Is prism grout good for showers

When tiling a shower, choosing suitable grout is just as important as choosing the right tiles. Many different types of grout are available on the market, each with its unique characteristics and benefits. One type of grout that has gained popularity in recent years is prism grout. But is it a good choice for showers? In this blog post, we’ll explore the pros and cons of using prism grout in showers and provide some helpful tips for those considering it for their shower tiling projects.

What is Prism Grout?

Prism grout is a type of epoxy grout known for its durability, stain resistance, and water resistance. It is made up of a two-part system that consists of a resin and a hardener. When mixed, these two components create a strong and resilient grout resistant to cracking and chipping.

Benefits of Using Prism Grout in Showers:

There are several benefits to using prism grout in showers. One of the main advantages is its durability. Because it is made from epoxy, prism grout is much stronger than traditional cement-based grouts. It makes it resistant to damage from water and steam, making it an excellent choice for use in showers.

Another benefit of prism grout is its stain resistance. Unlike traditional grout, which can easily absorb dirt and grime, prism grout is resistant to staining. It makes it easier to maintain and keep clean, especially in showers where water and soap can leave behind residue.

Finally, prism grout is water resistant, essential in a shower environment. It can withstand high moisture and humidity levels without breaking down or deteriorating over time.

Drawbacks of Using Prism Grout in Showers:

While there are many benefits to using prism grout in showers, there are also a few drawbacks to consider. One of the main drawbacks is the cost. Prism grout is generally more expensive than traditional grout, so it may not be the best choice for those on a tight budget.

Another drawback is the installation process. Prism grout requires a more precise and detailed installation process than traditional grouts, and a professional is generally recommended to install it. It can add to the overall cost of the project.

Finally, traditional grout is more flexible than prism grout, which means it may be more prone to cracking in shower areas with movement or expansion.


Overall, prism grout is a good choice for showers due to its durability, stain resistance, and water resistance. While it may be more expensive and require a more precise installation process, the benefits of using it in a shower environment outweigh the drawbacks. Considering using prism grout in your shower, it is important to weigh the pros and cons carefully and consult a professional to ensure a successful installation.


Is prism grout better than traditional grout?

Prism grout has several advantages over traditional grout, including greater durability, stain resistance, and water resistance. However, it is generally more expensive and requires a more precise installation process, so some may have better choices.

Can I install a prism grout myself?

While it is possible to install prism grout yourself, it is generally recommended that it be installed by a professional due to the precise and detailed process required.

Is prism grout resistant to mould and mildew?

Yes, prism grout is resistant to mould and mildew. Its water-resistant properties help prevent these harmful fungi’s growth, making it a good choice for use in damp environments like showers. However, it is still important to regularly clean and maintain the shower to prevent the buildup of soap and grime, which can contribute to the growth of mould and mildew.

Can prism grout be used on all types of tiles?

Prism grout can be used on most tiles, including ceramic, porcelain, and natural stone. However, it is not recommended for use on certain types of tiles, such as marble or granite, as the high pH levels of the grout may cause discolouration or damage to the tiles. It is always important to consult with a professional or the tiles manufacturer to ensure that prism grout is suitable for use with your specific tiles.

How do I clean and maintain prism grout?

To clean and maintain prism grout, it is important to use a mild, pH-neutral cleaner and avoid abrasive or acidic cleaners. It is also important to regularly seal the grout to protect it from stains and keep it looking fresh. Sealing should be done every 1-2 years or more frequently in high-moisture environments like showers.
