I take my phone in the bathroom with me but I don't use it. I've dropped my phone in the bathtub and sink and don't really want to have to buy a new one so I just leave it on the counter.
I watch shows on my laptop while I take a bath because my toilet is right next to the bath. I also take my phone, laptop, or 3DS to the toilet because I have occasional stomach problems so toilet time is kind of unpleasant D:
Yep, if I know I'm gunna be in there a while I'll use it on the pot but for sure I always bring it in when I'm taking a shower or bath cause I like listening to music in there.
Nooope. I'm always terrified something happens to any device, plus it feels unsanitary since I'm a hygiene freak. There was one time I took my phone to browse when I went for a bath but I was the most paranoid and unsettling bath I've ever had. So no, never.
