I wouldn't go less than 1200 width if you can avoid it. Depends on the scale of the house, eg a small apartment 1000 may be suitable, a larger, more grand home, you'd want it to be wider to be in proportion to the rest of the house. Without seeing the whole plan it's hard to comment too much - I'd hand it over to your Architect or Designer to come up with a few options :) A couple of ideas maybe are to make the other side of the shower (facing the vanity) glass - so glass 2 sides. That'll make it feel bigger than a solid wall. Also a wall hung vanity will give the illusion of more floor space and make the space feel bigger. All the best!

Are we just talking wall tiles here? What are you looking at for floor tiles? I'm thinking in terms of mixing gloss and matte in both rooms to tie them together and keep your customer happy but giving each bathroom its own character without being too different ................ if that makes sense.

Thank you @Creative Style Interior Design and @bigreader @Creativelychallenged - Thank you for your nice words. We are indeed very happy with the result. We also went through all these stages you describe, so don't feel depressed... there might be light at the end of the tunnel. Our research stage was so long and quite discouraging at times. We've always wanted to live in a queenslander, but our house is not one. This didn't stop us on going ahead adding some character to our bathrooms design (and kitchen). We started with the idea of making these bathrooms with a colonial touch but we found that it was not easy to find the elements we wanted (tiles, furniture, tapware) at a cost that would fit our budget. We learned that the type of tiles we liked (encaustic) were VERY expensive ($200+), traditional looking furniture was also very expensive... So we shifted to a more modern design...(not very happily though), and after a while of collecting ideas for modern tiles, furniture etc.. we felt quite depressed because we were compromising... updating our bathrooms with something fresher, but far, far away from what we really liked. In our view modern furniture looked very plain, streamlined and... boring, but we were doing 2 bathrooms (on a budget) so we were not prepared to spend a fortune, and we settled with modern. We ordered marble type tiles for the floor 900x600, and wood like tiles for the walls, and booked the builder to start demolition. Luckily for us National tiles called us saying that there was an error and the tiles they promised were not going to be available for 3 more months!!! Depressed again.... It took us so long to find something we liked (kinda) and now we were back to square one. Then my lovely wife said... Why don't we give it another go and try to make a more traditional design as we originally wanted.... So to make it short... we went back online with 'refreshed' energy and pressure (demolition already started) and found many things I coudn't find before: Floor tiles @ $25/m2 Subway tiles for walls @$16 the box on sale... Ensuite furniture and basin from Ikea Main bathroom furniture was an antique dresser we found in an op shop for $150 repainted and repurposed.... etc... In the end we spent approx $12,5K for both bathrooms in total :-) So, to summarise... don't dispair... just look in this website, on pinterest, magazines, google, etc... Play around with ideas and copy!... (you'll see that our ensuite is quite similar to the first photo in this discussion)... Good luck! :-)

Katherine, I am just curious about the look of the rest of your house? For example, what look is the kitchen and external look of house. I love your bathroom, but not sure if it would match the era of my house. I am beginning to think that in bathrooms, they really only look unique and have an extra "something" when the floors aren't the typical grey, charcoal, beige........not sure what to do yet with mine...
