Ceramic tiles come in standard thicknesses of 1/16 , 5/16, or 1/4 of an inch. Of course, the thicker the tile is, the heavier it gets. Thickness and weight are key factors in determining your countertop’s weight, so choose carefully.
1/16 inch
The thinnest ceramic tiles in the market, 1/16-inch tiles are more ideal for the walls rather than the main countertop surface. They cannot support heavy weights and may easily shatter from impact. They make great and attractive backsplashes and front guards. They are also light and easy to install. You can usually mount these ceramic tiles on your own. Just make sure to use the right type of adhesive, which is epoxy grout. This serves both as a binder between each tile and between the tile and the countertop base.
5/16 inch
These are the most commonly used ceramic tiles for countertops, mostly because they are the thickest and most durable type available. They are ideal as the main countertop surface because they can support heavy kitchen equipment and can handle the heat generated during operation. They are moderately heavier than other thicknesses, so they are not advisable for wall applications. Despite their weight, however, they are still easy to install and can be installed without professional help.
1/4 inch
Quarter-inch ceramic tiles are slightly thinner than 5/16-inch ones, but they offer almost the same degree of durability. They can be used for both wall and surface mounting, and are often used as flooring at the base of the counter. They work well in all kitchen and bathroom sizes.
Weight
Ceramic tiles are heavier usually heavier since they are denser than other materials for countertops. The thickness and size of a ceramic tile usually determines its weight, so a quarter of an inch thick ceramic tile that is only four inches by four inches may be lighter than a ceramic that has the same thickness but larger surgace area.
Lighter ceramic tiles are ideal for the walls of your countertop since they are less likely to fall since the mortar will be able to support these tiles. These lighter tiles are usually easier to install and may no longer need the help or supervision of a professional.
Heavier ceramic tiles are ideal for the surface area and flooring of your countertop since they can withstand and support heavy objects that are placed on them. These heavy tiles should not be used for the walls of the countertop since they may fall down while waiting for the mortar to dry. Furthermore, be sure that the foundation of your countertop is reinforced well to prevent the entire sturcture from giving in to the weight of the tiles.
You may need to hire a professional to help you install these heavy tiles. It is best to first consult you contractor regarding how thick and heavy a ceramic tile should be for your countertop.
