Compact Oval Cup Sink

The Orion CS1-6x3x4 is a black polyethylene sink designed for wall-mounted installation. Its oval bowl measures 6 by 3 inches with a 4-inch depth, providing a compact washing station. The material resists corrosion and impact, suiting utility rooms, workshops or secondary bathrooms where a small basin is required.

Drop-In Mounting Flexibility

The unit installs as a drop-in sink, allowing above-counter or below-counter placement to match the countertop design. A 1-1/2 inch drain opening accepts standard waste fittings without special adapters. Polyethylene construction keeps weight low, reducing structural demands on the supporting wall or cabinet.

Replaces Metal or Ceramic Utility Basins

This sink replaces heavier metal or ceramic utility basins where chemical resistance and lighter handling are priorities. The jump is worthwhile when the installation calls for a non-conductive, dent-resistant surface in a tight footprint. It is not suited for applications requiring ADA-compliant clearances or larger bowl capacities.

Questions about this item

Will the 1-1/2 in drain opening handle continuous flow without backing up?

The 1-1/2 inch drain opening is sized for standard laboratory cup-sink waste lines; sustained flow capacity depends on the connected plumbing and trap configuration.

Does the polyethylene bowl transmit vibration or heat when water runs all day?

Polyethylene damps vibration and does not conduct heat like metal, so the bowl stays quiet and near ambient temperature during extended use.

What mounting hardware and countertop cut-out are required for the drop-in installation?

The sink drops into a cut-out matching the 7 in by 3-7/8 in overall dimensions; clips or silicone sealant are typically supplied by the installer.
