How It Works
Five clear steps from first call to first sweat. You always know where your project stands.
Consultation
We visit your home or business, look at the space, talk through how you plan to use the sauna, and answer every question about materials, heat types, and budget before anything is drawn.
Design
You receive a custom design with layout, wood selection, heater specs, and a transparent quote. We refine it together until the plan matches exactly what you pictured.
Permitting
Our team handles the City of Jacksonville and St. Johns County permitting and coordinates any electrical work with licensed trades, so nothing falls on your plate.
Build
Licensed, insured craftsmen construct your sauna on a clear timeline. We keep the site clean, communicate daily, and never cut corners on insulation, wiring, or ventilation.
Walkthrough
We fire up the sauna together, walk you through heater operation and maintenance, and hand over care instructions. You start using it that same day.
Why Homeowners Choose Us
Built Right for Jacksonville
Custom Builds from Scratch
No cookie-cutter boxes. Every sauna is designed and built for your specific space, from oddly shaped bonus rooms in Avondale to sprawling pool decks in Queens Harbour. You choose the wood, the heater, the lighting, and the layout.
Designs Built for Jacksonville's Climate
Florida humidity, salt air near the Beaches, and summer storms all factor into how we build. We spec marine-conscious hardware, proper vapor barriers, and ventilation designed for a subtropical climate, not a Minnesota winter.
Licensed and Insured Contractors
Every build is completed by licensed, insured professionals who pull real permits and coordinate certified electricians. Your sauna is safe, code-compliant, and protected, which matters for insurance and resale alike.
End-to-End Project Management
One team owns your project from consultation through walkthrough. No chasing subcontractors, no gaps between trades. We schedule it, build it, inspect it, and stand behind it with a craftsmanship warranty.

What Clients Say
Jacksonville Homeowners on Their Builds
"They converted half of our garage in Ortega into a four-person cedar sauna. Quoted six weeks, finished in five. The ventilation work was clearly done by people who understand Florida humidity."
"We wanted an outdoor sauna near the pool for cold plunge contrast after runs. The crew handled the permit, the electrical, everything. My husband uses it more than the TV at this point."
"Practical, straightforward company. They talked me out of a bigger heater I did not need and the infrared room they built in our spare bedroom has worked flawlessly for eight months."

Yes, and it is one of our most requested builds. A pool-adjacent sauna creates a complete contrast therapy setup: heat in the sauna, then a cool-down in the pool. We position the structure for drainage, code setbacks, and storm exposure, and use weather-sealed materials suited to Florida's humidity and salt air.
We primarily build with Western Red Cedar and Canadian Hemlock for interiors because both resist moisture and stay comfortable at high temperatures. Steam rooms use porcelain, ceramic, or stone tile over a fully waterproofed substrate. Heaters, controls, and hardware are commercial-grade brands chosen for longevity in Florida conditions.
Most sauna installations in Jacksonville require an electrical permit, and outdoor structures may need a building permit depending on size and placement. We handle the entire permitting process with the City of Jacksonville or your county office as part of every project, so you never deal with paperwork.
A traditional sauna heats the air around you to 150 to 195 degrees using an electric or wood-fired heater, while an infrared sauna warms your body directly with light panels at a gentler 120 to 140 degrees. Traditional saunas deliver the classic intense heat and steam experience; infrared suits longer, lower-temperature recovery sessions. Many Jacksonville clients choose based on how they plan to use it, and some install both.
Yes. We design and build commercial saunas and steam rooms for gyms, spas, hotels, wellness studios, and recovery centers across Jacksonville. Commercial projects include high-capacity heaters, commercial ventilation, ADA-conscious layouts, and finishes rated for constant daily use.
Maintenance is simple: ventilate the room after each session, wipe benches with a damp cloth, and lightly sand any water spots once or twice a year. Because we build with proper vapor barriers and ventilation for Florida's climate, humidity-related problems are rare. We provide a full care guide at your walkthrough.
A comfortable two-person sauna needs roughly 4 by 6 feet, while a family-sized four-person room runs about 6 by 8 feet. Ceiling height stays near 7 feet to keep heat efficient. During your consultation we measure the space and recommend a size that fits both the room and the number of people who will actually use it.
Yes. We serve all of greater Jacksonville, including Jacksonville Beach, Atlantic Beach, Neptune Beach, Ponte Vedra, Nocatee, St. Johns, Orange Park, Fleming Island, and Mandarin. As a we-come-to-you service business, every consultation, build, and installation happens at your property.
