Undermounts are drop-ins destined for floor-level installation. Flooring, such as tile, covers the lip of the tub. Corner tubs are variations on the alcove and drop-in designs. Their large, squarish proportions are conducive to dual bathing. Freestanding tubs feature a sculpted bathing bowl on a solid base or a cradle.

Freestanding options include luxurious styles like clawfoot tubs, while corner tubs offer plenty of extra space with added features like jets and whirlpools. On the other hand, small bathtubs like drop-in and alcove options may be more suitable when space is tight, and a walk-in tub might be helpful for folks with limited mobility.
