Most wall-mount bathroom sinks require anchoring into studs to handle the weight. Use a stud finder to locate them and mark their positions.
Pro Tip: Never mount a sink directly into drywall—you must anchor to studs or install a wall backing plate.
Determine the height of your sink. Standard height is around 30–36 inches from the floor, but adjustable depending on user needs.
Use a level to mark the horizontal line where the sink will sit, and mark holes for the mounting bracket.
Drill pilot holes into the studs. Use lag bolts or heavy-duty anchors to secure the bracket.
Important: Check that the bracket is completely level before tightening.
With help (wall-mount bathroom sinks can be heavy!), lift the sink onto the bracket and secure it with screws or mounting bolts.
Attach the faucet and drain assembly before mounting if not pre-installed.
Connect the water supply lines and P-trap.
Use plumber's tape on threaded connections to prevent leaks.
Apply silicone sealant around the edges where the sink meets the wall to prevent water from seeping behind.
Let it dry for 24 hours before use.
Mounting a bathroom sink improperly can lead to:
Wall damage or collapse
Water leaks
Mold growth
Injury
Most wall-mounted bathroom sinks can support 50–100 lbs when installed properly. If your sink is cast iron or stone, reinforcement is a must.
Installing on drywall alone is unsafe. Use wood studs, a backing board, or concrete/masonry walls.
If installing for accessibility, ensure:
Sink height is under 34 inches
Knee clearance is at least 27 inches high, 30 inches wide
