Choosing the right kitchen countertops for your home involves doing some homework. You have to be sure that your choice fits your budget, style, and countertop usage. Quartz and granite cost from $20 to $150 per square foot. Marble and stainless steel run from $75 to $250 per square foot. Quartz and granite are resistant to heat and do not scratch easily. Stainless steel, on the other hand, is heat resistant but scratches easily. Marble does not scratch easily, but can be damaged by high temperatures and can be stained by spills. Marble is not recommended for people who do a lot of food prep and cooking. One of the benefits of quartz is that it does not need to be sealed like granite or marble. Quartz is clean and easy to take care of. Granite can be expensive, but it depends on what grade you get and who you purchase from. Remember, style is very important because what you choose must blend in with your existing kitchen decor. Finally, shop around--compare prices for materials and installation and you'll have the countertop that's perfect for you.
