How My Fitness Outlet helps you add a sauna that pays for itself

We work with gyms, hotels, spas, multifamily developers, and corporate wellness teams to spec, source, and install commercial-grade saunas that actually generate revenue. The calculator above gives you a planning estimate. Our team gives you the full layout, electrical requirements, freight breakdown, and quote — usually within one business day.

What we do

End-to-end commercial sauna projects

We carry traditional and infrared saunas from authorized brands like Golden Designs, sized for one-person amenity rooms through multi-occupant spa builds. You get a single point of contact across selection, electrical specs, freight, and post-install support — no juggling manufacturers.

Who we work with

Operators who treat wellness as an amenity, not a checkbox

Boutique gyms upcharging for sauna access. Hotels and resorts adding a spa floor. Multifamily developers competing on resident retention. Corporate campuses building out wellness rooms. If sauna ROI is part of the business case, we can model it with you.

How we help you win

Realistic numbers, fast quotes, accountable install

Most sauna vendors won't talk economics. We will. We'll pressure-test your utilization assumptions, energy costs, and pricing model before you commit, then handle freight, install coordination, and warranty so the project actually closes.

Frequently asked questions

How long does it take for a commercial sauna to pay for itself?

For most fitness facilities, a commercial sauna pays back in 6 to 24 months. The exact timeline depends on how you monetize it — a $15/month membership upcharge with 40 to 50 paying members typically covers a $6,000–$10,000 infrared sauna inside a year. Pay-per-use models (common in hotels and spas) tend to take 12 to 30 months. Use the calculator above to model your specific inputs.

What's the difference between infrared and traditional saunas for ROI?

Infrared saunas draw about 1.5 to 2 kW and heat up in 10 to 15 minutes, making them roughly 3x cheaper to operate than traditional saunas, which pull 6 to 9 kW and need a 30+ minute warm-up. Infrared also requires less ventilation and lower installation cost, which is why amenity rooms in gyms, multifamily, and corporate wellness usually go infrared. Traditional saunas remain the standard in spas and full-service wellness centers where members expect higher temperatures and steam (löyly).

How much does it cost to add a commercial sauna?

Budget $5,000 to $9,000 for a quality 2 to 4-person commercial infrared sauna, plus $500 to $1,500 for installation and electrical depending on your panel capacity and room location. Traditional saunas run $6,000 to $15,000 plus a higher install cost because they need a dedicated 240V circuit, proper ventilation, and a moisture-rated room. Larger multi-occupant builds for spas can exceed $25,000.

What does it cost to operate a commercial sauna each month?

Operating cost is mostly electricity plus light maintenance. A 2 kW infrared sauna running six 35-minute sessions a day at $0.15/kWh costs roughly $30 to $45 per month in energy. Traditional saunas at 6 kW under the same use pattern cost $90 to $130 per month. Add about $30 to $50 per sauna per month for routine maintenance, wood treatment, and cleaning supplies.

Can we charge an upcharge for sauna access at our gym?

Yes, and it's the most common monetization model. Most gyms add a $10 to $25 monthly upcharge to a "wellness" or "premium" tier that includes sauna access. Penetration of 20 to 35% of your active member base is typical once you market it for a quarter. Some operators bundle sauna with other recovery amenities (cold plunge, massage chairs, red light) to justify a higher upcharge.

What about hotels and multifamily — do those numbers work?

Hotels and resorts typically monetize sauna access through pay-per-use spa fees ($10 to $25 per session) or as a value-add baked into resort fees. Multifamily projects rarely charge per-use, but a sauna in the amenity package is consistently cited as a retention and rent-premium driver. The ROI case for multifamily is closer to a capital expense that lifts NOI through reduced turnover and higher achievable rent, rather than a direct fee revenue model.

How accurate is this calculator?

The calculator is a planning tool, not a quote. It uses standard assumptions for energy draw, monthly hours, and revenue mix. Real-world variance comes from local electricity rates, member utilization, your specific sauna model's wattage, and how aggressively you market the amenity. For an itemized proposal with your exact equipment, freight, and install costs, request a quote.

Do you handle installation?

We coordinate freight and provide installation guidance, electrical specs, and manufacturer documentation. For most commercial saunas a licensed electrician handles the hookup. For larger custom or multi-occupant builds, we'll connect you with vetted regional install partners. Contact our commercial team for details on your specific project.
