Shower stool or chair (Castro Valley)

My daughter recently took a fall and now she's in a leg brace and we only have a shower so she needs something to sit on so she can bathe herself if anybody's got a shower stool or chair that they don't need please let me know and if you can possibly drop one off in my driveway as I don't drive and I don't have a car but she is in need of one so she can take a shower thank you so much in advance
