The Methven Wai Concealed Mixer Valve, Single Outlet is a thermostatic concealed shower valve, supplied complete with a slimline concealing plate. Separate flow and temperature controls let you set the volume and the temperature independently, with a 38°C hot stop and override facility. Front-access filters can be serviced without disconnecting the valve from the water supply, and protective covers are included for use during installation.
A single outlet is suitable for a drencher, handset or bath filler. The valve is suitable for low-pressure systems, with a working pressure range of 0.1–5.0 bar, and is TMV2 and WRAS approved. It is available in Chrome and Matte Black, and coordinates with the Methven Wai tap range.

Care tips
- Regular cleaning is recommended to avoid stubborn build-ups of dirt and limescale. For regular cleaning, use a soft cloth and mild soap or detergent.
- Never spray cleaning agents directly onto the product, as the spray can get inside and cause damage where the concentrated cleaner cannot be rinsed out. Always spray the cloth then wipe the product, or use a cloth that is damp with a water and detergent solution.
- Never use metal or abrasive scouring pads, as these will scratch and damage the finish. Never use cleaners that contain a scouring additive, such as crème cleaners that contain silica.
- Do not use aggressive or highly acidic cleaners, including products containing sodium hypochlorite (chlorine bleach), formic acid, hydrochloric acid, hydrogen peroxide or ammonia. Never mix cleaning agents. The use of harsh or abrasive cleaners will void the product warranty.
- After cleaning, remove any residue left by the cleaning agent by rinsing thoroughly with clean water and wipe dry using a dry soft cloth. Do not leave cleaning products in contact any longer than necessary.
For the official warranty terms, see the Methven standard warranty.
