How To Measure For Countertops

Hey, this is Todd Bauer with Builder Surplus. I’m going to take a quick moment to help you learn how to calculate square footage requirements for Granite and Quartz countertops.

I have a small kitchen layout here that I have drawn in and it kind of represents a typical L-shaped kitchen with an island.

I am going to walk you through quickly how to calculate out the number of square feet you’re going to need.

I’ve already done a little bit of pre-work here.  In this particular layout, we have an L-shaped kitchen with a sink on this wall. Here a stove, an island and there’s your refrigerator.

There is going to be basically four calculations that we need to do in order to calculate your square footage. Let’s just dive right into it!

First of all, the length from the corner in this particular corner to the end of your current countertop you need to measure that. In my example, I have 120”.  Countertops (by design) are roughly 25.5” deep so I’ve marked that here.

For the corner here, after we turned the corner and head down I want you to measure from the corner to where, in this case, the stove would begin, and I get a measurement in my diagram of 66”.

Stoves traditionally are 30” across. Yours should probably that way as well. In my example, this last piece is 48” wide.

My island currently is 36” deep by 60” long and that’s pretty standard for a small basic island.

Now the math. The first thing we’re going to do is calculate the number of square feet on the left leg of this L. If I take 120” and I multiply it by 25.5”, I’m going to calculate the number of square feet for this piece of the Land that’s perfect.

In my example over here, 120” x  25.5” = 3060 sq. inches. I am going to take you through the calculation to get square inches and then at the end we’re going to turn it into square feet.

For the second piece of the L,  if you remember at the beginning,  I noted that from the corner to the stove we have 66”. Now we’ve already taken 25.5” of that and we’ve accommodated for it on the left leg so we’re going to need to reduce the 66” by 25.5” and that’s going to get us to 40.5”. If we take our 40.5” which is the new distance from here to the stove and we multiply that by our 25.5”,  we’re going to get 1032.75 square inches.

Piece C on the other side of the stove is 48” x 25.5” and that gets us 1224 square inches and then lastly, the island 60” x 36”  multiply those two together to get us to 2160 square inches.

These numbers are large but they are going to get small really quick here.

Once you have your 4 pieces calculated  I’d like you to just add them up and in my example, the total is 7476.75 square inches. Divide that by the number of square inches in one square foot and that’s 144”.  You just take 12” x 12” to get 144” by dividing your total square inches by the square inches in one foot. You are going to get the number of square feet and in this example, we have 51.9 square feet.

That’s the number you need to bring with you when you come to Builder Surplus to get a calculation on how much it’s going to cost to replace your countertops.

The only other things I am going to have you note would be any cutouts. A cutout in this particular example is right here where I have a sink and that’s it for this particular one.

You may have a cooktop cut out but in my example, I have a stove so there is no cut. The only other thing that might be handy to bring with you would be if your island has an overhang where the granite or the quartz extend beyond the edge of the cabinets and how far is the overhang so that we can pretty much do the calculation here.

If your countertop island depth is 36” we’re calculating the overhang to be about 12” but just double-check and make sure and with that a little bit of information it’s that easy with the math that I’ve shown you today.

Maybe with a quick diagram and a calculator you’ll be able to come up with the number of square feet that you need for your countertops!

Custom Countertops: Butcher Block and Concrete

Today, we’re going to talk about a couple of pretty unique and insanely intriguing custom countertops. It’s because of their out-of-the-box design that we love them so much, and I’m pretty sure you’ll come to adore them, too. In this post, I’ll lay it all on the countertop and give you reasons why these particular styles have captured the interest of homeowners across the nation and why they continue to be a hot, trendy style in kitchen and bathroom design. As countertop experts in Louisville, Newport, and Cincinnati, we are here to share our expertise on these two unique countertop options.

Custom Countertops: Butcher Block

There’s no denying it – they’re edgy. I mean, they’re not called custom countertops for nothing. Unlike the typical granite or marble, these countertops have a more creative, quirky feel to them. The butcher block is a natural at maintaining the traditional country home or cottage style kitchen setting, and because of its natural tendencies, it persistently looks fresh, giving the impression that it’s just been cleaned. There’s versatility in them, too! Since it’s made of wood, you can apply any color of stain and compliment the other features in your kitchen or bath to tie everything together. If the color doesn’t grow on you after a period of time or you simply want to switch it up a little bit, there’s a cost-effective way to make that change. Simple, too. Even with a sealed finish, it doesn’t take too much elbow grease to sand down and refinish the butcher block countertop. Then, when you’re done, apply that new color of choice. See, change doesn’t always have to be difficult.

Another thing, I bet you’ve probably already guessed it, but you’ll never need a cutting board again. Depending upon the finish applied to it, you can slice-and-dice all you want on these bad boys with no worry about knife trails. It’s truly a chef’s dream. The longevity of this style is one of its greatest appeals, though. With a simple cleaning solution (water and vinegar), you’ll keep that same shine and finish decades, yes, decades later. Now, if that doesn’t pique your interest, then take a look at the pictures. Nice, right? See what I mean about the different finishes and colors of stain. Listen it’s your house, your kitchen – make it your own with a sleek, unique style like this one! At Builders Surplus, we’re happy to provide you with such a style. Butcher block is a special order product, so please contact one of our designers to discuss your butcher block countertop options.

Custom Countertops: Concrete

Concrete countertops provide a whole realm of possibility. It’s concrete, so it obviously has to be poured. This means you can mold the concrete in any fashion to make it your own. There’s an abundance of really cool, off-the-wall designs that can make a kitchen or bath truly one of a kind. You can mold the edges how you want to. Don’t like hard-cut, 90° angles?  Well, smooth it out, and give your custom countertop the kind of curvature you want! I really appreciate this feature because, if you’re like me, you’ve turned a corner too sharp and been subject to that merciless, pain of the corner jab. But, you’re probably not like me and know your way around a kitchen.

With that said, these custom countertops are incredibly durable and very near impenetrable to common damages including chipping, scratching, and cracking.  The finish protects it from pesky stains, too. Consider it an instant repellant to spaghetti sauce, wine, or grease. The maintenance on these slabs are almost too easy. Warm, soapy water usually does the trick, but if you want to get really crazy, you can use pH cleaner, as well. Either way, this style is designed for simplicity.

While you may think that if you can pour quick dry concrete, you can DIY concrete countertops. Well, that’s probably not the case. While they may seem like an easy DIY project, they are far more complicated to install than you might think. The main concern is getting every single bubble out of the concrete. If you don’t, you risk cracks, which make this stunner more of a bummer. Our suggestion, use a professional. Use reputable sites like Thumbtack or Home Advisor to find reputable installers. You can see reviews from past customers and they have already been vetted by the company.
