Cracked, loose or missing grout can make bathroom tiles look tired and may allow water to reach the areas behind them.

If you've noticed damaged grout around your shower, bath or bathroom walls, it's worth dealing with it before the problem gets worse.

Why Does Bathroom Grout Crack?

Grout can deteriorate over time for several reasons, including:

• Movement in the tiles or underlying surface

• Ageing and general wear

• Poor installation or unsuitable grout

• Regular exposure to moisture

If grout keeps cracking in the same place, check for movement or other underlying problems before repairing it.

Can You Repair Cracked Grout Without Replacing All of It?

Yes. If the damage is limited to a small area and the surrounding tiles and grout are sound, you may only need to repair the affected joints.

However, widespread cracking, loose tiles or recurring water damage may indicate a bigger issue that needs attention.

How to Repair Damaged Bathroom Grout

1. Remove the damaged grout

Carefully remove loose or cracked grout using a suitable grout removal tool. Avoid damaging the surrounding tiles.

2. Clean the joints

Remove dust, debris and remaining loose material. Make sure the joints are prepared according to the replacement grout manufacturer's instructions.

3. Apply new grout

Choose a grout suitable for your tile type, joint width and bathroom application. Work it into the prepared joints using a grout float.

4. Clean the tiles

Remove excess grout using the method and timing recommended by the manufacturer.

5. Allow the grout to cure

Follow the product instructions before exposing the repaired area to water. Setting and curing times vary between products.

Should You Use Grout or Silicone Around a Bath?

This is an important difference.

Grout is generally used between tiles, while sanitary silicone is commonly used at movement joints and where tiled surfaces meet baths, shower trays or other fixtures.

These areas can experience movement, so rigid grout may crack if used where a flexible sealant is required.

Keep Your Bathroom Tiles in Good Condition

Regularly checking grout and silicone around baths and showers can help you spot damage early.

Choose the right repair product, follow the manufacturer's instructions and investigate any recurring cracks or moisture problems.
