Colorstone is a South Australian business that prides itself in manufacturing high-quality gully sinks for external use. The sinks were first designed and manufactured by a plumber in 1991 as he could see the need in the market for a durable and easy to fit outdoor sink.
The business was bought by a commercial builder in 1999 who had used the product on a large number of building projects and could see the demand for it.
The Colorstone gully sinks are available through all leading plumbing and hardware outlets.
