The Round Barrel Cold Plunge — Deep Stand-In Cold Therapy. Three Finishes. Your Setup. The Round Barrel is a tall, upright stand-in cold plunge designed for full-body cold immersion from the shoulders down. Crafted from premium natural wood with a 304 stainless steel interior, it's the most space-efficient way to get a serious, deep cold plunge — indoors or out. Available in three stunning finishes and with or without a chiller. Deep Stand-In Design — Maximum Immersion At 1000mm (39.4 in) tall with a 793mm (31.2 in) interior diameter, the Round Barrel is built for deep, upright immersion. The internal stainless steel seat bar lets you brace and stay submerged comfortably — no floating, no slipping, just full cold exposure every session. Three Premium Finish Options Thermo NZ Knotless Spruce — The lightest, cleanest finish. Knotless New Zealand Spruce thermally treated for superior weather resistance and a smooth, refined look. Perfect for modern outdoor spaces. Thermo Pine Wood — A warm, rich mid-tone finish. Thermally treated pine with beautiful grain variation — classic barrel aesthetics that age beautifully outdoors. WPC (Wood Plastic Composite) — The bold, low-maintenance option. Charcoal black finish with zero rot, zero splinters, and zero upkeep. Built for those who want the look without the maintenance. 304 Stainless Steel Interior The fully welded stainless steel inner vessel is hygienic, non-porous, and built to last. The interior support bar doubles as a grip and seat — making entry, immersion, and exit safe and comfortable. Entry Steps Included Every Round Barrel ships with matching entry steps — two-tier, in a finish that matches your tub. No awkward climbing, no added cost. Chiller — Your Choice Buy the Round Barrel on its own and add ice, or upgrade with our external chiller unit for precise, app-controlled temperature management year-round. The chiller connects directly to the tub via hose fittings and sits neatly beside your setup.
