Cold plunging — immersing your body in water between 37°F and 60°F — has moved from athletic recovery rooms into home wellness routines. The practice triggers vasoconstriction followed by vasodilation, which helps reduce inflammation, accelerate muscle recovery, and deliver a norepinephrine-driven mental boost that can last for hours. Whether you're an athlete using cold therapy for recovery, someone exploring contrast therapy with a sauna, or simply looking for a daily energy and mood boost, there's a cold plunge for every budget and setup. Our collection includes handcrafted wood tubs with built-in chillers, cedar barrels, portable inflatables, insulated ice barrels, and standalone chiller systems from brands like SaunaLife, Dundalk, Dynamic Cold Therapy, Ice Barrel, Kohler, and Therasage.

These are the premium, ready-to-use option — a beautiful wood tub with the chiller, filtration, and sanitation system built in or included. Fill with water, plug in, set your temperature, and plunge. No ice, no separate chiller to buy, minimal maintenance.
Kohler × Remedy Place Ice Bath — An 85-gallon cold plunge from Kohler (yes, the plumbing company) in partnership with Remedy Place, a social wellness club. App-controlled temperature, premium build quality backed by the Kohler name. The high end of the cold plunge market for buyers who want a recognized brand and smart-home integration.
These tubs are sold as the vessel itself. You can use them with bags of ice for the lowest upfront cost, or pair them with a standalone chiller system for always-ready cold water. This approach lets you start simple and upgrade later.
Dynamic Cedar Cold Plunge Barrel — A cedar barrel designed specifically for cold immersion. The barrel shape is space-efficient and naturally insulating. Pairs with the Dynamic Cold Plunge Chiller & Heater System for automated temperature control, or use with ice.
Dynamic Cuboid Cold Plunge Tub — A rectangular cold plunge tub that pairs with the Dynamic chiller system. The cuboid shape gives you a full-body immersion position and a more traditional tub layout compared to the barrel.
Dundalk LeisureCraft Baltic Cold Plunge Tub — Made in Canada from Eastern White Cedar. Dundalk is the same company that makes some of the most popular outdoor barrel saunas, so the build quality and cedar craftsmanship carry over to their cold plunge line. Designed to match Dundalk's sauna aesthetic if you're building a full contrast therapy setup.
Dundalk Polar Plunge Tub — Another Canadian-made cedar cold plunge from Dundalk. Built for durability and outdoor use with the same stain-resistant cedar construction as their saunas.
SaunaLife Cold/Hot Plunge Tubs (S1 & S2) — SaunaLife offers 1-person (S1N and S1B) and 2-person (S2N and S2B) tubs made from thermo-pine, a heat-treated wood that resists moisture, rot, and warping. Available in natural wood or black finish. These are cold/hot plunge tubs — they can be used for cold therapy or heated for hot soaking, making them versatile for year-round use. Pair with a chiller for automated cold plunging.
The most affordable entry point into cold plunging. Inflatable tubs pack down for storage or travel and set up in minutes. They work indoors or outdoors and pair with a chiller for consistent temperature, or use ice for a simpler setup.
Dynamic Inflatable Round Cold Plunge — A round inflatable tub that pairs with the Dynamic chiller system. Comes with an anti-slip mat, manual pump, and carry bag. A cost-effective way to start cold plunging — portable enough to move between indoor and outdoor setups. Can cool down to 39°F with the chiller or use ice.
Dynamic Inflatable Oval Cold Plunge — Same concept as the round, but the oval shape offers more room to stretch out during immersion. Both Dynamic inflatables are built to last for years despite the inflatable form factor.
Therasage TheraFrost — A portable cold plunge system with a built-in ozone generator for water sanitation. WiFi-capable for temperature control from your phone. Ozone filtration means less chemical maintenance compared to traditional filtration methods. A good middle ground between budget inflatables and premium wood tubs.
If you already have a tub (or you're buying one of the tubs above that doesn't include a chiller), a standalone chiller system keeps your water at a set temperature 24/7 without ice. Most include filtration and sanitation so the water stays clean between sessions.
Dynamic Cold Plunge Chiller & Heater System — Available in 0.8 HP and 1.0 HP options. Cools down to 37°F and can also heat water for hot soaking. Includes filter, fittings, and hoses. Wheels and steel handles for portability. Compatible with all Dynamic tubs and most other cold plunge vessels.
Penguin Cold Plunge Chiller — A high-performance chiller with an included filter kit. Penguin Chillers are known in the cold plunge community for reliability and cooling power. A popular aftermarket chiller for any tub or barrel setup.

Built-in chiller vs. ice-only vs. separate chiller: Built-in chiller tubs (Kohler) are the most convenient — plug in and go. Separate chiller systems (Dynamic, Penguin) give you flexibility to choose your tub and chiller independently. Ice-only (Ice Barrel) has the lowest upfront cost but requires ongoing ice purchases. If you plan to plunge daily, a chiller pays for itself quickly in ice savings and convenience.
Indoor vs. outdoor: Most cold plunges work in either setting. For indoor use, read our indoor installation guide — you'll need to consider drainage, flooring protection, and electrical requirements. Outdoor setups are simpler for drainage but need to account for weather and insulation in cold climates.
Size and capacity: Most tubs fit one person comfortably. SaunaLife offers 2-person models (S2N/S2B) for couples or larger bathers. If you're tall, check our guide to cold plunge tubs for tall people. For gyms and commercial spaces, see best commercial cold plunge tubs.
Budget: Inflatable tubs start under $1,000. Ice Barrels and basic wood tubs fall in the $4,500–$8,000 range. Handcrafted wood tubs with built-in chillers run $5,000–$15,000+. The Kohler × Remedy Place sits at the luxury end. For budget strategies, read budget-friendly cold plunge solutions or explore financing options.
In many cases, yes. Cold plunge tubs may qualify as HSA/FSA-eligible medical expenses if prescribed by a healthcare provider for a specific condition. The rules can be nuanced — we wrote a detailed guide covering the eligibility requirements, how to get a Letter of Medical Necessity, and which expenses typically qualify: Are Cold Plunges HSA/FSA Eligible?
Most cold plunge practitioners recommend 50°F (10°C) as a starting point. More experienced plungers often go down to 39–45°F (4–7°C). Start warmer and work your way down as your body adapts. Sessions of 2–5 minutes deliver most of the benefits. For protocol recommendations, see our optimal cold plunge frequency guide.
You can absolutely start with ice — it's how most people try cold plunging before committing to a chiller. Ice Barrel products are specifically designed for this approach. The downside: you'll spend $15–$30 per session on ice (more in summer), the temperature is less consistent, and prep time adds friction to your routine. If you plan to plunge more than 2–3 times per week, a chiller typically pays for itself within a few months and removes the biggest barrier to consistency.

Yes. Many of our customers install cold plunges in bathrooms, basements, garages, or dedicated wellness rooms. The key considerations are drainage (you need a floor drain or a plan for water changes), flooring that can handle moisture, and a nearby electrical outlet for the chiller. Our indoor installation guide covers everything step by step.
Contrast therapy — alternating between hot (sauna) and cold (plunge) — is one of the most popular wellness protocols. The combination of heat exposure followed by cold immersion amplifies the cardiovascular and recovery benefits of each. Many of our customers buy a sauna and cold plunge together.
