Acrylic Bathtubs
Acrylic bathtubs are made from a material called polymethyl methacrylate (PMMA), a type of plastic that is lightweight and flexible. Acrylic bathtubs are popular because they come in a wide range of styles and sizes, making them a versatile choice for any bathroom. They are also resistant to rust and discoloration, which means they maintain their luxurious appearance for years to come. Acrylic bathtubs are typically less expensive than cast iron options, which makes them a popular choice for homeowners on a budget.
Some of the best applications for acrylic bathtubs include free-standing options, which can add a modern and sleek look to your bathroom. They also work well for smaller bathrooms where a lighter and more compact bathtub is needed. However, if you’re looking for a bathtub with more durability and resistance to damage, cast iron may be a better choice.
III. Cast Iron Bathtubs
Cast iron bathtubs have been a popular choice for homeowners for over a century. They are known for their durability, strength, and longevity. The material used in cast iron bathtubs is molten pig iron, which is then poured into a mold and coated with enamel. This coating gives the bathtub a shiny, polished finish.
