For professional labor and materials, it would cost between $6,000 and $28,000 to install 1,000 square feet of Saltillo tile flooring. If that’s out of your budget, you could consider laying the tiles yourself or choosing a less expensive type of flooring. For example, vinyl flooring costs just $2 to $7 per square foot, so for a 1,000-square-foot space, you’d pay $2,000 to $7,000.

A cement backer board is not needed for laying tile on concrete. Sometimes referred to as a cementitious backer unit, or CBU, backer board should be used if the subfloor is plywood or OSB. The backer board provides a base on which to install the tiles that isn’t as likely to be damaged by any accidental water seepage as natural materials would be.

Removing old tiles can be more complicated, but it can also be more manageable, depending on your circumstances. Typically, old tile is hard to remove because the adhesive had loads of time to bond with your wall, becoming a formidable foe between you and your new tile installation project. On the other hand, old tile in high-traffic areas can become loose, making it much easier to remove.

Yes, you can install a backsplash directly onto drywall, provided the wall is properly prepped, clean, and dry. For best results, especially in kitchen areas, your walls should be made of moisture-resistant drywall, often called green board. If your current wall isn't moisture-resistant, it's recommended to replace it before installing the backsplash. For even greater protection against water damage, you can remove the existing drywall and install a tile backer board or cement board instead. While properly installed standard drywall is typically strong enough to support a backsplash, some local building codes may require water-resistant materials in kitchen areas, so it's a good idea to check.
