They are very popular because they are more affordable than infrared saunas and they offer a more authentic sauna experience.

If you are looking for an authentic and traditional sauna experience, then a wood-burning sauna is for you.

Just like the name suggests, these saunas use wood to generate heat.

Electric saunas are one of the most popular types of saunas because they are the most convenient.

You don’t have to worry about building a fire or anything like that. All you need is an electrical outlet and you are good to go.

And it should be at least 12 inches above the ground to protect the sauna from moisture. You also need to make sure that the wooden foundation is level and that it is big enough to support the weight of the sauna.

You can also build walls, doors, a roof, or benches with a wooden foundation. It is very versatile and it can be used for many different things.
