Custom backyard sauna

The first law of löyly

Your feet belong
above the rocks.

Heat and steam pool at the stones. If your feet sit below that line, you get a sauna that's scorching at the head and cold at the floor — the most common flaw in a badly designed hot room.

Raising the footrest above the top of the heater's stones fixes it. Most builders sell that as an upgrade. We build it in.

01
Balanced heat, floor to ceilingFeet stay in the coolest air in the room while your head takes the full löyly.
02
Standard on select modelNot a line item, not a tier — it's how the benches are drawn from the start.
03
Taller rooms where it countsAn 8'6" Feet Over The Rocks upgrade is available on select models for deeper stratification.

How it's built

The parts you
never see.

A sauna lives or dies on its envelope. Ours is built to survive Michigan winters and decades of steam — because the difference between a good hot room and a great one is entirely behind the cedar.

01

Structural aluminum frame

Welded aluminum with integrated lift pockets, so the cabin can be craned or shed-moved onto site without racking. It won't rot, and it won't move.

02

Sealed, not just wrapped

A true sauna-grade vapor barrier — never the plastic-reinforced kind — with every seam, joint, and opening taped and sealed by hand.

03

Rockwool insulation

Mineral wool in walls and ceiling. It holds heat, tolerates moisture, and doesn't slump the way lesser batting does.

04

1×6 cedar, inside and out

Tongue-and-groove Western Red Cedar lines the hot room and clads the exterior. Same species, same grade, both faces.

05

Standing seam steel

Black standing seam steel roofing standard, with aluminum, slate, copper, and zinc available as upgrades.

06

IKI & Homecraft heat

Commercial-grade 9kW and 15kW heaters, wall or pillar mount, with app-based WiFi control available across the range.

Our story

It started in our grandparents' backyard.

We are a family company with roots in Northern Michigan. We grew up spending summers and snowy weekends in our grandparents' wood-fired Finnish sauna, the one they built decades ago behind the house.

Health, warmth, laughter — and the unique rhythm of hot, cold, rest, rinse, repeat — shaped our childhood and left us with a deep love for authentic Finnish sauna culture.

Today we're committed to building saunas our Finnish ancestors would be proud of.
