Whirlpool Bathtubs
Whirlpool bathtubs have increased their popularity in the past years and are now becoming the largest expanse and most bathroom remodeling projects. These bathtubs are made from acrylic and cast-iron, the most common being acrylic.

Acrylic can be formed and shaped easier than cast-iron, and seems like it would be cheaper to manufacture, but I'm not entirely sure for one reason, some of these bathtubs are over $8,000.

The bathtub you're looking at to the right is Jacuzzi bathtub Model: EY70959 and is one of these bathtubs. Don't think you can't afford a whirlpool bathtub if you truly desire one, they can be found for around $500.
