Sanded vs. Unsanded Grout: Which Should You Use?

Choosing grout may seem like a small detail, but the wrong product can affect the appearance and durability of a tile installation. The correct grout depends on the joint width, tile surface, location, and manufacturer’s instructions.

Sanded Grout

Traditional sanded grout contains fine aggregate that helps reduce shrinkage in wider joints. It is commonly used for many floor tile installations, wider grout joints, high-traffic areas, and some exterior applications.

Because the aggregate can scratch certain polished, glass, or delicate surfaces, a small test area may be necessary before installation.

Unsanded Grout

Traditional unsanded grout has a smoother texture and is commonly used for narrow grout joints, wall tile, polished or delicate tile that could be scratched, and some vertical applications where a smoother finish is preferred.

Unsanded grout is not automatically the correct choice for every shower wall or narrow joint. Product requirements vary.

What About Modern High-Performance Grout?

Many newer cement-based grouts are formulated for a broad range of joint widths and may not fit neatly into the traditional sanded-versus-unsanded categories.

There are also epoxy and ready-to-use grouts with different installation and maintenance characteristics. The installer should confirm approved joint width, tile compatibility, wet-area suitability, stain resistance, and required sealing and maintenance.

Which Grout Is Best for a Bathroom?

The answer depends on the tile and the location. Bathroom floors need a grout that can handle foot traffic, cleaning, and moisture exposure. Shower walls and floors require a product approved for wet areas.

Most importantly, grout does not waterproof a shower. A complete waterproofing system must be installed behind or directly beneath the tile assembly.

For professional bathroom remodeling in Jacksonville, proper grout selection is part of every tile installation.

Final Takeaway

The best grout is the one that matches the joint width, tile surface, installation area, and manufacturer’s specifications.
