I am trying to find quartz for showerpan from the larger quartz manufacurers - Cambria, Caesarstone, Zodiac etc. but just cannot do. driving me crazy... have found some independents that manufacture. I think quartz has more 'life' in it appearance wise -- not as much as granite but more than corian and the other acrylics. So...I am left to Swanstone which has acrylics and some natural ingredients ---Swanstone makes showerbase and wall surrounds. .. any advice/experience with this product in the bath? Cleaning? stain? crazing/cracks? What about your kitchen experiences. Thanks.
