Re: redoing tub and shower
No, you do not need to have both, however in a single bathroom home (1/2 bath doesn't count ... ) a tub may be more desirable for resale value. Incorporating a shower into the tub is a nice way to have both. Having a shower only will not save you any space as far as that long wall in the bathroom. By the time you put in a usable sized shower pan (36" x 36" minimum ), there isn't really any usable space left.
