The Dynamic Cold Therapy CUBOID XL 304 Nano-Coated Stainless Steel Cold Plunge (DCT-S-055-NS-34) combines spacious cold-water immersion with premium construction and a clean, contemporary design. Featuring a 304 nano-coated stainless steel interior, matching nano-coated stainless steel exterior cabinet, and Pacific Cedar trim, this XL plunge tub is designed for homeowners seeking a dedicated cold plunge experience.
With an exterior length of 55 inches and an interior length of 48.5 inches, the CUBOID XL offers additional soaking space compared with the standard 50-inch model. Its rectangular design provides a comfortable immersion area, while the included Pacific Cedar entry step makes entering and exiting the tub more convenient. An insulated cover with locking safety latches helps protect the water when the plunge is not in use.
The CUBOID XL includes preconfigured 3/4-inch inlet and outlet connections for compatible Dynamic Cold Therapy cooling and heating systems. Pair it with an optional chiller to add adjustable water temperature control, filtration, and circulation. This product includes the cold plunge tub only; the chiller is sold separately.

Important: A cooling and heating chiller is not included with the tub-only configuration. Powered water circulation, temperature control, filtration, ozone sanitation, and Wi-Fi functionality require separately purchased compatible equipment.
The Dynamic Cold Therapy CUBOID XL is designed for installation on a smooth, level, structurally sound surface capable of supporting the tub, water, and user. Its stainless steel construction and Pacific Cedar trim make it suitable for a dedicated indoor wellness area or a properly prepared outdoor location.
Foundation and Placement: The tub measures 55 inches long, 32.5 inches wide, and 31.5 inches high. The manufacturer's CUBOID manual lists an empty weight of 207 pounds for the large stainless steel model. Confirm that the foundation, floor, or deck can support the filled tub, water, occupants, and any additional equipment before installation.
Indoor Installation: Position the tub on a waterproof, stable surface near suitable water access and drainage. Avoid carpeting and moisture-sensitive floors. Keep electrical devices away from the plunge area and provide adequate ventilation to manage humidity.
Outdoor Installation: Install the tub on a level surface free of sharp objects and debris. The manufacturer recommends protecting it from prolonged direct sunlight and providing appropriate drainage. Do not store or operate the tub in freezing conditions contrary to the manufacturer's instructions.
Optional Chiller Connections: The tub includes 3/4-inch inlet and outlet ports for compatible cooling and heating equipment. When connecting a chiller, route the tub outlet to the chiller inlet and the chiller outlet to the tub inlet according to the manufacturer's setup guide. Confirm the correct fittings, gaskets, and flow requirements for the selected chiller.
Electrical Requirements: The standalone tub does not require electricity for powered heating or cooling because those functions are not included. Electrical requirements are determined by the separately purchased chiller. Follow the selected chiller's installation manual and applicable electrical safety requirements.
Initial Inspection and Filling: Inspect the tub, stainless steel interior, valves, drain, and plumbing connections for shipping damage before filling. Confirm that the drain is closed and gradually add clean water, checking for leaks. The manufacturer's manual recommends starting with a lower fill level and adjusting it to account for water displacement when entering.
The CUBOID XL provides a spacious basin for cold-water immersion. The tub-only configuration does not independently chill, heat, circulate, or filter water. Water temperature depends on the water added to the tub or the settings of a separately purchased compatible cooling and heating system.
Important: Cold-water immersion can place substantial stress on the cardiovascular and respiratory systems. Avoid plunging alone, enter feet first, and exit immediately if you experience dizziness, chest discomfort, breathing difficulty, weakness, or loss of coordination. Consult a healthcare professional before cold immersion if you have cardiovascular concerns or other relevant medical conditions.
