I want to install a molded shower in my basement. The nearest drain is the existing sink drain and the existing toilet drain. Is there a way to set up the shower drain to 'tee' onto the sink's drain?

You have two choices. Raise the shower and drain to the lavatory drain or break up the cement and tie into the lav drain underground. There is no other way. If you raise the shower by the time you figure in the trap and slope you're going to need steps to get in it. My bet's on door #2. Regards, Tom
