Choosing the Right Sauna for Your Wellness Facility
05 June, 2026
For commercial spas, gyms and wellness facilities, choosing between an indoor or outdoor sauna is an important decision that can influence member satisfaction, customer retention and the overall appeal of the venue. Both options offer valuable benefits, but they also come with different operational considerations.
Indoor saunas remain the most common choice for commercial facilities. Their greatest advantage is accessibility. Members can move seamlessly from changing rooms, fitness areas or treatment spaces directly into the sauna, creating a convenient and comfortable experience regardless of the weather. This ease of access often encourages more frequent use, helping facilities maximise the value of their wellness offering.
Indoor installations also provide greater control over the environment. Temperature, ventilation and maintenance schedules can be managed more consistently, and staff can monitor usage more easily. For gyms and leisure centres operating year-round, indoor saunas can integrate naturally into existing facilities without requiring guests to leave the building.
However, indoor saunas require dedicated floor space, which can be at a premium in busy commercial environments. Installation may involve modifications to ventilation systems and utility connections, while ongoing maintenance must ensure that surrounding areas are protected from excess heat and humidity.
Outdoor saunas have become increasingly popular among premium spas, wellness retreats and fitness destinations looking to create a more distinctive customer experience. An outdoor sauna can serve as a standout feature, helping a facility differentiate itself from competitors. When positioned alongside gardens, relaxation areas or cold-water facilities, outdoor saunas can create an immersive wellness journey that appeals to modern consumers seeking experiences rather than simply amenities.
From a design perspective, outdoor saunas often offer greater flexibility in terms of size, layout and aesthetics. They can become a focal point for the property while preserving valuable indoor space for treatments, fitness equipment or additional member services.
The challenges are largely practical. Outdoor installations are exposed to changing weather conditions and may require more regular inspection and maintenance to preserve their appearance and performance. Guest accessibility can also be affected during periods of poor weather, particularly if the sauna is located some distance from the main facility. Initial installation costs may be higher due to groundwork, utility connections and site preparation requirements.
Ultimately, the decision comes down to the goals of the business. Indoor saunas offer convenience, efficiency and dependable year-round use, making them a strong choice for gyms and high-traffic wellness centres. Outdoor saunas provide a premium experience that can enhance brand positioning and create memorable customer experiences, particularly for spas and wellness destinations seeking to stand out in a competitive market.
When carefully planned and professionally maintained, both indoor and outdoor saunas can become valuable assets that contribute to customer satisfaction, loyalty and long-term business success.
