Water birth costs vary depending on whether your hospital or birthing center offers it. You may or may not be charged a fee for using their birthing pool.   On the other hand, buying your pool kit can cost you $250 or less. You can also rent a birthing pool through your midwife, and the charges will depend on her.  If you decide to get your water birth equipment, inform your insurance company about your plan as soon as possible since it may cover the cost.
