A shower head is a single outlet. A shower station is a complete assembly, usually an overhead shower and a handheld shower on a rail, joined by a diverter that sends water to one or the other. That is the whole difference, and it has one consequence that matters more than any other: a shower head can often be changed in an afternoon, while a shower station changes what has to happen behind the wall. Which means the two decisions belong at completely different points in a bathroom project.
This guide sets out what each one actually is, what changes in the wall when you move from one to the other, how water pressure affects the choice, and what the water efficiency rules require of each. If you are planning a bathroom, read the section on what changes behind the wall before you settle on anything.
What is a shower head?
A shower head is the outlet the water comes out of, and nothing more. It arrives in three broad forms.
- Wall-mounted fixed head. Fixed to an arm projecting from the wall. The most common arrangement in Australian bathrooms and the simplest to service. Many are adjustable in angle, and some offer more than one spray pattern.
- Ceiling-mounted or rain head. Fed from an arm dropping out of the ceiling, or from a long arm off the wall. Water falls vertically rather than being directed at you. The look is the appeal, and the pipework has to run through the ceiling, which is a decision made at the rough-in stage.
- Handheld shower on a rail. A head on a flexible hose that sits in a bracket on a vertical rail, so it can be lifted off and used in the hand, and the bracket height adjusted. Often called a rail shower or a slide shower. This is the most practical single outlet for a household with children, pets or anyone who needs to sit while showering.
Each of these is one outlet. Water arrives at it from the shower mixer, and there is nothing to divert.
What is a shower station?
A shower station, also sold as a shower system, combination shower or shower column, brings more than one outlet together into a single assembly. The typical arrangement is an overhead shower and a handheld shower on a rail, with a diverter that directs water to one or the other, all supplied as a matched unit.
The two elements are what make it useful. The overhead gives you the fixed shower experience. The handheld gives you the practical one, for rinsing the shower down, washing a child or a dog, or showering seated. Rather than choosing between them, you get both from one set of controls.
Configurations vary. Some shower stations include the mixer as part of the visible column, so the whole assembly is exposed on the wall. Others are designed to run off a separate wall-mounted mixer, with the diverter built into the column. A third arrangement runs everything from a concealed in-wall mixer with a separate diverter, so only the outlets and the control plates are visible. The three are not interchangeable, and which one suits you depends almost entirely on what is already in the wall.
Side by side
| Shower head | Shower station | |
| What it is | A single outlet | An assembly of two or more outlets with a diverter |
| Typical outlets | One, fixed or handheld | Overhead plus handheld, sometimes with body jets |
| Controls needed | A shower mixer | A shower mixer plus a diverter |
| Behind the wall | One outlet position | Outlet positions for each element and provision for the diverter |
| Changing it later | Often a straightforward swap where it screws to an existing outlet | Usually licensed plumbing work, and often wall work |
| Best moment to decide | Any time | Before the wall is lined and tiled |
What changes behind the wall
This is the section that saves people money, and it is why the two products are not really alternatives so much as decisions at different stages.
Swapping a shower head
Where a new head screws onto the existing outlet and nothing else moves, this is usually a straightforward change. Replacing a shower head is generally treated as a minor job a householder can do, unlike work on the mixer, the wall outlet or the pipework, which is licensed plumbing work. If you are unsure which side of that line your job sits on, ask a licensed plumber before you start.
One thing not to do is remove the flow controller. Showers and taps that were tested and registered with a flow controller have to be supplied with it fitted. Removing it makes the product no longer compliant with its WaterMark certification and breaches plumbing regulations, quite apart from the water it wastes.
Fitting a shower station
A shower station needs its outlets and its diverter served correctly, and where those land is set by the specific product. If you are moving from a single head to a station, that generally means new outlet positions, which means opening the wall, which means the waterproofing membrane and the tiling in that area are disturbed.
Waterproofing is the part to take seriously. Shower areas are wet areas, waterproofing failures are among the most expensive residential building defects to put right, and this work is licensed. It is not a DIY task and it is not one to patch. If a shower station is going in after the bathroom is finished, the cost is rarely the station itself. It is the wall, the membrane and the tiling.
The straightforward conclusion is that if there is any chance you want a shower station, decide it before the wall is lined. At rough-in stage the difference between provision for one outlet and provision for two is minor. After tiling it is a bathroom job.
The middle path
If your bathroom is already finished and you want both an overhead and a handheld, a shower station that runs off the existing single outlet with an integrated diverter column is worth asking about. Not every product does this and it depends on your existing set-out, so take a photo of your current shower wall and the mixer arrangement when you come in, and we can tell you whether anything in the range will work with what you have.
Water pressure, and why rain heads disappoint some people
Overhead and rain showers rely on the water arriving with enough pressure and flow to spread across a wide face and still feel like a shower. In homes with low water pressure, a large rain head can feel like standing in light drizzle, which is not what anyone is paying for.
Two things follow. First, if your existing shower already feels weak, a wider overhead head will usually feel weaker rather than better, and a smaller face or a shower station with a handheld option is the more satisfying choice. Second, product specification sheets often state a minimum operating pressure. That figure is worth checking against your home, particularly in older homes and in some apartments.
Pressure is also a question your plumber can answer directly, and it is worth asking before you choose a large overhead rather than after it is installed.
What the water efficiency rules require
Showers are covered by the Water Efficiency Labelling and Standards scheme, the mandatory Australian Government scheme administered by the Department of Climate Change, Energy, the Environment and Water. Regulated products must be registered and labelled, and retailers must display the water efficiency details of the products they sell. The label gives a star rating and a flow rate in litres per minute. Three stars corresponds to a flow of 7.5 to 9 litres per minute for a shower, and the more stars the lower the flow.
There is a detail specific to shower stations that is worth knowing, because most people have never heard of it. Under the current WELS standard, combination shower products carry labelling and text advice showing the flow rate and star rating for both shower outlets, not one figure for the assembly. This applies to combination shower products registered for the first time after 17 June 2022, with retail and advertising media required to be updated before 22 July 2023 and product packaging before 1 January 2024. So when you are comparing shower stations, you should be able to see two ratings, one for the overhead and one for the handheld. If a product is only showing you one, ask for the other.
Two further points. Regulated plumbing products must be WaterMark certified before a licensed plumber is permitted to install them, which applies to shower stations as much as to any other plumbing product. And in New South Wales rental properties, water efficiency requirements in force from 23 March 2025 include a maximum flow rate of 9 litres per minute for shower heads, which matters if you are fitting out a property you intend to rent out.
Which one suits your bathroom?
A small ensuite
A single wall-mounted head or a rail shower usually serves better than a station. A shower column takes visual space in a small enclosure, and in a tight shower the handheld on a rail already gives you most of the flexibility a station would.
A family bathroom
This is where a shower station earns its keep. The handheld is used constantly, for children, for rinsing the enclosure down, and for anything that needs directed water. Being able to switch between overhead and handheld without changing the fitting is the practical case for the whole product category.
An over-bath shower
A handheld on a rail is close to essential, because filling and rinsing the bath is a daily task. A station with both outlets works well here provided the overhead is positioned to clear the bath edge, which is a set-out question for your plumber.
A shower used by someone seated or with limited mobility
A handheld on an adjustable rail is the important element, and the rail height and bracket range matter more than the overhead does. If a shower seat is part of the design, the position of the rail and the reach of the hose need to suit the seated position rather than being set at a standard height. Raise this early, because clearances and grab rail fixing both need to be planned into the wall rather than added afterwards.
A main bathroom being renovated to sell
A shower station shows well and reads as a considered fitout. Just make sure the finish matches the rest of the tapware, because a mismatched shower column is more noticeable than a mismatched anything else in a bathroom.
What to check before you buy
- Your existing set-out. Photograph the shower wall, the mixer and the outlet, and measure the height of the existing outlet from the finished floor.
- Whether the wall is being opened. If it is not, that rules out most changes to outlet positions.
- The minimum operating pressure on the specification sheet, checked against your home.
- The WELS star rating and flow rate, and for a combination shower, the rating for both outlets.
- WaterMark certification, which your plumber needs before installing.
- The finish, checked against the rest of your tapware. Shower stations are large and a mismatch shows.
- The rail length and bracket range if a handheld is included and anyone in the household will use it seated.
Understanding Shower Head vs Shower Station
Frequently asked questions
A shower head is a single outlet that water comes out of. A shower station is a complete assembly combining two or more outlets, usually an overhead shower and a handheld shower on a rail, with a diverter that sends water to one or the other. The practical difference is that a shower head can often be swapped where it screws onto an existing outlet, while a shower station generally requires work behind the wall.
Where the new head simply screws onto the existing outlet and nothing else changes, replacing a shower head is generally treated as a minor job a householder can do. Work involving the mixer, the wall outlet or pipework is licensed plumbing work. Do not remove the flow controller from a shower or tap, because products tested and registered with a flow controller must be supplied with it fitted, and removing it breaches plumbing regulations.
It depends on your existing set-out. Some shower stations run off a single existing outlet with an integrated diverter column and can be fitted without opening the wall. Most require new outlet positions, which means opening the wall and disturbing the waterproofing membrane and tiling. Waterproofing is licensed work and one of the most expensive residential defects to repair, so this is not a job to improvise. Take a photo of your current shower wall to your supplier or plumber before ordering.
Not while you are showering, because a diverter sends water to one outlet at a time rather than running both. Products with body jets or with outlets designed to run simultaneously are a different matter. Check the WELS label, and for a combination shower check the rating for both outlets, since the current standard requires the flow rate and star rating to be shown for each.
Usually not. A wide overhead face spreads the available flow across a large area, so where pressure is already low the result feels weaker rather than better. Check the minimum operating pressure on the product specification sheet, and ask your plumber about the pressure at your home. A smaller face or a handheld option is generally more satisfying in a low pressure home.
Three stars corresponds to a flow of 7.5 to 9 litres per minute, and more stars means less water. For rental properties in New South Wales, water efficiency requirements in force from 23 March 2025 include a maximum flow rate of 9 litres per minute for shower heads. Minimum requirements for new housing and renovations are set under state plumbing regulations, so confirm the requirement for your address with your plumber or certifier.
See the difference in person
Shower stations are difficult to judge from a product photograph, because the thing that matters is scale. How large the overhead actually is, how the column sits on a wall, and where the rail bracket falls relative to your own height are all questions answered in about ten seconds standing in front of one.
Our Smithfield showroom is open seven days, with shower stations, tapware, basins and toilets displayed alongside the tiles that go with them. Bring a photo of your existing shower wall and your set-out measurements and we will tell you what will work with what you have. Book an appointment for a design consultation, or send us your details and we will put together a quote for the bathware and the tiling together.
