Indoor Saunas

Bring a Private Wellness Retreat Into Your Milwaukee Home

Imagine enjoying the soothing heat and calm of a spa without ever leaving your house. At Milwaukee Custom Saunas, we design and install fully custom indoor saunas that blend seamlessly with your home’s layout, architecture, and daily routine. From primary bathrooms and finished basements to spare rooms and converted closets, we transform underused spaces into personal wellness retreats built for daily relaxation, recovery, and long-term health. Every indoor sauna is designed around your lifestyle, with an emphasis on comfort, efficiency, and dependable performance.

What You’ll Get With a Custom Indoor Sauna

No two saunas we build are the same. We don’t rely on off-the-shelf kits—instead, every indoor sauna is thoughtfully planned and professionally built from the ground up. Our process includes detailed space planning, optional 3D design previews, and expert installation.

We work with premium sauna woods such as cedar, hemlock, and spruce, paired with advanced heating options including traditional electric heaters, infrared panels, steam systems, or hybrid configurations. Optional upgrades include LED mood lighting, integrated sound systems, glass doors, custom bench layouts, and ergonomic tiered seating—allowing you to create a true spa-quality experience inside your Milwaukee home.

Frequently Asked Questions

How long does indoor sauna installation take?

Once materials are delivered, most indoor sauna installations are completed within 3–10 days, depending on the complexity of the design. The process begins with a design consultation and detailed planning. We coordinate electrical preparation, material delivery, construction, and finishing details. Our installers work efficiently and respectfully, minimizing disruption. After installation, we provide a full walkthrough covering operation, cleaning, and daily use.

Do indoor saunas require special electrical or ventilation work?

Yes. Proper electrical and ventilation planning is essential for safe and efficient operation. Most electric and infrared saunas require a dedicated electrical circuit with appropriate protection. We’ll review your existing setup and coordinate with a licensed electrician if upgrades are needed. Ventilation is carefully planned to manage heat and humidity without impacting the rest of your home, ensuring your sauna performs reliably for years to come.

What sizes are common for custom indoor saunas?

We can design saunas for nearly any available space, but some common layouts include:

* 4’ x 6’ – Ideal for 1–2 people with compact bench seating

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

* 8’ x 10’ – Suitable for families or multi-purpose wellness rooms

Ceiling height is also important. A height of around 7 feet allows for even heat circulation and comfortable seating. Taller ceilings may reduce heating efficiency, especially with traditional electric systems. We’ve successfully designed saunas for unique Milwaukee spaces, including angled ceilings, narrow alcoves, and older homes with unconventional layouts.

Can a sauna be installed in a basement?

Yes. Basements are one of the most common locations for indoor saunas in Milwaukee homes. We regularly convert unused basement areas into private spa environments, whether as a stand-alone sauna room or integrated into a home gym or entertainment space. Our team manages insulation, ventilation, moisture control, and heater placement. Electric, infrared, and steam saunas can all be successfully installed in basement settings.

Other popular indoor sauna locations include primary bathrooms in suburban homes, spare bedrooms in city residences, and creatively repurposed spaces in older properties. No matter your home type, we’ll find a solution that fits.

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

Indoor saunas can be installed in a wide range of spaces depending on your home’s layout. Finished basements are a popular choice because they offer privacy and naturally cooler temperatures. Primary bathrooms create a spa-like experience with convenient access to showers, while spare bedrooms, walk-in closets, and home gyms also work well. During your consultation, we’ll evaluate your floor plan, ventilation options, and wellness goals to recommend the ideal location.
