Hi Chloe. We had a contractor over, and it looks like all plumbing can be moved. Our initial idea was to have a walk in shower at the top of stairs, where toilet and sink currently are. Toilet and sink/vanity would move down to where bath currently is. We do not need a bath in this room, only shower. Cheers!

The raised bit would make a great utility cupboard. Then you could remove the 2 steps? Would this leave room for a shower room/wet room?

I’ve never seen such a complicated stair box. It all looks far too dangerous to put anything above the steps. If you can fit a shower, loo and basin in the lower part then build a cupboard around the upper bit and remove those terrible stairs completely as suggested by Jen P. Love how as you get up the steps there is a shelf to whack your head on on the way Up! I’m sure whatever you do will be an improvement.

Woke up thinking about your bathroom dilemma this morning (I really do need to get out more!!!)
Totally agree that shower on the raised level is an accident waiting to happen.
If levelling off the space, even reducing it slightly, is out of the question I would leave the toilet where it is but build up the stair bulkhead and to a false wall with storage/display shelves at the top. Obviously repositioning the wc in any way is going to require plumbing changes but you'd be keeping it as close to the soil pipe as possible leaving it in the exiting area area. I'd then consider a half (pony wall) like you see if a lot of hotel/USA bathrooms which would conceal the loo and reduce the impact of the unusual layout.
You can then decide, depending on the width of the room, whether to bring the basin /vanity down to the lower level with a fab walk in shower. This is one I'd love to see the end result - a silk purse out of a sows ear is really possible here!

I like the idea of the storage area at the back and the wet room at the front, at least it would look a little more normal. What are your dimensions?

Either that, if you don't want the storage, then raise more of the room as Jonathan says, to make it less hazardous.

This is more what i had in mind. I put a walk in shower in that walks toward the end wall and the bigger platform.

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!

Still do'able, i would move the steps forward towards the door, I don't think building new steps and a frame for the shower is going to prove that expensive, and it makes sense for the room over all.

I made the platform at the end deeper at 1140mm instead of your 890mm.

It's more awkward to put the shower across the back and move everything else. Besides which, I don't think you'd have much room with the shower across the rear and exiting towards your hub, although that is an option.

You must have waste going out under the bath, so you can utilise the same waste for the raised shower tray.

You did say you didn't want a bath right?

Hi Man About The House. This is unbelievably helpful.

I think your idea utilises the space extremely well, and I love your suggestions for fittings. And you make a good point about this layout utilizing the current waste pipe, which will hopefully save some time/costs.

Yes, we don't need a bath in here (we have an en-suite bathroom where we will put in a large tub).

You are more than welcome, good luck with your project. Can't wait to see what you end up with.

So I am probably 3 years to too late, but I just got this idea to integrate the bathtub with some kind of removable decking, so the space could double as a floor and a shower.
