Short answer: the Madison is a 2-3 person indoor cedar cabin with a 6kW heater and two bench levels for $4,786. It is a full traditional sauna in the floor space of a large wardrobe. It needs a hardwired 240V/30A circuit and patience: the lead time is 6-8 weeks.
Will it fit?
The exterior is 65” wide, 53” deep, and 77⅝” tall, about 24 sq ft. It clears a standard 8 ft ceiling. The interior is 60¼” x 48½”, so the bench is 5 ft long. One person can recline with knees bent. Three people sit upright.
What does the 6kW heater need?
At 240V, 6kW draws 25A. The listing calls for a dedicated 30A hardwired circuit, which means a licensed electrician connects it. There is no plug. At full power the heater uses 6 kWh per hour, about $1.10 at 18.34 cents per kWh, and less once it starts cycling.
You choose between a KIP heater with dial controls and a Spirit heater with app control. Decide which matters more to you: a simple dial that can’t lose its Wi-Fi connection, or the ability to start heating before you get home.
What does the warranty cover?
Here’s what the spec sheet won’t tell you at a glance. “Limited lifetime” applies to the cabin. The Harvia heater has its own terms: 1 year on the heating element and 5 years on other components. The element is the part that wears, so a replacement element is a cost to expect during the life of the sauna.
What to plan for
- The wood choice (red cedar or Hemfir) changes the look and the price
- The door comes in full glass or half-and-half
- The cabin can be upgraded later with infrared panels
You get, you give up
You get two bench heights, which give you a hotter upper seat and a milder lower one. You give up speed of delivery.
How it compares
The Almost Heaven Sutton costs $119 less, seats 2, and uses a corner layout. Bottom line: take the Madison if you want the third seat. Wiring an Indoor Sauna lists what to tell your electrician.
