I got one of the hexagonal ones for my first labour (from Birthworks: https://www.birthworks.co.uk/hexagonal-birth-pool.php ), as I was worried about our cat and an inflatable one! He scratches everything and the only place I had for a pool in my last flat was the living room, and I couldn't easily keep him out of there.
I posted a bit about hiring it and setting it up on the Home Birthers and Hopefuls thread last year. There are some photos:

I didn't actually get to use it for the birth as I got transferred to hospital due to meconium in my waters, but as it was set up for a fortnight in advance I got plenty of use out of it. I listened to music, watched TV and listened to my hypnobirthing relaxations while in it and it was brilliantly relaxing. So I felt I got my money's worth!
It was great in my early labour too, before I got transferred. And it was big enough for my husband to get in with me too. Essentially you have a hot tub in your house.
This time I have gone for an inflatable La Bassine as I have enough room in my bedroom for it at our new flat, and can keep the cat out.
I also didn't want a filled pool up with my little boy around, as the hexagonal one I hired previously didn't come with a rigid lockable lid, just some polystyrene to float on top to retain a bit of heat. I would be panicking about him getting in it if it was set up for a couple of weeks.
I haven't fully tried out the Bassine yet, but we have inflated it and I sat inside it while it was empty. It seems very good, the floor is well padded and even without the buoyancy of the water I felt very comfortable. The sides also seem good and firm to lean on. It has less handles than the Birth Pool in the Box, but they seem well positioned. It came in a kit that Made in Water do with air pump, water pump, digital thermometer, lid, liner, debris net, and tarpaulin.
Hope that helps.
