Tile Thickness Matters: Design Smarter with the Right Specs

When it comes to commercial tile specification, an element often overlooked yet essential to project success is tile thickness. While surface aesthetics and slip resistance typically take center stage, understanding how tile thickness affects installation requirements, performance, and long-term durability is equally critical.

For commercial interior designers, contractors, and national brand account managers, selecting the wrong tile thickness can result in increased costs, schedule delays, or even safety issues. At Creative Materials, our mission is to help our clients design and build better communities by simplifying the selection and supply of surface materials. This includes helping you select the right tile thickness for each commercial design scenario.

In this blog, we’ll explore various tile thicknesses, their impact on performance, and the best project applications for each, all while providing you with tools to avoid costly missteps.


Why Tile Thickness Matters

Performance Requirements Vary by Application

Thinner tiles may be adequate in vertical applications, but floors in high-traffic commercial environments, such as airports, restaurants, or big-box retail, require thicker tiles. Choosing the correct thickness ensures:

  • Reduced breakage or failure under weight
  • Longer-lasting installations
  • Compliance with performance standards

Substrates & Transitions Depend on Thickness

The thicker the tile, the more it can affect:

  • Substrate buildup
  • Transition heights to adjacent flooring types
  • Overall floor elevation tolerances

When tile thickness isn’t accounted for during design development, your contractors may face job-site conflicts or, worse, the need for rework.

Schedule & Budget Impacts

Selecting an inappropriate thickness can create downstream issues in procurement and installation. By understanding how thickness plays into material logistics, you can protect project timelines and budgets.


Exploring Tile Thicknesses

Let’s explore the most common thicknesses and where they shine:

Gauged Porcelain Panels (GPPs) | 3.5mm up to 7mm

Transform your vision into a breathtaking reality. Gauged Porcelain Panels deliver sleek, uninterrupted surfaces that evoke elegance, sophistication, and modernity. With expansive formats and minimal grout lines, they create a refined, monolithic aesthetic, the kind of seamless finish that turns everyday spaces into architectural statements.

Best For: Large-scale wall applications, column wraps, elevator lobbies, and decorative feature walls where first impressions matter most.

Why Designers, Contractors and Brands Love It:

  • Striking scale that elevates any environment
  • Lightweight and versatile for creative freedom
  • Cost-effective luxury
  • Quicker installation due to large format

Installation Note: Requires flat substrates, specialized handling, and certified installers—but the end result is worth every detail.

Picture a space where walls flow uninterrupted, wrapping guests in a sculptural, immersive experience. With Gauged Porcelain Panels, you’re not just finishing a surface, you’re crafting a masterpiece that exceeds expectations.”

Standard Porcelain Tile | 8mm up to 11mm

When your goal is to create enduring beauty that performs under pressure, standard tile thickness delivers. These porcelain tiles, ranging from 8mm to 11mm, are the trusted workhorses of commercial design, offering a perfect blend of strength, style, and simplicity.

Standard thickness helps you confidently achieve both vision and value. It supports seamless design continuity across projects while keeping installation straightforward and budgets in check.

Best For: Every day, in high-traffic environments where design integrity and long-term durability matter, such as corridors, retail floors, restrooms, and back-of-house areas. Whether your project is a bustling workplace, an inviting retail destination, or a fast-paced restaurant, standard thickness tile can handle it all.

Why Designers, Contractors and Brands Love It:

  • Versatile for nearly every application
  • Easy to source and install, helping keep projects on schedule
  • Compatible with a wide range of setting materials and techniques

Smart Considerations: Be mindful of transitions to thicker tiles, especially when mixing materials from different collections or formats. Early coordination ensures clean lines, smooth surfaces, and uninterrupted design flow across every zone of the space.

This is more than just a specification; it’s a dependable solution that supports beautiful, functional, and future-proof commercial spaces.

Pavers | 20mm

When your project moves outdoors—or into high-impact zones—strength isn’t optional; it’s essential. Enter 20mm pavers: the ultimate solution for commercial environments where performance meets possibility.

From rooftop retreats and outdoor dining spaces to drive-up entryways and luxe lobbies, paver tiles are designed to thrive where others fail. With collections offering coordinating thicknesses, you can blur the line between indoors and outdoors, creating a seamless flow throughout the property.

Best For:

  • Rooftop terraces
  • Amenity decks
  • Raised flooring systems
  • Porte-cochère

Why It Works: Pavers are extremely durable, able to hold heavy loads and withstand high foot traffic. Additionally, they are frost-resistant and can be installed using a variety of methods.

Best Practices for Choosing Tile Thickness

Every detail of your commercial design tells a story, including the thickness of the tile. By making thoughtful, strategic choices here, you have the opportunity to protect your project’s integrity, elevate the user experience, and deliver spaces that look stunning and perform beautifully for years to come.

Start with Purpose: Match Thickness to the Use Case

Every space serves a purpose, and your tile should be chosen to match it. Go beyond surface beauty and think about what your space needs to endure. When you specify tile, think about more than just the visual. Consider weight loads, cleaning demands, and foot traffic. This proactive approach protects not only your design but also your budget, timeline, and client satisfaction.

  • High-traffic floors? Prioritize strength and durability with a thicker tile (9mm or greater). These tiles are built to handle the weight and wear of bustling commercial environments, ensuring your design stands the test of time.
  • Feature walls or ceilings? Lightweight, ultra-slim gauged porcelain panels make it easy to create sweeping, dramatic visual statements without overburdening the structure.
  • Outdoor areas? In challenging climates, 20mm pavers deliver peace of mind. Frost-resistant and impact-tough, they’re designed to thrive under the harshest conditions.

Thick Holistically: Layers Matter

Tile doesn’t live in isolation; it’s part of a larger flooring system. Every layer, from the substrate to adhesives to transitions, must work in harmony. Seamless transitions aren’t just an aesthetic choice; they can significantly impact safety, accessibility, and the overall flow of both interior and exterior spaces.

Failing to consider these layers can result in costly fixes later. By embracing a layered mindset, you protect your vision and create spaces that feel cohesive and welcoming for every occupant. The Creative Materials team is ready to elevate your project by expertly guiding you in incorporating these essential layers into your specifications.

What Happens When You Get It Wrong?

Tile thickness isn’t just a number on a spec sheet; it’s a decision that can shape the entire success of your project. Overlooking this critical detail can trigger a ripple effect of challenges that jeopardize your schedule, budget, and reputation.

  • Costly, Irreversible Damage: Cracked tiles. Unsightly lippage. Once installed, these flaws aren’t just visible, they’re expensive to fix. What should have been a smooth, durable surface turns into a costly replacement job and a stain on your project’s quality.
  • Unexpected Delays That Derail Schedules: When the wrong tile thickness is specified, contractors are forced to scramble for last-minute solutions or additional materials. These unplanned adjustments can disrupt construction schedules, delay openings, and leave everyone—from owners to end users—frustrated.
  • Labor Costs That Spiral Out of Control: Extra substrate prep, leveling, or custom transitions all mean one thing: additional labor hours. The result? Budgets that balloon and profit margins that shrink, all because of a detail that should have been addressed upfront.
  • Brand Standards at Risk: For national accounts and branded environments, consistency isn’t optional; it’s essential. Failing to match the right thickness across locations can result in inconsistent aesthetics and functionality, putting your carefully curated brand experience at risk.
