I think this flooring from the Colour Flooring Company could look great. It's vinyl but great colours and finish and cheap Don't think this grey would nec go with your colour scheme but others would (or even white?).
If you're a bit squished for space, why not think about installing your shower over your bath? Rise Digital lets you switch between its showerhead and bathfill at the touch of a button - so you'll get the best of both worlds!
Super cute DIY Floating Shelves… These are easy and cheap too! Note: OK, MUST create these. Substantial, design and size flexible, I have a feeling these may be going up in more than one room. Already I'm seeing framed family portraits on these!
Love love love the Mother of Pearl tile on the wall with the light grey floor tiles, awesome feature wall and white everywhere else. https://www.subwaytileoutlet.com/products/White-1x1-Pearl-Shell-Tile.html#.VRCJJo7F-1U
