Advice on this wet room tray

[budest]

Hi guys,

Downstairs wet room with a 1300x820 wet room tray installed. The floor I lifted was a wet room vinyl floor but because of the design of the vinyl (curved at edges where it came up the wall) I decided to lift it. But now I am unsure what to do next!

Given that there is a bit of a bounce to the tray I am not comfortable tiling over it. So what are my options? Someone suggested to me to rip it out and fit a show tray. Is that possible? I will post this in the tiling room too.

Thanks

What you have there looks like a shower former - it is designed to take vinyl/tiles etc. If the vinyl wet room floor was curved up the wall then it would have been hermetically fitted and sealed by a pro installer.

Why it's flexing is anyone's guess - could be it isn't supported the best below or just naturally flexing. You could always use the same former and tile over it yes but it will always be a different level as the tile is thicker.

Could you cut it/lever it out and put in a proper tray, don't see why not but the fun will be getting the former out and seeing what the cleared space offers you. Couldn't really say until the former was removed.

Thanks for the response mate.

I will set time aside tomorrow and see if I can remove it and get some pictures.

Apologies for the delay in getting back to you mate, but I have now removed the tray and can show you what was below it. In my humble opinion I think a shower tray could work here. Agree? Any advice?

PS: "Why it's flexing is anyone's guess - could be it isn't supported the best below or just naturally flexing."

I found out that the reason it was flexing was because, as you suggested, it wasn't supported the best below.

Yes a tray will work on that for sure.

Depending on what you are looking for though, I would possibly consider raising a tray slightly on a plinth with an 18mm top on it, that will allow it to handle a hi flow trap easily. Of course, you could always re-instate the former and set it down properly.

Thanks again mate.

The issue with the old tray seems to be that it wasn't suited to the recess cut out of the floor and therefore had to be supported by make-shift packers. This is why I was experiencing the flex obviously.

Some measurements of what I have to work with...

Oh yes - that was never going to work long term on a fibreglass former - never in a million.

That being said if there weren't any crack or the like in the former then a good flexible tile adhesive would sort that.

If you've got 140mm then that should be plenty for a hi flow shower trap. Just ensure there is a least a min of 19mm/m fall on the waste run.

Question: If I get a shower tray with a depth of 37mm and given there is already a 20mm recess cut out of the floor for the last tray, that leaves 17mm of the tray exposed above floor level. If a floor tile is 10mm thick, is it plausible a tiler could lay them on a bed of 7mm adhesive to keep tiles flush with the tray?

The dimensions of the area are:

800mm wide
1295mm long
20mm deep

I was therefore looking at 1200 shower trays with the view to filling in the last 100mm or so with a weak cement mixture.

Yes - I am sure a tiler could achieve that - just need a good tiler and be very clear with what you want , to ensure he keeps it all nice and level with that height of adhesive. He would probably work out from the tray to maintain the level, either that or they could use a self levelling compound to raise the surrounding level.

I'll keep you updated as I am going to tackle this project myself.
