Short answer: the Siberian Pro is Renu Therapy’s largest cold-only plunge: 80” long, a 0.8 HP chiller, and a wood entry deck, for $14,099. It is the most expensive cold plunge on this site. It has a 1-year warranty, which is hard to accept at this price.
Who needs a tub this big?
The exterior is 80” x 33⅝” x 37”, about 18.7 sq ft. That is 10” longer than Renu’s Cold Stoic models. The extra length is for tall users who want to lie fully stretched out.
It weighs 650 lbs empty. Our data doesn’t state the water capacity or the filled weight. Ask for both, because a tub this size will be well over 1,000 lbs filled. Plan on a concrete slab. Indoors, get an engineer’s opinion.
What does a 0.8 HP chiller do?
It is the strongest chiller rating we have on record, matched only by Renu’s Vero. A larger chiller cools faster and recovers faster after a session. The listing says it runs on a standard 120V/15A circuit. Ask for the nameplate amps, and give it a circuit of its own.
It cools to 37°F. There is no heating mode.
Run the numbers on the warranty
One year. Renu’s Cold Stoic 2.0 and Vero are listed with 5 years, and both cost thousands less. I’d ask Renu directly why the flagship has the shortest term, and whether a longer one can be written into the sale.
Here’s what the spec sheet won’t tell you
- Water capacity and filled weight
- Chiller amperage and noise level
- Lead time for your color choice
There are 5 tub colors and 2 deck colors. Custom finishes often take longer to ship.
You get, you give up
You get a step and breath deck for stable entry, 3-inch insulation, and an XL filter with ozone. You give up heating, warranty length, and about $4,600 against the Cold Stoic 2.0.
How it compares
The Renu Vero has the same 0.8 HP rating, a 5-year warranty, and a $7,200 price, in a compact upright form. Our button goes to Renu Therapy’s product page. See Cold Plunge Warranties Compared.
