There are two options for purchasing your own home or backyard sauna: prefab saunas (professionally designed, precisely cut, and partially assembled upon delivery) or a custom-made sauna. While a custom sauna provides much more freedom for fitting a sauna into your space, thanks to modern day designs, a prefab sauna kit can be relatively easy to install. Whether it’s an indoor sauna or an outdoor sauna, the primary factors to consider before buying is how much usable space is available, the flooring or foundation, and electricity. Indoor saunas need a good waterproof floor or foundation, and enough space for the sauna itself, as well as room for a tempered glass door or wooden door to swing open. For an electric stove, it’s essential to make sure that the sauna has adequate and safe electric hookups. Before buying an outdoor sauna kit, check with your local legislation to make sure you’re aware of regulations, building codes, or permits that might be required. Without the concern of making it fit into an indoor space, the top priority for installing a freestanding outdoor sauna is finding a safe and reliable source of power for the electric stove and lighting. No matter what you decide to buy, always check in with the manufacturer for a comprehensive plan and installation information.
