Clawfoot bathtubs, by definition, are bathtubs that have clawfoot legs/feet holding them above the ground.  Clawfoot tub styles date back to Ancient Rome, Greece, and Egypt, and they have remained popular.  They are typically freestanding and elevated, making them relatively easy to clean but somewhat space consuming, unless they are situated directly against a wall.  They have faded in popularity over the past half-century, but their classic style has made them grow in popularity in the last decade as people have tried to find ways to design unique, stylish bathrooms.  However, studies have proven that clawfoot bathtubs do not add to the resale value of your home as much as a contemporary whirlpool bathtub, even though they often cost more, so buyer beware.
