I wanted to replace our plastic oval sink in the bathroom with a stainless-steel sink. I measured the sink and it measures 12 ¼ side to side and 15 5/8 front to back however that size doesn’t exist. Prime Time says the sink is 15X12 can’t seem to find that size either. I keep finding tons of 13X12 stainless steel sinks along with 16 3/4" X 11 3/4". Has anyone had experience with replacing this size sink were do measure to get the exact fit?
