Q&A for How to Repair a Fiberglass Tub or Shower

Fiberglass tubs may crack if they’re poorly supported underneath, or if someone drops a heavy object in the tub and damages the fiberglass. They can also crack if the fiberglass is worn down by harsh, abrasive cleaners, such as bleach.

Fiberglass tubs are fairly delicate. With proper care, they will typically last about 10-15 years.

You need to handle stains in fiberglass tubs and showers carefully so that you don’t damage the delicate finish. Try letting the stain soak in castile soap for up to an hour, then rub the area with a soft cloth or sponge in a circular motion. Rinse the area thoroughly when you’re done. If that doesn’t work, you might be able to scrub the stain out with a baking soda paste and a soft cloth. For ultra-stubborn stains, acetone-based nail polish remover or turpentine may work. Let the solvent sit on the stain for up to an hour, then scrub the area with a soft nylon brush. Wipe it clean with a damp cloth or sponge.

A fiberglass tub itself will cost from $200-$500 at most. The labor cost is the other major factor and is hard to judge, so get quotes from several plumbers or, if the job is very simple and the existing plumbing is in good condition, you may be able to hire a handyman to do it and save some money. On average, expect to spend somewhere around $1000 total (tub plus installation), unless you have special requirements or bad plumbing.

You can paint bathtubs and tile yourself, but often the results won't look as good as a professional job (either to paint or replace the tile entirely). Painting may be a good option if you hate the current color and can't or would prefer not to replace the bathtub yet, just make sure you don't use regular paint, get a prepackaged kit with epoxies specifically made for painting bathtubs and tile.

Acrylic is a type of plastic.

There will be some tub and shower repair kits available at your local hardware stores, but you could also search online for the individual components and make your own kit, so to speak.

The drying time varies depending on the thickness and the proportions of resin, thickener, and hardener, as well as the temperature. Keep it warm and dry, and let it sit overnight at the least.

Urethane is the superior choice. A good mason yard sells urethane caulk that will work.

10 or 15 minutes with a good hair dryer should do it. Make sure the moisture level in the room is low, as well.

Any kind of bathroom cleaner should work just fine.
