Browse Forums Bathrooms and Laundry 1 Oct 01, 2023 5:50 pm Hi, I'm renovating a couple of bathrooms both with shower recesses, roughly 900 by 900mm. Floor wastes are in the centre of the shower recesses and there is an angle at the shower entrance that will protrude above the finished 600x300 tiles. I've had the waterproofing done by a good professional, and yesterday my tiler laid the screed on the floor. The screed looks to be almost level, so I got a levelling laser onto it and can see about 5mm fall from the walls to the wastes, both in the room and in the shower recesses. So the fall in the showers is almost 1:100 and the fall in the rooms is more like 1:400. I've asked the tiler if the fall is enough, and he said "that's how we do it for big tiles", meaning that you can't have too much fall with larger tiles or it looks bad. I understand the building code requires a minimum fall of 1 in 80. I'm concerned that the shower recesses may not drain effectively with such little fall. Should I be concerned? Or is that really "How we do it with big tiles"? Thanks for any advice.

If using large format tiles than different drainage solutions and design needs to be completed to acheive the standard falls. Re: Fall in Shower Floor 5Oct 02, 2023 5:44 pm Thank you Splashers. Tomorrow I might check if I can get a few packs of 300x300 in the same tile finish. It may be good to use these could in the shower recesses. I'm not so concerned about the main floor as this does not get routinely wet. From what I’ve seen, balconies usually need a minimum fall of 1:100 for drainage under NCC 2022. It’s a bit different from the 1:80 to 1:50 for internal wet areas. I… 2 1563 I've got a challenge here.
