Need our bathtub turned into a walk-in shower

Here I am asking again. Brian is having continued mobility issues and our bathtub is presenting a problem. There are plenty of programs for seniors to get these type of accommodations but for a younger man fighting cancer, nothing. We have a contractor friend that will do it for a significantly reduced cost but being that I am the only one now working that is even too much for our budget. We need help again. Today he was alone and needed the walk in shower that we don’t have while I was at work. Luckily, this time he didn’t fall. Falls with his bone metastasis are bad. We need to avoid them
