I live in a 1960's post and tention conrete high rise building where the plumbing for the master bathroom is all in one wall including the drainage for the toilet/shower/sink. The toilet is wall mounted. I have no access to running pipes through he concrete floor.
1) In this type of siutation, is it possible to move the toilet over along the same wall approximately 1 to 3 feet?
2) Currently there is only one sink and I would like to add a second sink next to the existing one. Is this possible?
3) Is it possible to add a tub in another location raising it off the floor to provide space below for drainage pipes. Is it possible to run water pipes inside the walls around corners and have a turn in the drainage pipe underneath in order to connect to the existing in the wall.
Thank you for for any feedback you may have!
