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