Dynamic Cold Therapy "CUBO" DCT-S-050-NS-34 304 Nano-Coated Stainless Steel Cold Plunge

The Dynamic Cold Therapy CUBOID 304 Nano-Coated Stainless Steel Cold Plunge (DCT-S-050-NS-34) combines premium construction with a comfortable rectangular design for cold-water immersion at home. Featuring a 304 nano-coated stainless steel interior, stainless steel exterior cabinet, and natural Pacific Cedar trim, this cold plunge tub offers a refined alternative to traditional barrel-style ice baths.

The standard-size CUBOID features a spacious soaking area and a contemporary design suited to dedicated indoor wellness rooms and properly prepared outdoor spaces. An included Pacific Cedar entry step makes entering and exiting more convenient, while the custom insulated cover with locking latches helps protect the water between sessions.

Designed for use as a standalone plunge tub or alongside an optional Dynamic Cold Therapy cooling and heating system, the CUBOID features preconfigured 3/4-inch inlet and outlet connections. Add a compatible chiller for electronic water temperature control, circulation, and filtration without the need to manually add ice before every session.

Important: This listing includes the cold plunge tub only. A cooling and heating chiller is sold separately.

Installation

The Dynamic Cold Therapy CUBOID DCT-S-050-NS-34 is intended for placement on a flat, stable, waterproof surface capable of supporting the full weight of the tub, water, and user. Proper location planning and access to drainage are essential for safe installation and convenient maintenance.

Dimensions and Foundation: The manufacturer's current product listing specifies exterior dimensions of 50 inches long, 32.5 inches wide, and 31.5 inches high. Its owner's manual lists an empty weight of approximately 200 pounds for the standard stainless steel CUBOID. Verify that the selected floor, deck, or foundation can support the tub when filled, including the weight of all occupants and accessories.

Indoor Installation: Position the cold plunge on a waterproof floor with adequate drainage and ventilation. The manufacturer's instructions recommend avoiding carpeting and other moisture-sensitive surfaces. Provide sufficient space around the tub for safe access, cleaning, and water replacement.

Outdoor Installation: Install the tub on a smooth, level surface free of sharp objects and debris. The manufacturer recommends keeping it protected from prolonged direct sunlight and providing suitable drainage nearby. Follow the owner's manual for protection against freezing conditions and other environmental exposure.

Optional Chiller Connections: The CUBOID includes 3/4-inch inlet and outlet ports for compatible cooling and heating equipment. When adding a chiller, connect the tub's water outlet to the chiller inlet and the chiller outlet to the tub inlet, following the manufacturer's approved connection diagram. Confirm the fittings, gaskets, and circulation requirements of the exact chiller before installation.

Electrical Requirements: The tub-only configuration does not contain a powered cooling or heating system. Electrical requirements depend on the optional chiller selected. Install any additional equipment according to its own manual, the manufacturer's recommendations, and applicable electrical codes.

Initial Inspection and Filling: Inspect the stainless steel interior, cabinet, cover, valves, and drain for shipping damage before filling. Close the drain valve and add clean water gradually, inspecting the plumbing connections for leaks. Allow room for water displacement when a user enters the tub to help prevent overflow.

Operation and Usage

The Dynamic Cold Therapy CUBOID provides a dedicated basin for cold-water immersion. The standalone tub does not independently cool, heat, filter, or circulate water. Users can fill the tub with appropriately prepared water or connect a compatible optional chiller for controlled water temperatures and additional water-care functionality.

• Preparing the Cold Plunge: Fill the tub with clean water to a comfortable level that allows immersion while keeping your head above the water. Leave sufficient room for displacement when entering to prevent water from spilling over the sides.
• Optional Cooling and Heating: When connected to a compatible Dynamic Cold Therapy chiller, adjust the desired water temperature according to the chiller's separate operating instructions. Available temperature settings, cooling rates, and connectivity features depend on the selected model.
• Safe Entry and Exit: Use the included Pacific Cedar entry step carefully. Enter the tub feet first, move slowly, and maintain controlled breathing throughout the session. Never practice breath-holding or hyperventilation in the water.
• Session Duration: Begin with moderate water temperatures and shorter immersion sessions, adjusting conservatively according to comfort and relevant medical guidance. Prolonged exposure to cold water can increase the risk of hypothermia.
• Using the Cover: Secure the insulated cover and locking latches whenever the plunge is not in use. Keep children and pets away from the tub and do not rely on a locking cover as a substitute for supervision.
• Water Chemistry: The manufacturer's manual recommends maintaining water pH between 7.2 and 7.8. Test water regularly and follow the manufacturer's guidance for compatible cleaning and water-treatment products.
• Water Replacement: For setups without external filtration or water treatment, the manufacturer's manual recommends replacing the water approximately every 3–5 days depending on usage. Systems equipped with a chiller still require regular water testing, cleaning, and periodic water changes.
• Cleaning the Stainless Steel Interior: Drain the tub and clean the interior with a soft cloth and an approved mild cleaning solution. Avoid abrasive brushes or chemicals that could damage the stainless steel finish or protective coating.
• Draining the Tub: Open the designated drain valve and direct water toward a suitable drainage area. Dispose of treated water in accordance with applicable local regulations.
• Storage and Maintenance: Empty, clean, and dry the tub before extended storage. Inspect the stainless steel surfaces, Pacific Cedar trim, cover, fittings, and drain regularly. Protect the unit from freezing conditions and prolonged direct sunlight as directed by the manufacturer.

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.
