Common stones for the kitchen floor include granite, marble, slate, and soapstone.

Recommended support: Cementitious backer board.

Pros

• Tough and durable.
• You can use over a radiant heat system.

Cons

• Stone might not offer the comfort you’re looking for. It can feel like you’re standing on cold rock (because you are). Consider using mats or throw rugs in work areas.
• You’ll need to apply sealants periodically to prevent stains. 
• Marble can be slippery and dangerous to fall on. The elderly and families with young children may want to consider another type of flooring.
• A light-colored grout in between stone tiles will show stains and dirt.
• The stones may chip, so you should keep extras on hand.
• The color of the stone that arrives at your home may differ from what you choose in the showroom if taken from a different lot. If you have the option, approve the slabs that will become your flooring while they are still at the distributor or manufacturer.
