Sanded Vs Unsanded Grout For Backsplash? Prices, Installation Cost, Best Brands, Pros and Cons

Choosing the right grout type is a crucial decision when installing a backsplash in your kitchen or bathroom. The debate between sanded and unsanded grout can significantly impact your project’s durability, appearance, and cost. The primary difference lies in their composition – sanded grout contains fine sand particles, while unsanded grout doesn’t. This distinction affects everything from application methods to longevity and price. Understanding these differences will help you make an informed decision that balances aesthetic appeal with practical considerations for your specific backsplash project.

What Is Sanded Grout?

Sanded grout is a cement-based mixture containing fine sand particles. These sand particles provide strength and stability, making it ideal for wider grout lines. Generally recommended for joints 1/8 inch or wider, sanded grout prevents shrinking and cracking in larger spaces. The sand gives it a slightly textured finish that many homeowners appreciate for certain design aesthetics.

The composition typically includes Portland cement, sand, water, and sometimes additional additives for color stability and water resistance. This formulation creates a durable bond between tiles that can withstand significant foot traffic and movement. While primarily used for floor applications, sanded grout can be appropriate for backsplash installations with wider grout lines or when using natural stone tiles that complement its textured appearance.

What Is Unsanded Grout?

Unsanded grout is a smoother mixture that lacks the sand particles found in its sanded counterpart. This type is specifically designed for narrow grout lines less than 1/8 inch wide, which is common in many backsplash installations. Its fine, smooth consistency allows it to fill tiny spaces without shrinking or cracking.

The composition includes Portland cement, powdered limestone, water, and color pigments. Without sand, unsanded grout provides a smoother finish that works particularly well with delicate surfaces like glass, polished marble, or other materials that could be scratched by sanded varieties. This makes it a popular choice for backsplash projects featuring glossy subway tiles, mosaic designs, or other installations with tight, precise grout lines.

Key Differences Between Sanded And Unsanded Grout For Backsplash

Feature	Sanded Grout	Unsanded Grout
Joint Width	1/8 inch or wider	Less than 1/8 inch
Texture	Slightly rough, textured	Smooth, fine
Durability	Higher resistance to cracking	More prone to cracking in wider joints
Shrinkage	Minimal shrinkage	More prone to shrinkage
Scratch Potential	Can scratch delicate surfaces	Safe for polished and delicate surfaces
Water Resistance	Good, needs sealing	Moderate, needs sealing

The width of grout lines is the primary factor in determining which type to use. While backsplashes traditionally feature narrow grout lines favoring unsanded grout, some contemporary designs incorporate wider spacing where sanded grout would be more appropriate. Additionally, the tile material itself should influence your decision – softer or more delicate tiles pair better with unsanded grout to prevent scratching.

Pros And Cons Of Sanded Grout For Backsplash

Pros:

• Superior durability and crack resistance in larger joints
• Better stain resistance than unsanded varieties
• Less shrinkage during curing
• More stable in areas with movement or vibration
• Generally less expensive than unsanded options
• Available in a wide range of colors

Cons:

• Can scratch delicate tile surfaces like polished marble, glass, or metal
• More difficult to work with in narrow joints
• Rougher texture can be harder to clean in kitchen environments
• May be too textured for certain design aesthetics
• Slightly more difficult application process

Pros And Cons Of Unsanded Grout For Backsplash

Pros:

• Safe for delicate and polished surfaces without risk of scratching
• Creates a smoother, more refined finish
• Easier to apply in narrow joints typical of backsplashes
• Better for precision work and detailed patterns
• Smoother surface is easier to wipe clean in kitchen settings
• Ideal for vertical applications as it’s less likely to sag

Cons:

• Not suitable for joints wider than 1/8 inch due to shrinking and cracking risk
• Generally more expensive than sanded grout
• More prone to shrinkage during curing
• Less durable in high-movement areas
• May require more frequent sealing
• Can be more challenging to find in specialty colors

Price Comparison: Sanded vs Unsanded Grout

The price difference between sanded and unsanded grout is notable but not extreme. On average, sanded grout costs between $10-$20 per 10 lb. bag, while unsanded grout typically ranges from $15-$30 for the same quantity. Premium brands and specialty formulations can push prices higher for both types.

Several factors influence pricing, including brand reputation, additives (like antimicrobial properties), color options, and whether the formula includes pre-sealed technology. Epoxy grouts, available in both sanded and unsanded varieties, command premium prices of $40-$100 per unit but offer superior durability and stain resistance for backsplash applications.

For a standard kitchen backsplash (approximately 30 square feet), you might spend $20-$60 on traditional grout materials. However, the slight price premium for unsanded grout is often justified for backsplash applications given its suitability for the typically narrow joints and delicate tile materials used in these installations.

Installation Costs And Considerations

Professional installation costs for backsplash grouting typically range from $2-$7 per square foot for labor, with unsanded grout installation generally commanding prices at the higher end due to the more meticulous work required. A complete backsplash installation, including tiles and grouting, averages $400-$1,200 for a standard kitchen, depending on your location and the complexity of the project.

While the grout type itself has minimal impact on overall installation costs, several factors can influence the final price:

• Removal of existing backsplash ($3-$6 per square foot)
• Complex patterns requiring precise grout application (10-20% premium)
• Special requirements for epoxy grout application (25-40% premium)
• Custom color mixing ($15-$25 additional)
• Grout sealing ($0.75-$2 per square foot)

DIY installation can save on labor costs, but unsanded grout may present a steeper learning curve for beginners due to its quicker drying time and need for precise application in narrow joints. Factor in approximately $75-$150 for quality application tools if pursuing the DIY route.

How To Choose Between Sanded And Unsanded Grout For Your Backsplash

The decision between sanded and unsanded grout should primarily be based on your grout line width. For joints narrower than 1/8 inch, unsanded grout is the clear choice, while wider joints demand sanded grout to prevent cracking and shrinkage.

Consider your tile material carefully. Glass, polished stone, porcelain, and metal tiles are susceptible to scratching and require unsanded grout. More rustic materials like natural stone, ceramic, or concrete tiles can handle sanded varieties without damage.

Your design aesthetic also matters. For sleek, contemporary backsplashes with minimal grout lines, unsanded grout creates a smoother, more refined appearance. Conversely, rustic or traditional designs often benefit from the subtle texture sanded grout provides.

Maintenance requirements should factor into your decision. Kitchen backsplashes frequently encounter splashes and stains. While both types require sealing, unsanded grout generally creates a smoother surface that’s easier to wipe clean, though sanded varieties typically offer better stain resistance.

For most modern backsplash applications featuring subway tiles, mosaics, or other installations with narrow grout lines, unsanded grout remains the industry standard recommendation due to its compatibility with typical backsplash specifications and improved cleanability in kitchen environments.
