Converting a Laundry Room Into a Bathroom: Costs & Layouts

Your laundry room sits on the bedroom floor, or just off the kitchen, in exactly the spot where you’d use a second bathroom every day. Converting a laundry room into a bathroom is one of the cheaper ways to get that bath, because hot and cold supply and a drain already reach the room. That head start puts a half bath at roughly $10,000 to $18,000 and a full bath at $18,000 to $30,000.
