We just bought a house with a large, unfinished utility room in the basement, about 15 ft x 20 ft. The previous owner just used it for storage. It has washer/dryer hookups and contains the furnace and water heater; otherwise, it's mostly empty, with concrete floors.
We were thinking about finishing it with moisture-resistant drywall and using the extra space to install a small indoor hot tub.
Would this be possible to do? Or is it a bad idea, because the humidity in the room could rust, damage, or short out the appliances like the washer, dryer, furnace, and water heater?
The room does have a window, so we could open that whenever the hot tub cover is off in order to vent the steamy air; however, I'm still worried if this would be sufficient.
