We just got done getting rid of our tub turning it into a shower as we never used the tub. I've seen those adds and hope I'm able to see one of those some day as I'm curious how it is designed to stop water leaking. BTW ............ sorry about your Wife. Health issues are so hard to deal with. Google .......... FECO and Parkinson's. FECO stands for full extracted cannabis oil. Edibles for pain. You tube has some videos on it as well showing a man with un controlling shakes after rice grain size oil the shakes stop. Part 3 ............ https://www.youtube.com/watch?v=zNT8Zo_sfwo&ab_channel=RidewithLarry If this interests you message me and I can call you we can talk about it. I don't sell it I grow my own use it for pain give to others around me who have cancer etc as it's expensive at dispensaries some can't afford it. If one is caught sending it in the mail big pharma makes sure laws are in place to protect their profits. But I can give you more info and advice what I'd do if in your situation and send you links.
