Repurpose Closet Space (Dry Sauna)

I’ve been looking at houses and got thinking about what I would do with extra closets, one idea that came to mind was turning it into an infrared dry sauna. All you would need to do is insulate it and place oak or tiki wood down and buy a portable infrared heater then boom! There is your dry sauna. You can do this with any small space, for example putting a portable infrared heater in your boat or RV bathroom would add an extra luxury to your experience.
