Why RiverMode
RiverMode™ is a high-flow circulation system that continuously moves water throughout the tub, creating a steady, river-like current instead of still water. This matters because in a static plunge, your body quickly forms a thin layer of warmth around the skin—reducing the intensity of the cold. By constantly replacing that warmed layer with fresh cold water, RiverMode™ maintains consistent exposure across the entire body. The result is a more effective physiological response—greater activation of the nervous system, more uniform cooling, and a deeper, more complete cold immersion experience without needing lower temperatures.
Featured Testimonials
“If you want to test your mental strength, BlueCube is the one to do it in. RiverMode is next level.”
“BlueCube is unmatched in the quality of their plunge. I have owned another well known brand and it doesn’t come close to the product BlueCube has put out. My plunge holds exact temperatures even on days of 110 degrees. Filtration system is amazing and I don’t have to add chemicals to the water to keep it clean. Cant say enough good things about the customer service I received and the white glove service setting up my plunge at my house.”
“I love my cold plunge and use it everyday. Every step of the way was easy. From the questions to the delivery, as well as the customer service after. The plunge in itself is incredibly high-quality and like no other cold plunge I’ve ever seen or experienced. I love the 3 speed river mode. Amazing experience and amazing people there. Strongly recommend.”

Our Cold Plunge Frequently Asked Questions
What is a cold plunge and how is it different from an ice bath?
A cold plunge is a temperature-controlled system that continuously chills, filters, and sanitizes water. Unlike traditional ice baths, it maintains a consistent temperature and clean water without the need for ice.
What are the benefits of cold plunging?
Research suggests benefits may include improved circulation, reduced inflammation, faster recovery, and increased alertness through norepinephrine release.
Can I combine sauna and cold plunge?
Yes. Contrast therapy alternates heat and cold (e.g., sauna → plunge) to improve circulation and recovery.
What features should I look for in a cold plunge?
Key features include precise temperature control, strong filtration, durable materials, high flow rate, and reliable warranty/support.
What materials are used in BlueCube cold plunges?
BlueCube units use commercial-grade PVC plumbing, Iwaki pumps, Balboa chillers, marine-grade Baltic birch, Line-X coating, and American-made stainless steel, carbon fiber, or acrylic tubs.
Where can I install a cold plunge?
Cold plunges can be installed indoors or outdoors on a level surface with proper electrical access.
What are the electrical requirements?
Most systems require a dedicated 110/120V 20-amp circuit.
