Countertop Materials Compared: What Works in Florida

Is granite or quartz better for Florida humidity?

Both perform well in Florida humidity. Quartz is non-porous, so it never needs sealing and resists moisture and stains. Granite is natural stone that needs periodic sealing to keep liquids out. Choose quartz for the lowest upkeep, or granite for natural variation, stronger heat tolerance and outdoor use.

Humidity itself does not damage either surface. What matters in a Florida kitchen is everything around it: iced drinks that sweat, citrus, cooking oil and a lot of entertaining. Sealed granite countertops shrug those off when spills are wiped promptly. Quartz countertops shrug them off with no sealing at all, as long as hot pans go on a trivet.

What is the difference between quartz and quartzite?

Quartz is engineered: roughly 90 to 95 percent ground quartz bound with resins, so it is non-porous and never needs sealing. Quartzite is natural stone formed when sandstone metamorphoses under heat and pressure. It tolerates heat better and holds its color outdoors, but it needs periodic sealing. Quartz offers uniform patterns, while every quartzite slab is one of a kind.

The names cause a lot of confusion at the counter. A simple way to remember it: quartz is made in a factory, quartzite is cut from a quarry. If you want the most consistent look and the least maintenance, quartz wins. If you want natural movement and a surface that can live on a sunny lanai, quartzite countertops are the better fit.

Is quartz heat proof?

No. Quartz tolerates everyday cooking heat, but its resin can scorch, discolor or crack when a hot pan goes straight from the burner to the counter, so use trivets. Granite, quartzite and porcelain handle heat better. If you cook often and set pans down without thinking, compare those materials before you choose.

Slow cookers, electric griddles and air fryers that run for hours can also warm one spot of quartz for a long time. A trivet or cutting board under them is a small habit that protects the surface for years.

Is marble a bad idea for a kitchen?

Not if you know what to expect. Marble is beautiful but softer and porous. Acids such as lemon juice, wine and vinegar can etch the surface, and it needs regular sealing. Many homeowners accept the soft patina that develops over time. If you want a similar look with more durability, consider dolomite or quartzite.

Marble countertops shine in bathrooms and baking areas. Dolomite countertops give a marble look with a little more toughness, and quartzite goes further still.

Which countertop is best for an outdoor kitchen in Florida?

Sun, heat and rain decide this one. Porcelain is UV stable and non-porous, and granite is a long proven outdoor stone. Quartzite also holds up well. Quartz is not recommended in direct sun, and marble and dolomite are best kept under a covered lanai.

How do I choose?

Start with how you live, then fall in love with a slab. Browse the stone catalog, shortlist two or three colors, and see them in person at our Nokomis showroom. When you are ready, request your countertop estimate.
