Ruvati epiCube RVG1631 31" Topmount Workstation Kitchen Sink with Dual Ledges

epiCube RVG1631 — 31" Topmount Workstation Sink, Dual Ledges, Two Finishes The RVG1631 is a 31" topmount workstation kitchen sink from Ruvati's epiCube collection, available in Arctic White Matte and Black. What sets the epiCube apart from other Ruvati workstation sinks is the dual ledge system — one ledge runs along the top of the bowl rim, and a second ledge runs along the bottom interior of the bowl, giving the included accessories two distinct working positions. The gray composite cutting board slides along either ledge and features dish rack slots for draining washed items directly into the sink. The patented foldable drying rack, constructed of stainless steel bars with a flexible silicone frame, stores flat and deploys across the top ledge for air-drying. Made in Italy from 80% crushed natural granite, each finish is colored all the way through. Minimum 36" base cabinet required. Granite Composite Construction — Extreme Durability, Non-Porous Surface The 80% natural granite content delivers exceptional durability and heat resistance up to 536°F. The proprietary 20% resin treatment creates a completely non-porous surface that naturally resists stains, bacteria, and household chemicals. The thick solid construction provides natural sound dampening, and the gently rounded interior corners make cleaning straightforward. Topmount installation with included cutout templates and mounting clips.

The top ledge runs along the rim of the sink bowl and is the primary working position — this is where the cutting board sits when you're prepping food over the sink, and where the foldable drying rack deploys for air-drying dishes. Working at the top ledge keeps everything at countertop height, which is comfortable for extended prep tasks. The bottom ledge runs along the interior floor of the bowl and provides a lower working position — useful for tasks where you want the cutting board partially submerged or positioned lower, such as washing produce directly in the bowl or using the board as a colander platform. The cutting board is sized to fit both ledges, so you can move it between positions depending on the task. Most users will work primarily from the top ledge and use the bottom ledge for specific tasks or as a resting position when the top ledge is occupied by the drying rack.
