The bathroom is another area of the home that can be greatly improved using stones. You need a quality counter in there just as you would in the kitchen. This is where some people use hot curlers, flat irons and other styling appliances that use high heat. Besides this, you need a counter that can withstand cosmetics that most people like to sit on counters. If one spills, you don’t want to have to worry about etching and other damage. Durable stones that can withstand this include quartz, granite and marble. So, consider these when upgrading the counters in your bathroom.

Granite Countertops in Rockville, MD

Who doesn’t like a granite countertop? These look amazing in both bathrooms and kitchens alike. They come in an array of colors to choose from, making them a great choice for any décor. What’s great about granite stone is that it has a natural rocky look with beautiful veins. No two slabs look alike, which makes each countertop unique. The veins are like fingerprints, coming in different colors and tones. The durability of granite is also worth noting. Granite isn’t susceptible to scratches, chips and stains. It is nonporous, so it doesn’t harbor bacteria, which is a big plus for sanitation purposes.

Marble Countertops in Rockville, MD

Marble’s ability to stay cool makes it attractive to chefs and homemakers. Those who like to bake in the kitchen know how convenient it is to be able to set pots and pans on the countertop. With marble, you can do that since it’s resistant to heat. You can also use it for rolling out dough and making pastries. It’s the ideal countertop for the kitchen. But it’s also worthy of being placed in the bathroom. Since it can withstand heat, it’s great for restrooms where heat styling tools are used. The appearance of marble is what attracts most people to it initially. It comes in many different colors and hues.

Quartz Countertops in Rockville, MD

Quartz counters are made by people using a mix of quartz, pigments and resin. The resin acts like a sealant, helping to protect the quartz from harsh conditions. And what’s great about the pigments is that you can sometimes have a supplier dye the stone to whatever color you desire. The durability of quartz makes it an attractive option for kitchens and bathrooms. It is water resistant, stain resistant and heat resistant. And you don’t have to worry about regularly sealing it, like you do with marble and granite. The maintenance of quartz is minimal, making it a breeze to own.

Customer Says

When my wife and I moved into our new home in Rockville, I was pleased with the look of the counters. It was made with laminate that resembled marble, but didn’t have the same great qualities. So, within a year of owning the home, the surface was scarred and damaged in various ways.

So, we decided to redecorate the kitchen with quartz and chose this because it offered the natural look of stone, while offering superior durability. We came across KNC on Facebook, where they had a post showcasing some of their work. We visited their showroom and chose the quartz stone we wanted. Someone came to our home and gave us an estimate.

My wife and I agreed to the price right away. KNC gave us a 3D digital model, so we could see what the result would look like. The actual results were even better. We highly recommend this company to anyone in Rockville looking for countertop upgrades.
