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.

My favourite design things are things where if someone suggested them to me I would've said, "Nope, nope, nope, uh-uh, no" and then I see them in situ and I go, "Hmm, yes". My point is, I love that shower screen. :)

Looks great!! Love the concrete sink!

Hi jay and Melinda. R u still working on layout? Have you thought about having an internal separation in the space. Try this, sorry I dont seem to have success adding images. Off bedroom hall put an opening, could be sliding door, roughly 1200 from your main entry hall, centre of opening at 1600 offset. As you enter this doorway, on left is sliding door to toilet and on right a vanity. The toilet is rotated 90degrees from where you have it. Vanity say 1600 long and toilet room same. Toilet internal width 800. The vanity is set in from the eastern wall 500 to allow a narrow but 1600 long linen cupboard on entry hall outside bathroom. Hope you are following me. Back in the bathroom area beyond the toilet and vanity is a wall with sliding door to washroom. In there I think you would fit a bath on west wall, shower 900w x 1200d on east wall in south corner and another smaller vanity around 900 on east wall. This is creates a powder room on outside and bathroom beyond. Sinks in both areas for flexibility. The 1600 vanity, do one sink and put a makeup area with stool under bench on far end. Hope this gives you food for thought. All the best
