Grout is the material used to fill the gaps between tiles. It helps hold tiles in place, prevents water from seeping between them, and supports structural stability. Grout also affects how your tiling looks overall. The colour of the grout can highlight tiles, blend them together, or create a balanced finish. Choosing the right grout colour makes all the difference to the final look of your bathroom, kitchen, floor, or feature wall tiling project.

Matching, Contrasting, or Neutral Grout: The Three Main Options
When choosing a grout colour, first decide the effect you want.
1. Match the Grout to the Tile
Pick a grout colour that closely matches your tile colour. This creates a calm, seamless, and uniform look, suitable for minimalist or modern designs. The advantage here is that the focus stays on the tiles themselves. We recommend this matching grout for marble, stone-look tiles, or subtle tile patterns.
2. Contrast the Grout with the Tile
Choose a grout that is noticeably lighter or darker than the tile. This highlights the shape, layout, and pattern of each tile, which can be very effective if the tiles have an interesting shape. We recommend this for subway, herringbone, or tiles with slightly more complex geometric shapes. It works well for feature walls and patterned layouts.
3. Neutral Grout Colours
This uses grout colours like light grey, beige, sand, or taupe. It offers a balanced look, and is easier to maintain than white grout. Neutral colours work well with almost all types of tiles, so it’s a good, safe option when you are unsure what might work.
Other Key Factors to Consider
Location and traffic levels is something to consider. High-traffic areas like floors work well with darker or neutral grout colours, which are better at hiding dirt and stains. Light grout is better suited for low-traffic areas such as walls or kitchen splashbacks.
Tile Undertone
Tiles can have warm undertones (beige, cream) or cool undertones (grey, blue). Select a grout colour that complements the undertone rather than clashes with it.
Tile Pattern or Texture
A highly patterned tile will benefit from matching or neutral grout to avoid visual clutter. If there is too much detail the room will feel crowded, and the pattern of the tiles will be lost in all this detail. So, let the grout stay in the background, and let the pattern on the tiles shine through.
If you have a plain type of tile, then contrasting grout can add character. Consider how white tiles might look with vivid orange or blue grout. Else, you might like white grout on white tiles for an open, clean look. Or black marble pattern tiles with white grout for an old Roman theme.
Testing Before Deciding
Always test grout with a sample tile. Apply a small amount once the tile is laid or rub dry grout powder into gaps to see how the colours work together.
Can You Replace Grout Without Replacing Tiles?
Yes, the process of regrouting will remove the old grout while keeping the tiles intact. This is usually done to fix cracked or stained grout, often just in the areas that have suffered damage. It can be used to replace all of the grout, perhaps to change the colour to give the tiles a different effect. However:
- Regrouting is a slow and time-consuming process.
- Considerable care is needed to avoid damaging the tiles.
- For large areas, it is best done by a professional.
Waterproofing and Sealing Grout
Grout is generally porous, especially cement-based grout. This means it can absorb water, soap, and dirt. This leads to staining and mould. Over time it can also lead to cracking. So, it is important to seal/waterproof grout for long-term protection. Sealing is vital in wet areas like showers, bathrooms, and kitchen splashbacks.
Options for Waterproofing:
Grout Sealers
These are applied after the grout has cured. Both water-based and solvent-based sealers are available. They create a barrier to moisture and stains. Most cement grout needs sealing every 1–2 years.
Epoxy Grout
This is a naturally waterproof, non-porous type of grout. It does not need sealing and is quite resistant to stains, mould, and chemicals. The downside is that it is more expensive and requires skilled installation.
Latex-Modified Grout
Cement grout mixed with latex to improve water resistance.
Maintenance and Cleaning
No grout or tiles are completely maintenance-free. Light-coloured grout may show stains faster, while dark grout can develop white salt deposits (efflorescence) over time.
Basic cleaning tips:
- Use warm soapy water and a soft brush for routine cleaning.
- Avoid harsh or acidic cleaners unless recommended for grout.
- Baking soda and water paste can help clean stains naturally.
- For severe discolouration, grout pens or regrouting can restore appearance.
Final Tips for Choosing Grout Colour
Choosing the right tiles comes first, but we must always remember that that it is the combination of tiles and grout that creates the final look.
- Consider which look you prefer, seamless, bold, or balanced.
- Remember that where the tiles are used and how much cleaning you’re willing to do. You might prefer an easy to clean option.
- While many colour combinations exist, always use warm tiles with warm-toned grout and cool tiles with cool-toned grout.
- Test grout colours before committing to the whole project.
- Use darker or neutral grout in busy areas to reduce visible stains.
- Seal cement grout to protect it and extend its lifespan.
Final Thoughts
Don’t make the mistake of thinking that the grout colour is a small detail. Different colour combinations of grout and tiles will make a huge difference to the appearance of the project. Use this to you advantage. Find tile/grout colour combination that give attractive, stylish results, and produce tilework that is effective and unique.
