Arti

The second-dearest sauna per seat in our data: $43,990 for 5 seats, delivered pre-assembled in thermowood and weighing 5,512 pounds.

At $8,798 per seat, Arti costs about 4.7 times the $1,868 cabin median and more than any model but the Sun Home Solaris 4 at $9,075. Only one store, Recovery for Athletes, lists it. What you get for that is a pre-assembled thermowood cabin with a porch, 111 by 87 inches and nearly 98 inches tall, and a weight of 5,512 pounds, about 4.7 times the median of 1,170 for models that state one.

What it takes

That weight means you need a proper base and a delivery plan, not a weekend and a wheelbarrow. Pre-assembled is rare here: only five models are. The data does not state the heater power or a warranty length in years, and for a purchase this size you should get both in writing. For most buyers a 5-seat kit such as the Golden Designs Gargellen at $7,999, about a fifth of the price, does the same job.
