Step-in tubs are deeper from tub rim to tub bottom than standard tubs, so the tub bottom is closer to the floor. A lift-out door allows pets to step directly into the tub. These tubs include our patented Hair Catching System*. They measure 48” x 24”, 52” x 24”, or 60” x 27”.These versatile 14-gauge stainless steel, fully welded tubs will comfortably accommodate any breed of dog from giants to miniatures.The built-in, high-capacity Hair Catching System* on these step-in tub models helps keep pet hair out of drains. This patented design is built into the tub model at the time of construction, and consists of an integral drain trough 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 out of drain. Special tuck-under feature ensures ALL water must flow through the Hair Catching Basket before going down the drain.The extra-wide door opening is close enough to the floor in these deep tubs that larger dogs can simply step in. A very sturdy stainless steel Canine Step Stool with a non-slip surface is included, to give older dogs and dogs with physical disabilities an extra assist in the tub.The Elevating Platform System** makes it easy to bathe smaller animals. Simply lift the platform, turn it 90 degrees and put it in place to position your pet at a level comfortable for both of you. The elevated platforms can also serve as a drying/brushing station.And there will be no down time with these tubs because they don’t wear out – ever!*US Patent #7080608​**US Patent #8220417
