Dundalk Leisurecraft The Polar Plunge Tub: Full-Body Cold Immersion, Handcrafted in Canada
The Dundalk Leisurecraft Polar Plunge Tub is a full-length rectangular cold plunge built for complete head-to-toe immersion. At 190 gallons and nearly six feet long, this is the tub for anyone who wants to fully stretch out during cold therapy — not sit hunched in a barrel. Choose between a White HDPE Plastic interior for an accessible entry point or upgrade to a premium 304 Stainless Steel interior for commercial-grade durability and a sleek, modern look. Both options are wrapped in thick 1-3/8" Eastern White Cedar skirting from Dundalk Leisurecraft's Canadian Timber Collection.
Two Interiors, One Premium Build
The White HDPE Plastic interior features a 3/4" thick base and floor with 1/4" thick upright walls — durable, watertight, and easy to clean. The 304 Stainless Steel interior uses 11-gauge surgical-grade stainless throughout for maximum longevity, hygiene, and a striking industrial aesthetic. Both interiors sit inside the same beautiful Eastern White Cedar frame with 1-3/8" thick skirting — nearly double the thickness of standard cedar plunge tubs. Whichever interior you choose, the build quality is unmistakably Dundalk Leisurecraft.
190 Gallons of Full-Length Immersion
At 71" long and 19" wide on the interior, the Polar Plunge Tub lets you lie down flat for proper full-body cold exposure. The 190-gallon capacity means you're fully submerged — shoulders, arms, legs, everything. This is a significant step up from barrel-style tubs where you sit upright with knees bent. If recovery, athletic performance, or deep cold therapy is the goal, full-length immersion is the way to go.
Ice or Chiller — You Choose
Use bags of ice to bring the water to your target temperature, or connect an optional electric chiller through the built-in 3/4" NPT openings for hands-off temperature control down to the high 30s°F. The chiller also filters your water, keeping it clean between sessions. The ball valve drain with garden hose connector makes water changes effortless.
Assembly Required — Worth Every Minute
Unlike the barrel-shaped Baltic, the Polar Plunge Tub requires assembly — plan for 4–6 hours with 2 people. The assembly manual walks you through every step, and the result is a rock-solid rectangular plunge tub that will last for years. You'll need an adjustable wrench, pipe wrench, and the included thread tape for drain hardware installation.
The Perfect Companion to Your Sauna
Designed to complement Dundalk Leisurecraft's Canadian Timber Collection saunas, the Polar Plunge Tub creates an authentic contrast therapy experience right in your backyard. Alternate between the heat of your sauna and the cold of the plunge tub to boost circulation, reduce inflammation, and accelerate recovery. The matching cedar aesthetic ties your entire outdoor wellness space together beautifully.
Customize Your Setup
Start with the base tub and add optional accessories to build your ideal cold plunge station. The lockable Roll-Up Cover keeps debris out and retains water temperature — it also prevents unauthorized access when locked. For automated temperature control, pair with the Penguin Cold Therapy Chiller or the Coldture Water Chiller Pro — both available at significant savings when bundled with the tub.
Every Dundalk Leisurecraft product is handcrafted to order in Ontario, Canada, backed by a 5-year parts warranty and our lifetime expert support.
