How To Install a Roman Tub Faucet

Last Updated: October, 2021 | By JULIAN GILL

The Roman tub faucet is a deck mount faucet. This means that instead of having the handles in the wall, they are mounted on the tub, which makes them the perfect choice for stand-alone tubs. Installation of a roman tub faucet may vary depending on the manufacturer. For instance, Moen uses its own M-PACT system, which differs from Delta’s installation. Installation will also depend on whether it’s a trim kit or a faucet which requires the replacement of your plumbing. Knowing this, it’s crucial to pay attention to the instructions which came with your unit. The guide we provide is a general, step by step guide designed to give you an idea of the procedure.
