Fortunately, there are several heating solutions for DIY saunas, each with special qualities and benefits. Knowing your options will enable you to choose the one that most closely matches your unique requirements and preferences.

3 Main Types of Sauna Heating Systems

The three main types of sauna heating systems frequently seen in home saunas are as follows:
