Sink not flat on top

[twillmo]

I've just received a wall mounted sink, and the top is pretty wavy (about 10mm deviation across the top). That last sink I got a few years ago was also not at all flat on top, and was a nightmare to tile.

I'm wondering how common is this? I'm not sure if I should send it back.

Rubbish quality basins are unfortunately more common than one would hope.

It's just for a guest en suite, so I was hoping to do it on the cheap. Maybe I'll return it and go for a better brand. However the offset overflow on the villeroy and boch compact sinks would sent my OCD nuts (they have obviously done it for space saving reasons)!

Tile first then mount the basin onto the tiles
