The connections should be the same as your faucet and should attach directly to it once the faucet is installed. One question I would have is that it specifies that it has a vacuum breaker/backflow preventer, but does not say if that applies to the hand held and the spout, or just the handheld. Typically, that type of bathfaucet is NOT legal because the water outlet is below the rim of the tub. In any case, the way the pictures were taken, it would seem that any vacuum breaker on the faucet itself would still be below the tub's rim which would make it unacceptable for any tub. The #RM376-cp would be a properly installed leg tub faucet with handheld.
