One of the best things about my midwife's birth suite was the large soft tub. I'd never heard of a soft tub before but it was amazing, nice and comfy. It's soft because instead of a porcelain tub, it uses a sand-filled base. Plus she had a tankless water heater so there was never-ending hot water. I spent most of my time in that tub. Makes me want to get one like it for myself.
