Personally i love the 40mm but if you think about it the benchtop itself is not 40mm completely, it's around the edges so you're paying heaps of money for something so small... unless my builder is cutting cost and being shifty with me!
LOL! not just your builder Pearz...
the standard is 20mm bench top with 40mm edge (or more).
LOL good thing otherwise I'll be pretty damn annoyed!
It should be all over for the amount they are charging us!!
