Product review (4 stars): Work as designed
These work well and do what they are meant to do. We bought the all white ones and they match the white Kohler tub (Underscore 66"x32") exactly.
We bought our tub through a local retailer and were not told that we would need to purchase the trim package separately.
They do the job and I love my tub, but it does seem insane to pay hundreds of dollars for pieces of plastic!
