Kooru Cold Plunge Tub

The Art of the Cold Plunge.
Passionately handcrafted in San Diego from sustainably sourced redwood, the Kooru Cold Plunge Tub is a statement piece as much as a wellness ritual — arriving fully assembled and ready to transform your recovery.

Why You'll Love It

• Shou Sugi Ban burning — an ancient Japanese wood-charring technique that enhances durability and reveals stunning grain depth
• Adjustable temperature control with a programmable chiller — dial in your perfect plunge temperature
• Natural ozone water purification (O3) keeps your plunge clean without chemicals or harmful byproducts
• Plugs into a standard 110V outlet — no complex installation required
• Every tub is hand-selected, hand-fired, and hand-sanded — a truly bespoke wellness investment

How to Use

• Set your desired temperature via the programmable chiller before your session
• Plunge for your preferred duration — cold water immersion is a hormetic stressor that makes you stronger
• Replace the ozone filter every 1–2 months for optimal water purity
