Welcome to Island Hot Tub, the original source for Chofu wood fired hot tub heaters, weather protected electric hot tub heating systems, and soaking-tub accessories since 1985. We specialize in providing information and guidance to folk who want to create a DIY hot tub using: stock tanks, wooden tubs, recycled spas, or large bathtubs. You provide the tub – we provide the heater, materials, and instructions.

We also supply hard-to-find components and materials for tub-builders, and resources for locating commonly available items. In addition, we provide information for sanitizing tubs without using harmful chemicals.


Chofu Wood-Burning Hot Tub Heater

Island Hot Tub is the exclusive North American importer and distributor of the Chofu stove, a precision-built, high-efficiency hot tub heater, designed specifically for hot tubs. The Chofu circulates water without electricity and without noise, using the principle of “thermosiphon” or heat convection. This feature allows you to enjoy a simple and affordable hot tub in any location.


Electric Heating Systems available soon

Island Hot Tub will soon be offering an exclusive weather protected 110v or 220v electric heating system that can be used with any tub – designed specifically for hot tubs, either on-demand or continual-use. A special feature is the quiet circulating pump that doesn’t intrude on the soaking tub experience.


Soaking Tub Pioneers

Since 1985 we have pioneered the concept of demand-heated, low-volume soaking tubs, including stock tank hot tubs. We are dedicated to educating people about the benefits and affordability of soaking tubs, and making outdoor hot water soaking part of a normal healthy lifestyle.
