Indoor Saunas

Bring a Private Wellness Retreat Into Your Chicago Home

Imagine stepping into the warmth and calm of a luxury spa without leaving your house. At Chicago Custom Saunas, we design and install fully customized indoor saunas that integrate seamlessly into your home’s layout and style. From master bathrooms and finished basements to spare bedrooms and even converted closets, our team transforms unused areas into wellness retreats designed for everyday relaxation. Each sauna is tailored to your lifestyle, built for comfort, long-term health, and reliable performance.

What You’ll Get With a Custom Indoor Sauna

Every sauna we build is unique—never a prefabricated, one-size-fits-all kit. Our process includes space planning, 3D design, and expert installation. We work with premium woods such as cedar, hemlock, and spruce, paired with advanced heating options including electric, infrared, steam, or hybrid systems. Looking for upgrades? Choose from LED accent lighting, built-in audio systems, glass doors, or ergonomic tiered seating to create a spa-level experience inside your Chicago home.

Frequently Asked Questions

What’s the best room in a Chicago home for an indoor sauna?

Indoor saunas can be installed in many places depending on your layout. Basements are popular because they provide privacy and stable temperatures. Master bathrooms allow for spa-like convenience near showers and tubs. Spare bedrooms, walk-in closets, and home gyms are also excellent choices. At Chicago Custom Saunas, we’ll review your floor plan, ventilation options, and lifestyle goals to recommend the best location.

Can I put a sauna in my basement?

Yes. Basements are one of the top choices for Chicago homeowners since they’re naturally cooler and often underused. We’ve converted basements in areas from Lincoln Park to Naperville into stunning private spas. Whether you want a stand-alone sauna room or one integrated into a gym or entertainment space, we’ll handle insulation, ventilation, and heater placement. Infrared, steam, and electric systems can all be adapted to basements.

Other popular placements in Chicagoland include master bathrooms in North Shore homes, spare bedrooms in Hyde Park, and converted attic spaces in Oak Park. Whatever your property type, we’ll find the best fit.

How long does installation take for an indoor sauna in Chicago?

Most projects take 3–10 days after materials arrive. Our process begins with a design consultation and detailed planning. We coordinate material delivery, electrical preparation, and all finishing touches. Our installers work cleanly and efficiently, minimizing disruption to your home. When complete, we provide a walkthrough to explain sauna operation, cleaning, and maintenance so you’re confident using it daily.

What sizes are common for custom indoor saunas?

We can design saunas for almost any available space, but certain sizes are popular:

* 4’ x 6’ for 1–2 people with a corner bench

* 6’ x 8’ for 3–4 people with tiered seating

* 8’ x 10’ for larger families or multipurpose wellness rooms

Ceiling height is just as important—7 feet is ideal to maintain even heat while leaving comfortable headroom. Taller ceilings (over 8 feet) can reduce heating efficiency, especially with traditional systems.

We’ve installed saunas in unique Chicago spaces such as loft conversions, angled-roof attics, and narrow alcoves in historic greystones. During your consultation, we’ll measure carefully and design the best fit for your goals.

Do indoor saunas need special electrical or ventilation?

Yes. Safe, efficient operation depends on proper setup. Most electric and infrared saunas require a dedicated circuit with GFCI protection. We’ll coordinate with your licensed Chicago electrician—or connect you with one of our trusted partners—to ensure code compliance. Ventilation is equally important to control humidity and prevent moisture issues. Our sauna builders plan these systems in advance so your sauna operates flawlessly without affecting the rest of your home.
