Don't Forget Grout Colour — It Changes How Your Tile Looks

It's easy to spend hours choosing a tile and then treat grout as an afterthought — but grout colour has a real, visible effect on the finished result. The same tile can look completely different depending on whether the grout blends in or stands out.

Contrast vs. match — the two basic approaches

Matching grout

Choosing a grout colour close to the tile itself minimizes the visible grid of lines between tiles, making the surface read as one continuous expanse. This tends to make a space feel larger and more seamless — a common choice for smaller bathrooms or anywhere you want the tile to feel like a backdrop rather than a feature.

Contrasting grout

A grout colour that stands out from the tile emphasizes the pattern and layout — every joint becomes visible, which can look intentional and graphic (think classic white subway tile with dark grout) or busy and distracting, depending on the tile shape and how much contrast you choose. This works well when the tile's shape or layout is part of the design you actually want to showcase.

Practical things that affect the decision

• Maintenance — light-coloured grout shows dirt, grease, and mildew more visibly over time, especially in kitchens and shower floors. Darker grout hides staining better, which matters more in high-traffic or high-moisture areas.
• Sanded vs. unsanded — grout lines wider than about 1/8 inch typically need sanded grout for strength; narrower joints use unsanded. This is a functional decision your contractor will usually make, but it can slightly affect which colours are available in your chosen brand.
• Sealing — grout is porous and will absorb stains and change colour slightly over time if left unsealed, especially lighter shades. A proper sealant (reapplied every year or two depending on the area) keeps the colour closer to what you originally chose.
• Small tile vs. large format — smaller tiles (like mosaics) have proportionally more grout line, so grout colour has a bigger visual impact. Large-format tile has minimal grout showing, so the choice matters less dramatically.

A simple way to decide

If you want the tile itself to be the visual focus and the space to feel calm and expansive, lean toward a matching or close-to-matching grout. If the tile's shape, pattern, or layout is something you actually want to highlight — herringbone, subway, hexagon — a contrasting grout will show that off rather than hide it. Neither is objectively better; it depends on whether you want the grid of joints to disappear or to become part of the design.
