how to cover hairline crack in sink?

[OsloGin]

I have a white porcelain sink in the bathroom which has a finger length hairline crack in it. Can anyone recommend a way to cover this even temporarily, it will be a good 6 months before we can afford to replace it. The crack looks dirty and I can't seem to lighten it.

Friendly warning, someone I know badly damaged their arm when a cracked sink suddenly gave way and cut them, they severed nerves and tendons and have never regained full use of their hand. Make it a priority to replace it, what if it broke if a child swung on it on someone leant on it (friend was trying to unblock plughole when his cracked sink broke)?

Sorry not to be able to post a quick fix.

The Plumb Centre has cheap sinks from about £50. I would not patch it. Or maybe the local tip has sinks? We just took a 30s style one to our local tip and they put it on one side because they knew someone would want it.

Thanks it is only a surface crack but I didn't know that sinks could be replaced quite so cheaply. Will have a look.

My brother thought that too OP, until he dropped a can of deodorant on it and half of the sink landed on his food and severed the tendons. Very painful.

As the others have said, it really is best to replace it. The crack will spread and the sink will not be secure. We experienced this. I no longer store anything with sharp edges in the cabinet above the sink.

We successfully repaired a double ceramic butlers sink in the kitchen. We had a professional quote for £300 so bought a £30 kit from Amazon. It's not perfect but much cheaper than having a new sink.

It is usual for home buildings insurance to include accidental damage to sanitary fixtures and fittings (i.e. your sink).
