Product details
The Square Cedar Cold Plunge — The Most Spacious Stand-In Cold Plunge We Make.
Bold. Architectural. Unapologetically deep. The Square Cedar Cold Plunge is a full-immersion stand-in tub built for those who want maximum interior space, effortless entry, and a design statement that commands any outdoor space. With a 900 × 900mm (35.4 × 35.4 in) interior, it's the roomiest cold plunge in our lineup — and at 1400mm (55.1 in) tall, it delivers the deepest full-body immersion available.
Square Interior — Maximum Space, Zero Compromise The square basin gives you more usable interior room than any round or oval tub of similar footprint. Stand, stretch, and fully submerge — there's room to move and room to breathe. The chamfered stainless steel corners prevent sharp edges while maintaining the clean geometric aesthetic, and the interior seat ledge lets you brace and relax at any depth.
1400mm (55.1 in) Deep — Shoulder-to-Toe Immersion At 1.4 meters tall, this is the deepest cold plunge in our collection. Full shoulder immersion, full leg immersion, full cold shock — every session delivers the maximum physiological response that cold therapy has to offer.
Handcrafted Red Cedar Exterior Tight-grain vertical Red Cedar slats wrap the square frame in warm, natural beauty. Naturally rot-resistant, weather-sealed, and UV stable — it ages gracefully outdoors year after year. The clean aluminum trim ring at the top ties the look together with a refined modern edge.
3-Step Cedar Entry Staircase — Included Climbing into a 1400mm (55.1 in) deep tub requires serious steps — and we've included a substantial 3-step solid cedar staircase as standard. Wide, sturdy, and beautifully matched to the tub's cedar finish. Safe entry and exit every single session.
304 Stainless Steel Interior The fully welded food-grade 304 stainless steel inner vessel is smooth, non-porous, and built to last for decades. Zero cracking, zero staining, zero compromise on hygiene.
Built-In Drain Valve Draining and refilling is simple with the integrated stainless steel drain valve — no siphoning, no mess.
Chiller — Your Choice Buy the Square Cedar tub on its own and add ice for an instant cold plunge, or pair it 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.

Questions
Do I need the chiller?
Choose the chiller option to cool (and heat) the water automatically. Without it, you fill the tub with cold water and ice. You can add a chiller later — the tub has a water inlet and outlet ready for it.
How deep is it?
55 in (1400 mm) tall — the deepest plunge in our lineup.
Is delivery included?
