Dynamic Cold Therapy Cuboid Cold Plunge – 50" & 55"
A modern cuboid cold plunge built for a clean, permanent recovery setup. The Dynamic Cold Therapy 50 & 55 Cold Plunge pairs a black powder-coated exterior with Pacific Cedar trim and your choice of a PVC interior or nano-coated 304 stainless steel interior. Three configurations let you choose the material and size that best fits your space.
Chiller sold separately. Each tub is pre-configured for connection to a compatible Dynamic Cold Therapy cooling/heating system, so you can start with the tub alone or build out a temperature-controlled setup.
Choose Your Configuration
50" Standard / PVC — DCT-S-050-PL-34: The lower-priced configuration pairs the same modern cuboid format with a durable PVC interior.
50" Standard / 304 Stainless Steel — DCT-S-050-NS-34: The standard-size cuboid upgraded with a nano-coated 304 stainless steel interior for a more premium finish.
55" XL / 304 Stainless Steel — DCT-S-055-NS-34: Adds five inches of exterior length and additional interior room while retaining the nano-coated 304 stainless steel interior.
Purpose-Built Cuboid Design
Unlike the taller barrel-style plunges, the Cuboid uses a lower rectangular profile and a flat interior floor rather than an integrated bench. The result is a more bathtub-like immersion position with generous usable length, especially in the 55-inch XL configuration.
Powder-Coated Exterior with Pacific Cedar Trim
The clean black exterior gives the Cuboid a contemporary look, while Pacific Cedar trim softens the design and ties it into dedicated wellness rooms, home gyms, patios, and recovery spaces. A matching Pacific Cedar step is included for easier entry and exit.
Chiller-Ready Plumbing
Each configuration is pre-connected for an optional Dynamic Cold Therapy chiller with 3/4-inch inlet and outlet connections. The included plumbing hardware features a pair of 3/4-inch ball valves and quick-connect fittings, plus a 1-inch drain valve for straightforward draining.
Included Cover & Access Step
A matching Pacific Cedar step and insulated spa cover with locking child-safety latches are included with the tub, giving you a more complete setup straight out of the box.
Why Choose the Dynamic Cold Therapy Cuboid?
The Cuboid is a strong choice for someone who prefers a contemporary rectangular plunge over a traditional barrel shape. The 50-inch model keeps the footprint compact, while the 55-inch XL gives you additional room to stretch out. With PVC and stainless steel interior options, you can prioritize either value or a more premium interior finish without changing the overall design language.
