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 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.
