Rated 5 out of 5 by from Works fine on Trinity shower After a lot of back and forth with Bristan trying to work out whether this would work in my 2003 Bristan Trinity shower, the results were inconclusive. The original part had 3 seals, this had 4. I originally changed just the seals, but only cold water came out, so the thermostatic part of it must have been broken. Bristan eventually admitted that the original cartridge was slightly different but the only one the made these days was CART 06732COMPL. Seeing as this Screwfix part was to all intents and purposes the same and also substantially cheaper than CART 06732COMPL, I thought I would try this. I was initially put off by another reviewer stating that this cartridge wouldn't work with the Trinity shower, but I have tried it and it fits and works just fine - flow and temperature control work perfectly. Don't know what issue he had, but his review, however well intentioned, is misleading. Anyway, thought I'd better write this down in case it helps anyone else with the same dilema.

Rated 5 out of 5 by from be aware I found this item when searching for a bristan cartridge, it was under the correct category and listed it as item number "cart06732compl" when seeing the item on screen it looked identical to my needs. However the item number (not noticed at the time of ordering ) changed to 9446j. on arrival I fitted same, all went well until final assembly ie the flow and temperature control. they do not fit the bristan trinity shower .

Rated 5 out of 5 by from Best Value and price out there Bought this for my Bristan Omega shower, the cartridge is in fact the Bristan Cart06732, fitted great and no issues, I would have liked to see a small tube of silicone grease with it.

Rated 5 out of 5 by from Bristan Shower Fitted first time - quicker and cheaper than from the manufacturer. Next-day C&C really works.

I currently have a Bristan CART 06732COMPL cartridge. Is this the same model - it looks the same!

Asked by: DMQuestion
The Bristan CART 06732COMPL is the same cartridge as Screwfix cartridge code 9446J: Bristan Thermostatic Mixer Shower Cartridge.

Would this fit 1900 bistan mixer valve

Asked by: Markmcl
This fits my 2004 model Bristan 1901 perfectly and works like a dream. Make sure to use a little smear of silicone grease on all the seals, and ensure that the back end valve section is closed with no hole visible before installation. There were alignment marks on cartridge, I installed it with them at 5 o'clock position. One word of warning...dont turn any other part of it ,before fitting, or its very fiddly to correct.

Is this suitable for Bristan SX0711 and SX0612 shower mixers?

Asked by: Franzleschner
SX0711 and SX0612 are etching codes that do not clearly identify the shower mixers you refer to. We can tell they are from July 2011 and June 2016 approx but not the models. Please advise the models of shower in question.
