How to Choose the Right Tub

When considering the difference between acrylic and fiberglass tubs, start with durability. Acrylic tubs generally last longer due to their robust nature, while fiberglass is prone to scratches and can degrade more quickly over time, especially with hard use. I suggest going with acrylic if you plan to use the tub frequently. It saves you money in replacement costs down the line.

Next, evaluate weight. Acrylic tubs are much lighter, averaging around 60 to 100 pounds, making them easier to install and less of a strain on your bathroom structure. In contrast, fiberglass can weigh as little as 50 pounds, but its lighter composition can compromise long-term durability. Consider this if installation ease is your primary concern.

Lastly, think about maintenance. Acrylic bathtubs are far easier to clean than fiberglass ones because they don’t stain or hold grime as easily, allowing you to maintain a cleaner bathroom with less effort. If you're busy and want a low-maintenance option, acrylic is a better choice.
