Hi. You may not be able to move the soil pipe to move the loo. Is the missing corner the boxing in of the pipes? This is the duo tub by omnitub which measures 1050 x 1050 which is obviously set in the same width bathroom as yours. It may be worth exploring to see if it's an option. If not large tiles so the space doesn't look busy with grout lines and a huge mirror will help. A vanity unit on legs will also help to give a feeling of space if you manage to find one in that size. Good luck!

Wow, thank you everyone for your extremely helpful advice and ideas. I had not appreciated the safety issue with the current layout as strongly, but you have swayed me. (Thanks Jonathan). First, as a few of you have asked, I’ve attached a photo with the bathroom dimensions. Hopefully this is legible! I like the shelf/utility cupboard idea, however I’m concerned that this would take away too much space for toilet/sink/shower area. Jules Mc, I think the toilet reconfiguration behind the pony wall is a brilliant idea. If we are unable to play around with the current levels, I think this is an ideal solution. Jonathan, thank you so much for these options. Unfortunately we have a wall protruding in front of the entrance to the bathroom, so I don’t think that there is room for a door to open outwards, or for stairs to be built outside. Man About the House, this is absolutely incredible! It maximises the space while still allowing for the fun/eccentric aspect of the elevated floor plan to remain. I would never have thought of this arrangement. Would raising the floors for most of the bathroom be a major added cost? I’m a bit nervous that the diagonal wall (currently next to toilet where staircase is underneath) would protrude too much into the walkway of the shower. But maybe there would be enough space, and could build a vertical cabinet or shelf to cover up this slope? Again, thank you all for your comment and your time, I’m seeing this project in a whole new light now!

If you shop for a space saving toilet there should be plenty of room for a full sized basin on the same wall. A p shaped bath would also give you a little more room at the shower end.

Options then would be:- putting them on the shorter wall opposite the sink: 800 wide shower (or 700) but 1m length coming out into the room as the entry door is offset. That gives a good sized shower. Then you have 1m tub space to play with for a deep tub. Then I would put the WC and sink on the other short wall so entry into the tub isn’t hindered. 1200 or 1300 tub on the 2m back wall with an 800 or 700 wide corner shower. Actually you could potentially have it so the wc is far left back wall with 1500 bath opposite the door and then a corner shower far right side. It’s all a bit cramped though with a standard or even small sized tub so do consider a shower over bath. You can get short rise baths if it’s an issue with getting in/out that’s the issue. Also shower baths with 800 shower area if it’s shower experience
