You can consider these four measurements when selecting a shade. The top diameter, bottom diameter, side length along the slope, and the drop. The size should balance between the lamp and shade. You can do this: Assess the proper size by measuring the height of the lamp from base to stem, without the harp. Use that height number, plus or minus two inches as the diameter for the shade bottom. For example, if the lamp measures sixteen inches, then the bottom diameter of the shade could range from fourteen to eighteen inches.

Lots of ideas. If you go for a "grey" tile on the floor, make it a mid grey in terms of the intensity of colour but also look at a "cool" blue or green grey to match in with your blues and greens you've chosen. The picture of the grey tile looks quite a warm grey, what I would call "greige" (grey/beige). Starting to get quite personal now in the space but your gut will tell you what is best suited and works with your house.

It's a little unconventional badobbs, but have you considered a toilet with in-built basin and tap - these are very sustainable (although not for everyone!) and are perfect for tight spaces. https://specify.caroma.com.au/products/toilet-suites/profile/profile-5-toilet-suite-deluxe-with-integrated-hand-basin.  To answer your question, usually you need min 800-900mm or so for a fixed panel for a shower, however normally walk-in open showers are located perpendicular to a room, so that splashes and wet floors are contained to one end. Think of when you drop the shower head and it sprays water everywhere! In your case I would advise selecting a well made frameless hinged door - so you can still have a walk-in effect but a bit more protection from water spraying out everywhere. Try Reece; https://www.reece.com.au/assets/brands/244000/custom-glass-brochure-v1.pdf The vanity depth is going to be the issue here, usually we advise min 800-850mm clearance (although can go down to 700 as per Dr Retro House Calls) and can see from the plan that with an 800 bath and 700 clearance you only have 250 depth for your vanity when it's near the bath. You could get a vanity made up at 250mm deep with a semi-inset deeper basin centrally - that way you can make the vanity a little longer but with a workable basin. https://specify.caroma.com.au/products/basins/luna/contemporary-luna-semi-recessed-basin-without-tap-landing Good Luck!

I saw these today and they seem to match well with our wall bricks and roof colour and well priced too. Now I think I'll consider retaining wall options and compare to brick. https://tilemarket.com.au/product/trevi-grey-external-300x300/ Edit: definitely going with brick I think
