repairsink
Last night I managed to drop something onto my bathroom sink, which now has a large crack in it and is obviously leaking when I turn the tap on. I know I will have to replace the sink, but I cant really afford that at the minute.
Is there something I can maybe put into the sink that will hook over the sides so the water drains into that and down the plughole instead of directly in the sink basin?
You want a basin wrench. It cams sort of like a pipe wrench, so it should be able to grip almost anything. Insert the handle from the other side to cam the other direction.
The two top holes in the corners are there because the sink is hollow. They are from the making of the sink. You will not use those holes. Every wall mounted sink that I have installed uses a bracket that is mounted on the wall first into at least one stud, then the sink drops down onto the bracket. The two lower holes then would probably line up to two holes on the bracket so the sink cannot be accidentally moved or bumped off the bracket.
If you do not have the bracket, you may have to fabricate one (I would use wood). It should not get wet back there if you caulk along the top of the sink after installation, so the wood should not fall apart over time.

You can probably fill the crack with epoxy to stop the leak. It might not look great but it will do the job.
Make sure the area is clean and dry, and that you follow the directions on the packaging. If there is any chipping make sure to brush away any loose debris so that the epoxy will bond correctly.
As far as what type of epoxy to use, Home Depot carries a Marine Epoxy which they describe as:
This sounds like it would work well for your application.
