Transform Your Denver Home Into a Private Retreat

Dreaming of the comfort and calm of a luxury spa without leaving your house? At Denver Custom Saunas, we design and install fully customized indoor saunas that integrate beautifully into your home. From primary suites and basements to spare bedrooms and even master bathrooms, we turn underused areas into private wellness escapes. Every sauna is built around your lifestyle, prioritizing comfort, long-term health benefits, and lasting performance.

What You’ll Get With a Custom Indoor Sauna

Every sauna we build is 100% custom-designed—never a generic kit. Our process includes precise space planning, detailed design, and professional installation. We work with high-quality woods such as cedar, hemlock, and spruce, paired with your choice of advanced heating systems: electric, infrared, steam, or hybrid.

Want to take your sauna to the next level? Choose upgrades like LED chromotherapy lighting, integrated sound systems, or ergonomic seating to create a true spa-like retreat inside your Denver home.

Frequently Asked Questions

How long does it take to install an indoor sauna in Denver?

Most projects take 3–10 days after materials arrive, depending on size and complexity. We start with a consultation, then prepare a 3D design and handle all logistics. Our Denver installation team works carefully and efficiently, minimizing disruption to your household. Once complete, we’ll walk you through operation, cleaning, and maintenance so you feel confident using your sauna every day.

What’s the best place in a Denver home for an indoor sauna?

Indoor saunas can fit into several areas, each with unique advantages. Finished basements are great for privacy and stable temperatures, while master bathrooms offer the ultimate convenience just steps from your shower. Spare bedrooms, walk-in closets, and home gyms are also excellent choices. At Denver Custom Saunas, we review your home’s layout, ventilation, and goals to recommend the safest and most comfortable location for long-term use.

Do indoor saunas need special electrical or ventilation work?

Yes. Proper setup ensures both safety and performance. Most electric and infrared saunas need a dedicated electrical circuit with GFCI protection. We’ll coordinate with your licensed Denver electrician—or connect you with one of our trusted partners—to confirm everything meets code. Ventilation is also essential to control humidity and allow proper drying between uses. We include all of this in the planning phase to make sure your sauna operates efficiently without affecting the rest of your home.

What are the typical dimensions for a custom indoor sauna?

Indoor saunas can be built to fit nearly any space, but common sizes are chosen for comfort and energy efficiency. At Denver Custom Saunas, we design everything from compact 4’ x 4’ units to family-sized 8’ x 10’ rooms.

Ceiling height is also key—7 feet is ideal for even heat and comfortable headroom. Ceilings higher than 8 feet make it harder to regulate temperature with traditional heaters.

Popular layouts include:

* 4’ x 6’ – compact, fits 1–2 people with corner seating

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

* 5’ x 7’ – great for small families or multi-use rooms

We’ve also installed saunas in unique Denver spaces, including attic conversions, angled-roof rooms, and narrow alcoves in historic homes. During your consultation, we’ll recommend the best fit for your home and goals.

Can I install a custom indoor sauna in my basement?

Absolutely. Basements are one of the most popular sauna locations in Denver because they’re private, naturally cooler, and often underutilized. We’ve transformed basements across the metro—Lakewood to Aurora—into beautiful wellness retreats. Whether you want a dedicated sauna room or one integrated into a home gym, we’ll ensure proper insulation, ventilation, and heater placement. Electric, infrared, and steam systems can all be adapted for basement installations.

Other popular spots for indoor saunas in Denver homes include luxury master bathrooms in Cherry Creek, spare bedrooms in Highlands Ranch, and converted garage studios in Boulder. Whatever your layout, we’ll help you find the perfect fit.
