A bathtub liner can provide a new look for your old bathtub surface. You can get standard liners at the home improvement stores and install them with ease. This type of liner will be installed directly over the top of your existing bathtub and will basically cover up the existing tub. Follow the simple steps below to effectively install a bathtub liner.

Step 1 - Prepare the Bathtub

To begin, remove anything that is on the surface of the bathtub so that the liner will stick well. To do this, pour some denatured alcohol onto the surface of the tub. Use your rag to scrub the surface with the alcohol. This should help remove any soap scum or oil that has been left on the surface.

Step 2 - Remove the Knobs

In order to get in the bathtub liner in place, you will need to take off the knobs from the fixtures in the bathtub. Unscrew them and set them to the side so that you can replace them later. Some people take this opportunity to replace the faucet. If that is the case, take it off and you will put a new one on later.

Step 3 - Apply Adhesive

The next thing that you need to do is apply the adhesive to the old bathtub—a special adhesive that is designed for liners. Spread the adhesive evenly over the surface of the old bathtub. Make sure that every bit of it is covered so that you do not have any gaps in coverage when the new liner is installed.

Step 4 - Apply Sealer

In addition to adhesive, you may also need to install a sealer. This is a substance that will go around the outside edge of the liner to prevent moisture or anything else from getting up under the liner.

Step 5 - Put the Liner in Place

The liner will be a large, single piece of acrylic or PVC. Please it on the bathtub, and if necessary, cut to fit with a utility knife. Once the liner is in place, press it down to the bathtub surface so that all of the air underneath is removed.
