Porcelain vs Fiberglass Tubs: What’s the Difference?

Porcelain over cast-iron tubs are heavy, cool to the touch, and last decades. Refinishing porcelain is straightforward with a proper etch.

Fiberglass tubs are lighter, warmer, and can flex over time. Refinishing may require structural fiberglass repair beneath the coat.

Both types refinish beautifully. The key is matching the prep and primer to the substrate.
