What is the outdoor sauna?

Saunas, dedicated spaces for relaxation and rejuvenation through heat therapy, exist in both indoor and outdoor variations, each sharing core principles but featuring distinctive characteristics.

While both indoor and outdoor saunas harness heat sources, sauna stones, and water to generate steam, a notable divergence lies in the prevalence of infrared saunas emitting dry heat, which are more commonly found indoors but increasingly available for outdoor use.

Crafted to withstand the vagaries of weather and temperature fluctuations, outdoor saunas employ specialized materials, setting them apart from their indoor counterparts. Beyond materials, several factors distinguish outdoor saunas:

  1. Diverse Designs: Unlike the standard box or cube shape prevalent in indoor saunas, outdoor saunas offer a broader spectrum of design options.
  2. Ventilation Ease: Outdoor saunas are generally easier to ventilate compared to their indoor counterparts. However, the installation process may be more intricate, necessitating adherence to local building codes, especially concerning wiring and chimney specifications.
  3. Size Disparities: Indoor saunas typically boast a more compact design, while outdoor saunas come in a range of sizes tailored to open-air settings.

Understanding these nuances is crucial when considering the installation and utilization of outdoor saunas, ensuring they harmonize with both personal preferences and the environment they inhabit.

The exact inception of outdoor saunas remains shrouded in mystery, with scholars suggesting a plausible commencement around 2,000 BCE in the northern reaches of Europe.

The earliest renditions of saunas likely resembled man-made caves, ingeniously sealed with water-resistant animal hides to thwart the intrusion of wind, snow, and rain.

Delving into the annals of ancient sauna history reveals fascinating insights:

  1. Health and Hygiene: Sauna rooms, with their enduring warmth and the sanitizing effects of smoke, became instrumental in enhancing the well-being and cleanliness of their occupants, contributing significantly to daily survival.
  2. Versatility of Use: Saunas from antiquity served multifaceted roles, functioning not only as spaces for relaxation but also doubling as birthing rooms, washrooms, kitchens, communal areas for festivities, and even makeshift mortuaries for preparing the deceased for burial.
  3. Adaptability as Dwellings: Beyond their utilitarian purposes, these saunas often doubled as homes due to their ability to retain warmth, increasing the likelihood of survival during harsh winter months.
  4. Sacred and Healing Significance: The therapeutic attributes of these ancient saunas elevated them to the status of sacred spaces, with some cultures attributing healing powers to sauna spirits. This belief in the magical properties of saunas persists in certain circles even today.

Piecing together the historical tapestry of outdoor saunas not only unveils their pragmatic origins but also underscores their cultural and spiritual significance across diverse civilizations.

Distinguishing factors among backyard saunas encompass three key elements:

  1. Heat Source
  2. Shape
  3. Size


Saunas generate heat through either traditional or “non-traditional” means, the latter involving infrared heaters. A closer look at these heat sources illuminates their workings:


Traditional saunas, also known as “wet saunas” or “steam saunas,” closely emulate the ancient sauna concept. Here’s how this type operates:

  1. Place sauna stones atop the heater for warming.
  2. Once hot, sprinkle water on the stones to create steam.
  3. The steam circulates, elevating the room temperature and inducing perspiration.

Many outdoor sauna enthusiasts favor the traditional option for its authentic ambiance. Modern iterations of traditional saunas offer dual heating methods: a wood-burning heater for an authentic experience or an electric heater.

Saunas equipped with a wood-burning stove utilize firewood to heat the rocks, enveloping users in a fragrant atmosphere. This sauna type requires no wiring but mandates the installation of a chimney.

In saunas with electric heaters, the rocks are heated using electricity. This is the standard choice in Almost Heaven Saunas, offering faster heating times and temperature control.


Infrared saunas adopt a more targeted, contemporary approach to heat therapy. Instead of heating the entire room like traditional saunas, infrared saunas generate radiant heat through infrared heaters. Though the room temperature may not be as high, the body absorbs the radiant heat, prompting perspiration. Infrared saunas are proven to be seven times more effective than traditional saunas in detoxifying the body.


Whether you seek a quaint, rustic sauna to infuse your yard with a cottage-like charm or a modern, stylish retreat, a myriad of distinctive styles awaits your selection for your new sauna.


The barrel sauna stands out with its exceptional circular design, delivering both aesthetics and functionality:

  • Natural water shedding enhances durability, ensuring longevity even in adverse weather conditions.
  • While suitable for indoor use, barrel saunas truly shine as outdoor installations.
  • Their rounded shape facilitates quicker heating times and superior air circulation.
  • For outdoor use, the barrel sauna arrives ready for installation, eliminating the need for additional insulation.


A newcomer to the sauna scene, the pod sauna introduces innovation and elegance:

  • Showcasing an inventive rain-drop shape, the pod sauna adds a modern touch to your space.
  • Its taller design provides users with added headspace, enhancing overall comfort.
  • Optional chic overhang cove offers shelter for the entrance, adding a stylish element.
  • Featuring a robust triple-layer roof, the pod sauna requires no extra insulation during installation.


Similar to the barrel sauna but with vertical walls, the cube sauna offers expanded interior space:

  • Distinguished by vertical walls, the cube sauna maximizes interior roominess.
  • Outdoor oval saunas boast an exceptionally wide front, setting them apart in design.
  • Outdoor saunas integrated with a hot tub combine modernity with relaxation.
  • Vertical up right built saunas designed for 2-4 persons.
  • Modern saunas

Explore these diverse sauna styles, each offering a unique blend of aesthetics and functionality, ensuring your new sauna becomes a personalized oasis in your outdoor environment.


When deliberating between indoor and outdoor saunas, both options offer an array of health benefits, such as:

  1. Reduced blood pressure.
  2. Alleviated lung inflammation.
  3. Enhanced immune system against common colds and flu.
  4. Elimination of harmful toxins.
  5. Support for weight loss and management.
  6. Promotion of clearer, blemish-free skin.
  7. Stress relief and meditation opportunities.

While both indoor and outdoor saunas are commendable, opting for a garden sauna comes with distinct advantages:

  1. Space Optimization: Placing your sauna in the garden saves valuable indoor space, ensuring your living areas remain uncluttered.
  2. Aesthetic Appeal: An outdoor traditional sauna not only contributes to your well-being but also adds charm to your garden, potentially increasing your property’s value.
  3. Convenient Access: A strategically located sauna just outside your front door offers a quick retreat without the need to venture far from your property.
  4. Versatile Use: An outdoor sauna can double as a pool house, providing additional functionality. During winter, you can even enjoy quick dips in the pool between sauna sessions, making the most of your outdoor space.

In summary, the unique benefits of garden saunas make them an appealing choice, seamlessly blending wellness with aesthetics and practicality in your outdoor haven.



Maintaining the cleanliness of your garden sauna is crucial for a delightful and hygienic experience. Follow these steps before each session:

  1. Foot Cleaning: Wipe your feet before entering the sauna to minimize dirt and sweat accumulation, reducing the risk of mold growth inside.
  2. Pre-Sauna Shower: Take a quick shower before your sauna session to minimize the transfer of dirt, sweat, and grime onto benches and floors.


Regular cleaning ensures a pristine environment within your garden sauna. Adopt these practices:

  1. Routine Cleaning: Vacuum or sweep your sauna regularly, complemented by deeper cleaning at least once a month. Always turn off the sauna before cleaning to avoid exposure to higher temperatures.
  2. Chemical-Free Approach: Use chemical-free products and warm water for a safe and effective cleaning process. A mixture of baking soda and water is a natural and efficient cleaning agent. For stubborn stains, employ fine-grit sandpaper.
  3. Pressure Washing: If needed, pressure wash the sauna’s interior with a wide-patterned nozzle set to low pressure.


Preserving the integrity of the wooden interior is essential for long-lasting beauty. Consider the following:

  1. Water Quality: Avoid hard water to prevent lime buildup caused by magnesium and calcium salts. Use sanding discs for lime removal.
  2. Avoid Sealants: Refrain from using protectants or sealants inside the sauna, as heat can release toxic chemicals.
  3. Towel Usage: Always use towels during sessions, washing them promptly after each use.
  4. Regular Wiping: Wipe the wooden interior regularly with warm water and a soft cloth to maintain its appearance.
  5. Wood Touch-Ups: If the lumber warranty has expired and the wood appears faded, sand down those areas for a refreshed look.


Extend your garden sauna’s life by tending to its exterior with care:

  1. Wood-Penetrating Oil: Treat the outside with a wood-penetrating oil for protection.
  2. Pressure Washing: For a thorough cleanse, use a low-pressure setting on a pressure washer.
  3. UV-Inhibiting Stain: If staining the exterior, choose a product with a UV inhibitor to shield the wood from sunlight.
