I have back to back bathrooms. After discovering water damage, and that the wall around the tub, and the wall that seperates the bathrooms was filled with dirt. Literally, two feet of dirt PACKED into the wall and around the tub, sopping wet, hence the water damage.

Both bathrooms are small, no cabinets, wall mount sink etc. The MB bath has the only shower, the hall the only bathtub. All of the plumbing is in the wall that seperates the two bathrooms.

Right now, my bathrooms are shells. What we are left with are just the drains and supplies, is shown in this paint drawing(supplies arent shown, they are above each drain):


I would like to try to make the two bathrooms into one. If I can plug the shower drain, one of the toilet drains, and then remove the venting and piping, I would have enough room on the right side to create a doorway between the two rooms.

This is a diagram of showing the drain/vent lines, shown as if you were standing in the door way to the hall bath looking a the back wall. there are also a few copper supply lines that are not shown and go into the cement. The vents go into the cement as well.


My other option is to cut up the concrete floor and move the drains. From my reading, the hardest part is getting a hole in the concrete in order to use a concrete saw. Well, the hole is already there, after removing the tub we discovered a square cut in the concrete exposing the tub drain piping.

If it were your space, what would you do? Would you cut out the concrete and redo all of the piping, or close up the extra drains and work with the existing piping? Should I just put the two rooms back togeter as seperate bathrooms? Keep in mind, all of the piping that I can see is very corroded where the dirt was packed around it.

Sorry for the long post, but HELP! Im supposed to go pick up the new fixtures and all supplies today, but were not even sure what we are doing at this point, and we have no toilet!
