Sanded vs Non-Sanded Grout for Bathtub & Shower Floors: Choosing the Right Finish

When designing a bathroom with a bathtub or shower, flooring grout plays a crucial role in both aesthetics and functionality. Choosing between sanded and non-sanded grout can significantly impact durability, slip resistance, and long-term maintenance—especially in wet environments. Understanding these differences helps homeowners make informed decisions for safer, stylish, and lasting bathroom spaces.

Understanding Sanded vs Non-Sanded Grout

Sanded grout contains fine silica sand that enhances strength and helps fill larger gaps between tiles, making it ideal for showers and bathtubs prone to water exposure. Its texture improves resistance to cracking and shifting. In contrast, non-sanded grout lacks sand, offering a smoother finish perfect for smaller gaps and tile types in low-moisture areas. While non-sanded grout is easier to apply and clean, it offers less structural support compared to its sanded counterpart, influencing its suitability for high-slip zones like bathrooms.

Sanded Grout: Strength and Durability for High-Moisture Areas

Sanded grout excels in environments with consistent moisture and frequent water exposure, such as showers and bathtub floors. The sand particles increase tensile strength, reducing the risk of cracking under pressure or temperature changes. This makes sanded grout the preferred choice for areas subject to heavy use and water splashing. However, its coarser texture can collect soap scum and requires meticulous cleaning to prevent discoloration. Proper application with a quality sealer further enhances its longevity and resistance to mold and mildew.

Non-Sanded Grout: Smooth Finish and Ease of Use

Non-sanded grout delivers a sleek, seamless appearance ideal for minimalist or modern bathroom designs. With no sand to compromise coverage, it fits perfectly in tight tile joints and allows for finer grout lines. Though less durable under heavy moisture stress, non-sanded grout performs well in dry shower nooks or non-continuous tile patterns. Its smooth surface is easier to sanitize and less prone to trapping debris, making it a practical option for low-traffic spaces where aesthetics outweigh extreme durability needs.

Key Considerations for Choosing the Right Grout

Selecting between sanded and non-sanded grout depends on several factors: moisture level, tile type, design preferences, and maintenance commitment. For bathtubs and showers with frequent water exposure, sanded grout is recommended to prevent wear and slipping. Non-sanded grout suits drier or decorative areas where a smooth finish is desired. Always consider applying a long-term grout sealer to protect both types, especially in humid environments. Consulting a professional ensures optimal selection and installation for a safe, beautiful bathroom floor.

Choosing between sanded and non-sanded grout for your bathtub or shower involves balancing durability, appearance, and maintenance. Sanded grout offers superior strength and slip resistance for high-moisture zones, while non-sanded grout delivers a clean, smooth look ideal for design-focused spaces. By evaluating your bathroom’s unique needs and consulting expert advice, you can select the perfect grout that combines functionality with style—ensuring a lasting, safe, and inviting bathroom environment.

Which type of grout is best for marble floors, or for tiling walls? Learn the differences between sanded and unsanded grout before your next DIY.

Sanded grout is less expensive than unsanded grout since sand is a cheaper filler than the polymers in unsanded grout. Due to its porous nature, sanded grout, unless modified, must be sealed to prevent water from infiltrating the back of the tile and ruining the substrate. Seal with a pH-neutral, water-based, penetrating sealer.

Grout is essential for preventing water damage in a shower, but choosing between sanded and unsanded grout can be confusing. The tile that you use, its grout line width, and the type of grout you choose can have a significant impact on the long. It's also referred to as non-sanded grout.

Sanded grout is thicker and more durable than unsanded grout because it holds up against shrinkage. Sand particles hold the grout together and become suspended as the grout sets, resulting in less shrinkage. The sand is locked as the grout cures and doesn't move, even after drying.
