One of the biggest reasons for a wall-mount sink installation is its ability to save space. It’s also easy to clean and fashionable. Additionally, because it provides sufficient legroom for people with disabilities, it is the best option for an accessible bathroom.
Installing a wall-mount sink can be easier than installing one inside a cabinet. However, if you are converting from a traditional sink to a Wall-mount sink you will need to do some rough-in plumbing. This will require a permit. This shouldn’t be a reason to stop you from trying to do the job yourself, but you should consult a licensed plumber in order to ensure that your work passes inspection.
What is a wall-mount bathroom sink?
Wall-mount sinks can save space when compared to pedestal sinks. They also look great and are compact.
Wall-mounted bathroom sinks offer many benefits
A wall-mounted sink has the advantage of being able to be mounted at any height. This is especially useful for small basins that need to be installed in child’s bathrooms. A pedestal is not necessary for cleaning, and the plumbing can be hidden.
Bathroom sinks can be made from any of the usual materials, including ceramic and steel. However, they must be mounted on the wall. Ceramic wall-mounted basins should be carefully considered as the strength and fixings will affect the size and weight you can carry.
A Guide to Wall-Mount Sink Installation
Wall-mount sinks are attached to a bracket that is included with the item. The bracket must be attached to the wall framing and not to the wallboard. The bracket may overlap at least two wall studs if the sink is sufficiently wide. If so, you might be able to anchor it with lag screws to the studs. You will need to remove the wall covering, and attach horizontal lengths of 2×6 lumber or 2×8 lumber at the studs. If the drain and water supply lines are not already installed from a sink, it is possible to remove the wall covering.
After you have completed the plumbing and blocked work, and covered the floor, it’s easy to install the sink and hook it up. It’s actually easier than you might think since you don’t need to climb into a cabinet to make the connections.

How to install a wall-mount sink
To prevent flooding or leakage, turn off the water supply before you start the installation of the wall-mount sink.
Extend the Wall Studs
Create a rectangular hole in your wall about 6 inches above the location of the sink. Horizontally, connect to the studs on either side of it. To cut the drywall, use a drywall saw.
If you intend to reuse the tiles on a wall tiled with mortar, gently pry them off one at a time using a prybar. Use an angle grinder to cut through the cement backer board. Once it is removed, use a drill bit and a screwdriver bit to remove any screws. After you remove the adhesive, this can be reused.
Install the Blocking
Install horizontal 2×6 and 2×8 blocking between exposed studs. Make sure it is flush with the room’s edges. Then, face the room. Use a torpedo to level the blocking and position it so that the center of its face faces is in the area where the sink will be.
Complete the Rough-In Plumbing
If they are not already installed, install water supply lines and drains. Rerouting water pipes from another sink? Cut them down to 6 inches. Use a hacksaw to cut the pipe to the desired length. For copper pipes, use solder and for CPVC pipes, you can use plastic pipe cement.
It is best to hire a plumber if you need to modify or install a drain pipe. You can’t install the vent for the drain more than 5ft from the P-trap of the sink. This requires additional plumbing work you won’t want.
Finish the wall and install the shutoff valve
Completely finish the wall and floor with new drywall. Once you are done, trim the pipe stub outs so that they extend to about 2 inches beyond the wall. You can use a pipe cutter or a hacksaw to cut plastic pipes. Each pipe should have a shutoff valve installed. You can do this process by soldering, gluing, or tightening a compression fit. To hide the gap between the pipe’s wall and the valve, place an escutcheon on each of the pipes before installing the valve.
Install an adapter for the P-Trap
Most drain pipes are 2 inches in diameter. Bathroom sink P-traps are usually 1 1/2 inches. To install a trap adapter for your P-trap pipe, you will need a 2×1 1/2 reducing bushing and a compression fitting. Hand-tighten the fitting, just like the fittings on the rest. Cut the drainpipe to 1 to 2 inches above the wall. Then glue the fitting with plastic pipe cement.
Install the Sink Mounting Bracket
Mount the mounting bracket, which is part of the sink hardware set that came with the sink, on the wall. Level it using a torpedo and mark the locations of the mounting holes for lag screws. If drilling through stone or tile, remove the bracket and drill pilot holes using a drill bit and a masonry bit. To tighten the screws, place the bracket back into its original position.
Get the sink ready
Install the sink drain assembly by filling the underside with the plumber’s putty and slipping it through the hole in the sink drain. Then, tighten the nut using tongue-and-groove pliers. Follow the manufacturer’s instructions to install the faucet on the sink deck.
Hang the Sink
Follow the instructions provided by the manufacturer for how to hang the sink. Mounting hardware will include additional lag screws and washers to attach the sink to the bracket. Before tightening the screws, make sure that the sink is level from the front and back.
Install the Pop-Up Stopper
Attach a tailpiece to the sink drain. This is usually a length of metal pipe. If the faucet comes with a stopper, you will find the stopper lever hole on the tailpiece. This hole should be facing the back wall.
Insert the stopper, attach the stopper lever to the bottom of the stopper flange, and screw it to the tailpiece. Connect the lift rod to the faucet hole by inserting the rod through the hole.
Connect the drain
Cut the tailpiece to the same height as the drain opening in your wall. Slide a washer and slip the nut onto the tailpiece to install the P-trap. Then insert the tailpiece into place in the trap’s mouth and screw on the nut. Turn the trap’s other end to face the drain opening. Cut the horizontal connecting pipe included with the trap assembly to the correct length. Then, insert the trap adapter into the trap outlet.
Tighten the nuts by hand. However, if the connections are leaking, you need a pair of pliers to increase torque. This is often the case with chrome P-traps.
Connect the Faucet to your Water Supply
Attach one end of a flexible water supply line to each faucet inlet and one end to the shutoff valve. These connections can be made watertight without plumbing tape, but you will need a wrench to do so. After you have finished tightening the connections, turn on them and inspect for leaks. Tighten more if necessary.
Hopefully, you learned about the wall mount sink installation. It is simple to take down a wall-mounted sink and install a new one. Additionally, it’s a simple DIY project that will increase the functionality and space of your kitchen or bathroom.
