Factors affecting the cost of a bathtub liner include whether the owner wants just the tub relined or the tub and walls, the liner materials, any required customization, and the materials the owner selects. Adding a bathtub liner is usually less expensive than replacing the tub, but more expensive than reglazing it.
Professionals install most liners, although some companies make liners for homeowner installation. Generally, professional installation provides a higher-quality finished product with a longer life expectancy. Do-it-yourself installations that crack or leak retain water between the liner and tub and encourage the growth of mold, mildew and bacteria, which can in turn cause health issues.
As of 2015, most homeowners spend between $1,610 and $3,755 for a bathtub liner, with an average cost of $2,521. The very lowest reported price is $800, and the highest $5,000. Liners are available in plastic, acrylic or PVC, and come in a variety of colors. Installing the liner eliminates the need to tear out walls and plumbing when updating the bathroom.
Installing a bathtub liner restores shine and helps to modernize an outdated tub. A liner is a possible solution to an older tub in a color the owner no longer finds attractive for the bathroom.
