As part of a complete bathroom remodel, we are installing a tiled shower to replace a paneled shower with fiberglass pan that we have removed down to the studs. We haven't done this type of work before but follow direction well. : - )
We plan to build a mortar shower pan.We need advice and suggestions on how best to modify the existing shower drain plumbing to accomodate the new Oatey ABS drain for tile shower base.
Attached are pictures of the current setup.
Pictures 1 and 2 - Shows too large hole in existing plywood floor and existing riser. The water level of the drain trap sits at four inches below the top rim of the riser.
Picture 3 - Existing riser with Oatey drain assembly fitted on top. The ruler shows the distance from the subfloor to the drain assembly.
Question One - Since the hole in the existing subfloor is too big, should we install a half inch piece of plywood over the existing and cut out the four and one-half inch hole that is required, or is there a better way to get the correct size hole?
Question Two - It seems to us that approximately two and one-half inches of the existing riser needs to be removed to allow the flange of the tile base to sit on the subfloor. (Two inches if we install the additional half inch of plywood.) This will result in the water level of the drain trap sitting at approximately two inches below the top rim of the riser. Is this OK? If not, what do we need to do?
You folks are our "go to" guys for this project. Any help, advice or suggestions will be most appreciated.
