Product Overview
The Houzer CR-1620-1 Opus is a round conical undermount bathroom sink made from 18-gauge T304 stainless steel. Its tapered bowl and lustrous satin finish create a clean contemporary profile for powder rooms, guest baths, and compact vanity installations while placing the sink rim below a compatible solid-surface countertop.
The sink measures approximately 16-3/4 inches in overall diameter with a 14-3/8-inch interior bowl diameter and a 6-1/4-inch bowl depth. Houzer applies an undercoating and sound-absorbing material beneath the bowl to help reduce vibration and water noise. This model has a standard 1-1/2-inch drain opening and does not include an overflow opening.
A drain assembly is sold separately. Houzer supplies the cutout template, fasteners, and installation instructions and identifies the sink for a minimum 21-inch cabinet or bathroom vanity. Confirm the countertop construction, reveal style, faucet reach, drain assembly, and available cabinet clearance before fabrication.
