Let’s Build Your Ideal Sauna Space
Creating your personal sauna starts with understanding the two main types of heat: traditional steam and infrared warmth.
Traditional Finnish-style setups use electric or wood-burning heaters that warm rocks, letting you pour water for classic steam sessions. Infrared models use radiant panels that warm your body directly at lower temperatures. Both deliver genuine wellness benefits — your choice simply depends on how you like your heat and how you plan to use the space.
Indoor Sauna Kit Options
Full Spectrum Infrared Systems
Infrared technology works beautifully in existing rooms since these units require little to no remodeling. Full-spectrum panels provide steady, gentle warmth without the high heat of steam, making them ideal for smaller spaces or areas with limited ventilation. Compact one-person cabins fit neatly into corners or closets, while larger configurations comfortably accommodate multiple users.
Explore our complete Infrared Sauna Kits selection for ready-to-install packages that include everything needed for gentle, efficient heat therapy in compact spaces.
Electric Sauna Heaters
Electric systems like the Harvia Club and Delta SimpleSteam lines offer consistent, controllable heat with straightforward operation. Available in multiple kilowatt ratings — typically from 7.5kW for small rooms to 15kW for larger ones — these heaters deliver fast warm-up times and customizable temperature settings for your preferred intensity.
Outdoor Sauna Structures
Cube Design Kits
Freestanding cube models from SaunaLife combine clean design with lasting durability. These ready-to-assemble structures feature Thermory Spruce and Aspen interiors that naturally resist moisture while offering a bright, modern look. Available in 3-, 4-, and 6-person layouts, cube designs provide generous headroom and comfortable bench spacing — ideal for year-round outdoor use.
Our Outdoor Sauna Kits collection features complete freestanding systems with weather-resistant construction designed specifically for backyard installations and year-round outdoor use.
Wood-Burning Stove Packages
For purists who love the ritual of real fire, wood-burning models like the Harvia Legend and Harvia Pro bring authentic Finnish sauna tradition home. These stoves heat sauna stones for the satisfying steam you can pour water over, filling the space with the gentle aroma of burning wood. Larger stoves hold more rocks for extended sessions and larger groups.
Sizing Your Heater the Right Way
Proper heater capacity keeps your sauna efficient and evenly heated:
- Small Rooms (4–6 ft³): 6–8kW electric or compact wood stoves
- Medium Spaces (7–10 ft³): 9–12kW heaters
- Large Installations (11+ ft³): 13–21kW systems for complete coverage
For example, the Harvia Legend 240 SL delivers 21kW output — perfect for large outdoor builds — while the Harvia Spirit 10.5kW suits mid-sized cube saunas beautifully.
Assembly and Setup Considerations
Most sauna kits arrive with pre-cut panels and step-by-step instructions that make installation straightforward. Outdoor cube models generally take two people a weekend to assemble, while indoor infrared units often go together in an afternoon.
Traditional setups require proper ventilation and electrical wiring rated for the heater’s power, so it’s worth checking your home’s setup before you begin.
Modular construction makes it achievable for DIY builders, panels lock into place, benches mount easily, and heaters connect through simple electrical or venting procedures. Browse our full range of Sauna Kits to compare traditional steam systems, infrared options, and complete packages designed for various installation requirements and space configurations.
Built for Longevity
High-quality woods like Thermory Spruce and Aspen are thermally treated for superior moisture resistance and dimensional stability. This process prevents warping, reduces maintenance, and extends your sauna’s lifespan. Stainless steel hardware resists corrosion — especially important for outdoor builds — ensuring your sauna stays beautiful and functional for years to come.
Frequently Asked Questions
What's the difference between infrared and traditional steam saunas?
Traditional systems use heaters to warm air and rocks for steam, reaching 150-195°F. Infrared models use panels that warm your body directly at 120-150°F, requiring less ventilation and working well in existing rooms.
How long does assembly take for outdoor sauna kits?
Most outdoor cube designs assemble in one to two days with two people. Pre-cut panels and clear instructions simplify construction, and you'll need basic tools for connecting sections and mounting components.
Can I install an electric sauna heater myself?
Electric heaters require proper electrical connections rated for their kilowatt output. Review your home's electrical capacity and consult a licensed electrician to ensure safe installation that meets local building codes.
What size heater do I need for my space?
Calculate roughly 1kW per 45-50 cubic feet of interior volume. Smaller rooms need 6-8kW, medium spaces work with 9-12kW, and large installations require 13kW or higher for adequate heating performance.
Do wood-burning stoves need special installation requirements?
Wood-burning models like Harvia Legend stoves require proper venting through walls or roofs, clearance from combustible materials, and appropriate flooring protection. Check local regulations for wood-burning appliance installations in your area.
