I'm guessing this is the new self cleaning windows. Perfect for a double story house were you just can't get to the windows but I agree it's not necessary for a shower screen. You can just get them sealed, then you just wipe with a microfibre cloth.

I'm also considering a waterfall option instead of a nib wall, but with a solid surface (acrylic) bench top - same material used for bathtubs, basins, shower floors etc. My builder did not believe there would be an issue. I still need to speak with the glazier on the options for the glass and bench top junction. What that could look like. Based on what I've seen how a shower screen are connected to nib walls, the same approach may apply. a b - Have you investigated any further on this?

Hi Austere. Thanks for your comments. I guess it depends on your scope really. This renovation combines three rooms into one, so a fair bit of reframing, and moving plumbing around to achieve the clients desired layout. The laundry is behind sliders, behind from where the pictures are taken from, so this is a very large room. $15k is achievable, but you would need to be working on a more regular sized bathroom, stick closer to the original layout to save on plumbing & electrical, probably scale back a bit on tiling and fittings, and go to a standard sized cabinet shower rather than a large customized walk-in shower with glass to the ceiling. There are certainly more modest options available to meet budget. Please let me know if we can be of any assistance 🙂

Sorry no help here.....Have you used the bath yet? I would be concerned that if the bath is not level on the tiles, that, when full of water, and people, the bath will move off the wall on side and the back. The bathroom looks Interesting, but that small gap between wall and bath, is very troublesome. If you put a shelf there, it will become even harder to clean.
