Rustic Fir
Rustic Fir is lighter in color with small tight knots that give its rustic appearance. Rustic Fir is our most popular lumber for indoor saunas and is also ideal for exterior applications. The exterior of the sauna can be left natural or stained or painted as desired. This lumber is sourced from North America.
Note: Due to the size of the Princeton, specialized shipping is required. Please anticipate this shipping anywhere from 3-6 weeks from the date of order.
Either you are tall, you like a lot of room, or both. No matter your reason, the Princeton fits the bill! At eight feet long, the Princeton has the largest interior of our barrel sauna rooms.

Care & Maintenance
Traditional saunas require very little upkeep. Simply wipe down the interior after each use and check for any dust or debris that you may have tracked in. Read more about long-term care and maintenance here.
Sauna Type
Heater and stones are essential to a traditional sauna experience. With the room at least heated to 160ºF, the traditional sauna can be enjoyed two ways. The first is called a dry sauna, which lacks any added moisture. The second is called a wet sauna, where you sprinkle water onto the heated stones to create a refreshing burst of steam and added humidity.
Assembly
Some basic handyman skills are helpful when assembling the sauna. The only additional equipment needed is a cordless drill. Two people can generally do the assembly in 6 hours or less. It is recommended that you review the assembly manual in advance to familiarize yourself with the process.

Feel the Heat in a Classic Barrel Sauna
We first started making our signature Barrel Sauna nearly 40 years ago, and it’s become a popular option on our product line ever since. The Barrel Sauna is assembled using a ball-and-socket profile held in place by stainless steel bands and minimal fasteners, the significance of this configuration being that it maintains a reliable seal while allowing the lumber to expand and contract. The entire unit is mounted on polymer support cradles that loft the undercarriage of the sauna and keep it from coming in direct contact with any moisture on the ground.


Build the Princeton
The simple grace of a barrel-shaped sauna is found in its ball-and-socket profile, held in place by sturdy stainless-steel bands and minimal fasteners. This arrangement allows the lumber staves to expand and contract to form a tight seal, and the unit sits on polymer support cradles that lift the sauna undercarriage off the ground. The Classic Barrel Sauna is an expressive take on our Classic Barrel Sauna – a design noted for its efficiency, even distribution of heat, and visual appeal. By taking the front round section and setting it back into the sauna, we’ve created a visually appealing and useful outside sitting area – a place to hold towels or drinks or to serve as a relaxing place to cool off between sauna rounds.
