Product Overview
The Houzer CHT-1800-1 Opus Series bathroom sink gives homeowners, remodelers, and plumbing professionals a durable stainless steel option for a drop-in vanity installation. Its oval shape and lustrous satin finish provide a clean, understated look that works well in powder rooms, guest bathrooms, utility spaces, and compact commercial lavatories. The sink is made from 18-gauge T-304 stainless steel, helping it stand up to everyday use while remaining easier to handle than many heavier sink materials during installation.
This model is designed for topmount installation and fits a minimum 21-inch cabinet or vanity base. The outer sink measures 17-3/4 inches long by 13-9/16 inches wide by 6 inches deep, while the interior bowl measures 15-1/2 inches long by 11-3/8 inches wide by 6 inches deep. A rear-positioned standard 1-1/2-inch drain opening helps preserve usable bowl space. The CHT-1800-1 is the without-overflow version, so it should be paired with a compatible non-overflow drain assembly. Mounting clips are included, and Houzer's StoneGuard undercoating with a sound-absorbing pad helps reduce noise during normal use. For a replacement or new vanity project that calls for a compact stainless steel lavatory sink, this model offers straightforward sizing, familiar drop-in installation, and confirmed Houzer construction details.
