What is the difference between undermount and top - mount double sink wash basins?

Jun 17, 2025

Hey there! As a supplier of double sink wash basins, I've been getting a lot of questions lately about the difference between undermount and top - mount double sink wash basins. So, I thought I'd write this blog to clear things up for you.

Let's start with undermount double sink wash basins. These bad boys are installed underneath the countertop. One of the biggest advantages of undermount sinks is the sleek and seamless look they provide. The countertop extends right to the edge of the sink, creating a clean and modern appearance. It's like having a smooth, unbroken surface in your bathroom, which can really elevate the overall aesthetic.

For those who are into a minimalist style, undermount sinks are a dream come true. You won't have that lip around the sink where dirt and grime can accumulate. Cleaning is a breeze! You can just wipe the countertop, and all the water and debris will slide right into the sink. No more scrubbing around that annoying edge.

But there are some downsides too. Installation can be a bit tricky. It requires a more skilled installer because the sink has to be properly supported from underneath. If it's not installed correctly, there's a risk of the sink coming loose over time. And they're usually a bit more expensive than top - mount sinks. The additional labor and materials needed for the installation add to the cost.

Now, let's talk about top - mount double sink wash basins. These are the more traditional option. The sink sits on top of the countertop, and it's secured with a bead of caulk around the edge. One of the great things about top - mount sinks is that they're easier to install. You don't need to worry as much about supporting the sink from underneath. A DIYer with some basic skills can often tackle the installation themselves.

Top - mount sinks are also more budget - friendly. Since the installation is simpler, the overall cost is lower. They're a great option if you're on a tight budget but still want a double sink in your bathroom.

However, the main drawback of top - mount sinks is the appearance. That visible edge around the sink can make the countertop look a bit cluttered. And as I mentioned earlier, it's a magnet for dirt and grime. You have to be more diligent about cleaning that edge to keep your bathroom looking fresh.

When it comes to choosing between undermount and top - mount double sink wash basins, it really depends on your personal preferences and budget. If you're all about that modern, clean look and have the budget to spare, an undermount sink might be the way to go. But if you're on a budget or prefer an easier installation process, a top - mount sink could be your best bet.
