We are about to finish our basement, and there is a 6x8-foot cubbyhole that we are thinking about turning into a secret room, probably hidden behind a bookcase door like this. The room has concrete walls on three sides, with no windows.
The problem is that although the concept of a secret room is incredibly cool, we don’t have any great ideas about what to do with it. My first thought was a hot tub. We loved the outdoor hot tub at our last house and would love to have one here, too. However, I’ve read that indoor hot tubs can be problematic: you have to ventilate and dehumidify the space carefully, and that can be expensive. Also, a very large space elsewhere in the basement is set aside for a bathroom, and it might be a better location for a hot tub, if we decide to go that route.
I’ve never used a sauna, but I don’t think I’d care for it, and I suspect it would be much more expensive than a hot tub, and have all the same humidity issues.
We have three grandchildren, ages 5 years, 2 years, and 4 months, and some kind of playroom would undoubtedly be quite thrilling for them. But since they only visit once a year or so, it seems a bit extravagant to spend a few thousand bucks for such a limited purpose.
We don’t need a safe room or a bomb shelter, and although my wife likes wine, we could never hope to use a space that large as a wine cellar. Another section of the basement is set to become the home theater, so TV room is out. And since we’re in the neighborhood of 60, so is “adult entertainment center.” (Which would be a bit awkward to explain if the grandkids happened to find it.)
So what options can you suggest?
