Tips and Ideas for Your Undermount Bathroom Sink
Now that we’ve shown you some of the best undermount bathroom sinks on the market, we wanted to give you some tips and ideas for how to make the most out of your sink.
Tip #1: Don’t Overcrowd Your Sink
One of the biggest mistakes people make with their sinks is overcrowding them with products. We get it, you want to have everything you need right at your fingertips, but sometimes less is more. Instead, opt for a minimalist approach by only keeping the essentials on hand.
Tip #2: Keep It Clean
Another important tip is to keep your sink clean. This doesn’t just mean wiping it down every once in a while. It also means using the right cleaning products that won’t damage your sink over time. We recommend using a non-abrasive cleaner and a soft cloth to keep your sink looking shiny and new.
Idea #1: Add Some Greenery
If you want to add a pop of color to your bathroom, why not add some greenery? A small vase of flowers or a potted plant on your sink can make a huge difference in the overall look and feel of your space.
Idea #2: Upgrade Your Faucet
If you really want to take your sink to the next level, consider upgrading your faucet. A sleek, modern faucet can give your sink a whole new look and feel. Plus, it can make washing your hands a more enjoyable experience.

Step 5: Lower the Sink Into Place
Next, carefully lower the sink into place. Make sure it’s correctly aligned and that the edges of the sink are flush with the countertop.
Step 6: Secure the Sink
Once your sink is in place, it’s time to secure it. This usually involves tightening mounting clips or screws underneath the sink. Be sure to follow the manufacturer’s instructions carefully.
Step 7: Reconnect the Plumbing and Turn on the Water
