A professional plumber roughed in the connections for the wall-mounted faucets. This is especially important if replacing a traditional, sink-mounted faucet with a wall model, since the supply lines must be relocated.
Attach the spout to the wall plate. Make sure to position any washers and other hardware according to the manufacturer's instructions, then tighten the bolts down with an Allen wrench. (Different faucets may require different tools to tighten.)
Position the plate and spout on the wall and tighten the bolt to secure it.
Add the handles and any necessary hardware, including hot and cold taps. Finger-tighten the handles.
