Rainflo 348 Thermostatic Shower Mixer

Built for a guest bathroom that has to impress without a fuss, Rainflo 348 runs off standard 15 mm supply, no dedicated pump needed at normal mains pressure.

It is chrome-plated brass: solid brass under a chrome plate, which is what keeps the internal waterways from scaling shut the way plated plastic eventually does.

Internal waterways are brass or stainless throughout — anything else scales up and chokes flow within a few years of hard water. Ten years of daily use leaves a door seal or a roller tired long before the glass or the tub itself gives up.

Care

Descale the head or nozzles every few months in hard-water areas; that alone accounts for most warranty returns on fittings like this.
