Browse Forums Bathrooms and Laundry 1 Oct 22, 2022 6:29 pm Yo, I’m renovating a 3rd (top) floor apartment bathroom to create a walk-in shower. I need to create a step to elevate the floor level of the shower area to accommodate the height of the existing shower waste drain. I was thinking of doing this using concrete. The step-up slab will be 1050 x 1820 x 125 (mm). I plan to level the slab with 2-degrees of fall towards a recessed puddle flange sitting at the lowest point of the shower floor. I was then planning to apply a waterproof membrane (e.g. https://gripset.com/products/gripset-38fc) over the slab and walls prior to tiling so any water which penetrates the tiles hits the membrane and falls towards the puddle flange. I’ve seen PVC pan liners also used (e.g. https://youtu.be/Jl_CQ8jPMKE?t=742) in a similar situation though from what I can tell the plan I’ve described would be adequate and wouldn’t require this. Is the surface applied waterproof membrane adequate for a walk-in shower or should a PVC pan liner also be used?
