Just noticed a series of relatively superficial, hairline, cracks in
our porcelain bathroom sink. The very fine cracks in the porcelain
surface radiate out from a center point suggesting that something hard
dropped there causing the resulting cracks.

Is there a good DIY repair that would be relatively invisible or does
one need to bring in a specialist or even replace the sink.

Again, the cracks are very thin and superficial (and certainly not
structural) so unless the repair will be prett much invisble, I will
just probably leave it alone for now.

Thanks!

What's the replacement cost of equivalent sink? Could you replace the sink
yourself?
