Hi There, as a general design rule, toilets should always be the last thing seen when walking into a bathroom so i would look at asking the builder if he can move the door slightly to the right, then put the WC on the other side out of the way. I'd then look at moving the vanity in front of the window or just to the left hand side as well. You might also want to consider a shower over a bath as the bath and shower wont fit next to each other either (unless you want a half size bath). Good Luck!

If you don't use baths, delete it from the design. A walk in shower with fixed glass screen was the best design I came up with a decade ago. A large vanity for impact and storage facility. Sliding door to maximise space. As stated previously, WC should be next door as design above. Should be least noticeable. Good luck.

I would have the door moved closer to the centre of the room(around 700mm in)privet the bath so that it is along the wall that has the window. Put in a larger shower, have a large vanity that could go along the whole left hand wall. Have the door swing and toilet as in the drawing below

Hi Katie. I've just finished a reno in a bathroom approximately this size. it looks like the toilet is currently on an exterior wall. if this is the case it can be costly - or not possible to relocate the plumbing. Yes, I know cisterns can be installed in the wall. My plumbers are wary of these ....try fixing a fault without cutting a hole - or holes - in the wall! If you are restricted to the outside wall, I would install a sliding door (gives you more space in the actual room). Leaving the bath and shower where they are saves $$$. if you move the toilet further to the left and install a wall-hung vanity under the window, you could also add a 'half-wall' to the toilet area for privacy. (Wall-hung vanities open the room up. This plan would give you great space on the left hand wall for storage and/or laundry hampers, You could of course switch the bath to the opposite wall, and move the toilet to the current bath area. Moving the door to the right AND installing a slider, would allow this. (BTW I just installed a 1700 bath - 1500's are available too.) Hope this is not too unclear! Enjoy the process!.

Definitely make the door a cavity slider.

I hate our concealed cistern toilet. Many leaks with major problems fixing it. Am removing when I can afford it.

You can get close coupled toilets that are space effective.

Made you an example of a bathroom I'd like to use (one of many options).
Double shower, but single sink (we don't need much time at the sink, but love to shower together (also very handy with kids). I don't mind seeing the toilet when I walk in, but not looking straight at it is nice. With two cabinets at the same height and a wide mirror above, one can comb hair while the other brushes teeth.

Make sure your ideas and the main drain are on the same line ;)

If you'd like two sinks, place the tub under the window and a sink on each side. Shower on the wall below, toilet next to it in the corner. This will leave less floorspace. Not my preference, but just to show you.

And another rather nice one. Not as much open floorspace as in the first example, but a somewhat separate wet corner. Ample of daylight when standing in front of the vanity. And loads of storage space.
