While exploring Coverings 2025, one couldn’t help but notice the dominance of massive porcelain slabs featured in countless booths. These slabs adorned walls, floors, counters, and more—both indoors and outdoors. Discover why this material is surging in popularity and why homeowners are choosing it over marble and natural stone.
What Are Large-Format Porcelain Slabs?
Porcelain is no stranger to homes, appearing in dinnerware, tiles, sinks, and toilets. Celebrated for centuries as a durable and elegant material, its applications continue to expand. Originating in Europe and now popular in American homes, porcelain slabs are akin to tiles but on a grand scale. Measuring up to 10-by-5 feet (or larger via custom orders) and just 6–12 mm thick, they combine lightweight practicality with striking aesthetics.
“Most tile on the market today is good quality, so it’s really the format that sets one tile apart. Large-format thin tiles can mimic slabs or tiles, ideal for flooring without the bulk of natural stone.”
Manufactured in high-tech facilities using automated processes, these slabs deliver bold, seamless designs that natural stone cannot match.

Porcelain’s slim profile (6–12 mm) makes it lighter and easier to install than marble slabs, which can be up to 3 inches thick. Marble requires labor-intensive installation, including a 2–3-inch deck mud layer, and cannot be placed over existing surfaces. Porcelain’s density also resists stains and UV damage, eliminating the need for sealants.
“Installers love it. It’s easy to cut and install—if you know what you’re doing.”
Cost Comparison:
- Porcelain: $8–$15 per square foot
- Marble: $9–$24 per square foot
While marble remains a timeless choice, porcelain’s versatility, durability, and modern appeal make it the standout option for contemporary homes.
