How to Mount a Bathroom sink
If you’re considering installing a new bathroom sink, Curtis Plumbing has got you covered. Our team of professional plumbers can provide you with expert installation services to ensure that your sink is mounted securely and functioning properly.
Before you begin the installation process, it’s important to gather all of the necessary tools and materials. You’ll need the appropriate sink and sink plumbing components for your specific sink style, a bucket, adjustable wrench, pliers, utility knife, chisel, power drill, hacksaw or another pipe cutter, pipe thread sealant, or plumber’s tape, plumber’s putty, and a friend to help lift the sink.
It’s important to note that if you have a granite or marble countertop, you should avoid using oil-based plumber’s putty, as it can cause bleaching on your countertop. Instead, opt for a non-staining alternative such as silicone sealant.
When mounting the sink, it’s important to ensure that it is level and securely attached to the countertop. This will prevent leaks and potential damage to your bathroom. Our team of professional plumbers has the expertise to properly mount your sink and ensure that all plumbing components are functioning properly.
How to Remove an Old Sink
If you’re replacing an old bathroom sink, it’s important to properly remove it to avoid any damage or potential issues during installation. Follow these simple steps to learn how to remove an old sink.
- Begin by disconnecting the water supply to your sink. Locate the two shut-off valves below or behind the sink and turn them both off. It’s important to test both faucets handles to ensure that the water is shut off. Place a bucket beneath your sink to catch any residual water.
- Using an adjustable wrench, loosen the nuts holding the hot and cold water supply lines to the shut-off valves until they can be removed. Be prepared for some residual water to drip out of the lines, which is why the bucket is needed.
- Disconnect the drain connection. Use pliers to loosen the large slip nut holding the P trap to the tailpipe of your sink’s drain until it’s loose enough to remove easily. You may also need to loosen the large nut holding the trap assembly to the waste pipe in your wall if you need to remove the entire trap assembly.
- If your sink is installed on a vanity, use a power drill to unscrew the clips holding the sink to the underside of the countertop. If your sink is wall-mounted, pedestal, console, or corner style, remove the bolts holding the basin to the wall. You might need a friend to hold the sink for you while you do this so that it doesn’t fall.
- Run a utility knife along the crease between your sink and the countertop or wall to release any silicone sealant or caulking.
- Finally, lift up the basin to remove it from the countertop or wall. If your sink has a pedestal or console attachment, remove that after you take off the basin.
How to Install Bathroom Sink Hardware
To install faucet hardware for a countertop sink, place a gasket (if available) or plumber’s putty around the spout’s underside. Then, secure the spout in the installation hole by tightening a nut or plate beneath the sink or countertop.
To install the faucet spout, put a gasket under it or use a plumber’s putty. Place the spout in the hole and secure it using a nut or plate under the sink or countertop. Avoid over-tightening and remove extra putty.
If the faucet handles are separate from the spout, install them using the same process as the spout. Position each handle. Then, secure it with a nut or plate beneath the sink or countertop using a wrench or drill.
How to Connect Faucet Supply and Water Supply Lines
With the spout and handles in place, it’s time to connect the faucet supply hoses. Wrap the plumber’s tape around or apply pipe thread sealant to the threads (grooves) of the supply line hose mounts under each faucet handle. Then, attach a flexible supply line hose to each of those mounts and tighten using a wrench on each corresponding nut. Using the same method, attach the other end of each supply line hose to the corresponding side of the T-shaped supply line and mount on the underside of the spout. Make sure to tighten everything securely but not too tight, which could damage the hoses or mounts.
Finally, connect the hot and cold water supply lines. Attach a water supply hose to each water supply mount under each faucet handle using the plumber’s tape or pipe thread sealant, a wrench, and the applicable nut. The water supply hoses will be thicker than the faucet supply line hoses and will eventually be connected to the water supply valves in your wall. Double-check that everything is tight and secure before turning on the water supply valves and testing the faucet for leaks.
How to Mount a Bathroom sink
- Drill holes in the underside of your countertop for clip screws if your countertop doesn’t already have them.
For under-mount and drop-in sinks, you will need to drill holes in the countertop where the clips or screws will go. Make sure to use the right size drill bit for the clip screws you will be using. Position the clips at the corners of a rectangular mount or equidistant around a round mount.
- Apply sealant to the sink.
Squeeze a thin line of silicone caulk to the edge or edges of the sink that will be adhered to the wall or countertop. This will help to create a waterproof seal between the sink and the countertop or wall.
- Mount the sink on the countertop or wall.
If you’re installing a drop-in, vessel, or trough sink, lower the sink and its hardware into position onto the countertop. However, for an under-mount sink, you’ll have to mount the sink from below. For wall mounts, ensure that the sink is level before proceeding to the next step.
- Secure the sink in place using clips or bolts.
Clip and tighten sink clips into countertop holes for countertop-mounted sinks. Mount wall-mounted sinks by drilling a basin into the wall with lag screws. Enlist a friend to hold the sink in place during installation. Clean up excess silicone for a neat finish.
Installing the sink with the countertop upside-down can make it easier to access the underside. It can also help prevent damage to the sink or countertop during installation. This will allow for better visibility during the installation process and is particularly helpful for installing an under-mount sink.
How to Connect a Bathroom Sink to Your Plumbing
Are you planning a bathroom renovation or simply need to replace your sink? Connecting a bathroom sink to plumbing is doable with the right tools and steps.
- Connect the hot/cold water supply lines to valves on the wall with the plumber’s tape. Use compression nuts/brass ferrules.
- Install the lift rod by lowering it to the top of the faucet and attaching the clevis strap to the bottom using the clevis screw. This will allow you to operate the sink stopper.
- Install the pop-up flange by caulking or using putty under it. Push it into the drain opening and secure it with a washer and lock nut, but don’t over-tighten.
- Install the tailpiece mount by placing a gasket into the top of the T-shaped piece with the side opening. Screw it in place using a wrench, making sure that the side opening of the tailpiece is perpendicular to the dangling clevis strap. Adjust if necessary.
- If you removed the P trap assembly, reconnect it to the waste pipe in your wall and tighten using a wrench on the applicable nuts and washers.
- Install the tailpiece by fitting it snugly between the tailpiece mount and the P trap. If it’s too long, use a pipe cutter to shorten it. You may need to loosen the P trap and move it aside to fit the tailpiece under the tailpiece mount. Apply tape or sealant to the tailpiece grooves, then screw it in place. Secure it with the accompanying nut and gasket.
- Lower the pop-up stopper to the bottom of the sink.
- Finally, install the pivot rod by fitting it ball-first through the side opening in the tailpiece mount. Attach the spring clip onto the pivot rod, along with the clevis strap. Secure the pivot rod into place with the pivot nut and accompanying gasket.
