What Makes a Good Undermount Bathroom Sink?

under mount sink

There are plenty of options out there, but which qualities turn an undermount sink into the finest one? Let’s take a look at what makes an undermount sink top of its class.

High-Quality Material

Your bathroom sink should be made of highly durable material that doesn’t get damaged or stained in a breath. If you want to go for a high-end one, you can choose a copper sink, but they are pretty high maintenance.

However, for better maintenance and affordability, you should stick to porcelain or ceramic sinks.

Perfect Color

You should choose the color of your undermount sink according to the bathroom décor and the countertop pattern. You can go for plain colors as it is the safest choice.

But if you want to go out of the box, you can pick different colors and textures. In this case, you need to get the one that compliments your countertop. Otherwise, things will look messy!

Excellent Draining

When it’s about an undermount sink, the draining has to be a top-notch one. You can go for the pop-drains if you want to fill up the sink bowl. And always try to get the one with an overflow for a better and faster water pass.

The Accurate Shape

You can either go for a classic rectangular shaped sink or an oval one, whichever you prefer. But if the sink has sharp angles, it will be harder to clean, and you should remember that.

If you want to modernize your bathroom, you can go for the whimsical ones. But the classic ones never go out of style; you know that, right?
