BUILT FOR GATHERINGS
Room for the Whole Circle
With space for up to seven, the S6 is the model you buy when soaking becomes a shared ritual — long evenings, easy conversation, everyone in the water at once.
THERMO-TREATED TIMBER
Weathered by Design
The thermo-treated spruce surround is kiln-hardened to shrug off rain, frost and sun. Tight joinery and a marine-grade liner mean it ages with character, not wear.

The Gathering Place
A Fire, Seven Seats, and the Whole Evening Ahead
The S6 is the Soak Series at its most generous — the tub you choose when soaking becomes something you share. Thermo-treated wood, wood-fired heat, and room for seven, delivered fully assembled and ready for a lifetime of long, unhurried evenings.
to a friend
The S6 wood-burning hot tub has completely changed our winters. There is nothing like soaking in steaming water while it snows, heated entirely by a crackling wood stove. The cedar tub is beautiful and well crafted. It does take a few hours to heat from cold, so plan ahead, but the heat is steady and deep once there. Curbside freight delivery went smoothly.
We wanted a hot tub that did not need electricity and the S6 delivered exactly that. The internal wood-burning heater warms the water faster than I expected and holds temperature for a long soak. The cedar staves are gorgeous and the build quality feels heirloom level. Assembly took an afternoon. Perfect for recovery after long ski days.
This tub is a showpiece. The cedar is thick and finished beautifully, and the wood-fired heat feels more authentic than any electric tub I have used. Plan for a couple hours of heat-up time from cold and feed the stove steadily. We use it as a family two or three nights a week. The freight crate arrived curbside in great shape.
We love the S6 but want to be honest that the wood-burning heat-up is not instant; from cold it takes us close to three hours to reach a comfortable soak. Once it is hot it stays hot for a long time, so we just plan our evenings around it. The cedar craftsmanship is outstanding and it looks incredible on the deck. Worth it for the off-grid experience.
I bought this primarily for muscle recovery and it has been excellent. Sinking into hot cedar-scented water after a hard training day is unbeatable. The wood stove is simple to run once you get the rhythm. Build was straightforward and the included instructions were clear. Highly recommend for athletes who want something off the grid.
The whole family gathers around the S6 on weekend nights now. The cedar tub is beautiful, the wood-burning heat is cozy and steady, and there is plenty of room. Yes, you need to plan for heat-up time, but stoking the fire is part of the charm. Delivery was curbside freight and the team scheduled a window with us. Love it.
Every detail of this tub feels considered, from the tight cedar staves to the well-built internal stove. It holds water temperature impressively well even on cold nights. The off-grid wood-fired design means no electrician needed, which sold me. A genuinely beautiful and functional piece for the backyard.
