Elkay Residential CMR43224 Triple Bowl Drop-in Kitchen Sink

Product Description

The ELKAY RESIDENTIAL CMR43224 is a triple bowl drop-in kitchen sink constructed from 20-gauge Type 304 stainless steel. It measures 43 inches x 22 inches x 7 inches overall and features three rectangular bowls with straight sidewalls, providing flat-bottom space for stacking, soaking, and washing. The primary bowl measures 13.5 inches x 18 inches with a 6.875-inch depth. A second bowl measures 10 inches x 12 inches with a 5-inch depth. Each bowl uses a 3.5-inch center drain compatible with standard garbage disposals. Four pre-drilled faucet holes allow flexible faucet and sprayer configurations. Sound-deadening pads reduce vibration and operational noise. Manufactured in the USA.

This sink is designed for drop-in installation in residential kitchen countertops. The U-channel mounting system allows installation clips to be positioned inside the channel before the sink is set, simplifying the process for plumbers and installers. The countertop cutout dimension is 42-3/8 inches x 21-3/8 inches, and the sink accommodates countertops up to 3/4 inches thick. A minimum cabinet width of 48 inches is required. With three distinct bowls, this sink supports simultaneous multitasking such as food prep, rinsing, and soaking during high-volume kitchen use.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC guidelines. Shut off the water supply and disconnect any existing drain connections before removing an old sink. Verify the cabinet width meets the 48-inch minimum requirement and confirm the countertop cutout dimensions before setting the sink. Do not exceed the countertop thickness rating of 3/4 inches, as this may prevent a proper seal with the mounting clips.
