Best Overall Grout for Shower: Custom SandStone PMG180QT

Custom, Sandstone PMG180QT 1-Quart Simple Premium...

The Custom SandStone PMG180QT grout comes pre-mixed which makes it easy to use. This also means it will not create a mess when you are repairing your shower tiles. This unsanded grout offers protection from contracting and breaking as it has a crack-resistant, non-shrink formula resistant to water.

It’s also important to mention that this tile grout is not meant for prolonged exposure. However, you can still use it in your shower. Another great thing about the Custom SandStone grout is that it’s resistant to common household stains. So, you don’t have to worry about its color fading.

Additionally, you can apply this product on countertops, bathtubs and floors. It can keep those delicate surfaces scratch-free. This makes it perfect for surfaces such as glass, porcelain and natural stone.

Applying this cement-based grout is also easy and you can use it to cover joints that range from 1/16 inches to ½ inches. Moreover, it is ideal for restoring sanded grout you may have on your shower. The PMG180QT grout is also perfect if you like to keep your workspace clean, since you can clean it effortlessly using a sponge.

The only major issue with this product is that you shouldn’t use it when the temperature is below 50 degrees Fahrenheit. You should also seal this grout for better protection and avoid cleaning it with high-water pressure.

Best Grout Shower for the Money: Custom PMG122QT

Custom PMG122QT 1-Quart Simple Premium Grout,...

The Custom PMG122QT is another great pre-mix grout that makes life easier as it doesn’t require mixing. It offers excellent durability, can resist abrasion and it consists of high-quality cement. It also firmly secures stone, porcelain and ceramic tiles. 

If you have heated tiles at home, this grout is an excellent choice as it is heat-resistant. Additionally, it’s grime and water-resistant. So, you won’t have to use a sealer to protect the installed cement. We also like this product because it is environment-friendly. 

It doesn’t produce dangerous volatile organic compounds. This grout is also available in multiple colors to allow you to create a contrasting effect or blend your tiles. The outcome will be a uniform and smooth color throughout. 

This grout for shower can also withstand acidic and alkaline products. This means you can use any cleaning agents you may have including those with chemical compounds. Of course, you can also use it to seal joints and restore broken cement-based grout.

The only issue with this grout is that its container is small and may not hold enough grout for covering large areas. This means you may have to look for another alternative if you are working on large projects.

Like the Custom SandStone, it won’t crack or shrink even under high water pressure. Your shower won’t also accumulate dirt as it is resistant to stains. If you are looking for shower grout that can cover several tiles and is waterproof, consider buying this product.

Best Cheap Grout for Shower: Red Devil 0425

The Red Devil 0425 shower grout is a good alternative if you don’t like spreading cement all over your newly installed tiles. This small tube has acrylic-based grout that is easy to use. Moreover, this unsanded paste doesn’t scratch delicate tiles and other materials. 

You can also use this shower grout on masonry and wood surfaces, as well as wallboards. One good thing about the paste in this tube is its user-friendly consistency, which makes it ideal for DIY beginners. Just cut the end, and then start applying it over the lines.

After 10 minutes, you can remove the excess paste using a wet sponge. You can then apply a sealer after 2 days to protect the grout. You can also apply this shower grout after installing your new tiles or to refill your old grout. Just remove 1/16 inches of the old grout and then lay a new coat.

The Red Devil shower grout is VOC (volatile organic compound) compliant. VOCs can cause dangerous fumes when exposed to the sun. To keep you safe, this manufacturer has adhered to the required VOC limits.

Bear in mind that one tube may not be enough if you intend to cover a large surface area. You will need to have a larger tube size if you want to apply it all over your shower. This shower grout also produces an unpleasant smell. When applying it, open your windows to ensure proper ventilation.

What We Like 

  • Perfect for people that don’t like spreading cement 
  • Suitable after installing new tiles 
  • Ideal for refilling old grout
  • Does not scratch delicate tiles

This unsanded shower grout boasts of an innovative EZ Squeeze tube that enables the paste to come out smoothly. This allows for a smooth flow of the paste during application while ensuring each section gets enough grout.

Additionally, different formulas are available for bath and kitchen caulk, door and window caulk, tile adhesive, as well as wall seam repair. The Red Devil paste is perfect for covering damaged grout in mosaic and ceramic tiles on shower walls.

You can also use this water-resistant paste to remove stains and repair tile joints. You can also use it to repair broken, cracked and loose tile grout installed on your showers’ wall. Moreover, it’s ideal for all types of shower tiles as it has a white color.

When it comes to drying up, this paste only takes 30 minutes, leaving a stunning look on your tiles. Its tube-squeeze design also makes working fun and looks attractive. Additionally, its mild ammonia and acrylic will leave your tiles smelling nice.

The only major drawback of this product is its small 5 ounces capacity. This makes the tube suitable for basic grouting as it can only withhold a small amount. Also, getting the paste out of the tube requires a lot of effort.

Interestingly, this product doesn’t leak on lower tiles due to its snag-free texture. This is very convenient, especially when applying the grout on vertical surfaces. We also like the built-in sealer. This means you won’t have to do anything else once you have installed the grout.

Another great this about this shower grout is that it’s designed to last. It has an antimicrobial protective layer that keeps mildew and mold at bay. The color also remains stable as it doesn’t fade or turn yellow. 

Additionally, the smooth polymer formula makes this grout stain and water-resistant. The Red Devil mixture is also versatile since it’s compatible with stone, ceramic, porcelain and metal.

Grout for Shower Features and Considerations

Grouts protect tiles from mildew and moisture while also providing smooth finishing. However, grouts are available in various colors and types, which can make choosing the right product difficult. These are the factors you should consider when looking for the best grout for shower:

Wet shower tiles fixed with grout solution

Type of Grout

Grout has different additives that determine its applications. Some common grout types include:

Cement Grouts 

This type of grout is perfect for use in bathrooms as it is easy to prepare and use. It also provides high-quality results and is affordable. However, you will have to apply a sealer to prevent water and moisture from getting in since cement grouts tend to have a porous surface.

Cement grouts also require 48 to 72 hours drying time before you can add the sealer layer. 

Epoxy Grouts

These grouts are a mixture of powder filler and resin that can be difficult to work with. Also, applying them is tricky because they dry quickly, usually within 30 minutes. However, epoxy grouts are resistant to water, grease and stains.

Some even prevent mildew and mold from forming, making them a common choice in showers. However, you should budget for them because they are costly.

Unsanded vs. Sanded Grout

Unsanded grout is safe for use on delicate materials like marble or glass tiles because it does not contain abrasive sand.

Since this paste has a sticky consistency, you can apply it effortlessly on vertical surfaces like a shower wall. 

On the other hand, sanded grouts are bulkier and thicker than their unsanded grouts counterparts since they are filled with sand. You can apply sanded grouts on tougher surfaces because they are more durable.

Other Crucial Factors

Apart from the type of grout, here are other essential features you should check:

  • Mold-Resistant: Mold and mildew can be dangerous to your health. Due to this, you should pick a mold-resistant shower grout to prevent the fungi from developing between the tiles.
  • Waterproof: This feature will prevent water from penetrating the grout. In turn, this will prevent mold from growing.
  • Non-Toxic: When shopping, avoid shower grouts that produce dangerous fumes when inhaled.

Wrap Up

Grout needs regular cleaning as it tends to accumulate soap scum, grime and stains over time. Selecting the right cleaning product is the best thing to do as it will keep your shower grout in good shape and also prolong its lifespan. 

Now that you know the type of grout that suits your needs, go ahead and choose the perfect product to help you secure your tiles after installing them.
