A bathtub liner is a thin sheet covering that will hide cracks, stains, and other imperfections. It is a quick solution to a problem that will eventually need to be fixed by remodeling or refinishing. A bathtub liner prevents you from having to remove and replace your current tub and it can last for several years. Acrylic liners are most commonly used in bathtubs due to their durability.
Determine if your bathtub really needs a liner. If the bathtub has several cracks, stains, discoloration, and mildew then you will need a liner. Before installing the new liner, the old or original bathtub liner will need to be removed. This could cause additional damage to the bathtub. Therefore, you will only want to get another liner if the bathtub is in bad enough shape to replace the liner, but in good enough shape to keep.
Go to a local hardware store. Most major hardware stores such as Home Depot and Lowes will sell and install bathtub liners.
Look online for a bathtub liner. There are several companies that sell bathtub liners online such as beautiful finishes and miracle method. You can install the liner yourself or pay a professional to install the liner.
Choose a liner that matches the color of the bathtub or the decor of the bathroom.
