Hi All - taking on board your comments I have come up with three variations. Of course would love your comments! The distance from vanity to WC in plan 1 is approx 60cm - it could be made a bit more. This falls within the guideline you posted (23inches). More space could be created by making the shower a bit narrower (shown on all 3 plans as 1m wide (39 inches). I don't think there is quite enough space to divide the room and the problem with the idea of the bath right in the middle is that on a practical basis we would have to walk around it on a daily basis to get to the shower! Could quickly get very annoying!

The toilet was going to stay in the current position. Bath along the back wall and a basin maybe on the right hand wall. I'm just struggling for ideas and don't want to start the first fix plumbing until I'm entirely sure on layout Thank you for your response :)

Query - why does the back wall of your shower have a slanted bit at the bottom? Is there something behind that, and under your storage area, that would mean you can't use all that back wall? If there's nothing there, and no problem with that corner, then: 1 - You could leave the bath where it is. Upgrade the panelling around the base and maybe put a little door in the panelling for under bath storage of cleaning stuff etc. Maybe even upgrade the bath itself too? And then move the loo to the back left corner, facing the window. Move the basin closer to the new loo position, and further away from the door, and build a low storage 'wall' all along that side wall, with the basin on it, and the loo also. The top of that new 'wall' will be a shelf for putting nice candles etc. Then, mirror all across that side wall, above the shelf, to increase the light and spaciousness. This is what we had in our tiny bathroom. It's more linear looking, with the main items on opposite sides of the room. 2 - Move the bath to horizontally across that back wall as you suggested - if space allows for the length of the bath. I think there will be enough space for a shower, even with sloping ceiling. Try standing up in the bath, and see if there is room above the tallest person's head. If you attach a pump to the shower, you will have enough power for a good shower. Maybe use mirror type tiles on the back wall above the bath to reflect light, and increase space. Move loo further into the room. Consider putting basin beside loo if there's enough room now, under the window and connecting them both, with a similar streamlined idea to above. This will square out the room a bit, leaving central space. You will also have a little space then on the left side where the sink was. Maybe a towel ladder could go there, or nice storage basket for loo rolls etc. 3 - Go and talk to Carolina in the Tubs & Tiles in Sandyford, in Dublin. She's amazing, and is a qualified architect, so she really understands space. She re-did our tiny bathroom. It looks amazing and has already won a prize! We took out the bath for a walk in shower. Which is my next suggestion to you! Even if you have small toddlers etc - you can always get a big plastic basin for baby bathing for a couple of years, and leave it in the shower. We left the sink and loo along the left side, and they're connected with the type of shelf I mentioned above. Good luck!

It feels a little cramped to me as your access to the bath is so restricted. I’ve just put this layout together that might be worth a try. (it would require a slightly smaller bath) if you can, get some boxes in there to represent furniture and move around it before committing to anything. Also, are you planning a freestanding bath and tap?? this might look squashed in and therefore make the room feel smaller (also really hard to keep it clean round the back) I would consider a back to wall bath with the space you have. re towel rail, bit stumped on that too, could it go behind the door??
