My most recent DIY project has been to convert my en-suite into a wetroom. Been at it for months and now at the finishing stage. Turned on the shower for the 1st time and I have pooling in the centre of the floor.

I have obviously misjudged how large a shower tray footprint I require.

I have come to terms with the fact I’ll need to pull up the tiles and start again to include a fall.

My query is can I just build my fall or should I replace the shower tray?

Have you set the tray into the floor and tiled onto it?

As it's pooling in the centre of the floor, this suggests it's outside of the tray, and may well just be down to the tiles not being level when you laid them. Put a level across the tiles, and check for any dips first.

Oh ok.

You really need to have lined your floor with backer board of some kind before tanking and tiling.

The problem is that outside of the shower try I have laid the tiles flat so water out side of the tray does not find it’s way the drain and pools in the middle. I need to redo the tiling to include a fall across the whole room.
I’m thinking that I’ll build the fall in with a build up of thin set mortar. 10-15mm over 1m should solve the problem.
How would you suggest doing this? Use spacer to set the height and fill in the rest?
Thanks

I thought that backer boards were only required to raise the floor to match the height of the shower tray? Or in the case where very thin chip board or ply wood was present (to increase strength).
Is it really a concern? The chip board was in good condition very flat and unbroken also the membrane 100% water proof covered the whole area.
I would hate to have done that wrong as I specifically choose the 22mm shower tray to match the chip board.
Appreciate your thoughts.

You can’t/shouldn’t fix direct to chipboard flooring, but because you need to take it up anyway at least you can start again. Everything up then fix down hardiebacker boards or tile insulation boards fixed down with flexi adhesive and screws/washers. All chipboard floor covered then tank everything again. This will build up floor higher than tray and give you a basis to create a run to drain.

I agree with callatiler. Best to use the backer boards and tanking to build.up your fall than spacers and adhesive.

[Distant sound of gunshot]......

Wet rooms are a steep learning curve, the first one you do is never ending deathslog but gets easier. I hate doing them though and talk people out of it if I can.

I know you wanted a wetroom but they can be a pain to live with if small as everything gets wet. It'll be easier and cheaper to replace the glass panel with a cubicle onto the tiles..... you'll then have a floor level walk in style shower.....surely that's better than ripping it up.

I had thought of that and found a nice frameless door one on VP. But as you say I wanted a wetrooom and feel like I’ll be dissapointed / feel like I failed every time I look at it. I could be convinced tho...

You'll be convinced every time you dry yourself with a wet towel or wipe your *** with soggy loo roll and your fingers break through . I've got a tilet shower with wetroom styke tray and a semi frameless cubicle.....much better and the cubicle is a feature.
