The Cost of Repairing and Refinishing a Cracked Shower Floor

Fiberglass Patch

• The DIY option for fixing fiberglass is a fiberglass patch. The patch inlays on the bottom of the tub or shower and can be cut to fit the entire bottom surface. Once the fiberglass is measured, an adhesive is applied and the inlay is laid and pressed into place. The inlay must cure for 48 hours before the tub can be used. Fiberglass patches cost on average $135, at the time of publication.

Professional Repair

• During a professional repair, the repairmen will inspect the substrate and treat the bottom of the shower pan for greater support and stability. Next, the repair person injects patching material into the crack and then smooths the surface so that the shower looks new. A repair of this type costs on average between $250 and $300.

New Shower

• As a point of reference when considering the cost of patching and refinishing, a new shower encasement costs an average of $1,000 to $1,500. This cost does not include replacing the water barrier or the installation equipment. This pricing also doesn't reflect professional installation, since most homeowners will not have the know-how to tackle this project.

Shower Foundation

• Regardless of how you repair the shower, there is an underlying problem that must be addressed. The reason that the crack occurred is typically due to an uneven subfloor. To fully address this problem, you'll need to remove the bottom boards and liners and inspect the substrate. If it is uneven, you will have to add shims as necessary to support the shower and prevent future cracking.
