This type of control is more common for a kitchen sink faucet in the U.S. than the bathroom. Just picture a one-handle kitchen faucet with a long hose attached. At the end of the hose is the shower head. It’s much easier to convert an old tub faucet to a shower this way, than by opening up the wall to run a pipe up to a fixed shower head.
