Installing an outdoor sauna is an investment that should bring enjoyment for many years. Before choosing the right model, it’s worth considering one important question – where should you place your sauna, and how should you prepare the installation site? Choosing the right location, building a solid foundation and planning the electrical connection will make installation easier and ensure reliable operation for years to come.
A well-designed sauna is more than just a building. It becomes a natural part of your garden and a place you’ll look forward to visiting after work, after exercise or on cold winter evenings.
In this guide, you’ll find everything you should know before ordering an outdoor sauna.
1. Choose the Right Location – It’s About More Than Just Space
The location of your sauna will influence every future sauna session. It’s not just about where the sauna physically fits, but where you’ll feel comfortable, enjoy privacy and truly relax.
Prioritize Privacy
Sauna bathing is about slowing down, relaxing and enjoying uninterrupted time alone or with your family. Choose a location where you can unwind without being disturbed by neighbours or nearby activity.
A quiet corner of the garden, naturally screened by trees, hedges or the house itself, is often the best choice. If your garden is more open, privacy can easily be created with landscaping or modern privacy screens.
A carefully chosen location allows your sauna to become exactly what it should be—a place where you can disconnect from everyday life and simply relax.
How Far Should the Sauna Be from the House?
It may be tempting to place your sauna at the far end of the garden to enjoy the best possible view. However, think about everyday use as well.
During winter you’ll walk between the house and the sauna several times in one evening. If the distance is too long, it may become less practical and comfortable.
On the other hand, placing the sauna too close to your main terrace or outdoor seating area may reduce the sense of peace and privacy.
The ideal location strikes a balance between convenience, privacy and atmosphere.
Make the Most of the View
If you choose a sauna with a panoramic glass front, think carefully about its orientation. Looking out onto a garden, forest or natural landscape can significantly enhance the entire sauna experience.
A view of a fence, neighbouring building or technical area is unlikely to provide the same feeling of relaxation.
2. Plan Your Cooling Area from the Beginning
A traditional Finnish sauna experience doesn’t end when you step outside. Cooling down is an essential part of the ritual, and alternating between heat and cold is one of the main reasons people love sauna bathing.
When planning your outdoor sauna, leave enough space for:
- a cold plunge tub,
- an outdoor shower,
- a natural swimming pond,
- a swimming pool,
- or simply an open area where you can cool down outdoors.
Keeping the cooling area close to the sauna makes the entire experience more enjoyable and convenient.
3. Preparing the Foundation
An outdoor sauna requires a stable, level and durable foundation to ensure long-term performance and structural stability.
The most common options include:
Reinforced Concrete Slab
The most reliable solution for almost every outdoor sauna. A reinforced concrete slab, typically 100–150 mm thick, is recommended depending on local conditions and the manufacturer’s recommendations.
Concrete or Paving Stones
A suitable solution when installed on a properly prepared and compacted base with sufficient load-bearing capacity.
Timber Deck
A visually attractive option, provided the deck has been engineered to support the full weight of the sauna.
Gravel Base
Suitable only for certain lightweight sauna models and where recommended by the manufacturer.
Important: An outdoor sauna should never be installed directly on grass or soft ground. Constant moisture may affect the lower part of the structure and reduce its lifespan.
4. Prepare the Electrical Connection
Most modern outdoor saunas are equipped with electric sauna heaters.
Before installation, ensure the correct electrical supply has been prepared according to the heater’s power requirements. Electrical specifications vary depending on the sauna model and local regulations, so installation should always be carried out by a qualified electrician.
If you also plan to install outdoor lighting, an audio system or other accessories, it’s worth preparing the necessary electrical connections at the same time.
5. Design the Entire Wellness Area
The best outdoor saunas are not standalone buildings. They become part of a thoughtfully designed outdoor wellness space.
When planning the area, consider including:
- a comfortable path leading to the sauna,
- a relaxation area,
- loungers or outdoor seating,
- ambient lighting,
- a place for towels and accessories,
- safe access during winter,
- firewood storage if using a wood-burning heater.
These details make a significant difference to the overall comfort and enjoyment of your sauna.
6. Check Local Building Regulations
Building regulations for outdoor structures vary between countries and regions.
Before installation, check local requirements regarding building permits, minimum distances from property boundaries and any planning regulations that may apply.
Common Mistakes When Planning an Outdoor Sauna
Most installation problems don’t occur during installation itself—they begin during the planning stage.
Avoid these common mistakes:
- choosing a location without sufficient privacy,
- placing the sauna too far from the house,
- forgetting to plan the cooling area,
- underestimating the importance of a proper foundation,
- not preparing the electrical connection in advance,
- designing the surrounding space only after the sauna has been installed.
Frequently Asked Questions
How far should an outdoor sauna be from the house?
Ideally, it should be close enough for convenient year-round access while still providing sufficient privacy and a peaceful atmosphere.
Do I need a concrete foundation?
In most cases, yes. A reinforced concrete slab provides the most stable and durable foundation. Some sauna models can also be installed on other suitable load-bearing surfaces, depending on the manufacturer’s recommendations.
Can an outdoor sauna be installed on a timber deck?
Yes, provided the deck has been structurally designed to support the weight of the sauna.
What electrical connection is required?
This depends on the heater output and the specific sauna model. Always follow the manufacturer’s specifications and consult a qualified electrician.
Do I need planning permission?
Requirements vary depending on your country and local regulations. Always check the applicable rules before installation.
Is a sauna with a glass front a good choice?
If you have a beautiful view and enough privacy, a panoramic glass front can greatly enhance your sauna experience. If your sauna is close to neighbouring properties or a boundary fence, a more enclosed design may be the better option.
