Oh Boston Diner!!!! We were definitely raised similarly w/r/t baths. We didn't have a shower when I was a kid, and I was also in a household where you got (at most) about 2 inches of water, got in while it was still somewhat warm, got as clean as you could, and out you came.
When I was older I sometimes emptied the tub, allowed myself another 2 inches, and tried to rinse properly and remove the residual grunge I always felt was still there.
I never could understand how anyone liked to 'soak' in bubble bath - purely a function of never having had the experience, and possible my loss, but too old to change now.

For the past 50 or so years I can count the times I've had a bath on one hand. Just prefer a shower. DH, on the other hand, loves the occasional soak (after a shower) and fills the tub to almost overflowing. He also complains that our *modern* bathtub isn't deep enough, and would love an old-fashioned high sided one, which I do NOT like at all.
