Right now its so much with me being unbalanced and unable to hear someone ask if i'm ok and stuff like that. This is in the main bathroom it does actually lock. In our back bathroom thats in my parent room, the door doesn't shut enough to lock because the house is slanting and has it in a bind..
They mainly want to be able to get to me if I fall or something while taking a shower or even while trying to put on clothes, which is still hard.
As i keep saying I have a lot of problems from my accident, hearing and walking being the biggest two..
The best bet (and what we do at my house) for the bathroom is:
For showering:
1) I let anyone else in the house know I'm hoping in the shower (that way THEY will listen for anything - doorbell, dogs, phone... me crashing and splitting my head open etc
2) I leave the bathroom door slightly ajar (closed, not latched) and we have a sign that goes on the door handle - a Foam kind from the craft/dollar store- that says "STOP" (it's red with a stop sign) ... the other side is Green and says "GO". I flip the sign to "STOP"
3) If anyone NEEDS to get into the bathroom (to use the facilities) ... (the shower curtain isn't see-thru at all, so they can't "see" me) - they will flip the light switch off and on 4-6times and wait for me to say "YES, do you need to come in?" (if "YES", they respond my flipping the lights again & I reply "ok, come in") - for us "YES" is always acknowledged by flipping the lights a few times.
If they need something else (ie need to tell me something RIGHT THEN) then they will NOT flip the lights and wait for me to say "Do you need to talk to me RIGHT NOW" ... if "YES" they flip the lights and wait for me to respond (I arrange the shower curtain so I'm covered then call "come in").
This is where knowing a few basic signs is helpful such as :
"DOOR" - ie someone's arrived to see you
"PHONE" - some massively important phone call that can't wait 15mins lol
"FINISH" - you're running late/have to get out of the shower now etc
"ALARM" - there is some sort of emergency (fire etc)
It might also be helpful to have a few small dollar store white boards & pens so that they can write short messages to you if needed.
One a "shower safety" note ... one thing that you might want to consider is having a grab bar installed in your shower (the bar & install should be covered by your insurance due to your accident). I actaully have one in my shower because I sometimes have balance issues - and because I have Fibromyalgia and some permanent injuries from an accident (weakness, mild muscle atrophy, dizziness, light-headedness, major fatigue, balance problems especially if I close my eyes ie to wash my face/hair etc) Having the bar is a HUGE help not only for me, but everyone else as well
