[Closed] Anyone installed a shower tray?

Walls built first boarded to the floor but not with plasterboard.
Use a tile specific backer board.
Silicone the gap between the tray and wall before tiling.
Stick tray to floor with silicone / gripfill, but not too thick.
I usually use a bit of silicone when making the trap in too.

as above, tile backing board is called hardibacker, don't use silicone, use stixall or sticks like sh1t. i then paint it all with wet room tanking.

You want to make sure any water on the rim of the tray goes into it, not over the edge. Sealant of any kind [u]will[/u] leak sooner or later, in my experience, so it may be better to put the tray tight to the existing walls and then board down into the tray. Depends a bit on the shape of the tray rim, I bought one with a lip on the outside. The above approach was based on having had to replace the MDF floor after the previous shower tray (not put in by me) leaked onto it undetected...

Do not board onto the top of the tray.

Silicone will only leak if movement or not a gap to push into if tiles are tight onto tray. Several manufacturers recommend sealing the tray to the wall as I mentioned before tiling.

Hardibacker or Marmox, remember to put fixings in stud wall for door and slide bar etc.

I try to use Mira trays too as they seem pretty decent.

....or just do it the easy way by installing the tray then fitting Mermaid shower boards down onto it, which come with a sealing system and a quality sealant that contains plenty of fungicide.

Sorted.

Done that too.
Or I'll trump that. Vinyl floor wet room no tray required just wall boards. In fact did one that the walls were vinyl too!

I can't beleive people are still messing around with tiles when there are so many good, flexible and durable alternatives around nowadays.

Ask the same question on tilersforum. There'll be plenty of good advice on there.

several things here! some professionals already responded so I'll chuck my hat in too as I tile and fit bathrooms for a living.

NEVER use MDF on a floor, it swells if it gets wet so especially so in a bathroom and is not suitable to tile on if that's the intention.

build and board the walls 1st, then tank (personally i'd have used hardiebacker instead of plasterboard) Do not board down onto the tray.

fit the tray between all 3 of the boarded walls, I use flexible tile adhesive to bed the tray into on the floor, make up the trap etc with silicone as you don't want leaks if flush fit. Then silicone to between tray and all three walls.

Tile or whatever wall finish, then silicone the tiles to the tray. DO use a good quality silicone Dow Corning 785 is all I'll use.

Thanks for the replies guys.
Must admit, there seems to be a few different opinions.
Been looking on tileforum and DIYnot too - again there are several suggestions.

My inclination was to effectively slot the tray snugly into the 3 boarded walls, as per Blazin-saddles recommendation. As I said, I'm tanking 12.5mm plasterboard as opposed by buying expensive Mermaid boards or Hardibacker/Aquapanel - that SHOULD be ok if done properly shouldn't it?
I've seen a thing called Aquastrip that's a rubber seal that goes around the top of the shower tray too - anyone familiar with it/do I need one?

Blazin - what shall I do with the floor?

Thanks again - quite nervous about undertaking this bloody job now 😕
Will be starting it in the next few hours...

Blazin has it right.

You say tanking plasterboard - implies you are putting a lining over the top?

don't use the aquastrip.

Was going to use BAL WP1 - it's a paint-on sealant...apparently...
