How can I tell what material My bathtub is? If your tub has no give at all, then it’s steel or cast iron. Hold a magnet up to the tub; does it attract? If it’s magnetic, then it’s an enameled surface, but if it’s not magnetic, it’s porcelain.
What is the difference between porcelain and enamel bathtub? Enamel is quite understandable as Porcelain itself is an enamel coating, so the two have similar appearances. The primary difference is that Enamel covers steel or iron bathtub, meaning that the bathtub is magnetic while porcelain is not.
How can you tell the difference between a porcelain and ceramic tub? Look for chips in the glaze to identify ceramic tile.
Porcelain tiles are sometimes, but not always, glazed. Most high-quality porcelain tiles will have a consistent color that goes through the top, body, and bottom of the tile. Ceramic tiles, on the other hand, are nearly always glazed.
How do I know if my tub is enamel or acrylic? But how to tell the difference!?! Acrylic is pretty easy: If it looks plasticky, it’s an acrylic tub. If not, a simple test can help you to determine whether your tub is made of enamel or porcelain: put a magnet on it. If it sticks, the tub is enameled metal; if not, it’s porcelain.
