Is $1,600 to repaint two bathtubs a fair price?

I have a rental unit where both the bathtubs have started peeling. I bought this approximately 4 years ago and it's been rented for 2 years now. I think they did bare minimum renovation at that time and the quality was not good to start with. I am worried about not doing the repaint myself because I have never done it and don't want to do bad work. I will take care of other small tasks at home. I am wondering if a complete repaint is required or if a repair would work. I also thought of getting the tub replaced instead of repainted and am wondering if the rough estimate for replacement is too high and what a good price would be.
