Porcelain Tile FAQs

Everything you need to know about porcelain tile itself: how it differs from ceramic, how tough it really is, and why it performs so well in South Florida homes.

What is the difference between porcelain and ceramic tile?

Porcelain is made from finer clays fired at higher temperatures, making it denser, harder, and far less absorbent than standard ceramic. That density means better durability, better stain resistance, and suitability for floors, walls, and even outdoor use where ceramic often falls short.

Is porcelain tile durable enough for high-traffic areas?

Yes. Porcelain is one of the most durable flooring materials available and handles entryways, kitchens, hallways, and commercial-level foot traffic without wearing through. Its color and pattern are fired into an extremely hard surface that shrugs off daily abuse.

What does a PEI rating mean on tile?

PEI is a simple wear rating from 1 to 5 that tells you how much foot traffic a tile's surface can handle: low numbers for walls, middle for residential floors, and 4 to 5 for heavy residential and commercial traffic. Most quality porcelain floor tile rates 4 or 5, so it works anywhere in a home.

Does porcelain tile absorb water?

Barely. True porcelain absorbs less than 0.5% of its weight in water, which is why it resists staining, handles wet areas like showers, and will not degrade in humid conditions. This ultra-low absorption is the technical line that separates porcelain from ordinary ceramic.

What are rectified edges on porcelain tile?

Rectified tiles are mechanically ground after firing so every edge is perfectly straight and every tile is exactly the same size. This allows tight, thin grout joints and the clean, seamless look most of our imported porcelain collections are designed for.

Should I choose polished or matte porcelain tile?

Polished porcelain delivers a glossy, reflective, high-end look that is beautiful on walls and lower-traffic floors, while matte finishes hide footprints and offer more grip underfoot. Many homeowners use matte on floors and polished on walls; ordering free samples of both is the easiest way to decide.

Is porcelain tile slippery when wet?

It depends on the finish. Matte, textured, and grip finishes provide meaningful slip resistance for bathrooms, pool surrounds, and exterior areas, while polished surfaces are best kept to walls and dry zones. Tell our team where the tile is going and we will point you to appropriate finishes from our 138 collections.

Can porcelain tile be used outdoors?

Yes, porcelain is an excellent outdoor material because it absorbs almost no water and will not fade in sunlight. Choose a matte or textured finish for patios, walkways, and pool decks so the surface stays safe when wet.

Is porcelain tile good for Florida heat and humidity?

Porcelain is arguably the ideal Florida flooring: it stays cool underfoot, is unaffected by humidity, will not warp or swell like wood, and resists mold and mildew because it absorbs virtually no moisture. That is a big part of why tile dominates South Florida homes and condos.

Can you install porcelain tile over radiant floor heating?

Yes, porcelain is one of the best surfaces for radiant heat because it conducts and holds warmth efficiently and is dimensionally stable through temperature changes. Your installer simply follows the heating system manufacturer's guidelines for the mortar and membrane build-up.

How thick is porcelain floor tile?

Most porcelain floor tile runs roughly 8 to 10 millimeters thick, with some large-format pieces slightly thicker for added strength. Check the specifications on each product page, and account for tile-plus-mortar height when matching adjacent floors.

Does porcelain tile fade in sunlight?

No. Porcelain's color is created with mineral pigments fired at extreme temperatures, so it is UV-stable and will not fade even in sun-drenched Florida rooms or outdoor applications. That makes it a safer long-term choice than many woods, vinyls, and carpets near big windows.

Does porcelain tile stain easily?

No. Because porcelain is nearly non-porous, wine, coffee, oil, and pet accidents sit on the surface instead of soaking in, and they wipe up with ordinary cleaners. Unlike natural stone, porcelain never needs sealing to stay stain-resistant.

Can porcelain tile be scratched?

Porcelain is harder than nearly anything in a home, so normal foot traffic, furniture, and pet claws will not scratch it under everyday use. Dragging heavy appliances or grinding in abrasive grit can mark any surface, so use felt pads and keep entry mats at exterior doors.

Why is imported porcelain tile considered higher quality?

Imported porcelain, particularly from established European producers, tends to feature tighter sizing tolerances, rectified edges, more realistic printing, and more refined finishes. All 138 porcelain collections at The Tile Store are imported, and you can judge the difference in person at our Fort Lauderdale showroom or with free shipped samples.
