Tile flooring offers endless design possibilities, from natural stone to ceramic, porcelain, or glass tile. But one often overlooked detail can make or break the look of the entire installation—grout. Grout not only holds the tiles in place but also influences the overall style, durability, and maintenance of the floor. With so many grout options available, it’s important to understand which one best fits the space, lifestyle, and tile selection.
The role of grout beyond the basics
Grout does more than just fill the spaces between tiles. It provides structural stability, protects edges, and prevents moisture from seeping underneath the flooring. Additionally, grout color can highlight or soften the visual effect of tile patterns. Choosing the wrong type can lead to cracking, discoloration, or constant upkeep—issues homeowners want to avoid.
Sanded grout: durable and traditional
Sanded grout is the most commonly used type, especially for floors. It contains sand particles that make it more resistant to shrinking and cracking. This option is ideal for wider grout joints—usually 1/8 inch or larger.
-
Best for: Ceramic or porcelain floor tiles with wider joints
-
Pros: Strong, affordable, and widely available
-
Cons: Rough texture may scratch delicate surfaces like glass or polished stone
Unsanded grout: smooth and sleek
Unsanded grout has a finer texture since it does not contain sand. This makes it easier to apply in tighter grout joints, typically less than 1/8 inch. It’s often chosen for walls, shower enclosures, and smaller decorative tiles.
-
Best for: Glass, marble, and polished stone tiles with narrow joints
-
Pros: Smooth finish, won’t scratch delicate tiles
-
Cons: Less durable for flooring, prone to shrinkage if used in wide joints
Epoxy grout: high performance for modern living
Epoxy grout is made from epoxy resins and hardeners, creating a stain-resistant, waterproof, and highly durable grout. It is more expensive but requires less maintenance than cement-based grouts. Perfect for kitchens, bathrooms, or anywhere spills and moisture are common.
-
Best for: High-moisture or high-traffic areas, such as bathrooms, kitchens, and commercial spaces
-
Pros: Extremely durable, stain- and chemical-resistant, no sealing required
-
Cons: Higher cost, more difficult to install, shorter working time for application
Furan grout: the industrial-grade option
Furan grout is similar to epoxy but uses alcohol-based polymers, making it even more resistant to chemicals and extreme environments. Because of its complex installation process, it’s rarely used in homes and more common in commercial kitchens or laboratories.
-
Best for: Industrial settings with heavy chemical exposure
-
Pros: Superior strength and chemical resistance
-
Cons: Expensive, requires professional installation, limited residential application
Choosing the right grout color
Beyond the type of grout, color plays a major role in the final appearance of the flooring. A matching grout color creates a seamless look, while a contrasting color makes each tile stand out. Neutral tones remain timeless, while bold colors can transform the style into something striking and modern. Homeowners should always test a small section first, as grout color can dry differently than expected.
Sealing grout: an important step
Most cement-based grouts, whether sanded or unsanded, require sealing to protect against moisture and stains. Epoxy and furan grouts are naturally resistant and don’t need sealing. Skipping this step on traditional grout can lead to discoloration, mold growth, or premature damage.
Let’s create a flooring look that’s perfect for your home
The best grout depends on the type of tile, the width of grout lines, the location of installation, and lifestyle needs. For instance, a busy family kitchen may benefit from epoxy grout, while a decorative backsplash with glass tile would do best with unsanded grout. Paying attention to both function and aesthetics ensures the flooring looks beautiful and performs well for years to come.
