Deck mounted tub faucets have an alias of rim-mounted faucets. Typically, pre-drilled holes are required to install these tub faucets. These faucets are fitted on the rim of your bathtub; actually, it requires a flat surface.
These faucets also accept underfloor water supply lines. If you don’t have underfloor access, you can use flexible water supply lines to connect the faucet to the tub.
Generally, deck-mounted bathtub faucets are compatible with freestanding, clawfoot, and drop-in bathtubs.
