How to Choose The Right Grout for Your Bathroom

When installing bathroom tiles, it is essential to choose the right grout filler for it. It would serve as the “joints” of the tiles. Thus, it makes the tiles more intact. Moreover, it can help improve the overall appearance of your bathroom tiles. However, there are many types of grout in the market, so it is not easy to choose the right one for your bathroom. 

If you are not sure what type of grout you should buy, then do not worry! In this article, we have outlined what is one of the most ideal grout fillers for bathrooms in Singapore. Moreover, we will tackle the colour that you should choose for your bathroom tiles. You will learn how to mix and match the colour of your tiles and your grout filler.

Unsanded vs Sanded Grout

Once you start shopping for grout fillers, you would come across these two different types: sanded and unsanded. It is essential to know the distinct differences between these two to ensure the success of your bathroom tile project. 

Unsanded Grout

  • Between the two, unsanded grout is easier to work with if it is going to be used for the shower walls. It is because the filler material is sticky, so it will not easily drip on vertical surfaces. If you are wondering why it is sticky, then it is because it doesn’t have a “silica aggregate filler”.

  • Since it does not have a silica aggregate filler, it is suitable for bathroom tiles with non-scratch resistant surfaces. Examples of these tiles are glass, marble, ceramic, and natural stones. 

  • It is also ideal for bathroom tiles with thin, narrow joints in between. Most often, the joints should be at least ⅛ inches to 1/16 inches at most. 

  • If you check out some grout contractors in Singapore, then you would discover that unsanded grout is more expensive than the sanded ones. Even though this is the case, quality is assured. 

Sanded Grout

  • It is an affordable choice among homeowners because it is made of cheap fillers! Thus, if you are worried about your budget, then you should choose sanded grout. Not only is it cheap, but it could also hold your tiles well. 

  • Even though it is an effective bond material for your tiles, it should still be sealed after you install your bathroom tiles. Doing this would help prevent the water from seeping through the tiles. The seal will act as a protective barrier for the tiles’ substrate. 


  • It comes with a wide range of colours, so you can easily find a colour that matches your bathroom tiles! 


  • Sanded grout is best for tile joints that have a gap of ⅛-inch or ½-inch. 


  • It doesn’t shrink or crack easily because of the presence of the silica aggregate filler. 


Other Grout Options: Epoxy and Urethane


Aside from sanded and unsanded grout, there are two other types: epoxy and urethane. Get to know what are the pros and cons of these two below. 


Epoxy Grout 


You can get the best of both worlds with epoxy grout! It has many advantages such as having high durability. Because of this, it is commonly used in commercial buildings as well. Even though you are going to use cleaners with harsh chemicals, its colour would not fade easily. A good example of durable epoxy grout is the Davco! What’s more, it doesn’t need a sealer! You do not have to worry about stains, as well as water seepage. 


Moreover, it doesn’t have a tile joint size requirement. Whether your bathroom tiles are wide or narrow, you can use epoxy grout. It is a versatile type of grout which you can use to almost all types of tiles


There is just a bit of handicap when using epoxy grout. You have to hire a professional to install it because it dries up quickly. It would be difficult to fix it if it is already dry as you have to start over with the installation again. So, it would be better if you have a renovation contractor that could help you out. 




Polyurethane is the newest addition to the grout types that are available in the market. It is like an upgraded version of all the grout fillers. It is stain-resistant and durable like epoxy grout, and it does not need to be sealed. However, since it is still new in the market, the colours available are limited. 


How to Choose the Right Grout Colour


Another aspect to consider when choosing a grout filler for bathrooms or showers is the colour. There is just one important thing to remember when choosing a grout colour— the contrast. Using a grout colour that is in contrast with the colour of the tiles could add a dramatic flair in your bathroom. 


To use the contrasting grout colour concept effectively, you can pair up a with white tiles with a dark-coloured grout. Doing this will make the tiles stand out more. 


You could also take into account the grout size. If you want the grout to appear almost invisible because you want to accentuate the tiles, then you should make the grout size smaller. Meanwhile, if you want the grout colour to stand out, then make the gaps wider.
