A few years ago, I photographed a home birth where the mama gave birth in a huge, heated birth pool. Like this: http://www.birthworks.co.uk/octagonal-birth-pool.php

Since then, I've been looking for a place in the U.S. where I can rent a pool like this (heated, padded, sturdy sides), and I'm finding nothing.

Anyone else?

If you used an inflatable pool, did you find it hard to keep the water warm? Any tips?
