Bathtub Liner. Bathtub linings, also called bathtub liners, plastic bath liners or tub inserts are usually made by vacuum forming either an oil or acrylic plastic sheet that is pressed then molded into a closed mold by using strong vacuum. The purpose of a bathtub liner is to prevent water from leaking out of the tub. The bathtub liner prevents slippage which could occur if there is a crack in the bathtub liner. It also prevents the bathtub from soaking through a small gap near the rim of the bathtub. The tub may leak slightly with a bathtub liner but this is not generally a major concern.
Having the right mold for the bathtub liner is very important for the liner to properly fit. Most bathtub linings have a polyethylene sheet that is rolled onto a large plastic tube called a mandrel. The plastic tube allows the bathtub liner to be placed into the drain opening and has the ability to stay in place as it is pushed down the drain. The rollers on the bathtub liner allow it to stay in place as it is pushed down the drain.
Depending on the size and type of tubs you have will determine the shape and material of the bathtub liner you need. Shower tubs often have a round drain opening. Plastic bathtub liners can be used to line these and they work just as well. For handicap showers, fiberglass bathtub liner is used, which allows the liner to be smaller than standard bathtub liner.

The types of materials are polyethylene, ABS acrylic, fiberglass and the thermoplastic pvc. Each of these materials come with advantages and disadvantages. With fiberglass, there is the potential for cracking under certain conditions but the durability is said to be excellent. Acrylic also has a good reputation, although it does dent easily and must be re-pointed. PVC is said to be the best choice for commercial applications, however, the installation requirements are very stringent and may not be suited for residential installation.
Professional bath fitter will be able to determine the right material and proper installation method for your bathtub liner installation. The average homeowner will not have this level of expertise and can potentially end up damaging their plumbing or having problems with the fiberglass tub after installation. Most professional installers will recommend a combination of acrylic and fiberglass tub liner for optimum results. Having an experienced plumber perform the installation is advised so that the bath fitter will be able to advise on the best method of application for your drainage setup.
There are many benefits to having the bathtub liner installed professionally. Most installation professionals will be able to offer expert advice concerning which bathtub liner would be the best choice based on your plumbing design. If the bathtub liner is to be used as a component of a new construction project the installation will ensure that the installation meets all codes and specifications. By using a bathtub liner with the installation, it will ensure that the bathtub meets the requirements of the plumbing for a seamless finish.
Most bathtub linings are relatively easy to care for and maintain. A simple coat of marine varnish or similar finish should suffice to keep the bathtub looking good for many years. Fiberglass is said to be one of the most durable materials available for refinishing bathtubs and it is recommended that bathtub liners be replaced every ten years or so. Many companies that offer bathtub liner installation are known to offer a lifetime warranty on their products. The majority of these companies will also replace the liners if they are damaged or not as appealing as the originally installed.
Bathtub liner installation is a relatively simple process but it does require some patience and attention to detail. The adhesive used in the installation should be kept clean and should never be reused on the same area on two different tubs. Any cracks in the bathtub liner will need to be repaired immediately to avoid water damage to the room it is in. Small cracks may be fixed by a patching compound while larger cracks will have to be filled with a special resin that will prevent any additional water from getting into the cracks.
