Elkay Residential CMR43221 Triple Bowl Drop-in Sink 43x22

Product Description

The ELKAY RESIDENTIAL CMR43221 is a triple bowl drop-in kitchen sink constructed from 20-gauge Type 304 stainless steel. It measures 43 inches x 22 inches overall and features three rectangular bowls arranged for multitasking workflows. The two main bowls each measure 13.5 inches x 18 inches with a 6.875-inch depth, while the smaller center bowl measures 10 inches x 12 inches. A 3.5-inch center drain is standard across all bowls. Sound-deadening pads are applied to the underside to reduce noise and vibration during use. This sink is installed by plumbers or experienced tradespeople in residential kitchen countertop cutouts.

The CMR43221 is suited for residential kitchen installations where a multi-bowl layout is required for tasks such as washing, soaking, rinsing, and food prep staging. The drop-in design seats into a countertop cutout and is secured with U-channel mounting clips that come pre-installed in the channel. A minimum cabinet width of 48 inches is required. The sink is compatible with countertops up to 0.75 inches thick using the included hardware. Straight sidewalls produce a flat bottom interior that maximizes usable basin space and simplifies cleaning. Manufactured in the USA.
