Product Highlights
Spacious 148-Gallon Oval Design
At 148 gallons, this is one of the largest inflatable cold plunge options available for home use. The oval shape allows users to fully extend their body for a more complete immersion experience compared to standard round tubs.
7-Layer Reinforced Insulation
The multi-layer wall construction retains cold temperatures more effectively than single-layer alternatives, reducing chiller workload and keeping your water at the right temperature throughout your session.
1/3 HP Chiller
The included chiller actively cools the water to your preferred temperature and maintains it throughout use. No need to source or manage bags of ice between sessions.
Advanced Filtration System
A continuously circulating filtration system traps fine particles and keeps water clear. The filter cartridge is easy to clean or replace, making routine maintenance quick and straightforward.
Insulated Cover Included
The insulated cover reduces heat gain between sessions and helps keep the water clean when the tub is not in use, extending the time between water changes.
Complete Kit, Ready to Use
