2-way recessed single lever mixer with diverter

AISI 316L stainless steel does the structural work inside this concealed Volga shower valve, where the body sits behind the tile and only the trim is ever seen: a corrodible core would be a poor trade against decades of hidden operation. The valve is a 2-way single lever mixer with a push-button diverter that returns automatically, feeding an overhead and a handshower outlet from one control with no separate switch to remember. It connects on a G1/2” supply.

Key features

• Push-button diverter returns automatically, so it can't be left mid-way by mistake.
• Single lever gives one-handed temperature control instead of two taps to balance.
• Concealed body means only the trim plate shows in the finish you specify.
• Four finishes let the exposed trim match the rest of the Volga bathroom.

Specification and installation

The recessed body needs a chase deep enough for its 135mm and 117mm dimensions, so confirm wall thickness before first fix; the trim covers a Ø65mm cut-out over bores as small as Ø22mm and Ø36mm, giving some tolerance if the rough-in shifts slightly. Run the G1/2” and G3/4” connections to the valve before tiling, since the body is inaccessible once finished. Pairs with a Volga overhead shower or handshower set on the outlet side.
