The first bathroom in most Australian homes is a compromise. It does the job it needs to do, but it does it in less space than anyone would choose if space were unlimited. The good news is that the feeling of spaciousness in a bathroom has much more to do with design choices than with actual square footage. And the most impactful design choice of all, by a significant margin, is the tile.
At Iconic Tiles in Sydney, we see small bathrooms transformed regularly by tile selections that work with light, visual continuity, and proportion. Here are the ideas that consistently deliver the most impact.

1. Choose Large Format Tiles
This is the single most effective tile choice for a small bathroom. In a compact space, numerous small tiles create numerous grout lines, and grout lines are the visual signal that breaks up surface continuity and makes spaces read as busy and small.
Large format tiles (600x600mm, 600x1200mm, or larger) reduce the number of grout lines dramatically. The eye reads fewer lines and perceives a more expansive surface. The bathroom does not get bigger, but it reads as bigger because the visual interruptions are minimised.
The principle applies to both floor and wall tiles. A bathroom tiled from floor to ceiling in a large format tile of the same family creates a seamless visual field that maximises the apparent volume of the space.
| 💡 Match floor and wall tile families: Where floor and wall tiles share the same colour and material family (even if they are different in size or finish), the visual boundary between the floor and the wall softens. This unified surface effect is one of the most powerful ways to make a small bathroom feel like a single continuous space rather than a series of surfaces in a tight box. |
2. Go Light on Colour
White, off-white, soft grey, pale stone, and muted greige tones all work for the same reason: light colours reflect more of the available light back into the room rather than absorbing it. In a bathroom with limited natural light (common in internal bathrooms in many Sydney apartments and older homes), light-coloured wall tiles turn artificial light into a room-brightening tool.
There is a practical note here: keeping your floor tile in the same light palette, rather than going much darker on the floor than the walls, removes the contrast that visually anchors the floor and makes the room feel lower. A consistent light palette from floor to ceiling creates the maximum sense of height and openness.
This does not mean small bathrooms must be boring. A light base palette creates the perfect backdrop for a single, carefully chosen feature element: a contrasting niche tile, a patterned mosaic in the shower recess, or a statement tapware finish that stands out precisely because the surrounding tile is calm.
3. Use Vertical Tile Layouts to Increase Apparent Height
The direction your tile is laid has a measurable effect on how the space reads. In a small bathroom with standard ceiling height, laying rectangular tiles in a vertical orientation (portrait) draws the eye upward and makes the room feel taller. In a bathroom with a particularly low ceiling, this effect can be dramatic.
Common vertical layouts that work well in compact bathrooms:
- Vertical brick bond: rectangular tiles (such as 300x600mm or 200x600mm) laid vertically in a brick bond offset. Clean, contemporary, and height-extending
- Stack bond vertical: rectangular tiles laid vertically in a straight stack, with continuous vertical grout lines that emphasise height
- Herringbone or vertical herringbone: the diagonal arrangement of herringbone adds movement without the horizontal emphasis of brick bond laid on its side
For floor tiles in a small bathroom, the opposite principle applies: laying elongated floor tiles horizontally (landscape orientation, with the long axis of the tile running across the room rather than toward the entrance) makes the floor feel wider.
4. Match Your Grout Colour to the Tile
This is the simplest single change that makes the most immediate visual difference. When grout is a noticeably different colour from the tile (for example, dark grey grout with white tiles), every grout line becomes a visible line. Every visible line subdivides the surface and makes it read as smaller.
When grout matches or closely matches the tile colour, the grout lines become invisible or nearly so. The surface reads as continuous and the room reads as larger. For white tiles, a white or very pale grey grout achieves this effect. For stone-look tiles, a grout that matches the dominant stone tone works the same way.
There is a maintenance consideration to be honest about: perfectly white grout in a shower will eventually show some colour change from soap and water deposits, and will require periodic grout cleaning to maintain the crisp appearance. This does not negate the design benefit, but it is part of the informed choice.
5. Tile the Shower Recess to the Ceiling
A common approach in older bathrooms is to tile the shower walls to a fixed height (typically around 2,100mm) and leave the wall above that point painted. In a small bathroom, this paint break creates a horizontal line that cuts the perceived height of the space at exactly the wrong place.
Tiling the shower recess from floor to ceiling creates a continuous tiled column within the room that emphasises height. Combined with a frameless or semi-frameless shower screen that maximises visual transparency, this approach makes the shower feel open and the overall bathroom feel more generous.
6. Use Mosaic Tiles Strategically
Small mosaic tiles are not the best choice for covering the majority of a small bathroom’s surface area: they introduce many grout lines and can make small spaces feel busy. But used strategically in specific zones, mosaic tiles are one of the most effective ways to add personality to a small bathroom without overwhelming it.
The best use of mosaics in a small bathroom:
- A single niche tile in the shower recess (the niche itself is already a defined zone; a different tile there adds interest without adding visual noise to the main surfaces)
- The floor of the shower recess, contrasting with a larger format main floor tile, to delineate the wet zone without closing in the overall space
- A narrow horizontal border or band at a specific height on the wall, creating definition without subdividing the main wall surface
7. Consider Rectified Tiles for Tighter Grout Lines
Rectified tiles are tiles that have been cut to precise dimensions after firing, meaning their edges are more perfectly square and consistent than standard tiles. Because they are more dimensionally accurate, rectified tiles can be laid with smaller grout lines (sometimes as narrow as 1.5 to 2mm for wall tiles).
Narrower grout lines mean less visual interruption and a more seamless surface appearance. In a small bathroom where every visual interruption contributes to the impression of smallness, the difference between a 3mm and a 1.5mm grout line across a full wall of tiles is visible and worth considering.

Frequently Asked Questions
Large format tiles (600x600mm or 600x1200mm and larger) are generally the most effective choice for making a small bathroom feel bigger. They reduce the number of grout lines, create a more continuous surface, and make the room read as less busy. Smaller tiles can work in specific accent zones, such as the shower recess or a feature niche, but covering the main surfaces in small tiles typically emphasises the compactness of the space. Browse Iconic Tiles’ bathroom floor tile range to see the large format options available.
They do not need to match exactly, but using tiles from the same colour family and a similar visual character creates a continuity that makes small bathrooms feel more generous. The strongest effect comes from tiles that are so close in tone that the eye perceives the floor and wall as part of the same surface field rather than as separate planes meeting at a junction. Contrasting floor and wall tiles can work in larger bathrooms where the contrast adds layering; in a small bathroom, contrast tends to make the space feel more divided.
In most cases, yes, particularly on walls. Dark tiles absorb light rather than reflecting it, which makes a room feel more enclosed. However, dark floor tiles in a small bathroom can work if the walls are kept light: the contrast grounds the room without closing it in. A very dark, moody bathroom aesthetic can be achieved in a small space if the design is committed and the lighting is generous. For most small bathroom renovations, a light palette remains the most reliable approach to creating the impression of space.
