I live in Miami. Would anyone know how much it would cost to install a half bath, i.e., sink and toilet? I plan to have it installed in the laundry room which is on the other side of a full bath (divided only by wall board).
There is no set price for such an addition. It all depends on your situation, because there are various costs to deal with:
- permit, inspections
- rough plumbing
- types and styles of fixtures
- you need to make sure your laundry is big enough for a 1/2 bath.
What you need to do is get a plan, get bids from local tradesmen and compare.
As dj1 said there are to many variables to even be able to give you a good guess. Also being in Miami I'm sure your house is on a slab which would require cutting up the concrete floor.
