How to Fit a Shower

The traditional mains-fed shower can be a liability. One flush of a loo or turn of a hot tap can leave you under a torrent of scalding or freezing water. Thermostatic mixer showers allow you to preset the temperature you want to shower at and then maintain that temperature — regardless of innocent, or malicious, water use elsewhere in the house.

Many thermostatic mixers can be used with pumped systems, gravity, standard mains pressure or combination boiler-fed supplies. But check with the supplier that the one you want is compatible with your water system before you buy.
