Kooru Cold Plunge Tub

Handcrafted in San Diego from selected redwood, each tub is hand-selected board by board and finished using Shou Sugi Ban — the centuries-old Japanese technique of charring wood to protect and darken the grain. The result is a cold plunge that looks like furniture, not equipment, and comes fully set up on delivery.

Right For You If…

• You want a cold plunge that reads as a piece of handcrafted furniture, not utilitarian equipment
• You have a standard 110V outlet available and want a simple, low-maintenance setup rather than a complex install
• You value visible craftsmanship and are comfortable with the subtle natural variation that comes with handmade wood pieces

What Makes It Worth It

• Shou Sugi Ban charred-wood finish — a traditional preservation technique that also deepens the wood's natural grain and color
• Runs on a standard 110V outlet — no specialized electrical work required (GFCI or grounded outlet recommended per local code)
• Ozone-based water sanitation — treats water without added chemicals or byproducts, requiring only periodic filter changes (roughly every 1–2 months)
• 1/4 HP chiller with 950 GPH pump — maintains consistent water temperature
• High-density polyurethane tub interior — durable, easy-to-maintain basin within the wood exterior
• Comes fully assembled — arrives ready to use rather than requiring on-site build
