Key Factors for Buying Undermount Bathroom Sinks

Material

Undermount bath sinks are made from an array of materials. However, for most models, you will find they are constructed from Vitreous China, porcelain, or ceramic.

Generally, sinks made of ceramic and porcelain are coated with vitreous china, an enamel layer for enhancing strength. As for ceramic, these sinks are resistant to scratches and chipping. They can also withstand everyday usage but not extreme impacts.

Just like high-quality ceramic sinks, porcelain sinks are also pottery-based. Even so, porcelain is significantly more durable than ceramic since it contains steel. The downside is that porcelain sinks come in simple and plain designs. Overall, we recommend choosing a sink made of ceramic and vitreous China or a combination of porcelain and ceramic.

Sink bowl shape design

Another deciding factor for your undermount bathroom sink is the shape of its bowl. You will have to decide whether to choose a rectangular, oval, round, or square-shaped sink bowl.

Overall, the right shape depends on your bathroom style. For instance, if you want more of a traditional look, a round or oval-shaped one would be your best choice. However, for a more modern and contemporary design, we suggest you get a rectangular bathroom sink or a square bowl.

Color

An equally important factor to consider is the color of your under-counter bathroom sink. After all, it does play a critical role in bathroom aesthetics.

As you might have noticed in my undermount bathroom sink reviews, most models are white in color. This is because white tends to create a clean and classy look for your bathroom vanity. Some are pure white, and others off-white.

However, these sinks do come in other color variations, including biscuit, bone, black, almond, bluestone rutile, bourbon rutile, and linen. So, the important thing is to choose a color that complements your countertop.

Overflow drain

An overflow drain is an important feature in any sink. It helps prevent water from overflowing and spilling over if it fails to drain fast enough. This might happen if your drain is clogged up or if you happen to leave the faucet on accidentally.

However, not every undermount sink for the bathroom you come across will be fitted with an overflow hole. But for enhanced performance, you should look for a model with at least one overflow drain.

Size and depth

Just like the shape, these units come in a range of sizes to choose from. However, the right size largely depends on how big your bath space is. Because if you have a tight bath space, you’re better off choosing a small rectangular undermount bathroom sink. Simply, choose something that is less than 20-inches long.

However, if space is not an issue, then you can go for a large-sized sink. Such a unit can handle various bathroom task options with ease and comfort.

More so, you must consider the depth of the sink. Undercounter sinks for the bathrooms have different depths ranging from 5.75-inches to 9-inches. Of course, a deep undermount bathroom sink is more convenient to use than a shallow one. Because with a deep sink, you won’t have to worry about water spilling on the counter or floors.

Warranty

Just because different undermount bathroom sink manufacturers state that their products are durable doesn’t mean it’s true. Even the highest quality sink is likely to have some defects.

So, for your peace of mind, we suggest you choose a model that is covered by a warranty. Generally, some manufacturers like Kohler only offer a limited one-year warranty. Meanwhile, others like the American Standard and Nantucket provide a limited lifetime warranty. Of course, the longer the warranty period, the more durable the sink is likely to be.

Installation hardware

Sure, you cannot install an under-counter sink yourself if you’ve no prior experience. Unfortunately, not every undermount bathroom sink out there comes with a complete installation kit.

But it would be more convenient if your sink came with all the mounting hardware and installation instruction. This will definitely make installation even more hassle-free and cheaper.

Undermount Bathroom Sink Benefits and Drawbacks

Under counter bathroom sinks offer a lot of perks which explains their popularity compared to drop-in sinks. Some of the key benefits include:

Sleek design

Unlike overmount sinks, under-mount units have their edge lips concealed below the surface of your countertop. This allows the sink to seamlessly fit into any vanity or counter design for a sleek look.

Space optimization

These units don’t take up much counter bathroom space beside the sink area. Consequently, you will find them ideal for small bath countertops.

Easy to maintain and clean

Since undermount sinks don’t have exposed lips, you can easily clean them. Besides, most are made from smooth and stain-resistant materials.

Increases your home’s resale value

Because of their aesthetic appeal, Nantucket sinks add much value to any house. But you have to choose a high-quality model.

Even with their many benefits, undermount bath sinks also have some drawbacks. These include:

  • Quite pricey considering you also have to hire an expert to install it for you.
  • If not properly installed, you could experience leaking, thereby leading to mold build-up underneath the sink.
  • Compatible with a few faucet options. You can only mount the faucet on the wall or counter.

Rectangular vs. Oval Undermount Bathroom Sink

Undercounter bathroom or kitchen sinks come in various shapes. Even so, the most common ones are rectangular and oval. Each style comes with its own set of unique pros and cons. For instance:

Look and style

Rectangular sinks boast sleek lines along with clean corners. As such, they tend to appear more stylish and elegant. Because of this, they can be a perfect choice for your modern bathroom design.

Oval Nantucket sinks, on the other hand, have a classic design. Simply, they look more traditional than their rectangular counterparts. Consequently, you can easily pair them with nearly any bathroom style. However, they are often referred to as outdated.

Fitment

Most sinks with a rectangular shape design are best suited for large bathroom spaces. This is because they do take up a lot of counter space. Meanwhile, an oval undermount sink is built to fit into tight spaces without a problem. You can actually mount it in the corner of a small bathroom.

Water splashing

Even with deep depths, rectangular undermount bathroom sinks are more prone to splashing water than their oval counterparts. Because of their oval design, they tend to feel somewhat deeper, thereby offering better water depth.

Undermount Bathroom Sink Sizes

One of the deciding factors when choosing the under-counter bathroom sink is size. That’s why there are both small and large Nantucket sinks.

However, the right size sink depends on the overall size of your bathroom and base cabinet. After all, it would not make any sense to install a large-sized unit in a smaller bathroom.

Generally, most oval or round undermount sinks typically measure between 12 and 17 inches in diameter. As for rectangular design models, they can range from 12 to 20-inches in length and 16 to 24-inches in width. So, overall, oval-shaped sinks have a more compact size style than their rectangular design counterparts.

In terms of depth, it ranges from 5 to 8 inches for both oval and rectangular undermount sinks. Of course, the deeper the sin,k the better to avoid water spills. Also, a deeper sink prevents overflow issues.

Materials for Undermount Bathroom Sink

Do you want a long-lasting undermount bathroom sink? If yes, you must choose one made of the best materials. This could be a combination of vitreous China and ceramic or porcelain and ceramic. Let’s find what each material has to offer.

Vitreous China

This is an enamel coating applied to ceramic sinks. The coating helps make your ceramic undermount bathroom sink tougher, shinier, and denser. Compared to other coatings, vitreous China is far better at resisting scratches, spills, stains, and other imperfections.

Ceramic

Ceramic is another high-quality material for under-counter bath sinks. Basically, it comprises a combination of powder, clay, and water. Therefore, you will find it resistant to scratches, chipping, stains, and bacteria build-up. Even better, it offers exceptional durability when combined with vitreous China.

Porcelain

This material is a solid form of ceramic but lacks a glazed coating on it. Even so, it is pretty tougher than ceramic. The best part is that porcelain is non-porous, making it easy to clean.

However, this material is more prone to staining and chipping. For this reason, most undermount bath sinks usually feature a combination of porcelain and ceramic materials.

Which Finish is Best for the Undermount Bathroom Sink?

For enhanced durability and protection, undermount bathroom sinks come in various finishes or coatings. However, not every finish is as durable as it is reported to be. So, below are some of the best finishes to consider.

Porcelain enamel

This is a type of glass coating commonly found on ceramic undermount sinks. The finish makes your sink harder, extremely corrosion, and heat resistant.

High-gloss ceramic

This is one of the most versatile sinks finishes for undermount models. And compared to the porcelain enamel finish, it tends to give your sink a modern and sleek feel. The best part is that it’s easy to clean.

High gloss or crystalline glazed finish

Undermount bath sinks with this kind of finish have a smooth and clean surface. But one of the best things about this finish is that it inhibits the growth of bacteria. Consequently, this makes your sink more hygienic.

Final Thoughts

The above products stand out for their exceptional durability, reliable performance, and even design. So, whichever sink you choose from the list, you won’t be disappointed.

The important thing is getting a model that complements your bathroom style, whether modern or classical. You must also consider the sink’s size, shape, warranty period, and availability of an overflow drain.

But which is the best undermount bathroom sink from the reviews? In our opinion, it will have to be the KOHLER K-20000-0 Caxton Under-Mount Bathroom Sink. This is because thanks to its timeless design, you can use it in any bathroom style.

The best part? It has a great depth and overflow drain to prevent water from splashing out on your counters. On top of that, it comes with the necessary mounting hardware at a reasonable price.
