I am getting rid of my old cast-iron tub and want to replace it with a traditional tub/shower with glass doors. What are my options? I've seen one-piece tub/shower enclosures that are affordable ($299-$400), but I'm concerned about the quality. I want it to last for a long time and for it to still look nice when I sell my home in 5-7 years. Also, what kinds of materials are used in tubs? I've heard of steel and acrylic. Again, I'm looking for good quality and value. I don't want a cheap solution that will need to be replaced in 5 years. I don't mind spending a little more for a better product, but I can't go crazy. We are doing a mid-priced bathroom remodel, not luxury.
As you can see I am completely clueless. Thanks for any advice!
