Browse Forums Bathrooms and Laundry Re: Connect shower drain with limited sub floor access? 3Mar 18, 2020 8:48 am Stewie D When the old flooring has been ripped up, as part of the rough-in you install all the waste pipes and traps with them coming up through the floor. You lay the sheeting and cut out neatly around the shower and floor waste pipes then cut them off flush with the flooring. The waterproofing then is applied and then down about 20mm at least into the pipe. Stewie Thanks Stewie, The problem is attaching the threaded trap to the floor drain (one piece shower base) once the flooring is down with no sub-floor access. I did ask elsewhere and someone mentioned a 'Smartpan' from Reece. I checked it out, it would have worked with a different trap and drain fittings but it's quite big and would have pushed the waste pipe in the wrong direction for the fall. I ended up fitting most of the flooring and AC sheeting, leaving a small gap, then temporarily removed a noggin to give me just enough room to squeeze underneath. No for the claustrophobic but it'll work.
