You could consider ripping out the shower base and tiling the existing 830 wide and extend that all the way to the existing bathroom wall at the opposite end of the bathroom wall. It would create one wall at an angle but with a seamless glass shower screen and a new tiled floor and walls it wouldn't look out of place. That would allow far better body manoeuvring in the shower.

I adore closed in showers--they feel private and luxurious. OTOH, I feel both exposed and uncomfortable in glass ones (despite the fact I'm the only one in the room). Plus I hate the upkeep cleaning the glass.

Thanks Hanna, it's as green as I could achieve with the look I wanted. The mirror is the previous one with a new surround and the tiles are by Porcelanosa. The towel rail, light fittings, shower enclosure, timber vanity and the grates (shower and floor) are Australian made. The imported granite on the vanity top was cut to size and fitted locally.

Hi all. Thanks so much for the feedback! Both options above are better than what we have. To answer the questions, this is our main bathroom. We have an ensuite and a powder room so we don't need to separate the toilet. We could move the door but only along the current wall. The reason there's a step in that wall is we have a cupboard on the other side of the wall we'd prefer to keep but we'd probably sacrifice it if it helped.Yeah I agree a shower bath would solve all our problems but wanted to stay away from that. There's also a window on the back wall over where we had shown the bath. It's a narrow high level window. 1900mm to bottom of window. It runs the length of that wall. Thanks again for your help!
