Question 1

What is the main difference between ceramic and porcelain tile?

Accepted Answer

Porcelain is fired at higher temperatures and made from denser clay, resulting in a water absorption rate below 0.5% (compared to ceramic's 3–7%). This makes porcelain significantly more resistant to water penetration, staining, and cracking under freeze-thaw cycles. Porcelain is also harder and more durable, but more difficult to cut.

Question 2

Which tile is better for a bathroom floor — ceramic or porcelain?

Accepted Answer

For bathroom floors, we recommend porcelain. Its lower water absorption rate means it handles the constant moisture exposure of a bathroom floor better over time. For bathroom walls above the waterline, ceramic is perfectly adequate and more cost-effective.

Question 3

Is porcelain tile worth the extra cost?

Accepted Answer

For floors, showers, and any area with direct water exposure — yes. Porcelain's durability advantage is real and measurable over a 10–20 year period. For bathroom walls that don't get direct water exposure, ceramic is a smart way to save money without sacrificing quality.

Question 4

What does the PEI rating mean for tile?

Accepted Answer

The PEI (Porcelain Enamel Institute) rating measures a tile's resistance to surface wear. PEI 1–2 is for wall use only. PEI 3 is for light residential floors. PEI 4 is for standard residential and light commercial floors. PEI 5 is for heavy commercial use. For bathroom floors, we recommend PEI 4 or higher.

Question 5

Can I use large-format tile in a small bathroom?

Accepted Answer

Yes — and it often looks better than small tile in a small bathroom. Large-format tile (24×24 or 24×48) creates fewer grout lines, which makes a small space feel larger and cleaner. The key is proper subfloor preparation to ensure the large tiles don't crack.
