Perfect Drain eliminates the gap around the drain, reducing the chance that bacteria and grime can build up in and around the sink’s drain area. Users can install a Perfect Drain sink with the drain assembly or pick an InSinkErator disposer with QuickLock mounting. This product works exclusively with InSinkErator food waste disposers. Perfect Drain integrates seamlessly into the bottom of select top mount and undermount sink models, as well as in both single and double bowl configurations. The Perfect Drain innovation is offered on most popular sink models, and has an MSRP range from $598 to $1,536. These costs include all of the drain parts needed.
