This unique barrel sauna concept comes with an acrylic bubble back wall that allows you to see the beautiful view of you lake or landscape from inside the sauna. Made of Western Red Cedar, these barrel saunas have 1 1/2″ thick walls for a long natural insulation and the barrel design give you a much smaller heating area than any rectangular sauna with plenty of room for bathers. If your barrel sauna is going to be located outdoors in the direct weather, we recommend adding a roof option with your purchase. Of course you also construct your own roof cover if preferred.
