your toilet really tight, I will advice not to do full shower glass panels.

May be a small one at basin, then using sliding curtain will do.

Here is my suggested layout for you, cheers !!

Since this is a studio size unit, I suggest you using 2 different ceiling design to create 2 activity zones for better visual appearance.

means having ceiling only at sleeping area and remain expose ceiling at the other activities area.

Expose ceiling will also make ceiling higher so your studio won't feel cramp.

Can consider paint the expose ceiling into one of your favourite color to further stamp in some uniqueness for your living environment.

Play with some different lighting as shown on attached image below for you, Cheers!!

I see, can still have two different level of plaster ceiling with slightly higher ceiling at study activities area to achieve the same visual impacts.

Hope this help 🙂

The sleeping area I suggest using 6 inch led downlight.

If you follow having the recessed light trough then 12w should be enough unless you prefer bright ambience then can consider 18w.

you will need more nos if you prefer eyeball spotlights examples 8 nos instead.
