They are everywhere on American house and some look quite good. If you want one, then have one.

It's all in the planning, get the floor levels right and you will never have a problem. I've done 4 bathrooms like this, all in small areas with only a 900 or 1000 screen. 1800 wide is pretty wide, as the screen goes in last, I would suggest that you re access at the end. You do get a bit of spray in front but it all drains back, if you have a door, the water drips off both you and the door when you get out. Another thing to consider is super easy maintenance. Quick scrape with a squeegee, easier to mop, no runners to trap dirt and mould.

Depends on height of the ceiling,and size of your room. ceilings up to 2700 tile to ceiling ( replace ceiling, it is not a good look new bathroom with old ceiling, unless featured ceiling, you need to remove cornice, Tile all walls to ceiling, add new cornice for professional look ) Have you thought of feature wall behind basins, same as floor tiles ?

Looks great!! Love the concrete sink!
