How to choose the right grout colour

The “best” grout colour depends on the look you want and the reality of how the space will be used. Use the guide below to pick a shade that looks great and stays looking clean.

Option A: Match the tile (seamless & calm)

Best for: large-format tiles, stone looks, minimalist bathrooms.
Effect: makes surfaces feel larger; grout lines “disappear”.
Pro tip: choose a shade 1–2 tones lighter/darker than the tile to avoid a “grid” effect.

Option B: Contrast the tile (definition & pattern)

Best for: metro/subway layouts, herringbone, mosaics and feature walls.
Effect: highlights shape and pattern; gives a designer finish.
Pro tip: use darker grout for busy areas (kitchens/floors) to hide day-to-day marks.

Practical checks (before you commit)

Tile finish

Matt tiles can handle stronger contrast; polished tiles often look best with softer, tone-on-tone grout.

Room usage

Kitchens, hallways and showers benefit from mid-to-dark shades that disguise everyday marks.

Cleaning & maintenance

Very light grouts look crisp but show staining sooner. Choose smarter colours for family homes and rentals.

Test board

Make a small sample board (tile + grout) and check it in morning/day/evening lighting.

Which Ardex grout should you use?

Colour is only half the decision — grout type impacts stain resistance, cleanability, setting time and suitability for wet areas. Here’s a simple way to choose.

Pro tips for consistent grout colour (and a cleaner finish)

Avoid patchiness

Measure water accurately: small changes can affect shade and strength.
Mix consistently: same mixing time and resting time between batches.
Work to a rhythm: grout a section, tool it, then clean at the right time.
Temperature matters: hot rooms can dry grout too fast; cold rooms can slow curing.

Choose a smarter colour for real life

High-traffic floors: mid greys, taupes and darker tones hide everyday marks.
Showers & wet rooms: consider epoxy in heavy-use or commercial settings.
White grout: looks crisp, but needs more frequent cleaning in splash zones.
Stone installs: use specialist grout options designed for sensitive materials.

Maintenance basics

Keep grout looking fresh by wiping down wet areas after use, improving ventilation, and using pH-neutral cleaners. Avoid harsh acids on cement-based grout and on natural stone.

FAQs: Ardex grout colours & selection

Will the grout colour look the same as the chart? ⌄

Charts are a guide. Lighting, tile texture and joint width can change how colour is perceived. Shortlist 2–3 shades and test them next to your tile in the actual room.

Should I match grout to tile or go contrasting? ⌄

Matching gives a seamless, calm look (great for large formats). Contrasting highlights the layout and pattern (great for metro, herringbone and mosaics). Your joint width and room usage should guide the final choice.

Which grout is best for showers and wet rooms? ⌄

For heavy-use wet areas, an epoxy grout is often the best choice due to durability and stain resistance. For standard domestic installs, a quality flexible grout can also be suitable when installed correctly.

I’m using marble or sensitive stone — what should I choose? ⌄

Use a grout designed specifically for moisture-sensitive natural stone to reduce the risk of water staining around tile edges.
