Our picks at Caldera

Golden Designs St. Moritz 2-Person Barrel Sauna — $5,366.55 with SB926

A traditional outdoor barrel sauna in Pacific premium cedar, with a 6.0kW stove to 190°F (ideal range 170–185°F), a bronze privacy glass door, backrest accent lighting, and a bucket, scoop and sandglass included. 75” W × 60” D × 80” H, 409 lb.

The stove needs a dedicated 240V/30A circuit (240V/40A if you upgrade to the optional 8.0kW stove), with a separate 120V/15A circuit for the lighting. Plan on an electrician.

It’s one of the least expensive ways into a real wood-fired-style traditional sauna experience outdoors. For comparison, Sun Home’s traditional Nova starts at $11,799 with our code, though it’s an indoor cabin with a very different build.

Dynamic Cold Therapy Barrel Cold Plunge (stainless) — $3,376.30 with SB926

A Pacific cedar barrel with a 304 stainless steel interior, an ergonomic built-in seat, a cedar access step, and a custom cover with child safety latches. 42” wide, 39.5” tall, 255 lb, indoor or outdoor, 1-year warranty.

Important: this price is the tub only. It needs a chiller for cold water without ice. Pair it with Dynamic Cold Therapy’s 0.8 HP Wi-Fi chiller ($3,499, cools to 37°F and heats) and the full system is $7,053, or $6,700.35 with SB926.

Know the return terms first

Caldera’s policy, checked 14 September 2026:

• 30-day return window from receipt
• Items must be unused, undamaged, in original packaging with labels attached
• 20% restocking fee, and you pay return shipping
• Damaged or defective items must be reported within 48 hours with photos
• Golden Designs: 24-hour cancellation window
• Orivon Wellness: all sales final, except defective items

On a freight-shipped sauna, a 20% restocking fee plus return freight is a lot of money. Measure your space, confirm your electrical supply, and be sure before ordering.

Also have Sun Home on your list?

We also have a Sun Home code: WELLWORTHIT saves $200 on Sun Home orders over $4,000, including every Sun Home sauna and the Pro Series cold plunges. See every Sun Home price with the code on our Sun Home promo code page.

A quick safety note

Traditional saunas run hot — this one reaches 190°F. Hydrate, keep sessions reasonable, cool down gradually, and never use a sauna after drinking. Cold plunging triggers a real cold-shock response, so start short and never plunge alone. If you’re pregnant, have a heart condition or blood pressure concerns, or take medication affecting heat or circulation, talk to a doctor first.
