I love it, and are considering this myself which is why I can offer an insight to installation. Yours is luckily freestanding, however I would install this central to the long part of your L and enclose it within cabinetry, actually yours is Likely to just be faced with fake doors and no carcass behind, still a place to utilize storing buckets or baskets, even laundry powder, just not a standard cupboard. I would then actually install a stone benchtop making this technically undermount trough. You would still have the practical size and aesthetic impact this concrete relic has to contribute. Only, with the bench top area to make it a useable space.

Save big money on importing one from the UK and spend it on design to make the space work for you without the need for such an impractical solution. There are some cute, tiny wall mounted hand basins which would be a neater solution. https://www.reece.com.au/product/basins-c448/wall-mounted-basins-c452/axa-cento-mini-wall-basin-right-hand-with-fixing-1-9505814 If there is no other option here is another type of toilet/handwash product, but I don't think it looks any better than the Caromo design, although overcomes some of the impracticalities mentioned in the previous comments. https://www.reece.com.au/product/basins-c448/wall-mounted-basins-c452/roca-w-w-integrated-washbasin-white-5-star-9505427 Best of luck, Dr Retro of Dr Retro House Calls/Dr Retro Virtual Visits

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?

Whilst looks ate important functionality is key so you are right to question your choice. Your plumber can advise further. But mine said tap needs to reach over the plug whole. Tap should not obstruct you when you lean over to wash face, rinse mouth, wash hands etc. splatter would be reduced by a higher bowl but it is about the bowl depth and the water flow rate, which can be turned down by your plumber on commissioning the tap. Also consider if it will obstruct opening if a cabinet door on wall. Good luck
