Frequently Asked Questions

Does an outdoor sauna require a permanent foundation?

Yes, a stable foundation is critical for safety and longevity. Concrete pads are the most common choice, but gravel bases and reinforced deck platforms are also effective. Gravel foundations provide excellent drainage during heavy rain and snowmelt, while deck-mounted saunas integrate smoothly with patios or elevated spaces. During your consultation, we assess your site and recommend the best foundation for both stability and design.

Where is the best location for an outdoor sauna?

Placement depends on your property layout and how you plan to use the sauna. Common locations include backyard patios, garden edges, poolside areas, and rooftop decks. In urban settings, rooftop saunas may require added wind protection, while suburban backyards often allow for covered walkways or privacy screening. We consider drainage, electrical access, privacy, and exposure to lakefront winds to determine the ideal placement for your outdoor sauna.

Which heating option is best for an outdoor sauna?

The right heater depends on how you plan to use your sauna. Electric heaters are popular for their convenience and consistent performance. Wood-burning stoves offer a classic sauna experience and are often chosen for larger yards or retreat-style properties. Infrared heaters operate efficiently at lower air temperatures, while steam systems create a humid, spa-like environment. We’ll explain the advantages of each option and install the system that best matches your lifestyle.

How do indoor and outdoor saunas differ?

Indoor saunas are integrated directly into your home—commonly in basements, bathrooms, or home gyms—offering easy access and stable indoor conditions. Outdoor saunas provide greater flexibility in size, layout, and design, along with a stronger connection to nature. Many outdoor installations feature larger footprints, panoramic glass, or integration with pools and hot tubs. Each outdoor sauna is reinforced to handle Wisconsin’s four-season climate.

Can outdoor saunas withstand Milwaukee winters?

Absolutely. Our outdoor saunas are engineered to perform through Milwaukee’s harsh winters and seasonal temperature swings. We use durable materials such as cedar and thermally modified wood, enhanced insulation, vented roofing systems, and weather-sealed finishes. Unlike mass-produced kits that can crack or warp over time, our custom builds are designed for reliable, year-round use. With routine care, your sauna will remain a dependable retreat for many years.
