i am in the same situation as you and i just bath DD with me in the bath. I find it the easiest way to go about things and she loves it! Logistics are that i get undressed first then her and then the bath then we gat out i wrap her in a towel and put a bath robe on me and dress her then dress me. It just works best for us

I do have the thing thay Kim and RRaver were talking about but only use it when i'm not getting in the bath with DD.
