Professional Square Acrylic Cold Plunge Tub – G4
A Powerful Recovery Tool for Serious Performance
Cold immersion has become one of the most trusted recovery methods used by athletes, trainers, and high-performing professionals. The G4 Professional Square Acrylic Cold Plunge System makes it possible to bring that same level of recovery into your home, gym, or wellness space—without the inconvenience of traditional ice baths.
Instead of constantly buying ice and waiting for the water to cool, this all-in-one plunge system maintains the temperature automatically. When you’re ready to use it, your cold plunge is already prepared.
Simple, reliable, and built for people who take recovery seriously.
A Complete Cold Plunge System
The G4 is designed as a fully integrated system, which means everything needed for cold immersion is built directly into the unit.
Inside the plunge you’ll find:
• A powerful built-in chiller
• Advanced filtration
• Water purification
• Digital temperature control
This design eliminates the need for external equipment or complicated setups. Once the tub is filled and plugged in, the system manages the temperature and water quality on its own.
It’s a much cleaner and easier way to maintain a cold plunge compared to traditional ice baths.
Consistent, Controlled Temperatures
One of the biggest problems with ice baths is inconsistency. The water warms up quickly, and every session requires new ice.
The G4 solves that problem with an integrated cooling system that can chill water to very low temperatures—around 32°F (0°C) when needed. Once you set your preferred temperature, the system keeps it there.
This means every session delivers the same reliable cold immersion experience, whether you’re using it after workouts, sauna sessions, or simply as part of a daily wellness routine.
Smart Control From Your Phone
The G4 also includes Wi-Fi connectivity, allowing you to control the system through a mobile app.
From your phone you can:
• Adjust the water temperature
• Turn the system on or off
• Schedule cooling cycles
• Monitor system performance
Many owners like to start cooling the water before a workout so the plunge is ready the moment they finish training.
Clean Water With Minimal Maintenance
Keeping the water clean is just as important as keeping it cold. The G4 uses a multi-stage filtration system along with ozone purification to help maintain clear, hygienic water.
The filtration continuously circulates the water while the purification system helps prevent buildup and contaminants. This reduces the need for frequent water changes and keeps the plunge ready for regular use.
Built to Fit Modern Wellness Spaces
The square acrylic design gives the G4 a clean, modern look that works well in a variety of environments.
It’s a popular choice for:
• Home gyms
• Sauna rooms
• Recovery spaces
• Training facilities
• Wellness studios
Rather than looking like bulky equipment, the G4 feels like a natural part of a dedicated wellness environment.
Why People Use Cold Plunges
Cold immersion has become widely used because of the way it supports recovery and overall wellness.
Regular cold exposure may help with:
• Reducing muscle soreness after training
• Supporting faster recovery between workouts
• Improving circulation
• Increasing alertness and mental clarity
• Building mental resilience
Many people also find that the discipline of stepping into cold water carries over into other areas of life.
