This was the link which shows above in the dilemma but it has changes you will need to scroll through the bath styles and check the info attached to it, lets know how you get on cheers https://www.caroma.com.au/bathrooms/baths/vibe/vibe-1700-island-bath

Are you kidding us all? That looks fantastic!!! That bath and spout are spectacular and both look absolutely amazing. The spout looks excellent where it is, you do not want to hide it, show it off and no it does not obstruct the look of that divine bath. Well done italiangal

I think you have answered your own question in your comments. Unless for some Australian standard you need the overflow, I would just install the standard plug.

Kate's idea of using the pantry space is an excellent suggestion as a toilet can comfortable fit within 800 x 800 alcove with the end opening towards the bathroom and closing the extra door from the laundry toilet could allow enough space to squeeze in an extra handbasin but please double check all the dimensions ..measured from wall to wall the bathroom has to be more than 1200 x 2, the laundry more than 1200 x 2 and the toilet size isn't right or there wouldn't be enough space to open any of the doors??
