Which Grout To Use For Backsplash

Selecting the right grout for your backsplash is an important decision that will impact the overall look, durability, and maintenance requirements of your backsplash installation. With so many grout options on the market, it can be confusing to determine which one is best suited for your needs. This article will examine the pros and cons of different grout types to help you choose the right grout for your backsplash project.


Grout serves both practical and aesthetic purposes in tile installations. It fills the joints between tiles, sealing and holding them in place. Grout also contributes to the overall visual appeal of the backsplash. With such an expansive array of grout colors, textures, and performance characteristics available, selecting the optimal grout requires careful consideration of the backsplash location, tile type, and desired aesthetic.

When weighing grout options, keep these factors in mind:

  • Location: Backsplashes in kitchens and bathrooms have more exposure to water, grease, and potential staining than other areas. A grout with maximum stain and water resistance is ideal.
  • Tile material: Natural stone, glass, and metal tiles have different sealing requirements than ceramic or porcelain. Some grout types may stain porous, unsealed surfaces.
  • Color: From bright white to earthy neutrals, grout color impacts the overall look and feel of the backsplash.
  • Texture: Grout comes in smooth and textured finishes. Textured grout provides grip and a classic handcrafted appearance.
  • Budget: While cost should not be the only deciding factor, inexpensive grout options can provide good performance on most backsplashes.

By weighing all of these factors, it becomes easier to narrow the options and select the best grout for your backsplash installation.

Best Grout Options by Backsplash Location

Kitchen Backsplash Grout

Kitchen backsplashes demand grout that can withstand exposure to water, oils, food stains, and daily wear and tear. Epoxy or urethane grout provide ultimate protection, while sanded grout offers budget-friendly durability. Opt for neutral shades like white or light gray to conceal potential stains.

Bathroom Backsplash Grout

In bathrooms, moisture resistance is essential. Epoxy and urethane grouts deliver waterproof, stain-resistant performance. If using natural stone tiles, unsanded grout prevents abrasion and scraping. White grout keeps a crisp, clean look against ceramic or porcelain tiles.

Living Space Backsplash Grout

Backsplashes in living spaces and accent walls have lower risks of stains and water exposure. Sanded grout offers versatile, economical performance for most applications. From bright whites to earthy beiges, grout color can be selected based purely on aesthetics without the need for maximum stain protection.

Grout Maintenance Tips

Proper care and sealing is crucial for all grout types. Here are some tips:

  • Seal grout with a penetrating sealer every 1-2 years.
  • Sweep or vacuum grout joints regularly to prevent buildup.
  • Use neutral pH cleaners and avoid harsh alkaline or acidic cleaners.
  • Re-apply grout into cracked or worn areas to maintain waterproofing.
  • Do not allow spills or stains to set; blot immediately.

Choosing the Right Grout Color

Grout color impacts the look and feel of the backsplash and entire kitchen or bathroom. Here are popular options:

  • White provides a clean, bright look alongside ceramic, porcelain or glass tiles in bold colors or patterns.
  • Gray offers a modern, sleek look. Dark charcoal gray has high contrast against white tiles. Light grays blend in more subtly.
  • Beige or Brown match earthy stone tiles and provide a natural, organic style.
  • Black contrasts beautifully against white or light-colored tiles for dramatic effect.
  • Bold Colors like navy blue, dark green, or maroon complement equally richly-hued tile.

Consider testing grout color samples directly on your tile and in the room’s lighting before final selection. The ideal grout complements the tile while enhancing the overall design aesthetic.

Which Grout to Use for Backsplash – FAQs

How do I choose grout for kitchen backsplash?

For kitchen backsplashes, epoxy or urethane grout provide the best stain, mold, and water resistance. Sanded grout is an affordable option if you seal it regularly. Choose white or neutral shades to hide stains and match most decors.

What is the most durable grout?

Epoxy grout stands as the most durable and stain-proof grout option. It resists moisture, grease, acids, and chemicals that can stain and degrade other grout over time. Urethane grout offers durable performance as well. Both epoxy and urethane are ideal for backsplashes with high exposure to water and potential stains.

Can I use sanded grout on small tiles?

Sanded grout contains fine aggregates that help fill wide grout joints, but may scratch smooth, polished, or natural stone surfaces. For tiles smaller than 4 inches with narrow grout lines, unsanded grout provides a smooth finish and prevents abrasion.

What color grout is best?

White and light gray grout are popular options that provide a clean, bright look. Dark gray and black grout highly contrast against white tiles. Earth tones like beige and brown complement stone surfaces well. Choose grout color based on the tile color and overall design aesthetic you wish to achieve.

How do I get a smooth grout finish?

Start with unsanded grout for narrow grout lines under 1/8 inch. Tool the grout carefully into joints, holding the float at a consistent angle. Avoid overworking the grout which can pull aggregate to the surface. Once applied, smooth the grout haze gently with barely damp sponges and minimal pressure. Allow proper curing time before polishing with a terrycloth.


Choosing the ideal grout involves considering your tile material, the backsplash location, desired aesthetics, and weighing the pros and cons of different grout types. For high-exposure kitchen backsplashes, epoxy and urethane grout deliver unparalleled durability and stain resistance. Sanded and unsanded grout offer versatile, affordable performance for most applications. Proper installation and sealing is key to maximize grout life and maintain the backsplash appearance. With the right grout selection and care, your backsplash can stay beautifully protected for years to come.
