Product Overview
The Houzer CRTO-1620-1 Opus is a round conical topmount bathroom sink made from 18-gauge T304 stainless steel. Its tapered bowl and lustrous satin finish create a contemporary focal point for powder rooms, guest baths, and compact vanity installations, while the drop-in rim supports installation from above a compatible 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 beneath the bowl to help reduce vibration and water noise. This model includes an overflow opening and overflow assembly and uses a standard 1-1/2-inch lavatory drain opening.
The drain assembly is sold separately. Houzer supplies installation components and identifies the sink for a minimum 21-inch cabinet or bathroom vanity. Confirm the countertop opening, rim support, faucet reach, overflow-compatible drain, and available cabinet clearance before installation.
