PORCELAIN VS. CERAMIC TILE: WHICH SHOULD YOU USE WHERE?
Both are clay tiles. Both are fired at high temperature. But the differences in water absorption and density change where each one belongs.
THE TECHNICAL DIFFERENCE
Porcelain is fired hotter (~1,200–1,400°C) from a denser clay. By definition, porcelain absorbs less than 0.5% of its weight in water. Ceramic is fired at lower temperatures from coarser clay and absorbs 0.5–7% — which means it's more porous and more sensitive to moisture and freeze-thaw.
WHERE PORCELAIN WINS
Bathrooms (especially showers and wet areas), kitchens, mudrooms, exterior patios, anywhere with freeze risk, and high-traffic floors. Porcelain is also denser and chips less. For most Kelowna homes, porcelain is the default.
WHERE CERAMIC IS FINE
Wall installations (showers, backsplashes, accent walls) where water absorption isn't a structural concern, low-traffic floors in dry rooms, and budget renovations. Ceramic is typically 20–30% cheaper per square foot.
COST DIFFERENCE
Ceramic tile material: $1–$5 per sq ft. Porcelain tile material: $3–$10 per sq ft. Installation labour is the same for both ($6–$12 per sq ft in Kelowna depending on size and pattern). On a 200 sq ft bathroom floor, the porcelain upgrade adds $400–$800 over ceramic — usually worth it.
LARGE-FORMAT AND RECTIFIED EDGES
Most large-format tile (24" × 48" and bigger) is porcelain because ceramic doesn't hold up at that size. "Rectified" means the edges are precisely cut so you can install with very thin grout lines (1/16"). For a luxury look, large-format rectified porcelain is the standard.
A NOTE ON PEI RATINGS
PEI is the abrasion rating: PEI 3 is fine for residential floors with light shoes; PEI 4 handles heavy residential and light commercial; PEI 5 is for full commercial. Don't install a PEI 1–2 (wall tile) on a floor — it will scratch through the glaze in a year.
