Convenient Cold? These are the Best Cold Plunge Tubs in 2025
The Ultimate Cold Plunge Guide (2025)
We learned something early on in the sauna business: you never want to buy a sauna from a cold plunge company. The expertise just isn’t there. So when customers started asking us about cold plunges, we didn’t want to make the same mistake in reverse. We partnered with the best—Plunge Junkies—to make sure we’re recommending equipment that actually performs.
After years of hands-on installs and thousands of conversations with cold therapy practitioners, our team at Sauna Marketplace knows what lasts and what ends up on Facebook Marketplace six months later. This guide focuses on tubs that work.
Aquavoss Model 1
$5,850 — Free Shipping, Financing Available
Here’s the thing about cold plunges: the best one is the one you’ll actually use. The Aquavoss Model 1 removes every excuse.
That stepped entry design isn’t a gimmick—it’s the reason people stick with their practice. We’ve watched customers abandon perfectly good cold plunges because climbing over a wall at 5 AM in the dark felt like too much. The Model 1’s built-in steps make entry natural, especially for aging joints or post-workout fatigue.
What sets it apart:
✓ Integrated Panasonic compressor chiller — Reaches 39°F without ice runs or external units
✓ Ozone sanitation — Self-cleaning technology means less maintenance
✓ 2-inch spray foam insulation — Holds temperature even in extreme heat
✓ Concealed components — Looks like furniture, not industrial equipment
✓ Weather-resistant acrylic shell — Built for outdoor use
The team at Plunge Junkies put us onto Aquavoss specifically because of their customer service reputation. When you’re buying equipment with refrigeration components, responsive support matters. We’ve verified it ourselves.
Also Excellent: Modular Options

Why These Made the Cut
