Tile is where art meets architecture—but beauty alone isn’t enough. One of the most important (and most misunderstood) parts of choosing tile is understanding water absorption, tile suitability, and ongoing care. Choosing the right tile for the right application protects your investment and ensures your space ages beautifully.
What Is Water Absorption—and Why Does It Matter?
Water absorption measures how much moisture a tile can take in. The higher the absorption, the more porous the tile. This directly affects where a tile can (and should) be installed.
-
Showers & wet areas require tile that can handle frequent moisture.
-
Kitchen backsplashes deal with splashes, and daily wear.
-
Floors vs. walls experience completely different stress levels.
-
Indoor vs. outdoor applications introduce temperature swings, including freeze-thaw conditions.
Using tile outside of its intended rating can lead to staining, cracking, or long-term damage.
Red Rock Tileworks: Designed for Vertical Indoor Walls
At Red Rock Tileworks, our handmade ceramic tiles are crafted specifically for vertical indoor wall applications—think showers, backsplashes, fireplaces, and statement walls. When installed correctly and in the right environment, they perform beautifully and age with character.
Need something more rugged? We also offer special-order handmade porcelain that’s suitable for outdoor installations, freeze-thaw climates, and even pools—available with an upcharge due to the increased durability and production requirements.
For maximum versatility, our sister company Haustile produces vitrified porcelain tile that’s ideal for walls, floors, indoor, or outdoor use—a true workhorse with design-forward style.
Tile That Requires Ongoing Care
Some tile materials are meant to live—and evolve—over time. Terracotta and natural stone, for example, are inherently porous and require periodic sealing to preserve their integrity.
Sealants help:
-
Protect against moisture absorption
-
Reduce staining
-
Extend the life of the tile
These materials reward attentive care with warmth, patina, and depth—but they’re best suited for clients who appreciate wear and maintenance as part of the material’s story.
A Note on Crackle Glazes
Crackle glazes are exactly what they sound like: intentional fine cracks in the glaze surface that create depth, texture, and visual movement. Over time, these cracks can darken or stain, especially in wet or high-use areas.
This is not a defect—it’s part of the aesthetic. However, crackle-glazed tile should be:
-
Properly sealed
-
Installed with awareness of how it will age. No steam showers.
-
Chosen intentionally for its evolving character
The Bottom Line
Tile isn’t one-size-fits-all. Understanding ratings, water absorption, and care requirements ensures your tile performs as beautifully as it looks.
When in doubt, ask questions. Choose intentionally. And always match the tile to the space it’s meant to live in.
Beautiful tile deserves the right environment to thrive.
