Thanks all - our belongings arrive this week so I will have a go at transforming the space with what we have then search for new things to add. We have quite a bit of art with strong yellow colors and also a Tibetian Chest with yellows and greens. Thanks again!

Actually, just reread a bunch of the tile places and they all say not to use in shower. Bummer - that's out. However would still love ideas on what to do around it and if anyone can think of a way to update the acrylic walls? Or maybe it won't be as bad with new fixtures/shower curtain in better lighting... fingers crossed... just trying to get ideas together.

Yes, I had noticed a lot of pics on Houzz, that's what gave me the idea! I certainly wouldn't put it IN the shower! We have a tiled shower, but the tiles only go as high as the glass surrounds, so there is about 30cm of painted wall above the shower, which is the part I was worried about with steam etc.

Add colour . Please add colour haha . Just a thought though , instead of paint ( its a bit hard for me to visualise everything from your description -- I am a visual person ) how about maybe those translucent blue looking tiles ( yes , I know , extra cost ) , you may even 'frame' them in the white tiles to tie in with the shower , or possibly do the blue instead of the white , or even do the shower in them , and have the rest your 'white' walls . And when I say about those tiles , you can get them in square or subway or even long skinny ones , or even long and skinny but with long skinny darker blue and brushed ali ones too -- in other words , have fun and add interest !
