Choices for new bathroom in C grade rental

[Curt Bixel]

I am planning the complete replacement of a bathroom in a C grade rental.  I am doing some shopping on the internet looking for choices that will make a good balance between cost, durability, and maintenance.  I have good luck finding tenants who do a reasonable job taking care of my properties, so I lean a toward solid, mid-grade rental type materials.  

For example, for a tub and surround system, I would be willing to pay in the $500 to $1000 range and would be looking probably for a 2 piece system that eliminates any caulk, in a basic white color, that screws directly to the studs and is thick enough that it will last a while.  It might be nice if it has a shelf or two, but simple is best.

For the flooring, I would go with good quality sheet vinyl.

I am hoping that someone has already done a lot of thinking about this and has some suggestions of what tub, surround, flooring, toilet, vanity, and sink would be good choices.  Again, I am not looking to go with the cheapest items available, but recognize that there is a limit to the price of items that should be installed in a rental property like this.
