Browse Forums Bathrooms and Laundry 1 Aug 29, 2013 10:56 am Hi all, very new here, and to forums in general, so please take it easy i am soon too renovate my bathroom, 1st floor, concrete slab, about 2m x 3m. I am going to tile the shower and floor with 300x600 tiles so i intend to use a linear drain just off center in the shower, as this is where the existing drain is and a long linear drain parallel to the wall on the floor. there is a large hob (900mm x 900mm) between the shower and the only other floor drain as below ; --------------------------------- I I I Door way I x drain I I I I I ------------------- I Hob I I ------------------- I x floor drain so seen as it is above the ground floor i intend to waterproof the entire bathroom floor and up 150mm around the edges, and slope the area between the door and shower toward the shower drain. Is this acceptable? and will i still need a water stop at the shower perimeter? if so, im a little unsure as to what the bca considers an enclosed shower, i do intend on having a shower screen but i am uncertain what type as yet, but the code states an enclosed hobless showers must have a water stop that extends 5mm above the finished floor, this would prevent water draining to the shower, but un-enclosed hobless the water stop should be flush with the top of the tiles?? does this mean im better off just not getting a shower screen and water proofing + tilling 1500 from shower head along the walls? any advice would be greatly appreciated, cheers PS, i am unable to find any codes relating to linear drain constuction, i.e is it a requirement for the base of the drain to be stamped so that it is sloped to the outlet? i have seen quite a few cheaper drains with flat bases, are these accpetable for bathroom floors? i wouldnt use one in the shower just the floor. Re: Water stops 3Aug 30, 2013 8:08 am Porxee, when considering waterproofing imagine the room before it is tiled, because this is principally all the protection you get. The majority of water is repelled by shower screens and tiles, but there is always some water travelling behind the tiles. Therefore I like your approach of sloping the floor back toward the shower and tiling the walls adjacent to the shower. I would also definetly still fit a shower screen, just think of the whole bathroom as part of a shower enclosure. Most linear drains from hardware stores are completly inadequate as they have no lip to project across the floor. The waterproofing and tiles should go over these lip edges, otherwise you have a problem. Custom made shower drains dont have this problem but they cost approx $300. @builderforlife Building inspector and passionate about construction When you need an expert to take a look. Re: Water stops 4Aug 30, 2013 11:14 am thank you for the reply builderforlife, so in thinking of the whole bathroom as part of the shower would that make 1 water stop across the bathroom doorway adequate and within regulations? any other considerations? with the drain, i was going to waterproof over the screed, drain channel and into a puddle flange then fit the linear drain over this and tile up to it. this would still allow the majority of the water to go down the linear drain and anything getting through the tiles/grout would still easily find its way to waste? is there something im overlooking? my biggest concern with the cheaper linear drains is their lack of fall to waste within themselves, therefor there would be water sitting in the corners, probably only minute amounts, but sitting stagnating none the less. i would really appreciate and tips, advice or experience as a lot seems to have changed since last time i had anything to do with bathroom renovation, mainly that fact than back then no one seemed to give two hoots about what the regulations said and you could do it however you liked. cheers Re: Water stops 5Aug 30, 2013 9:10 pm Porxee, one waterstop at doorway wil suffice. If you waterproof over screed and into p[uddle flange then you can use a hardware store linear grate. The flat bottom on a stainless steel grate should be ok, think of it like the floor tiles getting wet, they are both impervious. @builderforlife Building inspector and passionate about construction When you need an expert to take a look.
