Subfloor Repairs in 2nd Floor Bathrooms

HAPPY INDEPENDENCE DAY!

Yesterday, John worked on the 4″ tongue and groove subfloor in the two upstairs bathrooms. The hall bathroom’s original tub was heavy and had caused damage over the years to the original subfloor. John pulled it out and replaced with new 3/4 plywood.

It’s getting to the exciting part when I can design the bathrooms, choose tile, fixtures, color scheme, shower and tub enclosures, vanities, etc. I’m constantly perusing the Internet for bathroom design inspiration and looking at tile options. Mosaic tile is definitely on the list for one of the bathrooms. (The house has the two existing bathrooms and will have the new master bath in the soon-to-be-built addition).

The above photo is Bill’s original master bathroom directly above the patio door (the bedroom windows look down onto the patio).  Note: I’m now thinking the walled-in-patio is more of a courtyard because the walls will remain at the height they’re at now (present height is code).

With a T-square (to mark it) and a circular saw, John cut the existing bathroom subfloor to insert the new 3/4 plywood.

He’ll take out the cast iron stack (below) and use PVC, which will be used for both bathrooms. The floor needed to be prepped and strengthened now for when the plumber and HVAC contractors come in and rough in their work; they’ll do their work after the framing is complete.

Here’s the new 3/4 plywood in the hall bathroom. This is a longish, narrow bathroom and will also be used by guests. I really want this bathroom to have a wow factor, and because it’s narrow, I can get a little extra creative due to the layout.

The tub will be on the right and the commode straight ahead (underneath a narrow window). This window also looks over the patio/courtyard. Both bathrooms are side by side.

With three bedrooms upstairs, one will have it’s own bathroom, the second bedroom will use the hall bath, and the third and smallest bedroom, will be a cozy office/computer room.

In Bill’s bathroom (above patio door), the joist that John’s foot is on has to be replaced. Back in the 80s, someone had cut through the joist to install the shower pan when the bathroom was added. Originally, when the house was built in 1954, it only had the hall bathroom, typical for the time.

Because of the 3/4″ plaster walls, Bill had no way to run his wiring for all of his electronic endeavors (i.e. ham radio, computers, etc.) so the bundle of wires in the photo was directed downstairs through a 3 1/2″ plate, which John had to cut with a chisel to eradicate the wiring. There was wiring EVERYWHERE.

When we install the 200 amp service, the power will be shut down and John will cut every foot of wire out of the house and then put down the sheet of plywood just as he did in the hall bath.

It took three sheets of plywood to repair the two bathroom floors with some scrap pieces left over to be used elsewhere.

This is the upstairs hallway (bathroom above patio door is behind John) and the hall bath is to the right in the forefront. John is pointing to the original roof sheathing that is buckled due to the heat. The 1/2 inch sheathing had no gaps between each piece–1/8″ is needed to allow breathing; this needs to be replaced.

Be safe on this 4th of July weekend!
