Do you want this to be a big reno? meaning, will you replace things totally or do you want to work with what you have mostly? will you add a toilet to the bathroom? if you replace the vanity, you can put in a larger one curving around the corner with a medicine cabinet above. If you replace the shower with one flat on the ground, you can also put in clear doors for bigger visual space. how about re-painting as well

We have a 900x900 shower and it's plenty big enough. Neither of your proposed layouts looks that great, to be perfectly honest, sorry! In the first layout, you could improve it quite a lot by swapping the toilet and vanity (centre the toilet under the window on the bottom right of the picture if possible), and having the shower door on the other wall (beside the door). Then, you could have a towel rail on the wall beside the door (i.e. behind the door when it's open), which would be accessible from the shower but hidden when the door was open. An 800x1200 shower might be a good size for your space. You'd have to choose a toilet that doesn't protrude too far, plus a narrow vanity. With that layout, you could have a long but narrow wall-hung vanity, with a big mirror covering the wall between the windows, which would make the room feel bigger and would give a good amount of storage.

If you can narrow the linen cupboard, then you do do a similar layout to that GB has shown but with a changed door swing, swap the basin and WC, putting the WC on the wall beside the door so the WC is concealed behind the door.

Hi Fernando. Not sure if you have considered the shower door in your layout, either the bath traps or it collides with the bathroom entry door, some awkward gaps by the bath and vanity there too, cleaning will drive you crazy. What do you think of this layout? This means you can have a 900 x 1200 shower with a sliding door and just room for a towel rail next to the vanity. Let me know how you go!
