Marazzi’s Zellige Isn't What You Think — And That's a Good Thing
When I first started reviewing tile spec sheets for commercial projects, I assumed handmade-look tile was just a style category — a surface treatment you could apply to any ceramic body. I was wrong. Marazzi's Zellige collection changed what I look for in a tile, and it forced me to update a lot of my old assumptions.
I'm a quality and brand compliance manager in building materials. I review roughly 200 unique product lines a year. In Q1 2024 alone, I rejected about 18% of first deliveries for specification deviations — caliper variation outside tolerance, inconsistent rectification, glaze issues. I don't just read brochures. I check actual product against claimed specs.
So when I say that Marazzi's Zellige tile is different, I mean it in a way that affects how you specify, how you install, and what you expect the finished wall to look like — not just what color it is.
The Zellige Misconception
The assumption among many designers is that Zellige tile's charm is its irregularity — the handcrafted look with slight variations in color and glaze. That's true, but it's only half the picture. People think that Zellige's appeal comes entirely from glaze variation. Actually, the underlying body consistency is what makes the irregularities feel intentional rather than sloppy.
In 2023, I ran a blind test with our in-house design team: two Zellige-style tiles from different manufacturers, side by side. Over 70% identified the Marazzi piece as “more premium” — without knowing which was which. The difference wasn't in the surface color. It was in the tile body. Marazzi's Zellige uses a consistent, dense porcelain body, even though the surface is artisanal. The competitor's tile had a less controlled body, which made the glaze variations look like defects rather than deliberate character.
That distinction matters when you're specifying for a 50,000-unit apartment complex or a high-end hospitality lobby. The visual charm is in the top layer. The long-term performance is in what's underneath. And the Marazzi showroom at Sukhumvit 39 in Bangkok is the best place I've found to see that difference in person — because they display the tile with different lighting angles, so you can actually see how the body and glaze interact.
Outdoor Showers and the Tile That Survives Them
One of the most interesting conversations I had at that showroom was about outdoor showers. Not a typical application in Bangkok's climate — everyone has indoor bathrooms, right? But it turns out there's a surprising demand for outdoor shower enclosures in tropical luxury developments and pool-adjacent bathrooms. And ceramic wall tile isn't always the first material people consider for those spaces.
To be fair, natural stone looks great in an outdoor shower. But water and stone have a complicated relationship. Over time, water can cause efflorescence, staining, and surface erosion — especially in hard-water areas. Porcelain tile, particularly full-body porcelain, handles that better. The water absorption rate for Marazzi's outdoor-rated porcelain is below 0.5%. That's well under the ASTM C373 standard of 3% for impervious tile.
I'm not saying stone is wrong. But if you're specifying for a project where the shower will actually get used — not just photographed — you need to think about maintenance. The owner gets to pay for cleaning and sealing stone every year. Or they get to hose down glazed porcelain and walk away. That's a decision that shows up on the operating budget, not just the construction budget.
Honestly, I'm not sure why more designers don't specify glazed porcelain for outdoor wet areas. My best guess is that they associate “ceramic” with “indoor.” But the technology has evolved significantly since 2020. The bodies are denser, the glazes are UV-stable, and the slip resistance — measured by dynamic coefficient of friction — is now documented on spec sheets they can actually read.
The Adhesive Remover Problem No One Talks About
Here's something I learned the hard way: specifying the right tile is only half the battle. The other half is what you stick it with. And when you're talking about removal — whether for a renovation or a specification correction — adhesive remover compatibility becomes a real issue.
In Q1 2023, I had to reject a shipment of tile for a luxury condo because the contractor used a rapid-set mortar that wasn't recommended by the manufacturer. The bond was strong — maybe too strong. When we needed to remove a section due to a layout error, the removal process damaged the tile surface. The tile itself was fine. The adhesive remover was the problem. It was too aggressive for the glaze on that specific tile.
The way I see it, you have two choices: specify the adhesive and remover alongside the tile, or accept that someone else will make that decision under time pressure. I've seen what happens with the second option — it usually costs the project 15-20% of the tile budget in waste and rework. For a $50,000 tile order, that's real money.
Marazzi's technical documents actually include adhesive compatibility recommendations. That's rare in the tile industry. Most suppliers leave that to the contractor. A manufacturer that lists recommended adhesives for each product line is telling you they've done the testing. That's worth the price of admission.
What a Pizza Stone Has to Do With Tile
I get why people Google “what is a pizza stone” and end up on a tile website. The thermal properties are similar — ceramic holds heat. But here's the distinction: tile is not a cooking surface unless it's specifically rated for that. Pizza stones are unglazed ceramic. Most wall and floor tile is glazed. The glaze can contain heavy metals not intended for food contact at high temperatures.
I've had architects ask me if they can use leftover tile as a pizza stone. The answer is: unless the tile is specifically labeled as food-safe and heat-rated for that purpose, don't. Marazzi doesn't market tile as pizza stones, and for good reason. The product is engineered for walls and floors, not for cooking. Use a real pizza stone. The tile is for your kitchen backsplash — not your pizza.
The Real Bottom Line
I get why some contractors stick with what they know — thinset, stone, standard rectified tile. It's comfortable. The fundamentals haven't changed: you still need good substrate prep, correct expansion joints, and proper grout. But execution has transformed: tile bodies are more engineered, glazes are more durable, and manufacturers like Marazzi are publishing technical data that allows you to specify with confidence — if you take the time to read it.
A showroom visit isn't just about picking colors. It's about understanding the product's real-world performance: how it handles moisture, what adhesive it needs, how it'll survive a renovation. The Marazzi showroom at Sukhumvit 39 in Bangkok is one of the few places I've seen that allows you to test those parameters. That's worth a trip, even if you're just starting the specification process.
The industry is evolving. Your specification approach should too.
