• Another definition of Roman bathtubs simply calls any center-fill bathtub (having the faucet in the middle of a long side, versus on the end) a Roman bathtub.
• Generally, Roman tubs are deeper than the average American bathtub and designed only as a soaking bathtub, with no shower or jets built in.
• Some bathtub manufacturers also refer to Roman bathtubs as free standing, that is, above ground, resting on legs or a pedestal. This particular style is usually oversized and catered more to the high-end market.
