Positioning and drilling: Clean the wall where the cabinet will be installed. Accurately mark the positions for the mounting holes according to the bathroom cabinet size. Drill holes with an electric drill and insert expansion plugs to ensure the wall can bear the weight (solid walls are best; for hollow walls, use specialized expansion fixtures). Securing the cabinet: Align the bathroom cabinet with the wall markings, use screws to fasten the cabinet through the mounting holes into the expansion plugs. After tightening, check if the cabinet is level; if it’s tilted, adjust slightly with shims. For floor-standing cabinets, make sure the cabinet sits firmly on the floor. Installing the basin and faucet: Seal the joint between the basin and the cabinet with silicone caulk. After it dries, install the faucet, connect the water supply pipes, and wrap with PTFE tape to prevent leaks. For under-mount basins, secure the clips first, then fit the basin to the countertop. Connecting the drainage: Connect the drain assembly to the basin drain outlet, wrap with PTFE tape, and tighten. Then connect the drain pipe to the drain assembly and the wall drain outlet, ensuring tight connections while leaving slight room for expansion. Water test and inspection: Turn on the faucet to test the flow of hot and cold water. Check all connections for leaks, and ensure drawers and cabinet doors open and close smoothly. Finally, clean off excess silicone caulk and installation marks. Key notes: The pre-set positions for water and electricity must match the cabinet. Turn off the main water valve before installation. Use waterproof and mold-proof silicone caulk, and wait 24 hours after drying before normal use.
