When Should You Regrout Your Bathroom Tiles?
Cracked, discoloured or mouldy grout is not just unsightly — it can allow water to penetrate behind tiles and cause serious damage. Here is when to regrout and when to retile.
Grout is one of the most overlooked elements of a bathroom, yet it plays a critical role in keeping water out of the wall and floor structure. Knowing when to regrout — and when the tiles themselves need replacing — can save you significant money.
You should consider regrouting when: the grout is visibly cracked or crumbling, there are black mould stains that cannot be removed with cleaning products, or the grout has shrunk away from the tiles leaving visible gaps.
Regrouting involves removing the old grout with a grout rake or oscillating tool, cleaning the joints thoroughly, and applying fresh grout. It is a time-consuming job but significantly cheaper than retiling.
If the tiles themselves are cracked, hollow-sounding (indicating the adhesive has failed) or the waterproofing behind them has been compromised, regrouting alone will not solve the problem. In these cases, the tiles need to come off and the wall needs to be properly prepared and retanked before new tiles are fixed.
