Popular Shower Grout FAQs

What is the best grout to use in a shower?

We have found that the best grout to use in a shower is the UniBond Anti-Mould Waterproof Grout Sealant. This is because it is waterproof, has anti-mould properties, dries quickly, and is durable. These are all very important features that a good shower grout should have.

Is epoxy grout better than regular grout?

No, not necessarily. Epoxy grout is more durable than regular grout but the easy maintenance of grouted tiles should also be considered when making comparisons between epoxy and non-epoxy products. Conventional grouts are less expensive as well and, with proper care, perform just as well as epoxy for many applications.

Is grout waterproof in showers?

Yes, grout in the shower is usually waterproof. However, it can get damaged if enough water has been absorbed into the surface of the grout or if there is excessive moisture on the surface that compromises its structural integrity. Over time, salt deposits from hard water and mineral deposits will also stain your grout making it look dull and unattractive, requiring light maintenance now and then to keep it looking fresh and clean. If you are buying a grout though be sure to check if it is waterproof. 

How do you waterproof shower grout?

In order to waterproof shower grout, you will need to buy a grout sealer product. Before you waterproof your shower grout, you will need to clean, wipe and dry your existing shower grout to ensure the waterproofer can work effectively. Once you have done that, just follow the instructions on your chosen product. Typically you have to apply the waterproofer and leave it to dry for a specified period of time.

Is epoxy grout worth the money?

Epoxy grout is definitely worth the money. Unlike some regular shower grouts, epoxy grout won’t shrink, crack, or yellow/discolour, making it the perfect solution for application in wet areas, such as a shower or bathroom, for example. In addition, it is also resistant to harsh chemicals you’d find in most cleaning products.

Can I use caulk instead of grout in shower?

Caulk is a waterproof sealant or filler, typically used in building work, DIY and repairs. It is not a good idea to use caulk instead of grout in a shower because caulk can dry or shrink over time. This is why it is best to choose grout for your shower.

Do you need special grout for showers?

You don’t need a special grout for showers. Ultimately, as long as it meets your requirements it should be more than suitable. For me, I’d go for a shower grout that is inexpensive, has good reviews, waterproof and easy to apply.
