Factors That Influence Sauna Costs
Sauna Type
Sauna types play a major role in determining price. Infrared models use infrared panels to heat the body directly, offering an energy efficient and lower temperatures experience that appeals to those who want to enjoy heat therapy without high temperatures. Traditional and infrared saunas each have their benefits, with traditional saunas offering steam, dry heat, and the ability to pour water over hot rocks for an immersive sauna experience. Many homeowners prefer traditional saunas for their authenticity, while others appreciate the convenience of infrared sauna units for in home sauna use.
Size and Capacity
A two person sauna will naturally cost less than larger saunas that seat six or more. Smaller home saunas are ideal for individual or couple use, while larger saunas require more materials, higher capacity sauna heaters, and additional square foot space, which can raise costs significantly.
Materials and Build Quality
High-end materials like nordic white spruce, cedar, or hemlock not only enhance the aesthetic but also influence the initial investment and durability. More materials and premium finishes, such as glass doors or integrated sound systems, can add more value to the sauna experience while increasing the overall cost.
Heating System
The sauna heater is the heart of the unit. Infrared panels in infrared sauna models are efficient and require less electrical work, while traditional saunas use either electric heaters or wood-burning stoves to produce dry heat or steam. The choice of heating system affects both installation costs and ongoing energy consumption.
Installation Costs
Sauna installation varies depending on location and type. Indoor saunas may require professional installation for electrical work, ventilation, and safety compliance. Outdoor sauna models need weatherproofing, a level foundation, and sometimes permits. Installing a sauna can be as straightforward as assembling prefab kits for portable saunas, or as complex as integrating a custom built sauna into an existing structure. Labor costs, site preparation, and additional considerations such as lighting or water access will all impact the final bill.
Brand Reputation and Warranty
Many sauna manufacturers offer warranties, but the length and coverage vary depending on the brand. Established names that provide robust warranties and high-quality customer service often justify a higher initial investment.
