1000mm Stainless Steel DUH Sluice Sink with Drainer (Slop Hopper) – Hospital Disposal Unit
Washware Product Code: H-DUH
HBN designation: DUH
The H-DUH is our current-generation 1000mm stainless steel DUH sluice sink, combining a wall-mounted sluice disposal bowl with an integral drainer/work surface. Featuring an improved flush pipe connection design for easier installation, standard configurations are held in UK stock for fast delivery, typically within 1–2 working days.
Designed for hospitals, care homes, nursing homes and other healthcare environments, the H-DUH provides the hygienic waste disposal function of a sluice sink or slop hopper together with additional stainless steel working and draining space.
Manufactured from high-quality Grade 304 stainless steel, the unit provides a durable and easy-to-clean solution for demanding sluice rooms and dirty utility rooms.
The H-DUH is manufactured to meet the relevant requirements of HBN 00-10 Part C: Sanitary Assemblies, which superseded the former HTM 64 guidance.
What Is a DUH Sluice Sink?
A DUH is a wall-mounted sluice disposal unit with an integral drainer/work surface.
Unlike a standard DU sluice sink, which provides a compact disposal bowl within an approximately 600mm-wide unit, the DUH extends the stainless steel top to provide additional working and draining space.
The H-DUH measures 1000mm x 600mm and is available with the sluice bowl positioned at either end of the unit, allowing the handing to be selected to suit the room layout and existing services.
If you require a separate sink bowl as well as the sluice disposal bowl and drainer, a DUHS combined sluice unit should be considered instead.

DU or DUH – Which Do I Need?
Choose a DU sluice sink where you require a compact wall-mounted disposal unit without an extended work surface.
Choose a DUH sluice sink where you require the same type of flushing disposal bowl but also need additional stainless steel drainer/work surface alongside it.
If you require a separate sink bowl in addition to the sluice disposal bowl and drainer, consider a DUHS combined sluice sink, sink bowl and drainer.
