Hi Thank you for your suggestions. The Tiler has been very helpful and has sourced some 10mm chrome metal strip to silicon to floor to act as a barrier to contain water runoff. It looks ok and is the least invasive option to cutting into new floor tiles to put in a grate drain. Yes we have spoken to Territory Construction Group and Consumer Affairs for advice.

hi we have about six months ago now, re done our bath room , similar size to yours, and , i can take some photos and email them to you , we have maximised space, and walls , put in a white stone bath under the window , it is a metre in width , with a cool water spout coming off the centre under the window we pu t afalse ledge in to sit , candles etc on , , we tiles floor to ceiling, off white , wall mirror cabnit with three mirrors , inset into the wall so its only sits out a we bit from the wall tiles , floating bath room vanity , so that it makes the floor space look bigger , . matching stone square basin sits ontop of the vanity to one side so plenty of room to sit all your bath room stuff when need be , seperate shower all tiled as well , with inset , shelves for shampoo etc, also , when you open the bath room door and walk in when you close the bath room door behind it next to the shower is a very narrow floor to ceiling shelvec for towels, now the hole is there we jaust havent got the shelves put in yet. , we gt loads of comments as the bth room dosent look small evn though it is , , most expensive item the sqwat extra wide stone bath , made to order basin / tap ware and shower spray thing ,oh and the white stone vanity which we had made to order as well , due to the sizing .

@AAB That Ikea one looks like it has good dimensions from above, but I think you'd find 20cm too shallow to double as a useful laundry tub. If you could find one that was twice that depth… I did encounter such a sink in a long-stay apartment hotel I stayed in recently. The bathroom was fitted out with a combined washer-dryer unit and the "basin" – while styled aesthetically like a bathroom basin and oval in shape as well as rounded in cross-section – was really big. You could have washed a large baby in it! So clearly that kind of thing is available. It did require a fairly deep vanity to mount it in, but that was there to accommodate the depth of the washer-dryer anyway. The only thing with a deep vanity is you absolutely need to mount the mirror on a cabinet to bring it forward, not directly on the wall. If you don't do that anyone who is short and/or short-sighted has a hard time using the mirror for practical purposes such as shaving, inserting contact lenses, or applying makeup. (Yes, I discovered this during my hotel stay too!)

Many thanks, much appreciated! Loving photos 1 and 3 for the tiles and 2 for the vanity! The black fittings look great 🙂
