Qtoo Single Hole Sensor Tap System

Touchless sink-mounted tap system in marine-grade stainless steel. Includes top-mounted sensor tap, concealed Flexbox control, and optional drain and siphon components.

The Qtoo Sink-Mounted Sensor Tap offers streamlined, top-mounted functionality with integrated infrared (IR) sensor technology. Its fixed spout and smooth cylindrical form make it ideal for commercial environments requiring high hygiene standards and long-term durability. The unit pairs with the Qtoo Flexbox (QSF01), which houses all electronic components for simplified installation and servicing.

Designed in collaboration with Hans Thyge & Co., Qtoo sensor taps combine expressive Danish form with technical excellence. Made from certified marine-grade stainless steel, Qtoo products are NSF/ANSI 61-compliant, lead-free, and built to withstand commercial use and harsh cleaning conditions. All sensor models include optional cleaning mode, automatic rinse cycles (deactivated by default), and extended battery life ranging from 4.6 to 8.4 years.
