Shower tray fitting

[JackieVivas]

Hi Guys,

Fitting a shower tray in this new bathroom, and everywhere seems to say that i shuild cement this in place. Its 25kg, its not a flimsy plastic one. Do i really need to cement it or can i get away with other adhesives, and if so what do u recommed?
Secondly is it recommended to cut the tray into the wall? ive got glass doors to fit so i suppose this would alter the actual depth of the tray if it was in the wall by any amount?


Thanks Guys..... Stressed ha, DIY seems like a good idea at the start eh

Presumably a stone resin tray?

They do need supporting across the base otherwise they might crack. Firstly, if the manufacturers recommend something, it might be wise to go with that for warranty purposes.

I've used mortar, and works well and is easy enough - make up a weak mix,spread it pretty thinly, as level as you can. then plonk the tray on top. Easier if you have someone else to help lower it straight down. Tap it down gently to get it level.

But I also know people that have used silicone sealant, and tile cement successfully.

Belt and braces is to use flexible tile adhesive and then the back of the tray make sure to scratch it up with 80 grit paper ,this will form a perfect key

Sounds more appealing than cement.. Can anyone advise weather I should 'cut' the tray into the wall? This will throw my doors out I think cos there 900 glass panels for a 900x 900 tray

Definetly not. Put it up against the wall ,if you are worried about any leaks then you need to use a tanking Kit

Thanks,
No boards to tank, all brick wall behind tiles

Cheers again

Brick wall which will have been plastered either using Bonding Hardwall or Cement render

All of which need to be tanked to be water proof!

Ah I thought it was just boards.... So do I tank the plaster after it's dried, or the actual brick wall

Not wanting to hijack but if the resin trays require even support across the bottom then how do the riser kits work?
