I remember asking the midwife on a hospital tour at my private hosp could I have a water birth in their baths. She said no as the baths aren't set up for it (as in only one side of the bath accessible to the midwife) however, she said if you don't call us till your giving birth in the bath then thats where you will have your baby - and a few babies have been born in the baths there as thats what happened!!
