Browse Forums Bathrooms and Laundry 1 Oct 16, 2016 1:51 pm Hi all, Very new to the renovation world and have spent many an hour researching DIY on google. We are currently converting our old laundry into a second bathroom and need some advice on the following topic. First of all, the project is all done on a concrete slab. We have cut the slab and laid the waste pipes. The shower design is a 1m x 1m corner diamond shape with hob wall and are using a channel drain. The problem is we don't have any fall back to the 50mm waste pipe. Obviously building a screed (which we plan on doing) will overcome this but I want to know do we install the puddle flange before or after the screed has been done? We plan to apply the waterproofing once the screed has fully dried. If the puddle flange is to be installed before the screed, do we still need to recess the puddle flange into the concrete? Thanks in advance, Luke Re: Laundry to bathroom conversion 2Oct 18, 2016 7:57 pm Hey Luke, no need to recess if if plan on waterproofing over the screed. It's usually only recessed when the membrane is installed over a level slab or floor, to insure water will find its way into the waste without interference from the lip of the flange. Good luck with it! Re: Laundry to bathroom conversion 3Oct 30, 2016 9:08 am Our Build123 Hey Luke, no need to recess if if plan on waterproofing over the screed.
