I’m replacing a leaking fiberglass shower with a custom tiled one in my basement. The old one is all ripped out and I am down to concrete floor with a 2” copper drain pipe extending up about 1 ¼”. (IMG_5557.jpg) I can’t seem to find a suitable drain. They all seem to be too big. They all seem designed to fit larger (and PVC, not copper) drain pipe, and also seem to be at least 4” high. (like drain1.jpg and drain2.jpg)
If I use something like a fernco fitting to add a length of bigger pvc to use one of these commonly available drains I’ll end up 6 or 7” above floor at least.
Is there some solution short of chopping out the embedding concrete floor? It seems a drain sort of like used for bathtubs, that slips down inside with a sealing collar would be great. But I haven’t seen anything like that suitable for a tiled shower, with weepholes.
