Definitely shower. I like bath only when I'm doing it for relaxation and quiet. I never take a bath just for the purpose of becoming clean, I'm with you Sahm, how do you get clean when in dirty bath water. yuk!
Shower...unless I'm soaking to ease the tired muscles. I'm not too concerned about hot tubs. I used the one (when living on Hilton Head Island) all the time. But I think the thing was highly doused with chemicals as I smelled like Clorox and it dried my skin out. The warm sulphur springs in Colorado are da bomb!
oh..and I pretty much don't like giving them to my kids either. We recently replaced the shower head in our bathroom so that it is a removable spray type..and now the kids get a very quick scrub down so mommy isn't spending 2 hours doing baths. Takes us about 20 minutes now..with scrub down, towel-dry, lotion, combing out and blow-drying the hair! Much easier!..and much better on my back!
