With a plan, budget and materials chosen we are ready to start the work. Often the most efficient way to run new plumbing and electric in a room is to remove all of the walls. To take the room to the studs. With the walls out it is faster to instal these systems. This can bring a cost savings on the plumbing and electric work. Changing locations of the toilet and shower means that parts of the floor must go also. Depending on the type of flooring material the floor may need to be strengthened. A tile floor will need more support than a floor covered in Marmolium. In this project the floor will be a 12×12 Carrara marble floor.
