When installing new tile, most of the attention naturally falls on the tiles themselves—the style, color, and texture. Yet, grout plays an equally important role in both the performance and the overall look of a tiled floor. Choosing the right grout type can determine how well your floor withstands daily wear, how easy it is to clean, and even how polished or seamless the final design appears. With several options available, each suited for specific applications, understanding the differences is key to making the best decision for your home.
What exactly is grout and why does it matter?
Grout is the material used to fill the joints between tiles, holding them firmly in place while preventing dirt, moisture, and debris from slipping through the gaps. Beyond its functional role, grout also impacts the appearance of a tile floor, either blending seamlessly with the tile or creating a bold contrast. A well-chosen grout enhances durability, reduces maintenance, and can transform a tile installation into a showpiece.
Unsanded grout: best for delicate finishes
Unsanded grout is smooth and free of gritty texture, making it perfect for narrow joints that measure less than 1/8 inch wide. It’s often used with delicate tiles like polished marble or glass, where sand could scratch the surface. Because it’s finer, unsanded grout provides a sleek, clean finish, though it can shrink slightly when drying, so careful application is essential.
When to choose unsanded grout
-
Small grout lines under 1/8 inch
-
Polished or easily scratched tiles
-
Vertical surfaces like bathroom walls or backsplashes
Sanded grout: durable and versatile
For joints 1/8 inch to 1/2 inch wide, sanded grout is the go-to option. The sand particles mixed into the formula help prevent shrinking and cracking, making it highly durable for high-traffic areas like kitchens, hallways, or living rooms. It’s more affordable than many specialty options and comes in a wide variety of colors, allowing for plenty of design flexibility.
Pros of sanded grout
-
Strong and resistant to cracking
-
Works well for larger grout lines
-
Economical and widely available
Potential drawbacks
Because of its gritty texture, sanded grout isn’t ideal for polished stone or glass tiles. It may scratch the surface if not applied carefully.
Epoxy grout: maximum strength and stain resistance
Epoxy grout is a premium option known for its outstanding durability and resistance to stains, moisture, and chemicals. Unlike cement-based grouts, epoxy grout doesn’t require sealing, making it ideal for areas exposed to water or spills—think bathrooms, showers, and kitchens. Its strength makes it suitable for both residential and commercial applications.
Why epoxy grout stands out
-
Completely waterproof and stain-resistant
-
Doesn’t shrink, crack, or discolor over time
-
Low maintenance compared to traditional grouts
However, epoxy grout can be more challenging to work with due to its quick setting time and higher cost. Many homeowners prefer to have it installed by professionals for best results.
Choosing grout color: subtle or bold?
Beyond the type of grout, color plays a major role in design. A matching grout color creates a seamless, understated look, letting the tile itself take center stage. On the other hand, contrasting grout emphasizes the tile shape and pattern, adding dimension and visual interest. Neutral shades like gray, beige, and white remain popular choices, but darker tones can add drama while helping to disguise dirt.
Which grout is right for your project?
The best grout option depends on the type of tile, the size of the grout joints, the room where it’s being installed, and the desired look. For everyday spaces with standard ceramic or porcelain tiles, sanded grout offers durability and affordability. For luxurious stone or glass finishes with tight joints, unsanded grout ensures a scratch-free finish. And for wet or stain-prone areas, epoxy grout provides unmatched performance.
Though often overlooked, grout has a big impact on both the beauty and lifespan of tile flooring. By carefully considering the type of tile, the size of the grout lines, and the demands of the space, homeowners can choose a grout that not only holds tiles in place but also enhances their overall design.
