Dundalk Leisurecraft The Flow Cold Plunge: Full-Body Immersion, Fully Assembled
The Dundalk Leisurecraft Flow Cold Plunge is a premium rectangular cold plunge with a stainless steel interior, natural cedar exterior, and a fully concealed chiller compartment built into the shell. It ships fully assembled — connect your chiller, fill with water, and you're ready to go. No multi-hour build, no loose panels, no guesswork.
Full-Body Immersion in Stainless Steel
The Flow's stainless steel basin measures 45-7/8" long by 26-1/2" wide — large enough for full-body submersion. Stainless steel is the gold standard for cold plunge interiors: it's hygienic, won't absorb bacteria or odors, cleans easily, and lasts indefinitely. Unlike plastic liners that can degrade, stain, or develop biofilm over time, stainless steel stays clean with minimal maintenance. If you're running your plunge daily, that matters.
Concealed Chiller Compartment
Most cold plunges leave the chiller sitting next to the tub as a separate box with hoses running between the two. The Flow integrates the chiller compartment directly into the outer shell. The chiller (sold separately) tucks inside a dedicated section at one end of the unit, so everything looks like a single, finished piece of furniture. No exposed hoses, no external equipment cluttering your space.
Natural Cedar Exterior
Choose between Knotty Cedar for a rustic, textured look or Clear Cedar for a smoother, more uniform grain. Both are Eastern White Cedar — naturally rot-resistant, weather-durable, and designed to complement the rest of Dundalk Leisurecraft's Canadian Timber Collection. The cedar develops a silver-grey patina over time outdoors, or you can seal it to preserve the original warm tone.
Ships Fully Assembled
The Flow arrives as a complete, ready-to-use unit. At 81" long by 30" wide by 30" high, it's a substantial piece — plan for freight delivery and have a clear path to its final location. Total shipping weight is 575 lbs in the crate (86" × 45" × 44"). You'll need to connect the chiller and fill with water, but there's no structural assembly required.
Chiller Sold Separately
The Flow is designed to work with the Penguin Cold Therapy Chiller, which fits inside the concealed compartment. The chiller maintains water temperature as low as 37°F, so you never need to haul ice. Add the chiller during checkout to save on the bundled price.
Available Add-Ons
Complete your setup with accessories designed specifically for the Flow. The 2 Tier Steps with Straight Top Tread make getting in and out of the plunge safe and easy — two 7" steps in matching cedar bring you from ground level to the tub rim. The 16" Square Tub Shelf hooks onto the edge of the plunge and gives you a spot to set your phone, towel, or water bottle while you soak. And the Insulated Vinyl Cover keeps your water temperature stable between sessions and blocks debris — a must-have if you're running a chiller.
Every Dundalk Leisurecraft cold plunge is handcrafted in Ontario, Canada and backed by a 5-year parts warranty. Questions about the Flow, chiller compatibility, or installation? Call us at (888) 833-2305 — we're here 7 days a week.
