Archimedes would've approved of these overflow bathtubs!
These whirlpool overflow bathtubs by German manufacturer Käsch is unusual for two main reasons. First, they are set level on the floor. Second, they are designed so that the water level is right to the rim of the tubs. These units have a surrounding outer ring that captures water as it overflows, and circulates it back to the tub.
Käsch has created its overflow whirlpool bathtub series in round, oval, square and rectangular shapes to fit your bathroom.
