Browse Forums Bathrooms and Laundry Re: New bathroom, toilet leak 5Jul 25, 2016 8:22 pm Wet areas is a tricky one. Lots of factors involved with it, down to the tradesmen constructing the floor, walls, sheetings and floor system to applying waterproof membranes to the people regulating/approving it. AS3740 states for general bathroom floor areas a min 1:100 fall is required to a waste outside the shower. Your issue seems to be with the waterproofing membrane along with the water stop angle at the door, bond breaker silicon to floor and wall junction, perimeter flashing, and reinforced fabric etc. Even with the silicon to the floor and wall junction the reinforced fabric, membrane over the top and a water stop or even the aluminium tile trim at the door with a coating of the membrane on top, you shouldn't have got that much water through to the bedroom. These waterproofing/wet area issues are concerning and things are improving with tradesmen becoming more competent and consumers having access to information helps improve these things but there are still lots of problems. Having said all of that, it could be that the builder/tiler has performed all that is required and the leak was excessive and caused your problem, the tough thing is trying to prove it either way.

Yeah, that's the min fall HYG, the common sense fall should be closer to 20mm. Ever seen a couple of kids in a bath ? The floors are usually awash and the only way to stop water escaping from the bathroom is a decent fall to the waste. I agree with everything else you say though. Stewie Re: New bathroom, toilet leak 7Jul 26, 2016 9:22 am Yeah I agree, I was just trying to quote the requirements set by the AS rather than my own opinion on it just so the Op knows the min, set out by that book. Going above the min requirement in these wet area applications is something I encourage. Better more than not enough. Re: New bathroom, toilet leak 8Aug 03, 2016 10:59 am I was told that was the minimum fall for the shower but there isn't a standard for the main bathroom fall??? We have a building inspector coming out tomorrow so will hopefully have an answer then. Re: New bathroom, toilet leak 9Aug 04, 2016 9:04 am Is there a floor waste in the bathroom apart from the one in the shower ? If there is ( and there should be ) , then there needs to be fall to it. BCA rules for wet areas. Stewie Re: New bathroom, toilet leak 10Aug 09, 2016 2:33 pm We had the building inspection done and the building inspector measured the fall of all the bathroom floors and they're fine. He said the same as the builder-that there is water coming from somewhere it shouldn't and it is still seeping out. Both the builder and the inspector are stumped. So we are returning the toilet that was leaking and hoping that will fix the problem. Hi all, I am hoping someone has some ideas as to what is causing my bathroom leak. The leaking appears to mainly happen when we turn the sink basins on.
