What Causes a Fiberglass Tub to Crack?

Fiberglass tubs often crack from excessive pressure on the surface, poor maintenance, and improper fixture installation. Repairs vary based on the severity of the defect. For example, stress cracks resulting from heavy surface impact are easy to repair, but hairline cracks and holes stemming from poor maintenance cost hundreds to restore.

3 Common Causes of Fiberglass Tub Cracks

Several issues can cause your fiberglass tub to crack, but they generally boil down to:

1. Heavy Impact

Dropping heavy objects will leave stress cracks on your fiberglass tub. Accidents often happen to those who place decorative items like statuettes and scented candles on their tub surround. Luckily, shallow stress cracks require minimal repairs.

If a senior relative or disabled household member uses your walk-in tub regularly, get rid of all knick-knacks and decorative items. Yes, they create a cozy atmosphere. However, these hazards increase the risk of accidents for your mobility-impaired loved ones.

2. Use of Improper Cleaning Supplies

Consistently using the same harmful, abrasive cleaners on your fiberglass tub will gradually weaken the surface, thus leaving it prone to cracks. Plus, harsh chemicals cause glossy fiberglass to fade. Remember: Fiberglass tubs have a fragile white, brilliant surface.

Fortunately, you can avoid these issues by using natural cleaners. Instead of bleach or generic chemicals, use vinegar and baking soda. Mix these two, then apply on the tub with a clean sponge and microfiber cloth.

3. Poor Installation

Walk-in tubs require additional support underneath to withstand daily usage. Otherwise, the surface would crack. 

These issues often appear in cheap DIY tubs, so avoid them. In fact, a DIY approach has fewer upfront fees, but it also poses a significant risk to the user. It’s best to call a professional if you do not have prior experience.
