Tiling

Gap between wall and shower tray

Anonymous user 03/03/2024 - 3.10 PM

As part of an ongoing saga with an issue of damp in my bathroom (now into its 20th month of trying to resolve) my original shower tray has (today) been replaced with a new one by a builder, ahead of the tiler coming tomorrow. The tiler is scheduled to retile the area within the shower enclosure. However, I have a 14mm gap between one wall (which isn't square) and the tray itself. This has been filled with clear mastic. I wish I could attach an image to show you. The wall tiles are 8mm thick. I can't see how the tiles will eventually sit on the edge of the shower tray. The tile cement/adhesive would need to be troweled on "very" thickly to do that. To my unskilled eye something seems very amiss and I fear I'm only going to encounter more problems further down the line. Do I cancel the tiler now and call a halt to tomorrow's work or not? To all you professional tilers reading this... I really do need some sound advice. Thank you.

Are you a tradesperson and able to answer this question?

Any good tiler will just simply pack out and make square just a bit harder for the tiler , ask him to seal tray first with good quality silicone , Tile it then seal again in a top quality sealant like forever white etc . and up all corners . Will be fine , Been tiling almost 36 yrs and this is no big problem .

you will have at least a 4mm bed of adhesive on wall and a good tiler will also butter up tile itself , total about 6 to 8 mm plus 8 mm tile ,coupled with silicon seal to tray ,, should be fine ,tile does not need to sit on tray ,although good practice the silicon seal will do the trick

Your tiler will probably have an electric wet bench saw.This enables thin slivers of tile to be cut. First remove the present 14mm mastic ribbon. Cut strips of tile about 25 to 35 mm wide. Place & fix these 35 mm strips on the shower tray to bridge over to the wall tiles . Ideally the wall tiles should sit on top of the infill strips so your tiler MIGHT be able to trim about 15mm off the bottom of the wall tiles using an angle grinder to enable those wall tiles to master the infill strips. Fit the infill strip using waterproof adhesive on to the shower tray at a slight angle so that the water drains into the shower tray . Run a ribbon of anti fungal silicone about 6mm at the junction of wall and 35mm tile sliver and between the tile sliver and the shower tray. Ideally the shower tray should have been fitted to align with the back of the wall board so that such gaps do not occur. Additionally to use a cementitious board at the base of a bath wall and shower walls will help to reduce disintegration of a plasterboard wallboard should any part of the silicone seal fail.

Hi It is very hard to answer your main question without having a look at the actual job. from my experience, if no gap you'll need to re-seal around your shower or bath every 3 years or so , as big as the gap becomes as earlier u ll need to re seal( it's up to how much used and the quality of the silicone used...). hope this helps

Hi I'm sorry to say but the work was wrong planned, walls should be prepared before fixing the shower (to keep the angle)
