In this day and age most home saunas initially arrive as a multi-part kit. Assuming you bought an infrared sauna kit, which is rapidly becoming one of the most common varieties to be had, your kit will include all special components necessary for a good sauna experience including: the benches, walls, hinged glass door, and the infrared emitting thin panels.
Other types of saunas exist with electric heaters that actually heat the air, but many people have begun to prefer the infrared because the panels take up so little space and because they emit infrared waves instead of heating up rocks they have less danger of catching fire and burning your sauna and your house down. While sauna kits can be setup standalone, many choose to surround them in dry wall in order to make them a real part of the home. Often these saunas are placed inside of a bathroom, or basement.
So what will you need to get started if you decide to go with a prefab home sauna kit? The basic tools are very simple. You’ll probably need: a hammer, a level, a measuring tape, a screwdriver, some pliers, and usually that is about it. Many of the sauna manufacturers today have made the experience of putting together saunas very simple because they’ve put a great deal of forethought into ensuring that their saunas don’t require a ton of experience working with wood.
