Hi Catherine, you're right they aren't commonly seen or available in Australia, which makes them even more distinctive when you install them here. It's very much something you would see in an upmarket hotel. Plenty of selections from America and Asia. Though the one u've found from Dorf is beautiful.

if each hand basin is 500mm and the counter is 1800 there'll be 800mm left to be divided into three portions...perhaps 250 on each end and 300 in the middle will give a symmetrical feel anything else will be skimpy but also consider the depth (front to back space) and given the option i would opt for a deeper counter for extra space along the back...50 to 100mm extra depth could be very useful

good points SK and Eco thank you. Looks like I'll be going with the flick tap, offset at 2pm to the right of the round vessel basin, mounted in the centre of the top of the vanity (not semi-recessed). Any thoughts on whether the vessel basin should be bang in the middle, or offset to the left slightly to balance the tap being on the right?

However, if you are just after looks, then the photos in your link, appear to have a 350mm basin which is leaving the 100+mm between front edge of vanity and basin. It does look better, but is that size basin too small for use?
