Bathtub Replacement
 

How easy is bathtub replacement? Is it something that would take a short time, or a whole weekend? Would you recommend total replacement or one of those 'bath fitter' options that just goes over the existing tub?

What kind of tub is that? A clawfoot or built into a concrete base? If it's a clawfoot or similar, it's only a matter of disengaging plumbing and drainage and getting the tub out of there. If it's built-in, it won't be as simple. At least, if you're considering it as a DIY job, have somebody experienced take a look and draft a rough plan for you.

The bath fitter option is quicker and cheaper, but doesn't last as long. This is probably one thing I'd go to the pros on, but that may just be because I have a fear of plumbing!

I have tubs that are blue and mauve. We are going to refinish them white instead of replacing them because they are steel tubs and they are huge which aren't being made anymore.

This all depends on whether you have water damage on your tub walls. If so, then total replacement make sense. If not, bath fitter option can be considered.

Normally, it will take the professionals 2-3 days to gut and install the entire tub area (tub, faucet, walls). This is pretty involved since you are pretty much dealing with demolition, plumbing, boarding, tiling, and possibly a little taping. Also, you need to know suitable products and materials to give you the best value and quality to meet your budget. So, if you are not prepared for this kind of challenge, leave this kind of project to the Pro.

The bath fitter option I personally do not recommend it. There are actual cases that water leaks in between the tub liner and the old tub, and the tub bottom becomes very bouncy - the famous "water bed effect".
