Liners are installed on top of your existing tub using tape and strong adhesives, simply covering up big issues in your bathroom. They can often crack or leak, causing issues with mold and mildew. Because of this, we do not offer bathtub liners. All of our solid surface acrylic products are naturally antimicrobial and installed by highly-trained professionals and master plumbers. We would remove your old tub, taking it all the ways down to the studs, and replace with an entirely new bath system.
