Ruvati 20" x 14" Ariaso Nano-PVD Ramp Bathroom Sink Undermount - RVH6140

Ariaso Collection: Nano-PVD Color in an Undermount Ramp Bathroom Sink

The Ruvati RVH6140 is a ramp-format undermount bathroom sink from the Ariaso collection — a design where the interior floor slopes continuously from 3/4" at the shallow front edge to 6" at the deep rear, creating a distinctive angled profile that channels water directly toward the rear-positioned drain. Available in Gunmetal Black (nano-PVD) or Brushed Stainless Steel, the 20" x 14" footprint fits a 22" minimum cabinet and installs as a standard undermount with cutout templates and mounting clips included. The nano-PVD process bonds color directly to the 16-gauge T-304 stainless steel at the molecular level, producing a matte, fingerprint-resistant finish that is genuinely resistant to wear, abrasion, and peeling. A matching color pop-up drain assembly is included.

Undermount Installation, Sloped Interior, and Matching Pop-Up Drain

The undermount format keeps the countertop surface completely uninterrupted — no rim above the counter, easier to wipe down, and a cleaner visual line than a topmount or semi-recessed installation. The sloped interior is both a design statement and a functional feature: the continuous grade from front to back means water moves toward the drain naturally rather than pooling on a flat basin floor. The matching color pop-up drain assembly completes the look, with the drain cap finished in the same Gunmetal Black or brushed stainless as the sink body. The RVH6140 is suitable for both residential and commercial bathroom applications.

Common Questions Answered

What is a ramp sink, and is the sloped interior practical for everyday bathroom use?

A ramp sink has a continuously sloped interior floor rather than a flat basin — the front edge is shallow (3/4" in the RVH6140) and the floor descends toward the rear where the drain is positioned, reaching 6" at the deepest point. The slope serves two purposes: it creates a visually distinctive profile that reads as a design element rather than a standard basin, and it ensures water drains completely toward the rear without pooling on a flat floor. For everyday bathroom use — handwashing, face washing, brushing teeth — the ramp format works naturally: water flows away from you toward the drain as you use the sink. The shallow front edge also makes the sink feel more open and accessible than a uniformly deep basin, which can be an advantage in compact bathrooms where the vanity is close to the user.
