Get matched with top bathtub liner or shower surround installers and replacers in your area

A bathtub liner is a custom, one-piece shell that slips over your existing tub to hide cracks, stains, and chips. Most are molded from tough acrylic or PVC and can include a matching wall surround for a complete facelift. When a pro bonds the liner in place, you get a watertight seal, a fresh look, and an added layer of safety—all without tearing out the old tub.

After a tech measures your tub and orders a made-to-fit shell, installation takes a day. The installer cleans the surface, applies industrial-grade adhesive, and positions the liner in place. They trim the edges, tighten the drain, and run a smooth bead of silicone caulk to lock out moisture. A quick plumbing check wraps things up, leaving you with a ready-to-use tub by the next morning.

You can pick preset sizes or order a liner molded to your tub’s exact shape, then choose from dozens of colors, patterns, and finishes to match—or refresh—your bathroom. A pro trims and fits the shell on-site, so every contour lines up and accessories like grab bars or shelving land exactly where you want them.

If the liner’s material accepts a fresh coating, a professional can sand it, apply epoxy, and restore the shine in six hours for $480. Swapping in a brand-new liner runs $800 to $1,000 and takes a day or less. Refinishing is the wallet-friendly route when the shell is structurally sound, but it won’t last as long as starting over with new acrylic.

Most liners last three to five years. High-quality acrylic, a snug professional fit, and routine cleaning help you reach the upper end of that range. If moisture seeps behind the shell, mold and odors can shorten its life, so keep an eye out for loose caulk or soft spots and call a professional if you spot trouble early.
