Ruvati 21" x 17" Brenna Workstation Bathroom Sink Topmount - RVH5521ST

Brenna Collection: Topmount Workstation Bathroom Sink for RVs and Tiny Homes

The Ruvati RVH5521ST is the topmount version of the Brenna workstation bathroom sink — a drop-in design that installs directly into a countertop cutout with the rim sitting flush on the surface, no undermount clips required beneath the counter. At 21" x 17" exterior with an 18" x 12" interior basin and 5-1/2" bowl depth, it provides a generous footprint for a small-space bathroom sink. The integrated front-and-rear ledges support a sliding tray with board (RVA1543) and a colander (RVA1365), both included, which can be positioned over the basin to create usable counter space when the sink isn't in use. In an RV or tiny home where the vanity area may be the only flat surface in the bathroom, that reclaimed space is genuinely useful.

Sliding Tray, Colander, Pop-Up Drain, and Topmount Installation

The sliding tray with board covers the basin entirely when positioned across the ledge track, converting the sink footprint into a stable prep or storage surface. The colander slides independently along the same track for rinsing or holding small items. When the sink is needed, both accessories slide aside or lift out in seconds. The included stainless steel pop-up drain assembly is push-operated and sized to the standard 1.75" bathroom drain opening. Cutout templates and mounting clips are included for topmount installation. An optional full-coverage board (RVA1265, sold separately) is available for complete basin coverage.

Common Questions Answered

What is the practical difference between the topmount and undermount versions of the Brenna sink?

The topmount (RVH5521ST) drops into a countertop cutout with the rim resting on the surface — installation is straightforward and doesn't require access beneath the counter to secure mounting hardware. This makes it a better fit for RV and tiny home builds where the vanity cabinet may have limited under-counter access, or where the countertop material (laminate, for example) isn't well-suited to undermount installation. The undermount version (RVH6521ST) mounts from below for a seamless countertop surface with no rim above the counter — easier to wipe down, and a cleaner visual line. Both versions share the same 18" x 12" interior basin, 5-1/2" bowl depth, and workstation ledge system with the same included accessories. The choice comes down to your countertop material, cabinet access, and whether a flush countertop surface or simpler installation is the priority.
