Alcove Tubs: This is the standard three-wall install with a finished front apron built into the tub. A shower setup is often included with an alcove tub and is often called a tub/shower unit.
Drop-In or Under-Mount Tubs: These tubs need to be framed in place, usually with four knee walls surrounding the tub. Drop-in models have finished rims and sit on top of the deck, under-mounts are usually flush with the finished deck.
Freestanding Tubs: A freestanding tub is self-supporting with all sides finished. Because they can be placed just about anywhere in the bathroom, freestanding tubs are often used as a decorative focal point.
Corner Tub: If you absolutely need to put a bathtub in a corner, these specialized tubs have cornered the market!
