Are you overwhelmed by too many countertop choices?

Maybe you're going about it the wrong way!

It's the pallet that counts!

kitchens and baths
At our showroom you can have at your fingertips Granite countertops, Quartz countertops such as Cambria, Caesarstone & Silestone as well as fine wood countertops - we have them all on display in our showroom in large format twenty pound slabs.


It's what you and your designer do with all of these selections that make the difference.

One of the first steps in our kitchen design or bath design process is the creation of a pallet. Together we help you build this pallet. We select the right cabinet line, species, and finish, coupled with the countertop, the back splash and the floor. Then we add the fixture finish perhaps a second cabinet species & finish and even a second countertop for the island. We know its right when you say WOW! That's it. I love it.

At Nordstrom’s, how useful do you find the mannequins? Some of us can't pick out our new clothes without them!

- Sam & Donna M. Testimonial

"To the entire crew at Signature Kitchens, Additions and Baths - We are so Happy with our Home Addition. The kitchen design and our new kitchen cabinetry have simply been transformative.' Each and every one of you has been a real joy to work with throughout the entire process and the workmanship and professionalism is outstanding. It's nice to know there are still companies like yours in business who put the customer and quality first."

No matter how beautiful you want your kitchen to be its core function is cooking, preparing, cleaning, and entertaining. In other words your kitchen is a space in which you work. The space you work on is the countertop. There is more to your countertop selection than simply complimenting your cabinets, although in the kitchen design we can get pretty obsessed with that.

Quartz Countertops - Silestone, Caesarstone, and Cambria Countertops

Quartz countertops or "man-made natural stone", is manufactured by suspending a mineral compound i.e. quartz in a polyester or acrylic resin. The manufacturing process creates a beautiful, durable, non porous, low maintenance, surface which is highly resistant to bacteria, water, heat and staining. Although the degree of these attributes varies from manufacturer to manufacturer. Like granite countertops, quartz countertops take the same edge profiles, allow for an integrated sink and or backsplash and come in slabs in hundreds of unique and exciting colors. Keep in mind, anything that comes mined or manufactured in slabs is going to have a seam somewhere, although with quartz countertops it can be harder to find the seam. Read on to learn more about our Silestone, Ceasarstone and Cambria quartz countertops.


Silestone is manufactured by a company called Cosentino, which began operations 70 years ago in Almeria, Spain. The Cosentino family was in the stone industry that is they were making countertops and other residential and commercial products out of granite and marble. Today 70 years later, Silestone controls more than 50% of the U.S. quartz countertop market. Sort of like the Google of quartz countertops.

Silestone offers the unique combination of built-in Microban® antimicrobial product protection, National Sanitation Foundation certification and GREENGUARD Indoor Air Quality Certification. Microban protection inhibits the growth of microbes such as odor-causing bacteria, mold and mildew. While Microban protection does not protect users from foodborne illness and is not a substitute for normal cleaning practices, it does result in countertops that are easier to clean and stay clean.

Certifications by the National Sanitation Foundation and the GREENGUARD Environmental Institute mean Silestone Quartz countertops are a Safer Surface for areas where food preparation takes place, while protecting the quality of your indoor air quality because it has low-to-no emission (off gassing) of toxic chemicals into the indoor environment. Silestone is GREENGUARD certified for low emitting interior building materials, furnishings, and finish systems used in educational (daycare and K-12) environments. All GREENGUARD Children & SchoolsSM products have been tested for their chemical emissions performance.
