Thermostatic bath shower mixers - standard fittings?

I will search, but limited energy for the next few days.



We have a Triton bath shower mixer, which is showing signs of the thermostat failing. What I would like to do is take the mixer part off without touching the bath fittings (long story) and just bolt a new one on.



They all look very similar in pictures, but I was wondering if the spacing between the hot and cold connections was standard.

This looks very similar. The 150 mm between the big nuts which fasten the body to the incoming water connection is also ringing bells.



If they are all standard fittings, can anyone recommend a cheap but reliable (!) replacement? Under £100 would be good.



We are planning to have the shower bath replaced by a walk in shower fairly soon, so don't want to go for the top of the range.



Thanks

Bar mixer shower valves have a centre to centre of 150mm. Bath mixers have a C to C of 180mm. Of course, if it is really old, or an obscure make, it could be different. Screwfix have some pretty decent budget taps in.

We have two Triton mixers, one on the wall and one on the bath. I've just measured up, and both mixers have 150 mm centres.

I think the mixer was designed for a wall or bath fitting so had the same centres.

The issue I had with the original installation is that the builders used a

180 mm template to cut the holes in the bath, and had to adapt the incoming fittings to give 150 mm.

Thanks for the useful information.

Cheers
