Ok, now that I have a lounge full of bathroom bits in boxes, I'm starting to mobilise my bathroom project!

I want to understand how best to fit the shower tray, as there seem to be a variety of different views. Having done a lot of reading, my approach is as below, and any views would be appreciated (thanks in advance macca!).

I'm installing a 900mm quadrant shower tray (stone resin) upstairs on a wooden floorboard surface.

1) Sort all pipework under floorboards
2) Board over the floor with 12mm tileboard to get a flat even surface
3) Check shower tray area is now level and flat - bed with sand if required
4) Offer up shower tray to wall, fix to wall with adhesive along the vertical faces
5) Seal all edges with silicone

Thoughts? I know some people choose to bed on a dry mix of cement and sand, but I'm not sure the value this adds? Other people have suggested bedding it into a tile adhesive mix to fix the tray, but again, I can't get a consistent view from everyone.

Cheers for any comments!
 
The only advice I would have is to make sure the tray is stable and doesn't keep breaking the mastic seal, you can tank the wall and down to the floor I'd look at reinforcement with mesh I keep forgetting what it's called doh
 
ive fitted probably around 50 shower trays and they were all years ago and they're still going strong today, no movement..

were as the shower tray fitted in my own house was fitted by a complete idiot who as a plumber gets paid more than me to do a bad job..

which ever way you do it, the things in your list will see you good though id do it slightly differently..
 
What would you do differently Mickie? I'm doing as much research as I can but I'm still a novice!

My current strategy is going to be (slightly changed from OP):

- Overboard the floorboards with 6mm cement based tile board
- Make a shower tray plinth from 18mm WBP ply
- Grub around under the plinth getting the waste connections in place
- Create bed of 5:1 sand/cement mix with PVA
- Bed tray
- Fit shower boards a day later on top of the tray
 
Bloody nightmare this! I got a tray mate easy plumb kit and a tray mate stone resin tray. Having mixed the bedding cement as instructed, bedded the tray on, I left it for 24hours with the intention of levelling and fixing the base today and then fitting my shower panels. What I discovered though was that although the cement had bonded to the ply, it hadn't bonded to the tray at all! The tray is therefore free floating so I can't see how the hell the cement will help with bedding the tray. I've got a fitter coming out tomorrow to look at it, I'm just really narked that after 4 days of work, having replumbed the room, refloored, etc etc, I've got stung by something that should have been an easy job!

Rant over, thanks guys!

Hi, I'm not able to send you a PM for some reason.

I've got 2 x TM25 Elementary shower trays and want to avoid issues after installation. Could you advise what you did at the end? Did it work out?
