Bathtub paint refers to a type of paint that is specifically designed to be used on bathtubs and other bathroom fixtures. It can be applied directly to the bathtub surface to provide a durable and waterproof coating that can rejuvenate an old or worn-out bathtub. Bathtub paint is typically a two-part epoxy paint that cures and hardens to create a long-lasting finish that resists chipping and peeling. It is available in a variety of colors and finishes, and can be used to update the look of your bathtub without having to replace it.
