Wall Basin/Bath Mixer Set

Wall basin and bath mixer sets buying guide

A wall basin and bath mixer set puts the tap in the wall instead of on the basin or the bath. A spout and a mixer, or a spout and a pair of handles, come out of the wall at the basin or the bath, and the plumbing runs inside the wall. This page holds wall mounted basin mixers, wall basin and bath sets and wall mixers, in brushed nickel, chrome, gold, bronze, gunmetal, black, brass and white, from several brands. The guide below sets out why a wall set suits some bathrooms, what the plumber needs at rough-in, how to check the spout reach and height, and how to look after it.

What a wall mixer set is

A wall set has two parts. The body is the valve, and it sits inside the wall and connects to the pipes. The trim is what you see: the spout, the mixer handle or handles and the plates that cover the openings. Most sets include the spout and the mixer together, and a set made for a basin and a bath can serve either, with the same shape and finish. The spout is fixed or swivels, and the handle is a lever, a paddle or a pair of cross handles.

Why choose a wall set

A wall set keeps the basin deck or the vanity top clear, so there is nothing to wipe around and no base plate to catch limescale. It suits a floating vanity, a wall hung basin, a stone or a very slim vanity top and a bath without a deck. It gives a clean, architectural look, and it lets you place the tap at the height that suits the basin. The cost is planning: the plumbing is set before the wall is tiled, so the choice cannot wait until the end. If you want a tap you can still swap easily later, a hob mounted basin mixer is more forgiving.

Rough-in: what the plumber does first

The body is fixed to a solid timber noggin inside the wall frame, with its face parallel to the finished wall, and set level. The pipes are connected and tested for leaks before the wall is sheeted. Many bodies come with a plastic cover that protects them while the wall is plastered and tiled. A universal body can be installed before you choose the final trim, which is useful if the finish is still undecided, but the trim must be made to fit that body. Calculate the finished wall thickness, including the sheeting and the tile, so that the plate and the handle fit at the end, and ask the maker if your wall is unusually thick.

Spout reach, height and the basin

Check three measurements before the wall is closed: the projection of the spout from the wall, the height of the spout above the rim of the basin or the bath, and the distance between the pipe centres of the set. The water should land near the centre of the bowl, close to the waste, not on the rim, so measure from the wall to the middle of the basin and compare it with the spout projection on the product page. The spout should clear the rim with room for your hands. The pipe centres vary between sets, so read the figure for your chosen model and give it to your plumber and your tiler.

Wall set or basin mixer

A wall set has the controls in the wall, a basin mixer has them on the basin. Choose a wall set for a clean bench and a wall hung or floating look. Choose a basin mixer for the simplest fit and the easiest future swap. A basin mixer needs a tap hole in the basin or the bench, and a wall set needs none, so it also suits a basin with no tap hole. See bathroom basin taps for every basin tap type together, and three piece taps for sets with separate handles.

Wall sets for the bath

The same set works at a bath. The spout should clear the bath rim and project far enough to land the water well inside the tub, and a swivel spout turns to serve a bath beside a basin. Choose the height with your plumber before the wall is closed. If you want a spout that turns, see swivel bath spouts, and for floor mounted and deck fillers see bath fillers.

Wall sets for floating vanities and wall hung basins

A floating vanity or a wall hung basin leaves the wall as the only place for the tap, so a wall set is the natural match. Decide the basin first, because the spout has to line up with the bowl. Set the spout height so the water falls into the bowl and not onto the rim, and keep the handle far enough from the basin edge that your hand does not hit the bowl. If the vanity has a tall mirror or a shelf directly above, check the clearance for the spout and the handle. Give your tiler the exact positions so the cut-outs in the tile are accurate.

Planning around tiles and niches

The plate and the handle should sit on a flat tile, not across a grout line or an edge, so ask your tiler to centre the tile pattern on the tap position. Keep the plate away from a corner, a niche or a mirror edge, because the handle needs room to swing. A large format tile makes the placement more visible, and a mosaic hides small errors. If the wall is stone or a feature tile, confirm the cut-out size from the product sheet before the stone is cut.

Protecting the trim at installation

The trim goes on at the end, after the tiles and the paint. Fit the plate, the handle and the spout by hand where you can, and wrap a cloth around the part before gripping it with a wrench, because tools mark a finish. Keep the original packaging until the job is done, and keep the plastic cover on the body until the wall is finished. Test the mixer and the spout before the plumber leaves, and check for drips at the plate and the spout joint.

Handles and operation

A single lever mixer sets flow and temperature with one hand and suits most households. A paddle handle is flat and slim and suits a modern room. A pair of cross or lever handles gives a classic look and separate hot and cold control. Check that the handle can lift or turn fully without touching the tile, the basin or the mirror, and that the spout does not sit too close to the handle for your hand. A progressive mixer starts on cold and warms as it turns, which saves hot water on a quick rinse.

Cartridge, body and lead-free rules

We recommend a solid brass body and a ceramic disc cartridge. A ceramic disc cartridge uses two ceramic plates to control the water, resists wear and shuts off cleanly for years. The bodies on this page are brass, lead-free brass and stainless steel, including 316 grade, which suits coastal bathrooms. The National Construction Code limits lead in plumbing products that touch drinking water to 0.25 percent from 1 May 2026. Check WaterMark approval on the product page, and use a licensed plumber to fit the body and the trim.

Water use and pressure

WELS is the Australian water efficiency label, and more stars means the tap uses less water. Check the rating on the product page. Mains pressure gives you the most choice. Low pressure and gravity fed systems need a tap rated for it, and a plumber can check the pressure at your tap. Wall sets are fixed in the wall, so confirm the flow suits your pressure before the wall is closed.

Choosing a finish

Finish is the last decision, and the spout, the mixer and the plates should share it, along with the bath outlet and the shower. The finish process differs by colour: chrome and matte black are mostly electroplated, while brushed nickel, brushed gold, bronze and gunmetal are mostly PVD, which bonds the colour to the metal and resists scratching and tarnish.

• Chrome suits white tiles and classic rooms. See chrome taps.
• Matte black gives contrast against pale tiles. See black taps.
• Brushed nickel is soft and muted. See brushed nickel tapware.
• Brushed brass and gold are warm against timber and marble. See brushed brass taps and gold taps.
• Gunmetal and bronze are dark and warm. See gunmetal tapware and bronze taps.

Caring for a wall mixer set

Wipe the spout, the handle and the plates with a soft microfibre cloth and warm water, and add a little mild soap if needed. Dry them so water does not set on the surface, which matters most in hard water areas. Avoid bleach, harsh sprays and abrasive pads, which dull a finish and can strip a coating. Wipe the plate edge where it meets the tile, and check the seal now and then. If the mixer drips from the spout when it is off, a new cartridge is the usual fix.

Replacing an existing wall mixer

Look at the trim and the body behind it before you order. A new trim has to fit the body in the wall and cover the opening, so identify the body and its maker, or ask your plumber to. If the old body is worn or does not suit a new trim, the wall may need to be opened to change it. Keep the pipe centres and the spout height in mind, because a different projection or height changes where the water lands.

What comes in the box

The contents depend on the set. A wall basin and bath set comes with the spout, the mixer, the plates and an installation kit, and the in-wall body may be included or sold separately. A trim kit comes with the plate and the handle, and a body only product comes with the valve and no trim. Read the product page for the exact list before you order.

Wall sets by brand

The wall sets on this page include Nero taps, Phoenix taps, Caroma taps, Fienza taps, Modern National tapware and Clark taps. Staying with one brand and range keeps the handles, spouts and finish consistent through the room. For outlets only, see spouts, and for the shower side see shower mixers.
