This is especially crucial if you expect to keep the door closed while you’re in the shower
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 area is creating the hookups for the water access plus the drain. Thankfully I used to labor in plumbing so I guess how to do all of the labor myself, otherwise I’d be spending a lot of money on work fees. Another difficult area 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 lavatory vanity was replaced before I bought the house, I’ll be mostly finished with our lavatory renovations once the shower is complete. The only other area 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 upset about a lack of constant air flow to the lavatory as long as I kept the door open while both of us were in the day plus night. But once you start adding steam from the shower, it’s crucial to have air flow to the lavatory. This is especially crucial if you expect to keep the door closed while you’re in the shower. Adding an vent to the ceiling will supply constant access to dry conditioned air from the Heating plus Air Conditioning system. Otherwise I’d have a recipe for lavatory mold.
