BATHROOM ADDITION 5-8
The price for such a project does not include the cost of finish materials and would approximately be: $450 - $575 per square foot or $18,000 to $23,000.
This scenario illustrates the addition of a new 5'x8' bathroom onto the side of an existing house over a crawlspace.
We would demolish a portion of the house's exterior wall where the new bathroom would connect to the existing house and we then would construct framing for the walls, floor, and roof/ceiling and mount the structure on concrete footings. We would add sheathing and drywall on the walls, floor, and ceiling and install plumbing, drainage, and electricity lines in the manner described in the "Our Bathroom Remodeling Process" section above. We would also install the door and any windows. Once the structure and walls have been finished, we would proceed to install a tub/shower combination, a vanity, a toilet, a tiled floor and walls, lights, and miscellaneous bathroom accessories, in addition to painting the walls and ceiling.
