MIRROR-LIKE FINISH FROM DESIGNER ACRYLIC , Years of Cleanliness and Sparkle, Equally important to us as the material construction was the finish on the tub. If you think about it, bathtubs are permanent fixtures that must withstand varied uses, chemicals, and (perhaps most importantly) years of indirect and direct daytime sunlight that shines in through windows. So our goal was to create an anti-microbial, impervious finish that is not only high-gloss, clean, and bright-white when new, but high-gloss, clean, and bright-white when not-so-new.
