Grate & Waste is a simple device designed to improve aesthetics at minimal cost. This product can be used as both an internal and an external drainage solution. When used internally it is coupled to a P-trap, most commonly found in showers. If used externally it can be coupled directly into either 40mm or 50mm plumbing pipe and is most commonly used as a drainage point on balconies and patios. Some gas installation suppliers even use the 50mm Grate & Waste as air vents in walls to allow movement of air through walls in case of a gas leak. Grate & Wastes are available in three stylish grate finishes: stainless steel square hole design, stainless steel round hole design or a solid white ABS grate. Choose the waste size you require in the finish that matches your aesthetic appeal.
