Indoor Saunas

Indoor saunas can be installed in a variety of places depending on your lifestyle and space. Finished basements allow for larger builds and natural temperature control, while master bathrooms provide convenience right next to your shower. Spare bedrooms, converted walk-in closets, and home gyms are also excellent options. At Stamford Custom Saunas, our team reviews your floor plan, ventilation, and goals to help you choose the safest and most comfortable location.

Yes. Basements are one of the most popular choices in Connecticut homes because they offer privacy, cooler starting temperatures, and plenty of underutilized space. We’ve transformed basements across Stamford, Norwalk, and Greenwich into wellness retreats. Whether you’d like a standalone sauna room or one built into a home gym or media area, we ensure proper insulation, moisture protection, and safe heater installation.

Other common indoor sauna locations in Fairfield County include bathrooms in Darien, spare rooms in New Canaan, and garage studios in Westport. Whatever your layout, we’ll help you maximize the space.

Most residential sauna installations are completed within 3–10 days once materials are delivered. Our process starts with a consultation and detailed design plan, then we handle all site prep, delivery, and installation. Our Stamford sauna installers work efficiently with minimal disruption, and once finished, we provide a walkthrough so you understand how to use, clean, and maintain your sauna with confidence.

Indoor saunas can be designed to fit nearly any footprint, but common sizes include:

* 4’ x 6’ – fits 1–2 people, ideal for small condos or bathrooms.

* 5’ x 7’ – fits small families, great for spare rooms.

* 6’ x 8’ – seats 3–4 people with tiered benches.

* 8’ x 10’ – large family-sized saunas for basements or gyms.

Ceiling height is also important. Around 7 feet is ideal for heat consistency and comfort. Higher ceilings (over 8 feet) can make it harder to regulate temperatures, especially with traditional stone heaters.

We’ve even installed saunas in unique Stamford spaces such as attic conversions, alcoves in historic homes, and angled-roof additions. During your consultation, we’ll take detailed measurements and recommend the best fit.

Yes. Most saunas require a dedicated electrical circuit for safety and performance. Infrared and electric models often need GFCI protection. Our sauna contractors work with your licensed Stamford electrician—or connect you with a trusted partner—to ensure your setup meets local code.

Ventilation is equally important to control humidity and allow the sauna to dry properly between uses. We factor this into the design from the start, so your sauna operates safely and efficiently without affecting the rest of your home.
