Looks like lots of good advice here already.

Idk how handy you are, but tile/grout was not nearly as hard to do as I expected. It just takes a long time to DIY this type of project. But it is immensely satisfying to answer "I did that" when someone compliments your finished work.

The only tool you might need that is not something most homeowners have is a wet saw. I bought a cheap one for almost the same price as renting a nice one for a weekend. And it has helped me do two bathrooms and soon my kitchen.
