You can buy a new bathtub for $400, a new lavatory under $100, and a new toilet for $200. All decent, but not high end quality. Reglazing any of that would generally be more money, with poorer results. I have never personally had any good experiences with reglazing. It's merely painting the fixtures with an industrial type epoxy.

LWO is right to a point, but if the OP has to pay for labor to tear out and replace the tub, and then install new tile, that's a lot more than the cost of a $400 tub. I definitely agree with swapping out the toilet, though. And you can buy a decent whole new vanity for under $500.

I'm not a fan of re-glazing (no personal experience), but a white tub that may fail in a few years might beat an avocado tub if that's all the budget allows.

OP: what's your budget, and what are you working with? Perhaps we can suggest some budget-friendly ways to get you closer to your goal.

We had my mothers beat up old tub reglazed in order to sell the house. I can't say how long it will last, but it did look really great after it was done. Probably a lot depends on the type of cleaning products you use.
