Help with wording

[donutsweeper]

UK peeps, a question on wording (that I'm too embarrassed about to post over at  dw_britglish .)

For a US character I would say that, after receiving a a life-altering injury, a character is barely capable of going to the bathroom by himself.  Bathroom, in this case, would mean the ability to use the toilet and wash up and whatnot.

Would the UK wording be "use the w.c. (or is it WC) by himself" or simply toilet or lavatory or....?  Help!

We use 'power my nose' and 'little girls/boys room' here too, but it sounds a bit too polite/silly in most contexts
