Ruvati RVG2018 17" Square Granite Composite Undermount Bar Prep Sink

Square Format, 20" Cabinet, 8-1/2" Deep

The RVG2018 is a nearly square undermount bar sink — 17-1/3" wide by 17-1/3" front-to-back — with a 20" minimum base cabinet requirement. Despite the compact footprint, the bowl runs 8-1/2" deep, giving it more usable volume than the exterior dimensions suggest. The square format suits corner cabinet installations and narrow island cutouts where a rectangular sink would require more linear cabinet space. A matching color strainer drain assembly is included — white with the Arctic White Matte finish, black with the Black finish.

Where the Square Format Makes Sense

Most undermount bar sinks are rectangular, which works well in a standard linear cabinet run but can be awkward in corner or angled installations. The RVG2018's near-square footprint — 15-3/4" x 15-3/4" inside — fits naturally into corner base cabinets, diagonal island cutouts, and tight wet bar configurations where a longer rectangular basin would either overhang the cabinet or require a wider run than the space allows. The epiGranite construction — 80% crushed natural granite manufactured in Italy — delivers the same heat resistance up to 536°F, non-porous stain resistance, and through-body color as the larger models. The sink is cUPC certified and tested by IAPMO to meet all US and Canadian plumbing standards.

Common Questions Answered

Does the square shape affect how the sink drains or how accessories fit?

The square interior doesn't affect drainage — the standard 3.5" drain opening works the same way as any other undermount sink and is compatible with garbage disposal units. Where the square format does make a practical difference is in how the basin feels to use: the equal width and depth means there's no narrow end to work around, which some people find more natural for rinsing glassware or washing produce. Standard bar sink accessories — grids, strainers, and similar items — are typically sized for rectangular basins, so confirm dimensions before purchasing any add-ons.
