Choosing a liner isn’t just a cosmetic decision—it’s a structural one. Because liners are simply plastic shells glued over your existing tub, they come with a host of built-in flaws:
The “Squish” Factor: Water inevitably leaks and accumulates between the old tub and the new liner. This creates a spongy, “squishy” feeling underfoot and leads to stagnant water odors.
A Breeding Ground for Mold: Trapped moisture is the perfect environment for dangerous mold and mildew. Once it starts, it is nearly impossible to remove without tearing out the entire liner.
Plumbing Complications: To accommodate the thickness of the liner, your drain and overflow pipelines must be extended, creating more points of potential failure.
Structural Failures: Because liners are made from a single sheet of plastic, the corners and edges are thin. Over time, everyday use leads to cracking and leaks.
Lost Space: A liner effectively “shrinks” your bathtub and your bathroom’s footprint by adding unnecessary bulk.
