Qtoo Bathtub Waste Drain with Overflow

Seamlessly integrated with overflow functionality and foot-bounce drainage for effortless water management, the Qtoo Bathtub Waste is available in two configurations:

• Without Water Filler – A standard configuration where the overflow functions only as a safety drain. Water enters the tub via a separate spout or wall-mounted filler.
• With Integrated Water Filler – A modern, minimal design where the tub fills through the overflow itself. This eliminates the need for a visible spout and delivers water directly through the overflow cover.

This system is part of the Qtoo collection and can be paired with other items from the Knud Holscher Collection by d line, including the touchless soap dispenser, touchless paper dispenser, and the manual paper towel dispenser, for a cohesive and efficient bathroom design.
