How to Recolour Your Grout for a Complete Room Makeover

You feel like your room is too dark and closed in. You’ve tried everything to make your room feel brighter and bigger. Nothing has worked very well?

This is what happened to our customer Sarah from Brisbane. Sarah had tried changing the tapware, painting the walls, switching the lights to a warmer coloured bulb, but the room still felt dull and closed in.

When Sarah contacted GroutPro to get her shower restored, she mentioned the issues she had with her bathroom – that it was dark, dull and felt small. Our technician suggested something she hadn’t considered yet… colouring her grout lines.

Instead of sticking with the dark grey grout that came with the house, Sarah chose a soft white tone to match the walls and tiles. The technician explained it would create a seamless, more open feel — almost like visually “extending” the space.

The change was instant. The tiles looked brighter, the room reflected more light and the space felt much bigger, all thanks to grout!

Your grout might seem like a small detail, but it has a massive influence on how a room looks and feels. Whether your tiles are still in great condition or just need a lift, changing your grout colour can completely transform your space — from dull and dated to bright and modern — without the cost of a full renovation.

Here’s how you can refresh, recolour, or replace your grout, and how GroutPro can help every step of the way.

Option 1: Professional Tile and Grout Cleaning

Best for:

Grout that’s discoloured or patchy, but still in solid condition.

When to Choose It:

If your tiles and grout look darker than they used to, it’s often due to years of absorbed dirt, soap scum, and residue. A professional clean can lift those stains and restore your grout’s original colour — giving your space a quick and affordable facelift.

Why It Works:

Grout and tiles are porous and hold onto grime that ordinary household cleaners can’t remove. GroutPro’s professional-grade cleaning equipment and specialist solutions extract deep-seated dirt, restoring the true colour and finish of your tiled surfaces.

What You’ll Get:

A brighter, cleaner, fresher appearance
A low-cost, short-term way to refresh your tiles
Perfect for homes being sold, rented, or just needing a quick lift

✅ Result: A lighter, more open-looking space that feels instantly refreshed.

Option 2: ColourSeal

Best for:

Homeowners wanting a new grout colour and long-term protection without regrouting

When to Choose It:

If your grout is still intact but looks dated or doesn’t suit your current décor, ColourSeal is the ideal solution. It’s a professional-grade coating that recolours and seals grout in one step.

Why It Works:

ColourSeal bonds to the surface of existing grout, creating a uniform colour and a barrier that repels stains, dirt, and moisture. It not only transforms the look of your tiled area but also makes cleaning easier for years to come.

What You’ll Get:

Over 80 colour options, from bright whites to deep charcoals
A waterproof, stain-resistant, and mould-resistant finish
Easier ongoing cleaning and maintenance
A grout colour that complements your tiles and décor perfectly

✅ Result: A completely transformed tiled area that looks brand new — and stays that way for years.

Option 3: Re-Grouting

Best for:

Grout that’s cracked, missing, or deteriorating.

When to Choose It:

If your grout is falling out, discoloured beyond cleaning, or allowing moisture through, recolouring won’t fix it. Regrouting replaces your old grout completely, restoring both the look and the integrity of your tiled area.

Why It Works:

GroutPro’s regrouting service removes all existing grout and applies new, high-performance grout — restoring watertight protection and a clean, uniform finish. In wet areas like showers and balconies, epoxy grout is the top choice for long-lasting waterproofing and durability.
