Site prep, then one day.

Your side is simple: a level pad, a dedicated 240V circuit, and clear crane access. We confirm all three during design. Then it is pad, crane, set, and the build is running the same day it arrives.

Paths to ownership

Cash, equity, or monthly.

There is no single right way to bring a sauna home. Some clients purchase outright, some fold it into a larger home project, and some prefer a monthly payment. We will help you find the path that fits.

Direct purchase

The simplest path. Purchase directly, lock in your build slot, and move straight into design. You own a hand-built structure engineered to last for decades.

Ideal for clients who are ready now and want their space in use as soon as possible.

Best for:

  • Cash purchases
  • Second homes and investment properties
  • Clients who want the simplest experience

Home equity

A sauna is a home improvement, and many clients fund it that way. We can connect you with professionals who specialize in home equity lending, so you can weigh a HELOC or similar option alongside your own financial advisor.

A concierge introduction, not a sales pitch. You decide with the people you trust.

Best for:

  • Backyard transformations
  • Larger outdoor and landscape projects
  • Clients leveraging existing home equity

Financing

Prefer a monthly payment? We work with financing partners experienced in luxury home and wellness projects and can introduce you during your consultation.

Available options vary with project scope and credit qualifications. We will walk you through what applies to your build.

Best for:

  • Monthly payment options
  • Residential projects
  • Clients who want purchasing flexibility

Not sure which path fits? Every project is different. Talk it through with founder Cole and leave with a clear plan.

Common questions.

Horizontal vs. vertical plunge, what’s the difference?

Horizontal is full-immersion, lying back, better for total-body cold exposure and shoulder relief. Vertical is upright, smaller footprint, and shorter dunks. The Thermal Suite uses horizontal; the Thermal Suite Designer uses vertical. Both run 38–55°F.

What electrical do I need on site?

240V · 50A dedicated sub-panel with RCD protection. Your local electrician pulls the permit and runs the feeder. We provide the drawings; your GC executes.

Foundation requirements?

Level pad, concrete, stone, or compacted gravel with helical piers. ~134 sq ft. Foundation requirements vary by region; we spec, your GC coordinates.

Will it work in my climate?

Yes, lower 48. Charred Accoya is weather-resistant from desert sun to snow load. Cold zones may add a winter cover for the plunge inlet.

Heat-up time?

~35–45 minutes from cold start to ~180°F. UKU Wi-Fi remote start gets it ready while you finish dinner.

What happens after I request a quote?
