I’m taking a half-bathroom plus upgrading it to a full-bathroom.
This involves taking the closet inside, gutting out the shelves plus the wood sides, plus then putting in a shower stall.
Thankfully you can buy a shower stall that is almost totally assembled from the hardware store plus simply place it into the space where you want it. The hardest section is creating the hookups for the water access plus the drain. Thankfully I used to work in plumbing so I think how to do all of the work myself, otherwise I’d be spending a lot of money on work fees. Another strenuous section of this process is usually the time it takes to install tiles typically, but I’m avoiding that with the prebuilt shower stall. And since the lavatory vanity was updated before I bought the house, I’ll be mostly finished with our lavatory renovations once the shower is complete. The only other section of the process that I have to finish is adding an vent to the ceiling. When there was only a toilet plus a sink, I wasn’t uneasy about a lack of constant air flow to the lavatory as long as I kept the door open during the day plus evening. But once you start adding steam from the shower, it’s important to have air flow to the lavatory… This is especially important if you expect to keep the door closed while you’re in the shower. Adding an vent to the ceiling will provide constant access to dry conditioned air from the Heating, Ventilation, plus A/C system. Otherwise I’d have a recipe for lavatory mold.
