Mend or fix? Priority or project?

Even if I have already started with changes to the kitchen in some major way it doesn't take priority over any fixes that may come up in need. Take for instance my major bathroom just started to adjust it's self. The tile between the tub and the wall are separating. Where it meets is about 1/4" to as much as a 1-1/2" gap between the top of the tub and where it is supposed to meet with the wall tile. As a quick measure we bought some ready made product to fit in the gap. Just temporary, but I still have not installed it yet. We had 15 people over for a week during my St. Nicholas Feastday and it is still needing attention. So my focus needs to switch gears to that bathroom. Money is spent already, so I might as well do the deed. I need to clean it up some more with borax and vinegar and now bleach to kill any mold or bacteria. My hold up now is that the configuration of the tub and fixing job is torture on my back. Not that Pop's back is any better, we are taking about my back right now. So, I need to review the situation before I attempt the job myself. This is what it is all about anyway. Figuring how to accomplish this task with my labor and limitations or abilities lacking funds to hire some able person to do what I need to have done. There, now that I have said it. I can focus on how to go about doing this fix job. It may take a few days to think this through and not hurt my muscles. I shall view the web for some examples for a day or so. I need to target this weekend to do this job I think. Seeing as I spent yesterday cleaning up my art studio floor that always leads to clearing the table. That leads to organizing the glass beads of course! Smile, it was a day off of work and one should mix play with pain, yes?
