Frequently Asked Questions

Which heating system should I choose for an outdoor sauna?

It depends on your preferences. Electric heaters are convenient and reliable for city homes. Wood-burning stoves provide a traditional, rustic feel and are popular in suburban or vacation properties. Infrared heaters are energy-efficient and run at lower air temperatures, while steam systems deliver a humid, spa-like atmosphere. We’ll walk you through the pros and cons of each and install the system that best suits your lifestyle.

How do indoor and outdoor saunas differ?

Indoor saunas are installed within the home—commonly in basements, bathrooms, or home gyms—and benefit from stable indoor temperatures and direct utility access. Outdoor saunas allow greater flexibility in size, layout, and design, and offer a unique connection to nature. Outdoor builds often include larger footprints, panoramic glass, or integration with pools and hot tubs. Each option offers distinct advantages depending on your space and lifestyle.

Where should an outdoor sauna be placed?

The best location depends on privacy, accessibility, and how you plan to use the sauna. Many Long Island homeowners choose backyard patios, garden areas, or poolside locations. Decks and private terraces are also popular options. When planning placement, we evaluate drainage, electrical access, wind exposure, and sightlines to ensure comfort and longevity. For example, a coastal property may benefit from added wind protection, while a backyard installation might include a covered walkway for all-season convenience.

Can outdoor saunas withstand Long Island weather?

Absolutely. Our outdoor saunas are built to handle Long Island’s coastal environment, including wind, moisture, temperature swings, and seasonal storms. We use weather-resistant woods such as cedar and thermally modified lumber, enhanced insulation, vented roofing, and sealed exterior finishes. Unlike low-quality prefabricated units that can deteriorate over time, our custom outdoor saunas are engineered for dependable, year-round use with proper care.

Do I need a concrete foundation for my outdoor sauna?

Yes, a solid base is essential for safety and longevity. Concrete pads are the most stable option, but alternatives like gravel beds or reinforced deck platforms can also work well. Gravel foundations provide excellent drainage during heavy Midwest rain, while deck platforms allow for seamless integration with your patio or rooftop. During consultation, our sauna builders evaluate your site and recommend the best foundation for stability and style.
