If it is a permanent tattoo, then it would last on the bottom of your toe forever. If it's a temporary tattoo, it would probably only last a day or two.
2-3 weeks. Once all the scabbing is off, itching has stopped, you can tell that tattoo is healed and you see the new skin then you are fine to go swimming. Realistically speaking it takes about 3 months for a tattoo to fully heal but I haven't had any problems as long as I waited at least two weeks. With my last tattoo, it took longer to heal and it was about a month before I could go swimming. For this reason I usually only get tattoos in the off-season.
