RTA Saunas
Experience the health benefits and relaxation of authentic sauna bathing in your own home with ready-to-assemble saunas that make ownership accessible and installation straightforward. Our collection eliminates the complexity, extended timelines, and premium costs traditionally associated with custom sauna construction. These engineered systems arrive with pre-cut components, comprehensive instructions, and everything needed to create professional-quality sauna spaces without specialized contractors or months of construction.
The RTA Advantage
Ready-to-assemble saunas revolutionize how homeowners approach sauna ownership. Traditional custom-built saunas require experienced contractors, lengthy construction periods, and significant budgets. RTA systems condense this process dramatically. Precision manufacturing ensures components fit together accurately. Pre-finished panels eliminate on-site woodworking and finishing. Modular designs allow capable DIY enthusiasts or general contractors to complete installations in days rather than weeks. The cost savings are substantial—often 40-60% less than equivalent custom construction—making sauna ownership achievable for broader audiences.
Quality Without Compromise
Reduced cost and simplified installation don't mean sacrificed quality. Premium RTA saunas use the same high-grade woods, insulation materials, and heating systems found in custom installations. Tongue-and-groove joinery creates tight seals that retain heat efficiently. Multi-layer wall construction with proper insulation ensures energy-efficient operation. Quality glass doors with insulated properties maintain temperature while providing visibility. The difference lies in manufacturing efficiency and direct-to-consumer distribution rather than reduced material quality or performance.
Wood Species and Interior Aesthetics
The wood species forming your sauna interior dramatically affects both appearance and performance. Our collection features several premium options, each with distinct characteristics.
Nordic Spruce and Hemlock
Light-colored softwoods like Nordic spruce and Canadian hemlock create bright, airy interiors with subtle grain patterns. These woods remain comfortable to touch even at high temperatures due to low density and thermal conductivity. The light coloring reflects heat and light effectively, making compact saunas feel more spacious. These species resist warping and splitting in high-heat environments while offering pleasant, mild aromatic qualities. Their affordability makes them popular choices for first-time sauna owners.
Cedar
Western Red Cedar brings rich color and distinctive aroma to sauna interiors. The wood's natural oils provide inherent resistance to moisture, decay, and insects—ideal for the sauna environment. Cedar's moderate density keeps surface temperatures comfortable while its beautiful grain patterns and warm tones create inviting spaces. The aromatic oils released during heating add sensory dimensions to the sauna experience. Cedar represents an excellent balance of performance, beauty, and value.
Aspen and Abachi
For those preferring minimal aroma or lighter colors, aspen and abachi (African hardwood) offer excellent alternatives. These woods remain exceptionally cool to the touch even at peak sauna temperatures, making them ideal for bench surfaces. The very light, almost white coloring creates Scandinavian-style minimalist aesthetics. Aspen provides North American sourcing, while abachi delivers tropical hardwood durability. Both resist splintering and maintain smooth surfaces through years of use.
Size Range for Different Spaces
RTA saunas come in configurations ranging from compact one-person units to spacious rooms accommodating six or more bathers. Understanding your available space and typical user count guides appropriate sizing.
Compact Personal Saunas
Small saunas measuring 3x4 feet or 4x4 feet fit in closets, spare bathrooms, or basement corners. These space-efficient units accommodate one to two users comfortably. While intimate, they deliver authentic sauna experiences with proper heating and insulation. Compact models suit individuals, couples, or those with severe space constraints who refuse to sacrifice sauna ownership.
Mid-Size Family Units
Saunas in the 4x6 to 5x7 foot range provide comfortable capacity for two to four users. These dimensions suit most residential applications, fitting in dedicated basement rooms, converted closets, or outdoor structures. The added space accommodates benching at multiple levels, allowing users to choose their preferred heat intensity positions. Mid-size saunas balance spatial efficiency with genuine comfort for small groups.
Spacious Multi-User Rooms
Larger saunas exceeding 6x8 feet create spa-like environments for families or social sauna bathing. These substantial rooms include extensive benching, potentially at two or three height levels, allowing six or more users to enjoy sessions together. The generous dimensions also benefit solo users who appreciate spacious, luxurious environments. Such saunas require dedicated rooms but deliver commercial-quality experiences.
Indoor and Outdoor Installations
RTA saunas adapt to both interior and exterior locations, each offering distinct advantages.
Indoor Placement
Interior saunas integrate seamlessly into home layouts, accessible year-round regardless of weather. Common locations include basements, spare bedrooms, large bathrooms, converted closets, or dedicated wellness rooms. Indoor installation simplifies electrical connections and climate control. Proper ventilation is essential—saunas require fresh air intake and moisture exhaust to prevent condensation damage to surrounding structures. The convenience of stepping from sauna to shower makes bathroom or basement fitness room locations particularly appealing.
Outdoor Structures
Outdoor saunas create destination experiences in gardens or beside pools. They can occupy corners of yards, position near hot tubs or swimming pools, or stand as focal points in outdoor living areas. Outdoor placement eliminates indoor ventilation concerns and humidity impacts on interior spaces. The ritual of moving between hot sauna and cool outdoor air (or cold plunge pools) delivers invigorating contrast therapy. Outdoor saunas require weather-resistant exteriors and protected electrical installations but offer unmatched ambiance.
Heating Systems
The heater represents your sauna's heart, generating the heat and humidity that define the experience. RTA saunas accommodate various heating technologies.
Traditional Electric Heaters
Electric sauna heaters with rock chambers provide authentic Finnish-style experiences. They heat volcanic or ceramic rocks to high temperatures; ladling water over these rocks creates löyly—the burst of humid heat central to traditional sauna culture. Electric heaters offer reliable, consistent performance with straightforward installation. They require dedicated 220-240V electrical circuits but provide precise temperature control and relatively quick heat-up times. Rock capacity affects steam generation and heat retention.
Infrared Heating Panels
Infrared saunas use carbon or ceramic panels that emit infrared radiation, warming bodies directly rather than heating air intensely. These saunas operate at lower temperatures (120-140°F versus 160-200°F for traditional) while still promoting sweating and relaxation. Infrared systems use standard 110-120V electrical service, heat up quickly, and consume less energy. The experience differs from traditional saunas—drier with less intense ambient heat. Some users prefer this gentler approach, while traditionalists favor conventional heating.
Wood-Burning Options
For outdoor saunas or off-grid properties, wood-burning heaters provide authentic old-world experiences. These heaters require no electrical service, creating independence from power infrastructure. The ritual of fire-tending and the subtle smoke aroma add rustic charm. Wood-burning heaters demand proper venting through chimneys or flue pipes, requiring more complex installation. They're typically not suitable for indoor residential locations due to ventilation and code requirements.
Insulation and Energy Efficiency
Proper insulation determines heating efficiency, operating costs, and temperature stability. Quality RTA saunas incorporate multiple insulation strategies. Wall panels include insulation layers between interior and exterior surfaces—often foil-backed for radiant heat reflection. Floors feature insulated bases that prevent heat loss downward. Ceilings include substantial insulation since heat naturally rises. Weather-stripping around doors prevents air leakage. These combined measures allow smaller heaters to maintain comfortable temperatures while reducing energy consumption and operating costs.
Bench Configuration and Ergonomics
Sauna benching significantly affects comfort and usability. Most saunas include two or three bench levels at different heights. Upper benches position users in hotter air zones for intense sessions. Lower benches provide cooler positions for gentler experiences or acclimatization. Bench depth should accommodate comfortable sitting or reclining—typically 18-24 inches. Ergonomic designs include backrests and contoured surfaces. Quality benches use vertical slats with gaps that prevent heat concentration and allow air circulation beneath bathers.
Glass Doors and Windows
Modern RTA saunas typically feature glass doors that provide visibility while maintaining thermal efficiency. Tempered glass withstands temperature extremes safely. Bronze or gray tinting reduces heat transmission while adding visual appeal. Insulated glass units (double-pane) offer superior thermal performance compared to single-pane glass. Full glass doors create open, inviting appearances, while partial glass maintains some traditional enclosure. Small windows in walls provide additional light and visibility without compromising wall insulation.
Lighting for Ambiance and Function
Appropriate lighting enhances both safety and atmosphere. Traditional incandescent fixtures with protective enclosures provide warm, functional illumination. LED systems offer energy efficiency and don't add heat load—advantageous in the already hot environment. Color-changing LEDs create chromotherapy experiences, with different colors purportedly offering psychological benefits. Dimming capabilities allow adjustment from bright task lighting during cleaning to subdued mood lighting during sessions. All fixtures must be rated for high-temperature, high-humidity sauna environments.
Ventilation Requirements
Proper ventilation ensures fresh air supply and prevents excessive humidity in surrounding spaces. Intake vents near floor level behind or below heaters draw fresh air that rises as it heats. Exhaust vents positioned high on opposite walls allow hot, humid air to escape. This circulation prevents stuffiness and oxygen depletion while moderating humidity. For indoor saunas, exhaust may connect to ductwork venting outdoors. Outdoor saunas rely on simple vents and door gaps. Adequate ventilation protects sauna longevity and user comfort.
Assembly Process and Timelines
RTA saunas typically arrive on pallets with numbered panels, hardware kits, and detailed instructions. Assembly involves connecting wall panels in proper sequence, securing them to floor bases, installing ceiling panels, mounting benches, positioning doors, and connecting heaters. Two moderately handy people can usually complete assembly in 4-12 hours depending on sauna size. No specialized tools beyond standard household supplies are needed. The process resembles large furniture assembly rather than construction—following systematic instructions rather than interpreting plans.
Electrical Requirements
Traditional electric saunas require dedicated electrical circuits—typically 220-240V service with amperage matching heater specifications. Licensed electricians should perform these connections, ensuring code compliance and safe operation. Infrared saunas using 110-120V service may plug into standard outlets if circuits have adequate capacity, though dedicated circuits remain advisable. Outdoor saunas require weather-protected electrical installations with appropriate wiring methods for exterior applications.
Flooring Considerations
Sauna floors must tolerate heat, moisture, and temperature fluctuations. Concrete provides excellent substrates for sauna installations. Ceramic or porcelain tile creates attractive, easily cleaned flooring. Wood floors work if properly protected from moisture. Many RTA saunas include insulated floor panels that install over existing flooring, creating thermal barriers while providing finished surfaces. Raised wooden slat floors (duckboards) provide comfortable standing surfaces while allowing drainage and air circulation beneath.
Accessories and Enhancements
Complete your sauna with accessories that enhance function and enjoyment. Thermometer and hygrometer combinations monitor temperature and humidity. Sauna buckets and ladles enable water application to rocks. Sand timers track session duration without electronics. Backrests improve reclining comfort. Headrests support relaxed positioning. Essential oil dispensers add aromatherapy dimensions. Audio systems provide musical accompaniment—speakers must be sauna-rated for high temperatures.
Health Benefits and Wellness
Regular sauna use provides numerous documented health benefits. Heat exposure elevates heart rate and circulation similarly to moderate exercise. Profuse sweating eliminates toxins and cleanses skin. Muscle relaxation aids recovery from physical exertion. Stress reduction comes from quiet, meditative heat sessions. Improved sleep often follows evening sauna use. Respiratory benefits may occur from warm, humid air inhalation. While not medical treatment, consistent sauna bathing contributes to overall wellness routines.
Maintenance and Longevity
RTA saunas require minimal maintenance for lasting performance. Wipe down benches and walls after use to remove perspiration. Periodic deep cleaning with mild solutions maintains appearance. Leave doors open after sessions allowing interiors to dry completely. Check and tighten hardware annually as wood expansion and contraction may loosen connections. Inspect heating elements and replace sauna rocks every few years as they deteriorate. With basic care, quality RTA saunas provide decades of reliable service.
