Tub Surround Installation

Performing a tub surround installation is a project that should only take one or two days, and will greatly enhance the look of your bathroom. Tub surrounds are often in need of replacing because they are susceptible to water damage. However, when installed properly, they can last for many years.

Before choosing a tub surround that fits your budget and your needs, consider the following:

• Plastic tub surround kits range between $60 and $500, with an average price of $150
• The more expensive versions are made from pressed fiberglass, which lasts much longer than plastic
• Starter kits are usually made from ABS or PVC panels that are thin and don't stand against a wall without additional support. You will spend more time installing these cheaper versions
• Mid-priced thermal-plastic units often have formed features, such as soap dishes and shelves. These versions are worth the extra money for durability and looks
• Top dollar pressed fiberglass kits are thick, rigid and extremely durable
• A smooth texture, low-luster surface is best for hiding water spots and soap scum
• Tub surrounds come in three or five piece kits. If you have well-formed walls that are straight and true, the three piece kit should be fine
• Five-piece kits are better for walls that are crooked or not perfectly square

If you are experienced at DIY home improvement a tub surround installation should be no problem. You will need some specialty tools, so check that you have everything you need before you get started:

• Tub surround kit
• Caulking gun
• Adhesive
• Mildew-resistant caulk
• Carpenter's level
• Tape measure
• Utility knife
• Allen wrenches
• Pliers, screwdriver
• Green drywall (if your walls are damaged)
• Drywall compound (if you need to install drywall)

First, remove the faucet trim and spout, as well as the showerhead. Then remove the existing tub surround. Once you have peeled it off the wall check for any damage to the drywall. Chances are there has been some water leakage over the years and some parts of the wall may need to be patched, replaced or skim coated.

Remove any damaged tiles and cut out damp or wet drywall. Replace these areas with green drywall, which is designed for damp environments. If you have to replace the drywall, sand and finish it and then paint with a latex primer. Make sure your walls are as level as possible before installing the tub surround.

When installing a tub surround, make certain everything remains level with a vertical reference line. Using a carpenter's level, draw a plumb line that runs from the outside corners of your bathtub. Then follow these steps to install your tub surround:

1. Install the corner pieces first by dry fitting each panel and adjusting the fit of each according to how square your walls are. You might need to trim the pieces if your walls are really crooked
2. Spread a bead of adhesive around the perimeter of the first panel about one inch away from the adhesive tape that comes already on the panel. Remove the paper from the adhesive and set the panel in place
3. Repeat this process with the other corner panel
4. After the corners are installed measure the distance between them and determine the center point. Then, measure the center panel to find its center point and mark that point
5. Apply adhesive to the back of the center panel, remove the backing from the tape and center the panel on the wall. Press the panel to the wall, making certain that it is flush with the corners
6. Attach the other panels in the same manner

Before installing the final end panel, you will need to cut holes for the plumbing fixtures. This requires careful measurements and precise cutting.

First, mark the locations of your fixtures on your panel, then use a 1-inch spade bit to cut the holes for the spout. You might need to use a larger Saber saw to cut the hole for the faucet.

After the holes are cut, apply the adhesive, remove the backing from the tape and install the panel.

Although tub surround panels are already waterproof, it is important to seal the gaps between the panels and wall around the perimeter with a latex adhesive caulk. For some of the smaller joints and the vertical seams, try using a small tube of bathroom silicone caulk for a better looking job.

Finally, install your fixtures, let everything dry for at least 24 hours and your tub surround is ready to go!
