in an offset pattern (brick pattern), the same tile creates more visual movement. The same tile size reads very differently depending on the laying pattern chosen.

Mosaic and feature tiles for walls

Mosaic and feature tiles on walls are typically used as accent elements rather than full-room treatments. A feature tile on the shower back wall, a mosaic niche, or a contrasting tile to the vanity wall creates visual hierarchy within the bathroom — drawing the eye to key elements and adding depth to what might otherwise be a flat, uniform surface.

Common Sizing Mistakes and How to Avoid Them

MistakeWhy It HappensHow to Avoid
Too many tile sizes in one roomWanting to ‘use everything’Limit to two tile formats maximum per space; let one dominate
Cuts that are too narrow at edgesNot planning the layout around room dimensionsMap the tile layout before ordering; adjust start point to balance cuts
Wrong grout width for tile sizeUsing standard grout width regardless of formatAsk your tiler — large format tiles typically suit 1.5–3mm grout; mosaics 2–3mm
Large format on uneven substrateSkipping substrate assessment to save time/costInvest in substrate preparation — lippage in large format tiles is permanent

Frequently Asked Questions

Often yes — but it depends on the specific tile and how it’s laid. A large format tile in a continuous, unbroken colour with minimal grout in a matched colour can create the illusion of a larger floor area. The key is minimal visual interruption. A highly patterned or strongly coloured large format tile in a small bathroom can have the opposite effect.

Australian standards recommend a minimum P4 wet area slip rating for bathroom floors and P5 for shower bases. The higher the P-rating, the more grip the tile surface provides when wet. Iconic Tiles’ bathroom floor range includes options with appropriate P-ratings — check individual product specifications or ask in-store. See the FAQ page for more tile specification information.

Yes — using the same tile on floor and walls (or a closely coordinated tile from the same range) creates a seamless, spa-like effect. The practical requirement is that the floor tile must have an appropriate slip rating for wet areas, which wall tiles don’t need to have. If you want to use the same tile body, verify it carries the required P-rating for the floor application.
