Availability

Most of our products are in stock and ready to ship right away. Unless a product is specifically labeled as custom, you can expect your order to be fulfilled without delay.

Processing

Order processing fluctuates depending on seasonality. Refer to the estimated delivery date on this page, or contact us for the current processing and delivery timeline.

Shipping

The heater weighs 33 lb without stones and ships boxed. Sauna stones are a separate shipment. Standard delivery is curbside. White-glove placement is available for an additional fee based on location; contact us for a quote.

ASSEMBLY

The heater ships in pieces. Assemble it on site before connecting the propane.

Set the heater base on a stable, level, non-combustible surface.
Seat the heat chamber fully onto the burner.
Slide the stone basket on and turn it clockwise until it locks to the base.
Attach the included heater guard. Up to three guards can be used.
Load 44 lb of stones. Order two 33 lb boxes and load 44 lb. Stack the stones with small gaps for airflow, and do not force them tight.
Connect the included regulator and 6 ft hose only after the heater is in place and the clearances are checked. The regulator connects to the propane cylinder valve. Do not substitute the hose or regulator.

INSTALL

Install the heater only as described in the installation manual. The installer needs to be familiar with fuel-burning appliances and gas safety. A cabin install may require a licensed professional where local code requires it.

Propane (LP) only. Keep the cylinder and regulator outside the sauna, upright, in a ventilated spot. Keep the hose at least 12 inches from the heater, and keep it off sharp edges.

Set the heater on a non-combustible base. Do not set it on a wood floor or on grass. In a tent, use a stone paver.

Clearances are measured from the outside of the stone basket. Without the heat shield: 6 inches to each side and the rear, 16 inches in front, and 50 inches to the ceiling. The optional heat shield brings the cabin side and rear clearance to 4 inches. The shield stays at least 1 inch off any wall and must not touch a wall or a bench. In a SaunaTrekker tent, the 6 inch side and rear clearances apply with or without the shield.

In a tent, install it only in a SaunaTrekker or SaunaTrekker XL, in the corner that has the lower air intake. In a cabin, provide a lower intake of at least 54 square inches and an upper exhaust of at least 39 square inches on the opposite wall, near the ceiling, discharging outdoors. Leave those vents fully open while the heater is running. There is no electrical connection.

Great Cold Plunge Tub

This is a great cedar-sided cold plunge tub. I spent a considerable amount of time researching cold plunge tubs and wanted one with real ceder wood to fit my sauna room. It also has a durable heat pump, compared to lower-quality chillers. I have had it a few months and no issues. Also, in the pics below, I have the chiller, which is about a 2' x 2' cube plumbed to a different space for a clean sauna room look. I would highly recommend this tub and the price is less than some on the market.

These guys are AMAZING!

These guys are AMAZING! I’d leave 10 stars if I could. We purchased a barrel sauna and cold plunge from them in fall 2025. They were absolutely terrific to work with! Our contractor and electrician had many (many) questions, all were promptly and kindly answered. They even customized our order by selling an extra long cord so we could install control panel inside for extra protection in MN winters. Shipping and delivery was a breeze. We are using our sauna daily and love it! Zero hesitation recommending this company! Thank you Johnny and Mitch for all your help!!!

What a wonderful sauna!

Researched many saunas for many months. Finally landed on this one. Only complaints i have are the instructions weren't very well written and the trim on the outside was very difficult to put together. We use it almost daily.

Great service, great sauna

Super stoked about the new sauna. I ended up with a beautiful 2-3 person cedar sauna with a huum heater. It’s perfect. These guys were helpful in choosing the right size, type, etc.
very glad I used the cold plunge guys.
