haha - my Irish friend used to refer to a sponge bath as "tits, pits & naughty bits"
Here in Ontario, it is often possible to have a publicly funded homecare service provide a personal service worker to come to your home to help with bathing where safety and mobility are issues. Doctor usually needs to order it & there is no cost to user. Is there anything like that in BC? Also, the same agency could send an OT to the house for a safety assessment, particularly re bathroom equipment in your case. A tub transfer bench, possibly with a back on it might be helpful to you. Sometimes these can be rented. Sometimes at the hospital, people who have to wear zimmers prefer to use a wheelchair with elevating leg rest - gives good support to the leg while sitting & makes getting around a little easier in many situations.
Did this particular fall occur at work? If so, Work Safe BC should be covering the expense of any equipment, attendant care, etc.
