When your bathtub or shower floor flexes, sags, or feels spongy underfoot, the problem goes deeper than the surface. Heritage Coatings' structural repair services address the root cause — whether it's a deteriorated subfloor, a cracked fiberglass pan, or a void beneath the tub.
A flexing tub or shower floor isn't just uncomfortable — it's a sign of structural failure that will get worse over time. Continued use can lead to cracking, water leaks, subfloor rot, and eventually a complete failure that requires emergency replacement.
A flexing tub floor usually means there are voids beneath the fiberglass or acrylic pan — often caused by settling, moisture damage to the subfloor, or improper original installation. Foam injection fills these voids and eliminates the flex.
In most cases, yes. We use structural floor inlays and foam injection to restore structural integrity without removing the tub. This saves thousands compared to full replacement.
Structural repairs vary based on the severity and type of damage. Foam injection for minor flex starts lower, while floor inlays and subfloor work cost more. Contact us for a free assessment and quote.
Yes. We frequently combine structural repair with full refinishing in a single visit, restoring both the structural integrity and the surface appearance of your tub or shower.

Everything About Structural Tub & Shower Repair
We use proven structural repair techniques to restore your tub or shower to solid, safe condition without the cost and disruption of a full replacement. Foam injection fills voids beneath fiberglass and acrylic pans, eliminating flex and restoring solid footing. Structural floor inlays reinforce cracked or weakened surfaces from above.
