Ceramic and Porcelain: The Same Family, Different Strengths
Ceramic and porcelain are both fired-clay surfaces, but they behave differently on a project. The short version: porcelain is denser, absorbs almost no water, and handles heavy traffic and outdoor use; ceramic is lighter, easier to cut, and a great value indoors. Knowing which to specify saves money and callbacks.
The One Number That Matters: Water Absorption
Porcelain is fired hotter from finer clay, so it absorbs less than 0.5% water. That makes it frost-proof, stain-resistant, and suitable for facades, wet areas and floors. Ceramic absorbs more (typically 3–10%), which is fine for walls and low-traffic indoor floors but not for exteriors or freezing climates.
Where Each One Shines
- Porcelain — large-format kitchen and bathroom surfaces, commercial floors, ventilated facades, outdoor terraces, and countertops that mimic marble at a lower maintenance cost.
- Ceramic — feature walls, splashbacks, residential wall tiling, and budget-conscious indoor floors.
Browse large-format options in the porcelain slabs catalog and the ceramic slabs catalog.
Finishes That Change the Room
Both come in matte, polished, textured and concrete-look finishes. Matte hides fingerprints and adds grip underfoot; polished reads as luxury but shows wear on high-traffic floors. For slip resistance around pools or entries, specify a textured porcelain.
Cost and Sourcing
Ceramic is usually cheaper per square metre; porcelain earns its premium in durability and lower lifetime maintenance. When sourcing, ask suppliers for the water-absorption class, the rectification tolerance (for tight grout lines on big slabs), and the available slab sizes.
Design Them Before You Order
The fastest way to compare surfaces is to see them side by side. Drop ceramic and porcelain swatches next to your stone, wood and textile choices on a Slab Site moodboard before committing to a supplier.
