Bathtubs can be manufactured from a wide range of materials and in a variety of forms and styles. Whether they are hand-carved from a single block of Marquina taupe marble, handmade from fiberglass-reinforced concrete, or manufactured from an acrylic-based solid surface, they all aim to create a bathing environment in which to linger.

Freestanding basins can become a bathroom centerpiece, so it is important to look for practical options that offer style, comfort, and durability. Made with long-lasting and high-quality materials and finishes, the four freestanding bathtubs below feature clean lines and organic shapes in an effort to embrace the minimalist look.
