Product Overview
The Houzer CH-1800-1 Opus is an oval undermount bathroom sink made from 18-gauge T304 stainless steel. Its classic curved basin and lustrous satin finish provide a clean alternative to porcelain lavatory sinks while keeping the rim concealed beneath a compatible solid-surface countertop.
The sink measures approximately 17-3/4 inches long by 13-9/16 inches wide, with an interior bowl measuring about 15-1/2 inches by 11-3/8 inches and 6 inches deep. Houzer applies StoneGuard undercoating over a sound-absorbing pad to help reduce vibration and water noise. This model uses a standard 1-1/2-inch drain opening and does not include an overflow opening.
The drain assembly is sold separately. Houzer supplies mounting and installation components and identifies the sink for a minimum 21-inch cabinet or bathroom vanity. Confirm the countertop construction, reveal style, faucet reach, non-overflow drain, and plumbing clearance before fabrication.
