Why is acrylic used for bathtubs?

Acrylic is used for bathtubs due to its lightweight nature, which makes installation easier compared to heavier materials like cast iron or stone. It can be molded into various shapes and sizes, allowing for versatile designs. Additionally, acrylic has a smooth, non-porous surface that is easy to clean and maintain, and it retains heat well, providing a comfortable bathing experience. Its affordability and wide range of colors also contribute to its popularity in bathroom fixtures.
