A small undermount bathroom sink is a great household product that will give you a long period of leak-free use, provided of course you install it in the correct manner. In the next few minutes, you will discover a simple, step-by-step method you can use to mount this accessory in an area of your choice – quickly and easily. If you are currently in the process of remodeling your washroom and plan on using the existing countertop, make sure you measure your sink opening before going ahead and investing in the above-mentioned model.

Also, keep in mind that brand new countertops will require a hole cut out, utilizing the template that comes with it. Tip:- In order to avoid expensive mishaps from occurring, it’s best that you hire the services of an expert to complete this part of the job for you. Okay, with that said, let’s get down to the actual process of installing a small undermount bathroom sink! First off, here are the things you are going to need: a jigsaw, silicone caulk, sawhorses, a pencil, caulking gun, colored electrical tape, denatured alcohol, a drill, 1-inch hole saw and fine-grit sandpaper.

Once you have assembled all of these items, it is time to get started. Step one – Carefully position the countertop face up on a set of sawhorses. Place the cutout template that comes with your new sink and use a pencil to trace it onto the countertop. Simply put, what you are doing here is tracing the location of the sink and the three holes for the faucet onto the surface of the former. Step two – Thereafter, you want to drill holes inside the traced corners of the countertop with your drill and one-inch hole saw. Next, carve the traced template out of it using a jigsaw.

Drill the holes for the faucet with a hole saw. Then, grab hold of some fine-grit sandpaper and sand the edges until they are smooth. Moving on to step three – Now turn the countertop the opposite side – this time, with the bottom facing up. Lay the small bathroom sink on it and make sure it stays in the center. After you have done this, trace the corners of it with your pencil. Lift the sink up and firmly place it with the bowl facing up. Step four – Use the denatured alcohol to clean the rim of the sink and mounting edge of the countertop. Doing this will prepare the surfaces for the application of silicone caulk.

Here’s step five – With a caulking gun, apply a 1/4 inch bead of caulk around the top rim of the small undermount bathroom sink. Afterward, it is important that you cover the perimeter of the rim as this is what will ultimately seal the sink to the countertop. Next, set it over the top, taking care to position it between the corner tracings. Press on the sink to ensure it stays in place. Step six – Now, fasten the mounting clips around the sink. Thereafter, you will need to drill pilot holes in the countertop for the mounting screws. Use a drill bit that is smaller than the screws and place it against the outside edge of the top. Fix the tip of the bit approximately halfway between the thickness of the countertop. In order to mark the halfway point, you may stick a piece of colored tape around the bit.

This’ll prevent you from accidentally going all the way through the countertop, when drilling the pilot holes. Let’s check out step seven – Drill pilot holes for each and every clip around your small undermount bathroom sink, using the tape as a rough guide. Once you’ve finished this task, you want to position one end of the clip over the sink and the opposite end above the countertop. Then, mount the clip with the main securing screw and a screwdriver, preferably one with a Phillips head.

Finally, complete the installation of the countertop according to the manufacturer’s instructions. Wait for at least 24 hours before attaching the faucet and plumbing to your small bathroom sink and countertop. This time period is sufficient to allow the silicone to properly set. Well, that’s a wrap for this article. Hopefully, you will now be able to mount a small undermount bathroom sink all on your own, without having to shell out big bucks by engaging the services of a professional.
