Hi I had a home birth last friday and used birth in a box which is now in our garden and works brilliantly - along with the standard extras we also bought an electric pump and electric water pump and is our best buy so far - we have been enjoying beers in the pool in the garden and midwife says we can take our little baby boy in with us when the cord has dropped off. thoroughly recommend home birth by the way.
The reason I went for it over la Bassine was that it has handles on the outside. From previous birth experience, I expect I'll find them handy to lean over the side and hold onto during the pushing bit.
We had a go at inflating it a few nights ago and the mini seems a good size. Not filled it yet.
We hired a pool from Aquabirths. Very friendly, they deliver and assemble as hard sided. Very big and would recommend excellent service. I was 14 days overdue and no hassle about getting the pool back.
I had a la bassine and couldn't fault it. I'm not exactly small (5' 8" and 16 stone) and it was lovely and comfy for me. Invest in a pump to pump OUT the water - lot quicker than waiting for it to drain out of the hose via gravity or ladelling it out by the bucket full. We had an old fish pond pump which did the job. Just make sure if you're planning to use the pool before the actual birth date to run some Milton through the pump.
