Mixer tap for basin query

BobbyJoe · Sep 22, 2020

Hi everyone,

At present I have a single one hole mixer tap in the bathroom basin but would like to know is it possible to get a thermostatic mixer tap for a basin? I have a thermostatic shower which is great and the basin tap isn't great and it would be great to install a tap with a temperature I can control just like my shower.

Any advice or suggestions would be greatly appreciated thank you.

1. Yes, you can get them. Search for "thermostatic basin mixer tap".
2. Make sure you get one which suits your system pressure.
2a. If you have a tank fed system, the basin tap pressure of a first floor bathroom with tanks in the loft above will be about 0.2 bar, so low pressure. I doubt you will find a thermostatic basin mixer for this type of system.
2b. If you have a combi boiler, an unvented hot water cylinder or a pumped supply, the pressure is likely to be 1.0 bar or higher, so high pressure.

Would this kind of tap be any good for high pressure water? and do thermostatic basin mixer taps usually cost a bit more than normal tap? Would there be any alternatives to a thermostatic basin mixer tap?
