What Is a Bathtub Liner

A bathtub liner is a thin acrylic sheet that fits over an existing bathtub. If the tub liner fits perfectly into an existing tub and is appropriately installed, it can last as long as a new tub. However, it may crack if there is a problem with the shape or mounting.

The bathtub liner temporarily modifies the bathtub. It can hide unsightly cracks and discolorations and is one of the most economical options for bathroom refurbishment.

Problems that can be fixed with a bathtub liner

Theoretically, a new tub can last up to 20 years, but usually, the tub will not be in its original condition after ten years. What goes wrong with a bathtub depends on the material of the bathtub.

  • Fade finish and spider crack

Fiberglass tubs can fade and crack spiders. The material is thin plastic, so it is brittle and porous.

  • Scratch

Acrylic bathtubs are made of petrochemicals and resin. It may crack if washed with an abrasive solution.

  • Chips and rust

Steel tubs that are porcelain enamel tend to chip or rust over time. The same is true for cast iron tubs that are porcelain enamel-coated.

If chips, rust, cracks, and scratches are tiny and are localized to a particular area of ​​the bathtub, home improvement products may be able to spot and repair that area. However, if the problem is widespread, consider a bathtub liner or other option. If you do nothing, the problem will only escalate.

Benefits of bathtub liner

1. A tub liner is a mid-range solution.

At first glance, it sounded like a tub liner would cost about the maximum amount of getting a brand new tub-like cast-iron bathtub. But that was before considering the installation.

An average bathtub liner costs around $850-$1,000, depending on the market price. There are two styles of materials to make tub liners: Poly Vinyl Chloride (PVC) plastic and composite made from 85% Acrylonitrile Butadiene Styrene (ABS) and 15% acrylic. ABS acrylic is more expensive.

Preparing to pay for the installation of a shower liner will cost about the identical because of the bath liner itself. And if you would like a bathtub surround, that may add to the cost.

The cost of a brand-new bathtub, a like cast-iron tub, is about the same as that of a bathtub liner.

After you can consider everything involved in buying a new tub, notice that getting a bathtub liner would be considerably cheaper once factored in the installation.).

2.Some bathtub liners are durable.

Bathtub liners, especially those made of composite ABS acrylic, are designed to last a long time. ABS acrylic is thicker and more durable than PVC plastic bath liners. The bathroom liner material is non-porous and should not be yellow or faded. In addition, the ABS acrylic liner is highly scratch resistant.

In theory, a tub liner can last as long as decades! The tub liner will last longer than the refinish, usually a short repair. You can only assume that the tub is shiny and looks new for only a year or two. (Still, Miracle Method, a refinishing company, claims that the refinishing process will take 10 to 15 years.)

3. Installing is quick and easy

● You can call a professional plumber. Then answer a few questions and take them to your local dealer.

● A local dealer sent an expert to your house to measure the tub.

● The specialist came back a month or two with a bath insert that fits on the tub perfectly.

● The liner can install in one day.

Another significant advantage is that much fewer toxic chemicals and smoke are released while installing the bathtub liner compared to repainting the bathtub.

Disadvantages of tub liner

Therefore, bath liners have some drawbacks, including the fact that water can leak through the bath liner. The disadvantages are:

1. Risk of improper or inadequate installation of the liner

Choose a reputable local tub liner franchise. While the state-owned company manufactures the bathtub liner, the local franchise company measures the existing bathtub and then installs the liner.

Why? It is because you must ensure that all tasks, such as measurement, manufacturing, and installation, are performed correctly.

A liner that does not fit snugly or is not installed correctly can tear.

2. If the liner is torn, some mold may form.

Although uncommon, a spongy sensation or stink when entering a bathtub can be the first sign of a bathtub liner burst. Hairline cracks can also allow water to seep between the liner and the tub.

● Undiscovered problem

A problem like scratch may not be detected for a long time, leading to mold and mildews. Not only is this usually a problem for your bathroom, but it is also bad for the air quality. As you may know, some forms of mold are toxic.

● Incompatible drainage pipes and overflow drainage pipes

Inadequate tub and overflow drain installation can also allow water to seep between the liner and the tub. For this reason, it is crucial to check the references of your local retailer. You need to ensure as much as possible that the people who measure and install your tub liner are likely to do the perfect job.

3.You can’t go back to the original bathtub.

The tub liner does not repair rust, scratches, or cracks on the tub. Instead, a bath liner covers the problem. You can get the old tub back if you like the tub insert. It is because the glue that glues the liner to the tub is so strong that removing the tub liner destroys the finish of the old tub.

If there is a problem with the liner and it is still under warranty, the company will come and fix the problem or replace the liner with a new one.

Here’s why you should reconsider getting a bathtub liner

Bathtub liners can save you money on tub replacement and refurbishment, but there are some facts you must know before deciding on a bathtub liner, not refinishing or reglazing.

1.The liner does not solve the underlying problems.

The liner covers only the surface of the bathtub. Sure, scratches, cracks, and chips are covered, but it doesn’t hide the fact that you may need to repair your furniture. The longer you leave the liner on, the more likely it is to worsen the problem.

2.Liner catches water

The trapped water is the worst. It can grow mold and even carry large amounts of truly harmful bacteria. The problem with using bath liners is that water mostly gets between the liner and the tub, and mold and mold can further discolor the surface.

3.The liner does not give a good feeling.

The lining does not give the tub the smooth, untouched feel that the finish of the finished tub gives. Many people who use liners are dissatisfied with the spongy feel of the surface when it comes in contact with the liner, and some need help finding a stable foothold.

4.Liner is costly

Contrary to popular belief, bathtub liners are more expensive than bathtub refinishing. In addition, trying to apply it yourself can be confusing and very tedious.


So is the bath liner good? The bath liner is suitable if you still need to modify the bathroom and have the money for a new tub and installation. The only condition is to make sure you are purchasing from a reputable local dealer and try to get a warranty. In this way, you minimize risk and make sound investments.
