Shower over tub - hardware components
I'm planning a hall bath remodel. Keeping existing walls, but all new everything. I'm trying to zero in on cost of parts (supplied by me), but I'm having a hard time understanding all the components I'll need in the shower, since it seems a lot of them are sold separately.
I will have a shower over tub. So, I need a place for the water to fill the tub and something that turns the water on and controls the temperature and diverts the water either to the shower or the tub. Duh, right?
I would prefer to go with simply a handheld shower on a bar and no fixed shower head. However, this is a guest bath and not a spa. I don't need to go overboard, so if the whole handheld sprayer gets too expensive, I'll get a fixed head.
What about trim? What's an elbow?
What individual components do I need? I really don't want to spend $1K on this part of the bathroom. $500 is more like it.
