8 Features Included In This Product Explained

Family Safe

Family Safe

This feature corresponds with the Thermostatic mechanism and automatic safety stops, preventing running water from getting either too hot or too cold.

Luminance Chrome

Luminance Chrome

It is a hard-wearing chrome plating which is salt-tested and scratch-proof for durable, long-lasting use.

WRAS Approved Product

WRAS Approved Product

WRAS Approval means that the particular water fitting or product complies with or meets the requirements specified by the Water Supply (Water Fittings) Regulations or Scottish Byelaws. Such compliance is based on certain tests that prove that the product or fitting does not cause waste, misuse, contamination or undue consumption of the public water supply system in the UK.



One outlet in a shower system means that hot and cold water flows from a single opening.



Drenching in Bristan showers means these showers soak you thoroughly, giving you the most indulgent showering experience.

Sequential Control In Showers

Sequential Control In Showers

Sequential Control lets you turn the shower on and off and regulate the temperature by turning the same knob. The built-in integral check valves and strainers make it easy to use. The first movement of the knob turns the shower to the cold position, and any subsequent anti-clockwise movement increases the temperature to a set maximum.

Thermostatic Control

Thermostatic Control

Thermostatic shower control works behind the scenes to achieve or maintain water temperature output from a showerhead. With the built-in safety feature, the shower provides a consistent water temperature.

Low Water Pressure

Low Water Pressure

Water systems operating at a pressure between 0.1 and 0.4 bar are considered low pressure. Products usually come labelled if they are suitable to use under such pressure.

From : CIRENCESTER Overall Rating: Date: July 6, 2022 Expected more from this brand
We replaced our shower fitting with a Bristan as we expected it to be of good quality. Upon fitting it, the water cycled between hot and hot and never got very warm, making the showering experience very poor. After months of answering more and more questions, and often many of the same, an Engineer came to review the installation. They adjusted the temperature setting. Whilst this has dramatically improved, we still get bouts of cold water whilst showering. I will not use it again.

PETER Asked :

Can the inlet feed pipes come from above as opposed to from the rear?

Answered By QS Team Answered by the QS Technical Team

You can rotate the elbows between 136-158mm, so as long as you are within this, you can position the pipes to go up or down the wall, and the pipes can be exposed.
