Welcome to Island Hot Tub, the original source for Chofu Wood-Fired Water Heaters, self contained electric heating systems, and soaking-tub accessories since 1985. We specialize in providing information and guidance to folks who want to create a soaking-tub, using one of our heating systems, and a tub of their choice: stock tanks, wooden tubs, recycled spas, large bathtubs, etc. 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 the commonly available items. Plus we provide information for sanitizing tubs without using harmful chemicals.


Chofu Wood-Burning Water Heater

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


Electric Heating Systems available soon

Island Hot Tub will soon be offering an exclusive self-contained 110v or 220v electric heating system that can be used with any tub – designed specifically for soaking tubs, either on-demand or continual-use. A special feature is a 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 tanks. 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.
