MB Design & Drafting, I have to contradict your comment about having only 1 floor waste, we have a large double shower with only 1 floor waste, ours is in the centre of our double shower, our tiles are black and by the time we get out of the shower the water on our shower floor is gone, I always clean the tiles and glass before leaving the shower, I leave the fan on while we dry and by the time we are dried our shower floor is almost dry, we have no trouble at all with only 1 floor waste.. Barbara, we have the same problem, which is not a problem at all, my husband likes his shower much hotter than me but we have our showers turned on to suit each other, we have a small seat at each end to sit on while we wash our hair and feet and each others backs.

For storage, I used a mirrored lift up cupboard door above the sink area in my very small ensuite with some success. We put power points inside the cupboard too - it was a very good place to have them as the door lifts up & is out of the way. I also used some of the wall space to allow slightly deeper shelves, without the cupboard jutting so far into the room. The cistern was recessed into the wall cavity, (in our case below the window) & it worked well to save a little space in the room. Photos are not very good, but I hope you can get the idea.. It worked very well. The ensuite was 1mx2m. We use vertical towel rails. They're really good & very compact, but do make sure the electrician installs them up the right way. They work on the heat rising principal & do not work well upside down as ours were installed!Hope this is helpful. Good luck.

Unfortunately, I do not have the exact measurements nor do I know what the walls and floor are made of. It's only a one storey house and we want to live there for at least 10+ years so we want to get it done before we move in as it will inconvenient for us given that this is the only bathroom in the house. Thanks for the suggestion Kate, I never actually thought of opening the other side of the existing shower. Just thought of something like below.

Oklouise and Siriuskey and others thanks so much for input. I’ve attached the version we think works best, but would like to configure the other space as a semi ensuite with hall access also, maybe we need to include the corner storage space as I have shown to make it work. Siriuskey, I have taken your advice and removed internal angle walls for fireplace,tv and butlers pantry and have realigned the other small wall as mentioned. We will reconsider when we are at built stage, how to define the spaces...I am liking the idea of cured walls to soften the other angles. Just wondering if I could stretch the friendship and have one of you re draw the small bath room into that space as shown I would be very grateful.
