    Default Need advice on best way to redo drain for walk in shower

    Hi,

    I am redoing our master bath and have to move the shower drain for a new walk in. Attached is a pic of what I am dealing with. The new drain has to be right where there is a half circle drawn on the plywood just under the existing on. Everything has to be done in the same joist cavity and being only 10.5" I am very limited in space to make the p-trap and drain properly. If I make the p-trap go towards the left and then come back to the right to connect into the main drain, will there be issues of slow draining or clogging? I will use 2" ABS and the main drain is a 3" ABS coming from the right and with a 90 degree going to the downstairs floor which I don't have access to. In the pic it may look like the 3" ABS is leading into the drain all the way to the right (existing shower drain) but its not. The existing shower drain is connected at about 16" from the beginning and goes into the next joist cavity

    Looking for opinions please ASAP

    Can't really see the mark indicating where you want the trap nor have a good idea of the shape and size of the shower you want to build. There will be no issue with having the inlet and outlet of the trap rotated (folded) as long as you don't throw additional elbows into the equation. For maximum strength, you want any patches in your ply to span at least three joists. That way, the middle (at least) of the ply is supported, and it is not hanging just by the edges and the fasteners on 1/2 of a joist width. This can be an issue when you want cement and tile on top of the surface.

    On a conventional shower, it's nicest to have the drain as close to the middle of the shower as possible. On an ADA, curbless shower (is that what you're talking about doing), it's nice to do something like a linear drain against say the back wall of the shower.

    its a prefab shower base from shluter and the drain is offset not centered. the mark (semi-circle) is about 1ft to the left of where the plywood starts on the right. If you still can't see it I will try to edit the photo (if I can figure out how).

    its a schluter drain. I can't really do much from downstairs since its a supporting wall and a division wall runs right up to where the 3" drain is. I opened a small little section to sweat a copper to pex transition and at same time see if I can do anything on the drain but no luck on that one. Any other suggestions to work on it the way it is? The shower will be 40x84 and drain will be approx at 20"x20". You actually walk in from the other side and plan to have a no door, glass walk in.
