Re the asbestos thing (and don't take this as pro advice...cos I aint) but if it looks like, quacks like it then it MIGHT be it. I thought I had asbestos walls (cos everyone said "it might be asbestos"...similar to some kid who may have been Jake Gyllenall saying to Arnie "it might be a toomore"). My walls were not asbestos. However I did find out that you can remove a certain square meterage of asbestos (depending on state boundaries) without have expert (very expensive) assistance (check the state rules). If it "might be" then be careful. As you are tiling over (therefor not cutting, grinding, messing about with?) then stay cool and tile to your tile glue's content!

I only specify an overmount sink for clients if the benchtop surface warrants one. The last time I did was because the client wanted a timber benchtop. I managed to find a beautiful black quartz composite sink that worked well and looked like a feature in the kitchen because it matched the colour of the cabinets. My usual go to sink is definitely undermount because of its aesthetic and practical advantages. Small chips can always be smoothed out if need be but really, there is no substitute for being careful!

Thanks how2girl, yes it is similar. The basin I have posted has quite wide rounded corners and quite a fine edge to it which then seems to taper down gently. As its teamed with an Italian tap, wondering if its also from that part of the world? Any leads from International houzzers? - its really a very nice basin! generous and not too utilitarian.

Try Supersteel Australia. They are located in QLD but have NSW distributors....
