How to Remove a Grohe Thermostatic Mixer Shower

Head_The_Ball

You can probably get a decent quality new unit for well under £100.

eBay has thousands of them.

Grohe, HansGrohe and Aqualisa are all decent makes. There are probably many other good makes too.

15cms is a standard spacing between hot and cold feeds so most products on the market will be an easy swap. Your OH appears quite capable of that if he has already removed and refitted the existing unit.

You should try and choose a new unit that will cover up any holes or marks etc left by the existing unit.

Good luck.

Will the threads be the same (i.e. metric) on the new models because ours as I say is 20 yrs old at least ?

Probably but I can't be certain. Metric fittings were introduced to the UK a long time ago.

If not, adapters are probably easily available, or you could remove the old screw fittings from the pipes and fit a metric fitting.

That should be a simple enough job for anyone with basic plumbing skills.

You could remove the unit again and take it to a local plumbing merchant and ask their advice.

Just an update for all those who provided advice for which thanks !

We have now purchased a brand new Grohe Thermostatic Mixer Shower which took 5 minutes to swap over and it is working fine. Can't believe the plumber persuaded us to buy new parts for our Valiant boiler costing us with labour £400 and it turned out to be the shower. Why he couldn't have taken the unit to a plumbing depot to ask their advice or try changing what probably would have been cheaper parts to replace than our Valiant Boiler parts, I don't know.

We could probably have got the faulty parts in the old shower unit changed ourselves but decided at 20 yrs old we needed to invest in a new one ! However £500 (boiler repairs and the new shower unit £100) to get the shower replaced is a bit expensive !

However, again thanks to all for the advice, we are a little older and wiser now thanks to everyone here !
