I bought an AquaBorn Eco Birth Pool from YourWaterBirth.com. Unfortunately I was unable to birth in it, but I did labor in it...AmAzInG
I labored at home for 16 hours and getting in that tub was glorious. I got in and out 3x while at home because I was relaxing a little too much. Ctx were same intensity, but 1-1.5m apart on land and would slow down to 3+m in the tub. I didn't have a thermometer, just went with what felt comfortable, and we kept two big pots on the stove to replenish warm water. Also, these tubs come with a liner and you can purchase extra. I highly doubt I will be sharing this tub (esp. since I haven't even used it to it's fullest potential yet btw I've read you can get 5-6 uses out of a personal birth pool with proper care/storage), so I didn't bother using the liner. I inflated it with some pump that came with an air mattress and I just did some quick swipes with the steam cleaner and rag. I did not buy a new hose or adapter. I took a fairly new garden hose that had only been used in the house and followed these instructions for disinfecting it (step 9: I ran really hot water through it for like 30 minutes to rinse): http://www.ehow.com/how_7506115_disinfect-old-water-hose.html
I ended up delivering in a hospital strapped down to a bed for the duration of labor and pushing . Never Again! I was even screaming, "I don't want to do it like this! How can I push if I can't breathe! I'm gonna puke!" -lol- It's hard to labor lying down confined to a bed when you know what it can be like, i.e. walking around, swaying hips (which you can so do in this tub, it even has handle bars inside), all fours (and the walls are rigid enough to hang over), all while still having belly under water because it is so deep. I wasn't around for "clean-up", but my husband just used a utility pump and hose he had lying around to empty the tub straight out the patio door.
To achieve bouyancy in water and allow easy movement between positions, 21" of water depth is required.
No matter what you decide to birth in, it'll be awesome because it's in water! I can't wait to break mine out again for my first HWB! I'm sure this is an exciting time for you and your family! Congrats!!!
