How to choose the right wall mixer

Wall mixers are ordered in two parts: a rough-in body installed behind the wall before tiling, and a trim kit or plate fitted afterwards to match your chosen finish. If you are renovating rather than building new, check whether your existing rough-in is still serviceable and compatible with the brand and plate size you want, since rough-in bodies are not universal across manufacturers.

Decide whether the mixer needs to control a single outlet (typically a shower head or arm) or two outlets via a diverter, such as a bath spout and hand shower. Plate size and shape also matter for a clean finish against your tiling pattern; round plates suit softer, contemporary layouts while square plates read as more architectural. Order the rough-in early in a build so it is set before waterproofing and tiling begin.

Frequently asked questions

What is a wall mixer used for?
A wall mixer controls hot and cold water for a shower or bath from a single lever mounted on the wall. It is typically paired with a separate shower arm, hand shower or bath spout, rather than including the outlet itself.
Do I need a rough-in body for a wall mixer?
Yes. Most wall mixers are sold as a two-part system: a rough-in (or body) that is plumbed into the wall during construction or renovation, and a trim kit or plate that is fitted once tiling is finished. Confirm you are ordering both parts, or that your existing rough-in matches the trim kit you choose.
What is the difference between a wall mixer and a wall mixer with diverter?
A standard wall mixer controls one outlet, usually a shower. A wall mixer with diverter lets you switch flow between two outlets, such as a bath spout and a hand shower, from the same control.
Can wall mixers be installed in a tiled shower with no exposed pipework?
Yes, that is their main advantage. Because the body is concealed behind the wall and only the plate and handle are visible, wall mixers suit fully tiled, minimalist shower and bath surrounds.
