Outdoor Saunas – Premium Exterior Saunas for Home & Garden
An outdoor sauna is one of the most authentic and rewarding ways to enjoy true wellness at home. Installed in a garden, backyard, or outdoor living area, an exterior sauna brings the traditional sauna experience out of the house and into nature — offering privacy, space, and year-round usability.
Outdoor saunas are increasingly popular across the country as homeowners look for long-term wellness solutions that enhance both lifestyle and property value. Whether you are searching for a compact sauna outside for personal use or a larger outdoor sauna for family and guests, modern exterior saunas are designed to perform reliably in the British climate while delivering exceptional comfort.
This guide explains what an outdoor sauna is, the different types available, how to choose the right model, and what to consider when looking for outdoor saunas for sale. We supply and deliver outdoor saunas across the UK, with direct delivery from the TimberIN manufacturer.

Getting started
Heating & sauna styles
1. Why Choose an Outdoor Sauna?
Choosing to place your sauna outside is a decision rooted in tradition and practicality. In Finland, the birthplace of sauna culture, saunas were almost always separate structures.
The Connection to Nature
Stepping out of a heated sauna into the fresh air of a garden is a vital part of the “thermal cycle.” The contrast between the intense, dry heat inside and the cool outdoor environment provides a sensory experience that indoor saunas cannot replicate. Whether it is the sound of rain on the roof or the view of a snowy garden through a panoramic window, being outdoors enhances the meditative quality of the session.
Health and Wellness Benefits
- Detoxification: Profuse sweating helps the body flush out toxins and impurities through the pores.
- Cardiovascular Health: The heat increases heart rate and improves circulation, mimicking the effects of light exercise.
- Stress Relief: Regular sauna use is proven to lower cortisol levels and promote the production of endorphins, leading to better sleep and improved mental clarity.
- Muscle Recovery: Heat therapy is excellent for soothing sore muscles and joints after physical activity.
Property Value and Aesthetics
A well-designed outdoor sauna, such as a barrel or pod model, serves as a striking architectural feature in a garden. It transforms an underutilized space into a luxury wellness zone, which is a significant selling point for modern property markets.
2. Exploring Outdoor Sauna Styles
The TimberIN® collection offers a variety of layouts and styles to suit different spatial requirements and aesthetic preferences.
Traditional & Finnish Outdoor Saunas
These models focus on the authentic Nordic experience. They typically feature rectangular or square layouts with tiered benches, allowing users to choose their heat intensity by sitting higher or lower.
- Design: Authentic Finnish-style saunas use dry heat and premium timber to create a true Nordic atmosphere.
- Ideal for: Large families or those who want a classic “cabin” look in their backyard.
Outdoor Barrel Saunas
The barrel sauna is an iconic design that is as functional as it is beautiful. Its circular shape is not just for show; it is highly efficient for air circulation.
- Efficiency: Because there are no “dead corners” (like those found in rectangular saunas), the heat circulates more evenly, leading to faster heat-up times and lower energy consumption.
- Compact Nature: Ideal for gardens and compact outdoor spaces where a smaller footprint is required.
Pod and Igloo Saunas
For those who want a more modern or “fairytale” aesthetic, the Pod (and its variants like the Igloo) offers a unique arched roofline.
- Atmosphere: The curved walls create a cozy, intimate environment.
- Practicality: The sloped roof is excellent for regions with high rainfall or snow, as it prevents accumulation on the top of the structure.
1–2 Person / Compact Outdoor Saunas
Wellness shouldn’t be limited by space. Compact models are designed specifically for couples or solo users.
- Versatility: These are perfect for small gardens, patios, and even terraces.
- Rapid Heating: Due to the small internal volume, these units reach operating temperature very quickly.
Mobile Outdoor Saunas
A unique offering for those who need flexibility or are looking for business opportunities.
- Transportability: These are fully transportable saunas built on trailers.
- Use Cases: They are perfect for events, rentals, glamping sites, or homeowners who may want to move the unit between different locations.
3. Heating Your Sanctuary: Wood Fired vs. Electric
The heating method is the “heart” of your sauna experience. TimberIN provides options for both traditionalists and those seeking modern convenience.
Wood Fired Outdoor Saunas
For many, a sauna isn’t a “real” sauna without the crackle of a wood fire and the faint scent of smoke.
- Atmosphere: Delivers intense, natural heat and an authentic off-grid atmosphere.
- Off-Grid Living: Since they require no electricity, they are the best option for remote locations, cabins, or large gardens where running power lines would be difficult or expensive.
- The Ritual: The process of chopping wood and tending the fire becomes a part of the relaxation ritual itself.
Electric Outdoor Saunas
Electric heaters are the gold standard for ease of use and precision.
- Convenience: With a simple switch or even a smartphone app, you can pre-heat your sauna while you finish dinner or return from a run.
- Control: Electric heaters allow for precise temperature settings and often include timers and safety shut-off features.
- Urban Environments: These are often the preferred choice for suburban gardens where neighbors might be sensitive to wood smoke.
4. Materials and Construction
The durability and performance of an outdoor sauna depend heavily on the quality of the timber and construction techniques used.
Premium Timber Options
TimberIN utilizes woods that are naturally resistant to decay and can withstand the expansion and contraction caused by extreme temperature changes.
- Thermowood: This wood undergoes a heat-treatment process that removes moisture and resins. The result is a highly stable, rot-resistant timber with a beautiful dark hue that is perfect for the fluctuating climates of the UK and Ireland.
- Spruce: A traditional choice, Spruce is durable and offers the classic light-colored sauna look.
- Cedar: Known for its incredible aromatic properties and natural resistance to insects and moisture.
Insulation and Glass
While many traditional saunas are “single-wall” structures, premium outdoor models often incorporate insulated roofs or double-glazed windows to retain heat more effectively.
- Panoramic Windows: Modern designs often feature large glass fronts or half-moon windows. TimberIN ensures these use tempered safety glass to handle high temperatures and provide expansive views of your garden.
5. Combined Wellness: Sauna & Hot Tub Combo Sets
For the ultimate luxury experience, many homeowners opt for a Sauna & Hot Tub Combo Set.
- Contrast Therapy: Combining the dry heat of a sauna with the hydrotherapy of a hot tub is ideal for recovery and relaxation.
- Social Hub: These sets create a complete wellness center in your backyard, perfect for entertaining guests or family gatherings.
6. Practical Considerations for Installation
Choosing the Right Location
Your sauna should be placed in a spot that offers a balance of privacy and accessibility. Consider the “view” from the sauna window—staring at a fence is less relaxing than looking at a garden or natural landscape.
Foundation and Base Preparation
A stable foundation is critical. Because saunas are heavy (especially when occupied by several people), they should be placed on a level surface such as:
- Concrete Pad: The most durable and permanent option.
- Paving Slabs: A good middle-ground that allows for drainage.
- Heavy-Duty Decking: Ensure the joists are reinforced to handle the weight.
Power Requirements
If you choose an electric heater, you will need a certified electrician to install a dedicated power line. Depending on the heater’s kilowatt (kW) rating, this may require a 230V single-phase or 400V three-phase connection.
Planning Permission
In the UK and Ireland, outdoor saunas are generally considered “outbuildings” and often fall under “Permitted Development.” However, there are rules regarding height and proximity to boundaries. It is always recommended to check with your local planning authority before installation.

8. Frequently Asked Questions
What is the best type of wood for an outdoor sauna? Traditional Finnish saunas and barrel models perform best when built with Thermowood or Northern Spruce, as these materials offer the high thermal resistance needed for the British and Irish climates.
Do I need a foundation for my garden sauna? Yes, a level and stable base—such as a concrete pad, paved area, or heavy-duty decking—is essential to prevent the structure from shifting and to ensure proper drainage.
How long does it take for an outdoor sauna to heat up? Heating times vary by model; iconic barrel saunas offer the fastest heat-up times due to efficient air circulation, typically reaching optimal temperatures in 30–60 minutes depending on the heater type.
