What is rectified tile?

Rectified tile undergoes a secondary milling process after firing that saws and polishes each edge to exact, right-angle cuts. This precision manufacturing produces tiles that are dimensionally uniform from piece to piece, enabling installers to set them with minimal spacing between units.

Standard pressed tile, by contrast, comes from the kiln with slightly rounded or irregular edges. These softer edge profiles are a natural byproduct of the pressing and firing process. To accommodate edge variance and prevent chips, pressed tile installations typically require grout joints of 3/8 inch or wider.

Rectified edges allow grout lines as narrow as 1/16 inch to 1/8 inch, creating a more monolithic appearance where the tile surface dominates visually over the grout lines. This tighter joint also means less grout is needed per square foot of installation and reduces the number of grout seams that can trap water or stain over time.

The trade-off is cost: rectified tile carries a premium because of the extra milling step. Installation also demands greater precision in layout and substrate preparation, since the tight tolerances leave less room for slight variations. When working with tile contractors in Tampa, specifying rectified tile typically adds both material and labor costs but delivers a finished appearance with clean, consistent joints.
