Having helped my mother in law with her shower room (she has MS) and helping a friend who just broke her leg ... the bigger shower is a great decision, but I wouldn't build in a bench. down the track if she needs to sit to shower, she will probably need a shower chair with arms to lower herself up and down and to be able to move it around if someone is helping her shower. then anyone else showering can just take it out and enjoy the bigger shower!

Thanks for all the input! Lots to think about here. To answer the questions, to the right of the door is a bump out from a linen cupboard in the hallway - we won't be moving or resizing that. There are no windows (all walls are internal). Yes, we were thinking of a 'ladder' style towel rack to use some height. The doorway is 700mm and the toilet wall to the doorway is 1150mm. We don't have a specific stool or vanity selected yet. Re why we wanted to include a seat of some sort - I use the edge of the bath every day, both for putting a foot up while drying off or applying moisturiser etc, and for sitting on for foot care / clipping nails etc. I have to admit that I hadn't considered just using the toilet seat as I'm used to those older, slightly domed lids that 'buckle' if you sit on the centre of them. But I can see now that newer toilets appear to have flatter and more solid lids, so perhaps that is an option afterall. We also wanted to select a stool that could go in the shower - my husband is quite sporty and would love a sit-down massage shower on occasion. I'm thinking now that we perhaps just have a 'wet' stool live in the shower recess (bottom right corner of the plan should be out of the way) and then the toilet lid for 'dry' use. The last picture shared by dreamer is a very nice solution, though if we extend the vanity all the way to the left hand wall we'll have to look at narrower towel racks. Hmm, all very interesting! I'll experiment some more and probably come back to bounce some more ideas off you all. Thanks. :)

the last option with shower and toilet either side of the window and hinged entry door opening towards the laundry cabinet... hinged door is cheaper and offers more privacy and solid core hinged doors will improve sound reduction and the back of a door can support extra towel rack and/or clothes hooks and the tall window needs only be same as top of door height (about 2.1m) and if necessary simple hinged doors on the laundry nook will use the least space and are only open occasionally

Why is there no storage under or above the vanity? I’ve read the post three times and try to refrain from posting negative comments but for an ensuite this would be a real pain to get ready in.
