A built-in, high-capacity Hair Catching System* on certain tub models helps keep pet hair out of drains.
This patented design is built into the tub at the time of construction, and consists of an integral drain recess, spanning the entire width (front to back) of the tub on the drain end, with a lift-out stainless steel fine-mesh basket that screens hair and debris before it reaches the drain. Special tuck-under feature ensures ALL water must flow through the Hair Catching Basket before going down the drain.
