Elkay Residential DRKAD222050FR4 Drop-in Classroom Sink

Product Description

The ELKAY RESIDENTIAL DRKAD222050FR4 is a single bowl drop-in classroom sink manufactured from 18-gauge Type 304 stainless steel. It measures 22 inches by 19.5 inches overall, with a rectangular bowl that is 13.5 inches long, 16 inches wide, and 4.875 inches deep. The rear center drain placement maximizes usable cabinet space below the sink. Sound Guard technology with large sound-deadening pads reduces operational noise. The scratch-resistant finish holds up under heavy daily use, and deeper surface marks can be addressed with an Elkay restoration kit. Built and assembled in the USA, this sink meets ADA compliance requirements for accessible installations in educational and institutional settings.

This sink is designed for drop-in installation into countertops up to 0.75 inches thick. It is sized for educational environments such as K-12 classrooms, labs, and similar institutional spaces where accessibility and durability are required. The minimum cabinet size for installation is 27 inches. The drain opening accommodates a standard 3.5-inch drain fitting, and the sink is disposal ready. It is equally suited to light commercial applications where an ADA-compliant stainless steel sink is specified.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC and local plumbing code requirements. Shut off the water supply and disconnect existing drain lines before beginning any sink replacement work. Drop-in installation requires a precise countertop cutout per the manufacturer-specified dimensions; verify cutout measurements against the sink template before cutting. Do not overtighten mounting clips, as this can distort the sink rim or damage laminate and solid-surface countertop materials.
