Auroom Saunas: Complete Buying Guide

For those seeking the pinnacle of sauna craftsmanship, Auroom represents an exceptional fusion of centuries-old Estonian sauna traditions with contemporary design innovation. As a subsidiary of Thermory — the world's leading producer of thermally modified wood — Auroom has established itself as a premier manufacturer of luxury ready-made saunas that transform any space into a sanctuary of relaxation and rejuvenation.

This comprehensive guide explores everything you need to know about Auroom saunas, from the company's rich heritage to detailed overviews of every model available at Sauna Republic, helping you select the perfect sauna for your home.

The Auroom Story: Estonian Craftsmanship Meets Modern Wellness

Auroom emerged from the heart of Estonia, a Baltic nation where sauna culture has flourished for thousands of years. Established formally as an independent company in April 2021 after being spun off from Thermory AS, Auroom brought with it decades of accumulated expertise in premium wood manufacturing and sauna construction.

The company's production facilities are located in Tartu County, Estonia, where skilled artisans with over 20 years of experience meticulously craft each sauna. The name "Auroom" itself evokes the concept of a golden sanctuary — a place where warmth, wellness, and exceptional quality converge to create moments of profound relaxation.

What distinguishes Auroom from other sauna manufacturers is their unique position within the Thermory Group. This relationship provides Auroom with exclusive access to the highest quality thermally modified timber in the world, ensuring consistent material quality even for large orders. Every piece of timber used in an Auroom sauna undergoes rigorous selection to guarantee longevity, aesthetic beauty, and optimal performance in high-heat environments.

Understanding Thermally Modified Wood: The Foundation of Auroom Quality

At the core of every Auroom sauna lies thermally modified wood — a revolutionary material that has transformed the sauna industry. Thermal modification is an eco-friendly process that treats wood using only heat and water vapor at temperatures exceeding 200°C (392°F). No chemicals, fungicides, or pesticides are used, resulting in wood that is completely safe for human contact and the environment.

The thermal modification process fundamentally changes the wood's cellular structure, delivering several critical benefits for sauna applications. The wood becomes significantly more dimensionally stable, meaning it resists warping, cupping, and shrinking even when exposed to the extreme temperature and humidity fluctuations typical in saunas. Moisture absorption is dramatically reduced, which prevents the rotting and decay that can plague untreated woods in wet environments. The process also enhances the wood's natural beauty, producing rich, warm tones that deepen over time.

Auroom primarily uses several species of thermally modified timber, including thermo-aspen, thermo-spruce, and thermo-alder. Thermo-aspen provides a silky-smooth texture that feels gentle against bare skin, thermo-spruce offers exceptional durability for exterior applications, and thermo-alder presents a warm, honey-toned appearance with excellent thermal properties. For customers who prefer natural wood options, Auroom also offers saunas constructed from untreated aspen that provides a characteristic natural aroma and lighter, more traditional aesthetic.

Auroom's Commitment to Sustainability

Environmental responsibility is woven into every aspect of Auroom's operations. The company sources all timber from sustainably managed forests in Northern Europe, where strict forestry regulations ensure responsible harvesting practices. Auroom holds ISO 9001, ISO 14001, and ISO 45001 certifications, demonstrating their commitment to quality management, environmental management, and occupational health and safety. Production facilities utilize renewable energy sources, and packaging materials prioritize recyclable and biodegradable options. Even the sauna heaters recommended for Auroom saunas — including models from Harvia, HUUM, and Saunum — are selected for their energy efficiency and reliability.

Auroom Indoor Sauna Collections

Auroom's indoor sauna lineup represents the perfect solution for transforming any space in your home into a personal wellness retreat. Sauna Republic carries six distinct indoor model lines across 24 configurations, ranging from a compact 1-person solo retreat to spacious 6-person family saunas. Each model is designed with careful attention to ergonomics, aesthetics, and functionality.

The Cala Series: Compact Excellence

The Cala series proves that exceptional sauna experiences don't require excessive space. Designed to be compact while maximizing interior comfort, the Cala models feature full-glass fronts that create an expansive, open feeling despite their modest footprints. Natural light permeates the space through full-height glass doors and walls, preventing the claustrophobic feeling that can accompany smaller saunas. A wax finish adds protection and visual warmth, while the straightforward setup and low energy demands make the Cala one of Auroom's most accessible lines.

The Auroom Cala Mini is the ultimate space-saving solution — a comfortable 1-person sauna perfect for apartments, bathrooms, or dedicated wellness rooms with limited square footage. Step up to the Cala Glass 59×59 for a 2-person retreat, the Cala Glass 59×71 for three bathers, or the Cala Glass 59×79 for the largest Cala configuration. All Cala Glass models are available in Aspen or Thermo-Aspen finishes. Get Pricing on any Cala model.

The Baia Series: Ergonomic Innovation

The Baia series stands apart through its focus on ergonomic comfort. Each Baia sauna comes standard with distinctive curved, wavy benches that cradle the body in natural comfort — an ergonomic seating design typically found only in larger luxury saunas. This provides superior support during extended sauna sessions and adds a sculptural element to the interior design.

The Auroom Baia features a warm wood front for a traditional appearance, available in Aspen or Thermo-Aspen. The Auroom Baia Glass adds a modern glass front that opens the interior visually and pairs beautifully with contemporary spaces. Get Pricing on either Baia configuration.

The Vulcana Series: Modern Sophistication

The Vulcana series exemplifies Auroom's commitment to contemporary design excellence. Featuring clean lines, contrasting dark and light elements, and premium materials throughout, the Vulcana transforms any room into a sophisticated spa environment. A distinctive aluminum base frame ensures structural integrity and longevity, while the innovative through-glass air intake vent maintains optimal ventilation without compromising the sleek aesthetic.

Choose from three configurations: the Vulcana 59×59 for a compact 2-person luxury retreat, the Vulcana 59×79 for families or those who enjoy sharing the sauna experience, or the Vulcana 79×79 — the largest configuration, ideal for entertaining or semi-commercial wellness spaces. Get Pricing on any Vulcana size.

The Familia Series: Classic Versatility

The Familia series represents Auroom's most versatile indoor offering — and it's the widest size range in the entire collection. Available in five configurations and three beautiful wood finish options, the Familia adapts to virtually any space and design preference. The classic design ensures broad appeal while the range of customization options allows for personalization that matches your interior.

The Libera Glass Series: Freedom Meets Elegance

The Libera Glass series embodies the concept of freedom and openness. The expansive exterior glass wall transforms the sauna experience by creating a visual connection with the surrounding space while maintaining the heated sanctuary within. This design approach is particularly effective in rooms with views, home gyms, or spaces where the sauna serves as a centerpiece. Five sizes span from an intimate 2-person retreat to a grand 6-person family installation.

The Libera Wood Series: Warm Sophistication

For those who love the Libera's designer proportions but prefer the warmth of a wood facade over glass, the Libera Wood delivers the same generous interior and premium construction with a beautifully finished wood front wall. The wood exterior adds natural texture and a sense of warmth that integrates effortlessly into traditional and transitional interiors, while still featuring the Libera's signature full-height glass door for light and visibility. Like the Glass variant, it's available in five sizes from 2 to 6 persons.

Auroom Outdoor Sauna Collections

Auroom's outdoor sauna lineup brings the authentic Finnish sauna experience to your backyard, garden, or outdoor living space. Each model is engineered to withstand the elements while providing the same exceptional quality and comfort found in their indoor counterparts. Outdoor models range from compact 2-person kits to fully assembled cabins with dedicated changing rooms.

The Mira Series: Glass-Front Magnificence

The Mira series showcases Auroom's craftsmanship through expansive full-glass front walls that reveal the elegant thermo-aspen interior. This design creates a dramatic visual statement while allowing natural light to fill the sauna space. The contrasting exterior finishes — available in natural wood or sophisticated black — complement various landscape designs and architectural styles.

The Auroom Mira S is a compact 2-person design perfect for smaller yards or intimate settings. The Auroom Mira L opens up to a spacious 5-person interior for family or group use.

The Garda Series: Pre-Assembled Convenience

The Auroom Garda arrives pre-assembled using advanced cross-laminated timber construction, dramatically simplifying installation.

The Terra Series: Universal Style

The Terra represents Auroom's universally-styled outdoor sauna, designed to complement any architectural context. The thermo-pine exterior is available in natural or black finishes and weathers beautifully over time.

Assembly Options: DIY Kits and Pre-Assembled Models

Auroom offers two primary assembly formats to accommodate different preferences and capabilities. The DIY sauna kits provide all components necessary for assembly — pre-cut timber, hardware, glass elements, and detailed instructions. These modular kits are designed for efficient assembly by homeowners with basic DIY skills, and every Auroom sauna is fully assembled at the factory before shipping to verify that all parts fit perfectly. Two people can typically complete an indoor kit in 4 to 6 hours.

Pre-assembled outdoor saunas like the Garda, Terra, and Arti arrive substantially complete, requiring minimal on-site work. This option is ideal for customers who prefer turnkey solutions or have limited construction experience. The pre-assembled units utilize innovative cross-laminated timber construction that maintains structural integrity during transport while simplifying final installation. For help deciding between indoor and outdoor placement, read our dedicated comparison guide.

Selecting the Right Sauna Heater

Auroom saunas are sold without heaters to provide maximum flexibility in choosing the right electric sauna heater for your needs. The heater must be properly sized for your sauna's interior volume — generally, allow approximately 1 kW of heater power per 50 cubic feet of sauna volume, though factors like glass coverage and insulation quality can influence this calculation. Our sauna electricity cost guide covers everything your electrician needs to know.

Three heater brands pair exceptionally well with Auroom saunas:

For a detailed comparison of heater options, read our best sauna heaters comparison or our head-to-head Harvia vs HUUM review. For those interested in traditional steam bathing with löyly (the burst of steam when water is thrown on hot stones), selecting a heater with generous stone capacity — like the HUUM DROP at 122 lbs — is essential.

The Health Benefits of Regular Sauna Use

Investing in an Auroom sauna delivers meaningful health benefits supported by extensive scientific research, particularly from Finland where sauna bathing has been studied for decades. Cardiovascular health receives significant support — studies have shown that frequent sauna bathing is associated with reduced risk of cardiovascular disease and improved circulation. The heat exposure causes blood vessels to dilate, improving blood flow and temporarily lowering blood pressure.

Mental health benefits include stress reduction, improved mood, and better sleep quality. The heat exposure triggers the release of endorphins and other neurotransmitters that promote relaxation and well-being. Muscle recovery and pain management represent another compelling benefit, particularly for athletes and those with chronic pain conditions. The increased blood flow delivers nutrients to damaged tissues while helping remove metabolic waste products. For maximum recovery benefits, consider combining your Auroom sauna with contrast therapy protocols.

Creating Your Complete Wellness Space

An Auroom sauna can serve as the centerpiece of a comprehensive home wellness space. Alternating between hot sauna sessions and cold exposure stimulates circulation, reduces inflammation, and may boost immune function. Many Auroom customers install their outdoor saunas near a cold plunge to create convenient hot-cold circuits — read our cold plunge vs ice bath guide to explore your options.

Every Auroom sauna comes with a complete accessory set including a bucket and ladle, thermometer and hygrometer, and aroma set. For additional accessories or replacement items, browse our Auroom collection for compatible options.

Installation Considerations

Proper installation is critical for maximizing the lifespan and performance of your Auroom sauna. Indoor saunas require locations that can handle the heat and humidity generated during use — basements, garages, and dedicated wellness rooms with proper ventilation are ideal. Adequate vapor barrier installation prevents moisture migration into surrounding building materials.

Electrical requirements must be carefully addressed before installation. Most Auroom saunas require 240V electrical service with dedicated circuits appropriately sized for the chosen heater. Our sauna electricity cost guide covers circuit sizing, wire gauge, and GFCI protection in detail. Outdoor sauna placement should consider site preparation, drainage, access to electrical service, and visual integration with your landscape.

Maintenance and Care

Auroom saunas are designed for minimal maintenance, but following basic care guidelines will ensure decades of reliable service. After each use, leave the door slightly open to allow the interior to dry thoroughly, preventing moisture accumulation that could lead to mold or mildew growth. Periodic cleaning with mild, sauna-specific cleaners removes body oils and perspiration from bench surfaces — avoid harsh chemicals or abrasive cleaners that could damage the wood finish.

For outdoor saunas, occasional application of appropriate exterior wood treatments helps maintain appearance and weather resistance. Inspect your sauna heater regularly according to manufacturer guidelines, and check sauna stones periodically for deterioration. Replace stones when they show signs of significant crumbling or breakdown.

Frequently Asked Questions

Do Auroom saunas come with a heater?

How long does it take to assemble an Auroom indoor sauna kit?
Most indoor kits can be assembled by two people in 4 to 6 hours. Every sauna is fully assembled at the factory before shipping to verify all parts fit correctly, and detailed instructions are included.

What electrical requirements do Auroom saunas have?
Most models require a dedicated 240V circuit. The exact amperage depends on your heater selection — a 6kW heater typically needs a 30-amp circuit, while a 9kW heater requires 40 amps. Read our sauna electricity cost guide for complete details.

Can I use HSA or FSA funds to buy an Auroom sauna?
Every invoice at Sauna Republic includes a "Pay with Truemed" option. You click it, complete Truemed's health assessment, and if Truemed approves, the transaction completes with HSA/FSA funds. Truemed determines eligibility per customer — we don't make that call. Learn more.

What's the difference between Aspen and Thermo-Aspen finishes?

How does Auroom compare to other indoor sauna brands?
Auroom is widely considered one of the benchmarks for indoor sauna kits due to Thermory timber quality, Estonian craftsmanship, and design range.
