Hardwood Floor in Full Bath?
We are in year three of a 1900s Victorian house remodel in Wisconsin where we are refinishing all of the original hardwood floor in the house. Maple on the first floor, Fir on the second floor. We are converting a 2nd floor 1/2 bath into a full bathroom and would love to keep the old Fir floors into the bathroom.
We will be putting in a tub/shower, toilet, and double vanity. We have a 15 month old, so we need the tub (don't have one in the house).
Currently the T&G Fir floors are nailed directly to the joists with no subfloor. The gaps between the boards in the two rooms that have been refinished are very minimal, even in the winter.
My thoughts are to rip up the floor (have to anyways for plumbing and moving walls), polyurethane all sides of the boards, lay T&G Plywood, tar paper, then relay the old Fir floors with silicone between each T&G joint.
With a properly sized exhaust fan and general clean up of standing water, I think I should be ok. Any thoughts?
