How to get urine stains and smells out of clothing?

So my grandma is having a lot of accidents. She's using the walmart brand of depends and while this helps when it's a real accident. Most of her accidents involve her walking to the bathroom, pulling own her pants then peeing before she sits on the toilet. This results in pee everywhere even in her shoes, in her clothing and on my tile floor. This house was just recently built and we have only lived here two months and already the bathroom smells of urine. I'm trying to use clorox, kaboom, lestoil and none of these items work. I have an airwick freshener in the room but that doesn't do anything to mask the smell.

The toilet smells strongly of urine too since she uses a plastic toilet riser. I have tried bleach tablents in the toilet, lestoil hanging tablets in the bowls, spraying with various products and still the place just smells like urine. I never cared much before as my grandma had her own special toilet but now her toilet is the main one in the house and connected to the living room so the smell oozes out there. I'm trying to keep up with all of it but honestly I'd have to do laundry everyday to really keep up with the urine stained clothing and have to spend hours cleaning the bathroom everyday to keep up with her every hour to hour and half bathroom use.

Has anyone had any luck with this issue and how to get the urine smells out of clothing? I'm considered because since losing my mom, my dad has been really depressed so I am thinking of introducing a cat into the house. I don't want the cat having issues peeing everywhere with her urine stains being strong in the house.
