A full bathroom renovation can cost £3,000–£15,000 or more — a significant investment that many homeowners can’t justify, particularly if the bathroom is structurally sound and the layout works. But you don’t have to choose between an expensive full renovation and living with a bathroom that’s seen better days. Professional surface repair can transform the appearance of a tired bathroom at a fraction of the cost.
The Repair vs Replace Decision
For each element of a bathroom, the question is: is the problem cosmetic or structural? Cosmetic problems — chips, stains, worn surfaces, wrong colour — can usually be repaired. Structural problems — leaking, cracked through structure, permanently stained beyond repair — need replacement.
The Bath: Repair or Replace?
Replace if: structural cracks, fibreglass delamination, or it’s simply the wrong size or shape for the space. Repair if: chips, stains, surface yellowing, colour you don’t like, minor chips or rough surface. Cost to repair vs replace: £150–£400 repair vs £600–£3,000+ replacement including fitting.
Tiles: Repair or Replace?
Replace if: tiles are structurally loose, there’s moisture behind them, or you want a completely different layout. Repair if: individual chips or cracks, stained grout, old-fashioned colour. Grout can be re-coloured. Tile chips can be repaired. Mouldy silicone can be replaced. Full retiling typically costs £800–£3,000 for a bathroom — individual tile chip repair costs a fraction of this per tile.
The Shower Tray: Repair or Replace?
Repair if: chips, surface marks, minor cracks. Replace if: leaking under the tray, severe cracking. Shower tray replacement involves significant disruption; repair is almost always worth trying first.
What Can’t Be Repaired?
Surface repair has limits. A bath that’s the wrong size can’t be made bigger. A layout that doesn’t work can’t be improved without structural changes. Very severely deteriorated surfaces — extensive crazing, widespread delamination — may be beyond economical repair. In these cases, we’ll tell you honestly before quoting.
