5 Tips for Installing a Fiberglass Tub Surround 5 Tips for Installing a Fiberglass Tub Surround

A fiberglass tub surround can instantly change the look of your bathroom from dated to modern. The installation process is straightforward, but there are a few things you can do to make the process go as smoothly as possible. Here are some tips to consider when installing a fiberglass tub surround.

Protect the Bathtub

It's important to take the steps to protect your bathtub from damage during the removal of the old surround and the installation of the new surround. Chips in the enamel of a traditional tub will eventually wear away, create a hole, and cause the tub to leak. New fiberglass tubs are very difficult to fix once they're scratched or chipped because they can't be re-finished like traditional tubs. A heavy drop cloth, like the type used to protect surfaces when painting, works the best. Other choices are cardboard boxes strategically placed over the tub. With cardboard, you won't be able to get all surfaces covered. Several old sheets will also work, but they won't be as thick as a drop cloth and won't provide the same level of protection. Tarps like the kind used for camping are also a good option.

Begin Installation From a Corner

Begin installing the fiberglass tub surround from a corner and work your way out. It may be tempting to start at a single end and work your way around the tub. The problem with this method is that you run the risk of the corners not fitting properly. It's much easier to cut any excess fiberglass from the edges.

Mark Holes for Fixtures

Create a cardboard template of where you would like the fixtures to be placed. Use a cardboard piece the size of the panel. Measure the location of the fixtures on the wall and duplicate their position on the cardboard piece. Cut holes in the cardboard, making sure they're just the right size. If they're too big, you're going to damaged the fiberglass since there will be too much room around the fixtures. If the holes are too small, you'll have the difficult task of trying to make the openings larger while the fiberglass in on the wall. Use the template as a guide while you cut the holes into the fiberglass with a jigsaw. Try to lay the fiberglass panel flat as you do this. If that isn't an option, cut the fiberglass while it's upright but keep it away from the tub.

Dry-Fit Panels Before Installation

Make sure you have all the parts to the tub surround and that each panel is in good shape before applying the adhesive. Position each panel without glue where it should be to make sure there are no gaps and that the panels are plumb.

Fix Damaged Drywall

After removing of the old tub surround and before installing of the new fiberglass tub surround, take a close look at the drywall. If you had tiles before, grout may have worn away, allowing moisture behind the wall. Replace any sections of drywall as necessary. Replace entire panels of basic drywall with green board drywall, which has a moisture-resistant paper covering. Fiberglass tub surrounds don't leak that easily, but if moisture gets behind the surround and the wall, green board will reduce mildew and mold growth.
