Place the stopper into the drain body and work the drain plunger. Make any adjustments by moving the lever assembly up or down in the holes provided. The main difference in this installation is that most models require the faucet handles, flanges and faucets to be removed. The assembly is then inserted from underneath the lavatory frame. The exposed deck has a chrome housing above the sink, while the concealed deck has only a flange exposed just below the faucet handles.
All faucets come with manufacturer's installation instructions.
Read these instructions carefully and follow each step for a good installation. If instructions are unavailable, you can follow the same basic instructions given for installing a lavatory faucet. The first challenge in installing bath and shower faucets is getting the faucet assemblies behind the wall. Most home builders provide a rear access panel. By removing this panel, you can connect fittings without defacing the bathroom wall.
