Then design a bathroom layout that will function properly with the existing plumbing plan or with limited modification.
Batjroom floor over concrete slab.
In order to add a bathroom to a house on a concrete slab you will need to locate the existing water supply and waste lines.
A foam underlay is placed over the concrete and the planks are then clicked into place in a tongue and groove pattern.
The ideal way to put down a wood floor over concrete that is subject to dampness is to first put down pressure 2 by 4 inch sleepers or lengths of wood on the floor that are spaced 16 inches apart on center.
Many types of flooring can be installed over a concrete sub floor.
Laminate flooring is also fairly easy to install.
Cover the sleepers with 6 millimeter plastic and then lay down 5 8 inch plywood.
Laminate flooring is a good alternative to wood flooring in basements.
Sketch the new design in place if possible fine tune the design and then finalize the plan.
Any cracks in the surface of the slab need to be repaired before you begin as well.
