Great idea

! Our last house had a sauna, it was awesome. We had a walk-in basement, and I water-tighted a chest freezer and made a cold dip, so you could go from the sauna to the freezer. We also had an outdoor cast-iron cold dip, too, but the freezer was the best. I really miss that. That freezer is back to its original purposes, but I will definitely get one going again. I could do a cold dip and look out into the garden. It was lovely.
Hmm, I could definitely integrate the cold dip/changing foyer area with a lot of plants/make it a mini greenhouse. That might work really well!
