Undermount Bathroom Sinks Buyer's Guide

Aside from aesthetic considerations, there are practical considerations that you should look into when buying an undermount bathroom sink. These include its shape, size, material used, and budget.

Shape

Just like traditional sinks, undermount sinks also come in different shapes so that you have enough options to choose from. These are usually undermount rectangular bathroom sink with defined edges or slightly rounded for a softer appeal.

In choosing the shape, you should primarily consider the sink’s purpose. If you want better drainage, then you would prefer a rounded sink with sides that steeply slope towards the drain.

On the other hand, if you want a sink that can hold enough water, then I would recommend one with gentler angles and more defined edges.

The imagined finished look of your bathroom should also help you in determining the shape that would best go with it.

Size

Another factor to consider is the sink’s size. Average bathroom sink sizes range from lengths of 18 to 24 inches for rectangular undermount sinks or diameters of 16 to 20 inches for rounded sinks.

Nevertheless, some manufacturers also make smaller or bigger bathroom undermount sinks depending on the customer’s needs.

As a tip, make sure to check out your bathroom’s counter size first so you get the appropriate-sized sink for it. After all, you wouldn’t want to have a sink that’s too big for your undercounter bathroom sink .

Material

Sinks can be made with various materials including ceramic, granite composite, and stainless steel. In fact, some sinks are even made of glass!

But for bathroom use, the more common materials used are ceramic and granite composite - especially when it comes to undermount bathroom sink installation.

Ceramic or porcelain is easier to mold so you can expect sinks coming in a variety of shapes and sizes. It can also be coated with different colors, and this makes ceramic sinks more versatile.

They’re durable yet very affordable, so it’s a great option if you’re on a tight budget. The only downside is that this material is heavy, so you would need a strong countertop for it to mount on.

The lightweight alternative to ceramic is granite composite material. It is similarly durable and scratch-resistant, so you know it’s not something that gets worn down easily. However, they’re harder to make, so they can come at steep prices.

Budget

You should also factor in your budget in making your purchase. The average price of decent bathroom sinks undermount ranges from 50 dollars to a little over a hundred dollars, while the more top-tier ones can go as high as 500 dollars.

This means that there are enough options for you regardless of your budget. However, don't just think about the price of the sink.

You should also consider the cost of hiring a professional to have them installed, and how tricky the installation will be. These factors can greatly affect your budget, so don't forget to keep them in mind.

Undermount Bathroom Sink

If you ask me, the undermount bathroom sink should be one that's durable, affordable and one that has a timeless appeal. This means that even if you decide to update your bathroom's interior, the sink won't be an eyesore because it still blends well with it.

Best Undermount Bathroom Vanity Sinks

As for the best Undermount bathroom vanity sinks, I think you should stick with smaller variants so that you still get enough counter space for your needs. But if you have a big bathroom space, I don’t see why you should limit yourself to small rectangular undermount bathroom sink .

Best Bathroom Sinks: Undermount Installation

With Undermount installation, the under counter bathroom sinks instead of just being mounted on top of them. This makes them a lot easier on the eyes, and that quality makes them the best bathroom sinks. Undermount installation also helps to achieve that clean and expensive aesthetic.

Best Undermount Sinks Bathroom: Material

As to the material, I think ceramic makes the best Undermount sinks for bathrooms. Bathrooms are a means to give you that laid-back feel, and you can only get that with ceramic or granite composite sinks. The affordability of ceramic, however, gives it more brownie points.

Nevertheless, granite composite is more lightweight, so if you have the extra budget and would want to have standalone sinks, you can’t go wrong with that material.
