Introducing the “CUBOID” 304 Nano-Coated Stainless Steel Cold Plunge Tub—a bold, architectural take on modern cold therapy designed for luxury outdoor and indoor environments. With its clean lines, premium materials, and performance-driven engineering, the CUBOID elevates the cold plunge experience into a refined wellness ritual.
The exterior showcases a sophisticated combination of nano-coated stainless steel and finely crafted Pacific Cedar trim. The nano-coated stainless steel cabinet delivers a sleek, contemporary aesthetic while providing enhanced protection against outdoor weather elements, helping preserve the tub’s integrity and finish over time. Complementing this modern exterior, the Pacific Cedar trim introduces warmth and natural character. Known for its resilience and timeless beauty, Pacific Cedar enhances both durability and visual appeal, allowing the CUBOID to integrate seamlessly into upscale patios, poolside retreats, spa settings, or indoor wellness spaces.
Inside, the tub features a 304 nano-coated stainless steel interior that offers a smooth, polished surface with a distinctly premium feel. The 304-grade stainless steel construction is valued for its strength and resistance to corrosion, while the nano-coating adds an additional layer of refinement and protection. The result is a clean, hygienic, and visually striking interior that enhances every cold immersion session.
Thoughtfully designed with comfort in mind, the CUBOID’s spacious and ergonomic dimensions—55 inches in length, 32.5 inches in width, and 31.5 inches in height—provide ample room to sit back and fully immerse. Its generous interior allows for a relaxed, natural posture during cold therapy, making it ideal for post-workout recovery, inflammation reduction, improved circulation, and overall revitalization.
Ease of use and safety are integral to the design. A high-quality Pacific Cedar step is included to ensure stable and convenient entry and exit, blending functionality with cohesive design. When not in use, the custom-fitted cover with child safety latches provides added peace of mind, helping maintain water temperature while protecting the tub from debris and unauthorized access.
Built to uncompromising standards, the CUBOID Cold Plunge Tub reflects a commitment to craftsmanship and long-term performance. Backed by a one-year warranty, it offers confidence in both quality and durability—making it a powerful and elegant addition to any luxury wellness environment.

We prioritize quality in selecting the materials for our items, choosing premium fabrics and finishings that ensure durability, comfort, and timeless appeal.
We strive to process and ship all orders in a timely manner, working diligently to ensure that your items are on their way to you as soon as possible.
We recommend keeping the pH value of the water in the tub between 7.2 and 7.8. A pH value outside of this range can shorten the service life of the tub and cause irritation or damage to your skin. Any damage to the tub caused by too high or low pH value will not be covered by the manufacturer’s warranty. We suggest using a pH test kit to routinely test the water quality before using it.
It is important to keep the water in the tub clean. The optional Chiller does come with a built-in particle filter and ozonator to keep the water in the tub clean. Please see the Chiller User’s Manual for usage instructions. If you are not using an external filter and water cleaner, then we suggest the following:
Proper care and storage will prolong the service life of the tub. Before storing the tub, completely drain all water from the tub and wipe it down clean with a soft cotton cloth or towel. It is recommended to cover the tub and store it in a cool dry place.
