Cold. Heat. Contrast.
Professional-grade cold plunge pools and high-performance saunas designed for commercial wellness facilities, gyms, and recovery studios. From 37 degrees to 230 degrees, Plunge delivers the complete contrast therapy experience.
Our Mission
Plunge was founded on a simple belief: that recovery deserves the same level of investment as strength, cardio, and nutrition. Born in Venice, California, Plunge set out to make professional-grade cold water therapy and contrast therapy accessible to every fitness and wellness facility — not just elite training centers.

Venice, California — Recovery Innovation Since 2020
Plunge cold plunge systems maintain precise temperatures down to 37 degrees with integrated 20-micron filtration and ozone sanitation. The fiberglass-reinforced acrylic shells, powerful built-in chillers, and insulated covers deliver a pristine, consistent cold therapy experience that reduces inflammation, boosts circulation, and accelerates muscle recovery.
Plunge saunas are hand-crafted in California and engineered to reach 230 degrees — the optimal temperature for deep sweat, detoxification, and cardiovascular conditioning. Ergonomic slanted backrests, flip-up benches for stretching, and full app control via the Plunge app make every session effortless and effective.
Every Plunge system connects to the Plunge app via WiFi, allowing remote session scheduling, temperature control, and guided cold plunge protocols. Members can start their sauna or verify their cold plunge is ready before they even walk into the recovery room. This is recovery technology built for the modern facility.

High-end health clubs differentiate themselves with dedicated recovery rooms featuring Plunge cold plunges and saunas. Members expect premium amenities — contrast therapy is becoming the standard, not the luxury. The Plunge app integration lets members schedule sessions remotely, enhancing the digital experience.

Boutique studios focused on holistic wellness incorporate the Plunge Pod and Sauna Mini for their compact footprints. The 20-minute setup and plug-and-play design let studios add recovery offerings without expensive renovations. The Plunge Pod at 87 gallons fits where larger tubs cannot.

Forward-thinking corporations add Plunge All-In systems to their on-site wellness centers as a competitive employee benefit. The app-controlled sessions let employees schedule recovery breaks during the workday, reducing stress, improving focus, and demonstrating genuine investment in workforce wellbeing.

Physical therapy clinics use Plunge cold plunge systems for patient recovery protocols. The precise temperature control and consistent sanitation support clinical-grade standards. The All-In Gen 2 with its built-in chiller and filtration system meets the hygiene requirements of medical environments while delivering therapeutic cold exposure benefits.

Luxury hotels and resorts install Plunge systems in their spa and wellness areas to offer guests world-class recovery experiences. The plug-and-play design means minimal installation disruption, while the app control and premium aesthetics align with the expectations of discerning travelers seeking cutting-edge wellness amenities.

The Plunge All-In is the full-size cold plunge system designed for commercial facilities with high member traffic. It features a built-in chiller, filtration, and ozone sanitation in a self-contained unit.

Yes. OptiFit provides full Plunge delivery, installation, and ongoing service. Cold plunge and sauna installation requires specific plumbing, electrical, and ventilation considerations. Our team handles site assessment, utility coordination, equipment placement, and staff training. We also provide water chemistry guidance and maintenance programs to ensure optimal sanitation and performance. The typical commercial installation is completed in 1-2 days.
Cold plunge therapy reduces inflammation, boosts circulation, accelerates muscle recovery, and triggers the release of norepinephrine for improved focus and mood. Sauna therapy promotes deep sweating for detoxification, improves cardiovascular conditioning, and enhances muscle relaxation. Contrast therapy — alternating between cold plunge and sauna — provides the combined benefits of both while stimulating the vascular system. Research from institutions like Finland's University of Jyväskylä supports the cardiovascular and metabolic benefits of regular sauna use.
Plunge offers a 1-year commercial warranty on all cold plunge and sauna systems. The warranty covers the chiller, filtration system, electrical components, and structural integrity. The fiberglass-reinforced acrylic shells and sealed systems are designed for continuous commercial use. OptiFit coordinates all warranty and service support directly with Plunge on behalf of our clients, including replacement parts and repair services.
