Rated 4 out of 5 by from Good Replacement Having my shower hot water fade in and out and finding out online that it was probably the thermostat cartridge took it out and took it to Screwfix when I saw this look alike one on the site. My shower isn't Bristan. The agent let me take it out of the box to compare. looked very similar - fitted it and worked perfectly - great stuff.

Rated 5 out of 5 by from great product Great shower cartridge, just repaced it after about ten years constant use. Web site has the length wrong. It's about 94mm not 138mm. Hope they change the site details.

Rated 4 out of 5 by from It works! After struggling for years with intermittent problems with the shower, fitted this quickly and easily and problem solved. Just hope it lasts, but for the price no quibble.

Rated 4 out of 5 by from Good price but beware This is a great price for a Bristan thermostat but Bristan only gives 1 year's guarantee on spare parts. If you buy this take a screen print and try to hold Screwfix to the 5 years it shows. However they may refer you to their terms and conditions for a get out.
