A Buyer’s Guide to The Best Undermount Bathroom Sinks For Quartz Countertops

Purchasing the best undermount bathroom sink can be overwhelming since the market is saturated with several undermount units with varying brands. For this reason, you need several pointers to help you maneuver the various under-mount sinks for a reliable unit. Below are factors to consider when looking for the best undermount bathrooms sinks for quartz countertops.

1. The Weight

How heavy is the unit you intend to purchase? It is worth noting that the heavier the under-mount bathroom sink is, the more durable and long-lasting it is likely to be. Undermount bathroom sink materials such as fireclay, granite, and marble, to mention a few, make some of the heaviest units.

That said, the heavier the sink, the more support it will need from the cabinets underneath it. So, ensure that your cabinet is strong enough to reinforce the purchased under-mount sink.

2. The Bowl Shape

When choosing the bowl shape for the best under-mount bathroom sinks for quartz countertops, you should consider the intended purpose and the envisioned look you want for your bathroom. Undermount units come in different shapes, including oval, round, square, and rectangular undermount sinks.

For better drainage, you should consider a round sink whose sides steeply slope towards the drain. An under-mount sink with defined edges and gentle angles is perfect when looking for a unit that holds enough water. A square or a rectangular undermount sink is ideal when going for a modern or contemporary appearance.

That said, ensure that you consider the ease of cleaning when choosing an ideal bowl shape. Undermount sinks with more edges and levels may require more time to clean and maintain.

3. The Drain

The under-mount sink drain plays an essential role in keeping the sink and the bathroom clean-it is the channel through which wastewater travels to the septic tank. When choosing an ideal drain, you should consider its functionality.

Now, bathroom sink drains are either pop-up or grid. A pop-up drain can open and close to allow water to build up in the sink through a lever behind the faucet. Grid drains do not close, so water is always draining.

You should also ensure that the drain size on your under-mount bathroom sinks is large enough to accommodate all your needs. You should further ascertain that the stopper for your pop-up drain fits correctly to prevent water from seeping out.

4. Sound Absorption

The sound of water as it hits the sink while using the unit can be annoying. The best undermount bathroom sinks for quartz countertops, especially those made of stainless steel material, have noise-reducing pads or are covered by a sound-deadening material to absorb sound and vibrations. Be sure to check noise-proof features when buying an undermount sink for your bathing area.

5. Heat Safety

You want to ensure that your undermount bathroom sink is durable enough. So you should check to ascertain that it can stand drastic heat changes from cold to hot without cracking due to sudden expansion or contraction.

6. The Material

The material used to make the best undermount bathroom sinks for quartz countertops contributes to its appearance and durability. The following are the various materials used to manufacture undermount bathroom sinks.

Let’s dive in.

a) Porcelain

A porcelain undermount bathroom sink is one of the most durable units in the market. This is because it is derived from the hardest clay. Porcelain is one of the most common bathroom sink materials, thanks to its long-lasting and attractive appearance.

Most cast iron sinks are enameled with porcelain to improve their appearance and quality. That said, porcelain under-mount sinks can be expensive and may not be ideal if you work under a tight budget.

Porcelain also rusts when exposed to rusted metal, including the bottom of shaving cream cans, so you have to spend more time removing the rust stains to maintain their appearance and avoid staining your quartz countertops.

b) Stainless Steel

This is the most common material for under-mount sinks as it is durable, resistant to chips, stains, and rust, complements most faucets and is easy to clean and maintain. Now stainless steel undermount bathroom sinks differ in thickness.

Gauge is the measure of a unit’s stainless steel thickness. The thicker the stainless steel, the more durable it is likely to be. An under-mount bathroom sink with a 16 gauge stainless steel is thicker than one with 18 gauge since the lower the gauge, the thicker the material.

A stainless steel undermount bathroom sink can produce a lot of noise when water is running, so you should always ascertain that it has a dampening pad on its lower side to minimize sound and vibrations. When exposed to hard water, the stainless steel undermount sinks will stain, so you should always consider the water hardness level in your home when purchasing units made from this material.

c) Ceramic

Ceramic under-mount units are one of the best bathroom sinks for quartz countertops, thanks to their ease in maintenance. This undermount bathroom sink material has a sealed surface impenetrable by dust and resistible from scratch and chippings.

d)Vitreous China

An undermount bathroom sink made of vitreous china has an enamel coating applied to porcelain or ceramic after being fired. This coating helps to make undermount sinks made of vitreous china shinier, denser, and more durable than those made from pure ceramic or porcelain.

e) Copper

Copper is one of the most coveted undermount bathroom sink materials, thanks to its vibrant aesthetic and durability. As an undermount bathroom sink made of copper ages, the material deepens in color, improving its visual appeal. That said, copper is one of the most pricy of any bathroom materials so it may not be ideal if you are working with a tight budget.

f) Stone

An undermount bathroom sink made from natural stone such as quartz and granite creates an incredible impression on your bathing area. This material is further durable, easy to install, and has an excellent heat resistant ability so it is perfect for personal usage.

That said, the best undermount bathroom sinks for quartz countertops made from the stone material are expensive to purchase and require regular maintenance and sealing since the surfaces are easily affected by mineral deposits, including soap, salt, lime, and iron. These bathroom sinks may not further be your best option if your bathing area experiences a high traffic volume.

g) Plastic

If you are looking for the best undermount bathroom sinks for quartz countertops that are easy to clean, durable, lightweight, affordable, and can serve an area with a high volume of traffic, such as an elementary school, you should consider units made of plastic.

The downside of a plastic undermount bathroom sink is that it does not bring style to your bathing area, so it may not be the best choice if you want to add charm and elegance to your home.

h) Glass

Some of the most unique and trendy undermount bathroom sinks are made of glass material. A glass undermount sink is shock-resistant, so it can stand the thermal shock, whereby temperatures drastically change from hot to cold in your bathroom.

However, a glass undermount sink has limited durability since the material is prone to breakages; therefore, it is not ideal for an area with a high traffic volume. Glass undermount bathroom sinks are further expensive to purchase and install.

7. Color

You want your undermount bathroom sink to complement the visual appeal of your quartz countertops, right? For this reason, you should be keen on your undermount sink color choice. Traditionally, undermount bathroom sinks were pure white to blend with the whitish bathing area aesthetics.

However, there are plenty of color variations to choose from today. For instance, you could go for a grey undermount bathroom sink to provide a strong focal point or a black one to blend with a modern aesthetic.

8. Size

How big do you want your undermount bathroom sink to be?

The ideal size of the undermount sink should accommodate the intended functions. When choosing the size of your undermount sink, ensure that you first consider the size of your bathroom quartz countertops. You do not want the undermount sink to be too big for your counters, or do you?

A rectangular bathroom sink has an average size ranging from 18 to 24 inches long and 16 to 20 inches in diameter for rounded sinks. Different undermount bathroom sink brands manufacture smaller or bigger units depending on the distinct customer needs.

9. Warranty

One of the easiest ways to determine whether the undermount sink is durable enough is through checking its warranty. The longer a warranty period, the more durable a product is likely to be. Go for products with a lifetime warranty for the best undermount sinks for quartz countertops.

What’s more? A warranty is an assurance that you could get a replacement in case of defects on your purchased undermount sink.

A limited lifetime warranty indicates that the manufacturer cannot compensate you for regular wear and tear that arise when using your undermount sink.

10. Budget

How much are you willing to spend on your high-quality ceramic undermount installation? When looking for the best undermount sinks for quartz countertops, ensure that you consider the purchase cost and price of installing the sink. You may have to hire professionals to have your under-mount sink installed.

You should also consider a sink that is within your target price range. That said, do not go for the cheapest unit in the market, as this means that you may have to compromise on quality.

Ensure that you also consider the best undermount bathroom sink maintenance cost. An easy-to-clean and maintain sink with the most affordable cleaning supplies should be top of your list.

Step 1: Gather the Necessary Equipment

  • Drill
  • Epoxy Paste

Step 3: Clean the Countertop

You should clean the counter surface using alcohol and a scraper to eliminate debris, caulk, sawdust, or any dried-out adhesive around the cut-out opening.

Step 4: Insert The Sink into The Cut-out Hole

You should lift and position the sink into the cut-out hole. Since most undermount sinks are heavy, you could use stack boards to support the unit’s weight. Ensure that you center and adjust the sink in the hole to ascertain exactly where you desire it to be. You could use adjustable bar clamps to hold the unit in place as you install it.

Step 5: Glue The Studs

To install studs underneath the counter, you should hold them under the countertop and spread the epoxy paste over them. Ensure that you position the studs around the sink’s rim and its corners.

Step 6: Apply Silicone Caulk Above The Rim of The Sink

Using a caulk gun, spread a thick bead of caulk around the cut out on the quartz countertop to secure the rim of the sink.

Step 7: Tighten The Clamps

To raise the sink so that it presses against the caulk, you should tighten the clamps and check the unit’s positioning. If the sink is not positioned as you need it to be, you should adjust it before the caulk solidifies and give it time to cure.

Step 8: Install Sink Clips and Wingnuts

Sink clips help to secure the unit tightly to the quartz countertop. So you should fit clips over studs then tighten them in place using wingnuts. Ensure that the slotted end of each clip is over the stud and that the solid end is underneath the unit’s rim when positioning.

Watch out for gaps between the sink and the quartz countertops. Gaps indicate that the clips are not tight enough. Ensure that you tighten the wingnuts by hand and not overtighten them, as this could damage your quartz counters.

Step 9: Mount the Faucet

Install the faucet and other accessories over the caulk and then attach the waterlines. Next, leave the caulk to dry for at least 24 hours before using your undermount bathroom sink.

Step 5: Repeat the process up to three times if the sink does not unclog in the first attempt.

Step 6: Screw the drain cover and replace the sink stopper.

4. Use a Plunger

Step 7: Repeat steps 2-6 incase the rectangular bathroom sink is not unclogged.

Step 8: Replace the sink stopper.

5. Clean The P-Trap

Pooling of water or slow draining often indicates a clogged p trap, which simple cleaning of the unit could fix. The P trap is the elbow-shaped pipe at the bottom of the sink that prevents sewer gases and debris from rising the drain.

  • Put a bucket under the p trap
  • Use a pipe wrench, your hands, or channel locks to loosen slip nuts

  • Replace the p trap and test the drain.

  • Place a rag or towel at the bottom of the sink
  • Remove the sink stopper and the p trap
  • Insert the plumber’s snake or the cable auger into the sink drain manually

  • Push the cable into the drain as much as possible while cranking the auger’s handle to work out the entire clog
  • Remove the cable auger or the plumber’s snake from the drain
  • Check to ascertain that water starts to flow smoothly, and repeat the process if necessary.
  • Reassemble the sink’s components
  • Flush the sink with hot water.
