Fitting stone shower tray on floor (plumber says no cement required?)

glenimp617 · 31 May 2019 at 10:20

I'm having a new en-suite fitted and the plumber is saying he will install the shower tray straight on the floor. The manually states it requires a sand/cement mix but he says that's rubbish.

The floor is having to be taken up so the waste pipes can run under it.

any ideas?

I'd be siding with the manufacturers instructions.

When did my shower we put the shower tray on bed of cement ensured it was nice and stable and didn't move or flex

I've been doing a lot of research into bathrooms recently; and although I am not installing a shower tray, the information I've stumbled across has always had it installed on a bed of cement.

as have I

thing is, he's not cheap....we'll I don't think he is. £750 just for the labour?

if that is what you want then tell him to cement it down.

either get him to do as you wish, or get him to sign something saying if it breaks its his responsibility when/if it goes wrong. Or get a plumber who is willing to follow instructions?

He'll use 15 tubs of silicone instead

glenimp617 · 31 May 2019 at 11:46

I'm going to use a different plumber I think

when the customer starts telling a plumber how to do plumbing, something aint right lol

How else will you level it if not bedding into a a cementius base?

ANDARIAL · 31 May 2019 at 16:34

Yeah needs bedding in something
Tile adhesive or `possibly` a lot of mastic is do able

He probably doesn’t know how to mix the cement

What material is the shower tray?

The OP's title might give you a clue :rolleyes:

Ask him to bed it in as per instructions or get rid of him

The Artfull Bodger · 1 Jun 2019 at 22:16

Not being funny, but if he plans just silliconing it to the floor, it's fine as long as he levels it. I would personally use rapid set S2 tile adhesive being stone resin and not the 1 finger lift trays people love buying online (silicone or sticks like being the only option there afaic).

I meant what kind of stone is it... :rolleyes:

I've got a granite shower tray, and I was going to give him done advice if his shower tray was similarly weighty as we've had no end of problems with it.

Could be building a timber base, to raise it so would sit on that, so saves digging and plus the trap is bigger than waste pipe.
