The unit has an incredible view and location. Imagine how good it would look if it was being renovated for owner occupier

Hi dreamer, thanks for the suggestion. Im wondering though, how do I treat the junction between the vanity and the fixed panel of the shower screen? The diagram I uploaded above leaves out the shower head, so there will in fact be a shower-over-bath in the above scenario, with a fixed panel adjacent the bath. If I have the vanity hard up against the bath, I'll need to tile the side of the vanity, no?

That bathroom has been brought into the 21st Century! It looks amazing

Like others , I absolutely love the colours , the rounded cabinet and mirrored wall unit , but the square tiles and subways meeting in that corner distracts from the beauty of the niche . You say the client fell in love with the square tiles -- I can understand that , but I'd suggest doing a row or two of them around those 2 walls ( maybe just below the height of the niche ) would have made it look like it was planned -- right now it basically looks like someone under-ordered tiles , so had to do the next wall in a different one . In fact , it's slightly worse than that , because one goes to the floor , the other stops 600mm above it and is white below , and us OCD people don't like that haha !
