Dynamic Cold Therapy Pacific Cedar Barrel Cold Plunge Tub
Authorized Dealer
Full manufacturer warranty
A pre-assembled Pacific Cedar barrel you fill, cover, and plunge. This 42 inch wide by 39.5 inch tall barrel plunge tub pairs a solid Pacific Cedar exterior with a built-in ergonomic seat, so one or two people can sink in without electrical, plumbing, or a heater. It runs cold on its own the moment it is filled. Add the optional chiller and you can hold the water in a true cold range, from 37 to 65 degrees F. Tub only; the chiller is sold separately.
PVC liner or 304 stainless steel
Both builds share the same Pacific Cedar barrel, ergonomic built-in seat, matching cedar step, and custom insulated cover. The PVC liner is the classic, budget-friendly interior that keeps the water contained and ready to plunge. The 304 stainless steel interior is a seamless, food-grade upgrade that resists staining, wipes clean easily, and gives the inside a bright, modern finish. Choose the interior that fits your setup.
Why cold immersion
Cold-water immersion is the second half of a contrast ritual: warm up in your sauna, then step out and lower yourself into the barrel for a sharp, repeatable cold exposure. With the optional chiller (120V, 15A) the water stays in a steady 37 to 65 degrees F band, so every plunge feels the same. Without it, you fill, cover, and plunge on your own schedule, which makes this an easy, low-commitment way to build a daily recovery habit.
What a daily plunge looks like
- Finish a sauna round, then drop straight into the barrel for a hot-and-cold contrast set on your patio or in your recovery room.
- Ease down onto the built-in ergonomic seat using the matching Pacific Cedar step, so getting in and out stays steady.
- Seal the custom insulated cover with its child safety latches between sessions to keep the water clean and covered.
Built for real life
- Best for: One or two people who want a compact, no-wiring cold plunge to pair with a sauna for contrast sessions.
- Included: Pacific Cedar barrel, ergonomic built-in seat, Pacific Cedar step, and a custom insulated cover with child safety latches.
Where it sits in the line: This is the barrel-style build in the Dynamic Cold Therapy cold plunge lineup. Choose the PVC liner to keep it simple, or the 304 stainless interior for a premium, easy-clean finish.

Good to know
Common questions about this cold plunge
Does it need electricity or a chiller?
No electrical required (optional chiller: 120V / 15A).
The tub itself needs no power; you fill it, cover it, and plunge. To hold cold water on demand you can add a chiller, sold separately, which is what most owners run for year round use.
How cold does the water get?
Documented water temperature: 37 to 65°F (with optional chiller).
Without a chiller, the water tracks your surroundings and any ice you add, so a chiller is the way to hold a repeatable cold plunge in any season.
Is it ready to use out of the box?
Nearly. 2 people, 60 minutes. Pre-assembled barrel; fill, cover, plunge.
There are no panels to build. The main effort is positioning it and filling it on a surface that can carry the weight once it holds water.
Can I use it indoors and outdoors?
Both. It is rated for indoor or outdoor placement.
Set it on a solid, level surface, a pad, a deck, or a reinforced floor, that can support the tub once it is full of water.
How is it delivered, and how long does it take?
It ships free by curbside freight. Free curbside freight delivery to your driveway. Typical lead time 10 to 20 business days. AK, HI, and Canada quoted separately.
Your carrier calls ahead to schedule a drop off window and leaves it at the end of your driveway, so plan to have a hand available to move it inside.
Are you an authorized dealer, and what warranty comes with it?
Yes. PureHeat is an authorized Dynamic Cold Therapy dealer, so this is a genuine unit that carries its full 1-year Dynamic Cold Therapy factory warranty, honored directly by the manufacturer. Register it within 60 days of delivery at the manufacturer registration form to activate coverage.
That matters on a purchase this size. Units from unauthorized gray market sellers often arrive with the factory warranty voided, which can leave you without support if a part ever fails.
