Roman tub faucets are usually deck-mounted, medium-to-large in size, with high-arc spouts and 2-3 handles for hot and cold water. Compared to standard wall-mounted tub faucets, Roman tub faucets usually do not connect to an overhead showerhead. Paired with large soaking tubs, they reflect Roman architectural aesthetics. They often feature high-flow rates for faster filling.

Roman tub faucets require a tub with a large deck and flat, wide rims that have 3-5 mounting holes. Roman tub faucets are usually deck-mounted on the tub itself or on a nearby platform. They can also have a transfer valve (diverter) used to direct water to a hand shower.

Rough-in valve

There is also an internal component called the rough-in valve, which connects the supply water lines to the faucet.

Be cautious: rough-in valves are only compatible with systems from the same manufacturer as the faucet you want to install.

Because they contain many internal components, they require a removable maintenance panel for easy access.

Spout

As for spouts, the typical style of a Roman tub faucet is a high-arc design. It's one of the defining aesthetic features of Roman tub faucets. However, today there are other stylistic options like low-arc or flat spouts.
