Who makes this model of thermostatic bath shower mixer?

was pointed to

This looks close..

My guess is it's a standard mechanism fronted by some hugely overpriced designer ditz, and what you need to to is remove the whole thing, blank off the pipes, and start visiting showrooms. Chances are you will get complete replacement guts and be able to re-use the fancy bits.

They'd be THL in Hornsey High Street - who inded may well have supplied it originally.

The shower is not the problem it's the whole new wall that is. The unit is set into the outside wall (must have taken away half the bricks to do this) and then set for the duration with mortar, tile adhesive and tiles.

I'll print off the picture and tout it around. TA.

Alas one of the fancy handles has sheared off. Not by me (phew!).

You are almost certainly right. I'm half expecting the guts to come out and be standard kit. More often as not they are held in left handed so I'm ready for that one.

Thank you so much. It really is the same model right down to the position of the chrome domes, the etched numbers for the temperature knob etc.etc.

That was lucky then.

Good luck. Bastard things, shower mixers.
