Description

The Vanta Cold Plunge Pro was built for one job — making cold immersion a daily, no-fuss part of your life. A powerful chiller pulls water down to 39°F and holds it there. The integrated filtration and ozone keep it clean. The shell is insulated, weather-rated, and made to look like it belongs in your space, not behind it.

Plug it in, fill it with a garden hose, and you're three hours from your first cold morning. No plumbing, no electrician, no app required.

Cold and heat, working in tandem.

Two well-studied tools. Different jobs. Better days.

Cold Plunge

Faster recoveryCold immersion is linked to reduced muscle soreness after intense training.
Sharper focusA short plunge releases dopamine and norepinephrine for hours of clarity.
Better sleepLowering core temperature in the morning can support deeper sleep at night.
Stress resilienceRepeated cold exposure trains the nervous system to stay calm under pressure.

Cold Plunges

Sauna

Cardiovascular supportHeat sessions raise heart rate similar to moderate exercise — a workout for your circulation.
Deeper relaxationHeat shifts the body into a parasympathetic state — slower breath, calmer mind.
Muscle and joint reliefIncreased blood flow to soft tissue eases stiffness and post-training tension.
Cellular renewalHeat triggers heat-shock proteins, the body's repair signal for damaged cells.
