Mitered edge countertops are usually 2 to 2.5 inches thick. The thickness accounts for the 45-degree angle required to form a seamless corner, resulting in a dramatic and thick-edged appearance.

The least porous countertop material is engineered quartz. Made from a blend of natural quartz and resins, it is non-porous and highly resistant to stains, scratches, and bacteria. This makes quartz countertops exceptionally low-maintenance and durable, ideal for kitchens and bathrooms where hygiene and easy upkeep are priorities. Other non-porous options include solid surface materials like Corian, which also offer excellent resistance to moisture and stains.

Marble countertops are often considered better than limestone because of their superior durability and luxurious appearance. Marble is harder and less prone to scratching and denting, though it still requires maintenance and sealing to prevent stains and etching. Marble is typically more expensive, but its beautiful veining and range of colors offer a high-end look. 

Porcelain countertops have a fairly long life span, sometimes lasting for decades. Depending on how much wear and tear you put your countertops through, it could last 25 to 50 years. But be warned, porcelain is also prone to cracking, so as long as you take good care of it, you’ll have those countertops looking brand new for years to come.
