A pizza stone is the cheapest upgrade for homemade pizza. Preheated for 45–60 minutes, it stores heat and transfers it straight into the dough, and its porous surface pulls out moisture. The result is a crisp, browned base instead of a pale, soft one. Below are the best pizza stones for home ovens and grills, plus a replacement stone for Ooni pizza ovens.

How to Choose a Pizza Stone
Cordierite, ceramic or clay?
Cordierite is the standard for pizza stones. It handles sudden temperature changes without cracking and is rated well above any home oven, so it also works in grills and pizza ovens. Glazed ceramic (like Emile Henry) is easier to clean and can be washed with soap, but gives a slightly less crisp base. Clay stones are fine in a home oven but usually carry lower temperature ratings.
Size and shape
Measure your oven or grill first and leave at least an inch of space on every side so air can circulate. Rectangular stones use oven space better and fit bread. Round stones suit classic pizzas. A 15-inch stone handles a 14-inch pizza with room to spare.
Thickness
Thicker stones (0.5–0.75 inches) hold more heat and recover faster between pizzas but take longer to preheat. Thin stones heat quickly but cool off when a cold pizza hits them.
Care
Never use soap on an unglazed stone, and never put a cold stone into a hot oven or splash it with water while it’s hot. Scrape it clean once it has cooled. Stains are normal and don’t affect performance.
Our Pick
For most home ovens, the Unicook 15 x 12 is the best value: thick cordierite, a high heat rating and a low price. If you want something that cleans up easily and looks good on the table, go with the Emile Henry Flame Top. Starting from scratch? The Hans Grill PRO XL set adds a good perforated peel.
