Rectified tile is tile that's mechanically ground after firing to achieve precise, uniform dimensions and perfectly square edges. That precision allows it to be installed with much narrower grout joints, sometimes as tight as 1/16 inch, creating the sleek, nearly seamless look popular in modern design. This guide covers how rectified tile differs from standard tile and what to know before choosing it. For more definitions like this, browse our Tile Glossary.
Rectified vs. Non-Rectified Tile
Non-rectified tile, sometimes called "cushioned edge" tile, has a slightly rounded or irregular edge straight out of the kiln. These small variations require wider grout joints (typically 3/16 inch or more) to look even. Rectified tile's precisely squared edges allow for a much tighter, more uniform layout instead.
Benefits of Rectified Tile
- Narrow grout lines: A clean, modern, nearly seamless appearance.
- More tile visible per square foot: Less area taken up by grout, showcasing more of the tile's pattern or color.
- Ideal for large-format tile: Precision pairs especially well with oversized tiles and slabs.
- Easier pattern matching: Consistent sizing simplifies aligning patterns across multiple tiles, like continuous wood-look planks.
Drawbacks of Rectified Tile
- Requires a flatter substrate, since narrow grout joints leave little room to hide an uneven surface.
- Sharper edges are more prone to chipping during handling and installation.
- Typically costs more than non-rectified tile.
- Less forgiving to install, narrow grout joints leave little margin for error.
Installation Tips for Rectified Tile
- Make sure the substrate is as flat as possible, self-leveling compound is often needed for uneven floors.
- Use tile leveling clips or spacers designed for narrow grout joints to minimize lippage.
- Confirm your grout is appropriate for the joint width, unsanded grout is typical for very narrow rectified joints.
- Consider a professional installer, since a clean result with minimal grout lines leaves little room for error.
The Bottom Line
Rectified tile offers a precise, modern look with minimal grout lines, but requires a more meticulous installation process. Browse Belk Tile's floor tile collection or explore the full Tile Glossary for more terms.
