I'm surprised to see someone recommending Villeroy and Boch toilets, and would love to see what they think after a couple of years. We were recommended this brand by our supplier (Hardware and General in Brookvale). It was a lot more expensive than the others, but we liked the design and we were happy to pay for something that we thought was better quality. We have had nothing but problems with it, and when we went back to the supplier, they contacted the company and they just said it was past the warranty period and they couldn't do anything. The rim is unglazed, so impossible to clean (the more you try to clean it, the dirtier it looks), there are a large number of cracks, and where the toilet seat connects is a dirt trap and difficult to clean. We have the original 1940s toilet from our home in the outside bathroom, and it looks immaculate. I would never recommend Villeroy and Boch - the product as well as the after sales service are terrible.

Such great ideas from everyone. The smaller the space, the more creative you need to be. A friend of mine has a tiny ensuite which she turned into a "wet room" and some of her Reno ideas are: Back-to-wall toilet (less space, easy to clean), In-wall (cavity) cabinet, Wall hung sink with a built in side shelf (with lovely chrome trap/plumbing). You do have to waterproof the ENTIRE room to have a wet room but don't need a shower door. She also tiled about 30cms outside the ensuite door (in the bedroom area) to save the bedroom floor from any water damage which turned out to be a great idea. Good luck with the Reno and I hope you post your "after" pics.

I would suggest the banksia stylus, I have this as my main toilet. We also have the caroma Luna in our ensuite, the banksia which I got from plumtec (wa) which I think is part of reece, is a much better toilet than the caroma. Wish I had got another banksia instead. I have also been told that caroma's service if something goes wrong is not great, they donot care as they are a big company but I hope that is not true. All the best.

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!
