I did a post about my hired rigid sided pool from Birthworks here:
Rigid Pool Review on Home Birth Thread
it has some photos and info on putting up the pool etc. The few posts after that one have a bit more info as I respond to a few people's questions about it.
In general
Pros: You can leave it up all the time (for weeks) as it has a filter and comes with oxygenation tablets that you add each day, it is nice and solid, it is big (big enough for two people), you can set and maintain the temperature, not inflatable so good if you have pets who might pop an inflatable one.
Cons: It is expensive, it is big so you need plenty of room (our large bay window was perfect), it can make the room a bit more humid than normal, you are paying for the electricity to run the filter and heater, there is no solid cover so you would have to watch older children around it.
I loved it.
In the end I didn't get a homebirth but I felt like I got my money's worth out of the pool as I had been using to relax each evening for the previous 3 weeks of the hire. That was a great thing to have, the feeling of floating is lovely in late pregnancy, and MrUrban got use of it too which he enjoyed.
I was in hospital when it got taken down so I can't say much about packing it away but my husband says it was easy. It came with a long hose to fill it and a pump to empty it (also a thermometer, jug, step, floating cover, sieve, spare filter, spa treatment tablets and liquid, plastic step stool) and he said the pump was quite quick to empty it,and then he bunged our dehumidifier on to dry out the liner. It disassembled pretty quickly too. We just contacted the hire company when we were done with it and they arranged the courier to pick it up on our day of choice.
Hope that helps anyone wondering about hiring a rigid sided pool!
