It's seldom that you buy a product new to you, and it totally exceeds your expectations. The best thing I've bought for ages is a home sauna. It's basically a foldable tent made of tough fabric, together with a 1200w steam heater. It gets pretty hot and steamy in there, and you feel very refreshed and relaxed afterwards. Best of all, its a great way of getting trunks and t-shirts wet! It doesn't cost much to run, as I've noticed that after using it for half and hour my thermostatic electric heating comes on less, so the overall consumption of power is much the same.

It's a different set up to my home made sauna, I use a plastic garden greenhouse, and a wall paper steam stripper to get it hot and sweaty inside
