OK. I fitted a new sink and it all went well apart from the fact that the existing hole in the worktop is slightly too big for the new sink.
So, even after positioning it as well as I can, there is still about
1mm gap at one end.
Any suggestions on the best way to fill this gap? I was thinking of flexible silicone but then I'd have to go alll the way around the sink.
Another option is wood filler but trouble here is the worktop is a dark, spotty pattern so it might look a bit odd.
