My son needs to replace a bathtub, and his home is built on a slab. Estimates have been about $1000. My question is my husband who is very very handy is a little hesitant about dealing with a slab. How hard is it to replace the tub on the slab? Husband has already done many plumbing projects including adding a bathroom to my basement in a previous home, however he is a little nervous about this project to help my son. Can anyone help us as to the difficulty of this project.
