Project 1.2 – Master Bathroom Demolition

Our first task in remodeling this bathroom is to get rid of the existing sink, toilet and bathtub. The sink and toilet should be no problem, but we’ve never pulled out a bathtub before. I watched about  8 hours of HGTV and DIY Network before this, and have an idea of what I’m up against.

I cut it off, and installed a cheap compression style shutoff valve on both the hot and cold lines for the time being. The toilet shutoff valve leaks a bit, but it’s good enough for now. I’ll replace it before I get the subfloor cut out. We plan to install a pedestal style sink instead of another vanity, so the sink drain pipes will need to be reconfigured.

I removed the drywall on the wall behind the bathtub to expose the plumbing. Basically there’s a hot and cold line coming up thru the subfloor that go into the one-piece bathtub filler/diverter, and a line running from the diverter up to the shower head. The black pipe is the drain vent. I’m keeping my fingers crossed that the vent pipe doesn’t need to be disturbed when installing the new shower valve and shower head plumbing. I cut the water supply lines and temporarily capped them off with Sharkbite 1/2″ Push Fit end stops. I hear people say that the Push Fit (as opposed to crimping) stuff leaks, but the budget doesn’t allow for the $50+ crimping tool yet. With all the water lines shut and the toilet and sink removed, we take a look at the bathtub and figure out how to get it out of there.

The first think i did was remove the tub surround, which ran from the top of the tub to the ceiling. It was just glued to the drywall behind it, and stapled along the ceiling. It came out without much hassle. I also removed the drywall, opening up the bathroom to the bedroom and dining room.

From the dining room wall, I can see the tub’s drain connection:

I reached in to get a feel for what’s going on, and discovered that the tub drain isn’t even connected to the P trap! Well, one less thing to do. Looking at the tub, there are screws that go thru a lip around the top of the tub into the drywall behind it. Not much holding it in place. I removed as many screws as possible, but some were rusted so bad that the heads just crumbled. A little bit of muscle and a crowbar, and the tub was broken free. Having the wall to the dining room opened was a blessing .. we were able to turn the tub on it’s side and slide it between the studs, and then out the front door. Here’s what was left behind:

The hole for the drain plumbing was about 12×12, and we could see the ground underneath. Based on the number of mouse turds found on the floor under the tub, this must have been some sort of swanky mouse club.

Hopefully, rerouting the drain to that location won’t be much of an issue. I believe the lighter colored 2×6 can be moved back or brought forward as needed. I also plan on making the hole in the new subfloor much, much smaller than this! The hole is covered for now with a scrap piece of wood while we wait to start cutting out the floor.

We were fortunate not to find much mold during the demolition. The only bad spot was inside the wall next to the toilet that separated the bathroom from the bedroom. Once we take down the drywall on the outside walls, I expect that we’ll find more.
