01The visible list
On a bathroom that is sound behind the surfaces, these produce most of the change a buyer notices.
- Re-caulking tubs, showers and every wet junction
- Replacing stained or failed grout
- A new vanity and countertop, or refinishing a sound one
- A modern mirror, and lighting that is not a single dim fixture
- New taps and shower fittings
- Flooring, where it is dated or damaged
- Replacing a chipped or stained toilet
- Storage — the single most common complaint about small bathrooms
02Find the water before you cover it
The most expensive bathroom mistake is cosmetic work over an active moisture problem. Soft flooring near the tub, a fan that vents into an attic, a stain on the ceiling below, tile that sounds hollow — each is a reason to open something up before finishing anything. Tiling over a leak buys about a year and creates a far larger bill.
This is also an inspection issue. A buyer's inspector will find what you covered, and finding it at that stage costs you more than fixing it would have.
03Ventilation is not optional
A bathroom fan that does not move air, or vents into the roof space rather than outside, produces the mould and the ruined finishes that show up in the next inspection. It is a genuinely cheap item to correct and one of the few improvements that pays for itself by preventing a problem rather than creating an impression.
04Avoid the highly personal
Bold tile, unusual fixtures and strongly styled finishes are exactly the things the next owner is most likely to remove. In a bathroom you are preparing for sale, the goal is a room nobody objects to rather than one somebody loves.
