I guess I am stupid. I just finished trying to clean my three piece tub unit and almost cried. I have had the unit for about 8 years and did what most consumers do..not complain. The upper wall pieces are beautiful. The tub unit is all stained. This started about 9 months after owning it. I have not used abrasive cleaners and have thoroughly rinsed after each cleaning. The finish is off the tub unit on the side that the shower curtain is not. I use a Municipal water supply, so there is no excuse for this. I also had two cracks show up in the tub and had to purchase Mirolin's tub repair. All it is, is kitchen caulking. I now have two rubber patches staring at me every time I get into this tub. I paid over $1200 for this piece of crap. My brother does home renovations and he told me that if he knew that I was going to buy this tub he would have told me not to. He uses a much cheaper unit that holds up very well over time. Please complain, don't be like me and wait too long. Don't purchase their products..please..save yourself the headache.
