Hi all

Challenge of the day. I went to fit one of this in wall shower thermostats. Turns out the wall is only 3" stud and the valve is just under 3" deep. The valve body has 2 fixing holes to attach it with.

I tried bolting 2 "L" shaped brackets to the back and the screwed these onto the studs. It works but the valve body is not secure. It wobbles back and forth and left and right. I stuck some timber to the plasterboard behind the valve which stabilised it a bit but still it is not very stable.

I guess if I can cut the Hardie backker board with a tight fit around the valve (bit challenging) and mastic the front face to the wall it would be more stable but.... All seems a lot of "Ifs and buts" and would much rather get it stable now.

Any ideas?

Thanks

Lee.
