could you post a pic

How big is the window? Why does it need protecting, exactly? What's in the bathroom now?

Hi, I need some advice on what colour I should paint my family bathroom. It has dark grey floor tiles, freestanding shower, bath and wash basin with with the same grey tiles behind. It has a mahogany brown window and window still with frosted glass. It is painted Farrow & Ball Lichen Green. It's very dark and I need to brighten it up all suggestions very welcome. Thank you.

Hey rinked, Thanks for the idea. I had considered that before, but wan't sure about taking quite that much out of the room. It would be an extra 2-300mm but as per your sketch I hadn't thought about leaving the nook behind the door which lessens the incursion (and in the bed room that space could be used for storage too). We are moving the soil pipe to the side of the house to allow for the bifold downstairs, so the toilet on the outer wall as per your sketch would really be better. Of course we could use a pump or so, but that's not ideal. Bath drainage could also run out that side too. We are completely renovating the room, everything is coming out and it will be tanked and retiled etc, so seams aren't an issue. My main consideration for having the toilet and vanity on the other wall is to perhaps conceal the toilet with a false wall, and also so that the light from the window (extremely bright as south facing) isn't to the side when looking in the mirror. Thanks again, lots to think about! EDIT: Mocking it up, it could look something like below...
