Smallish blow-up/metal frame pools advice

[midcenturylegs]

Hi - really not sure if I'm posting in the right place - please let me know if I'm not.

Looking to buy a small rectangular pop-up/temp pool that's deep enough for my 12 yr old DD to swim under in - perhaps 60cm depth. I've a small (and shared) garden and it'd have to go on a slightly raised decking which is 180cm width (the decking is quite long so no real length issues). There are a few ones about that size with a metal frame but you need to add an extra foot each side for the frame legs. Something like this, but narrower. www.amazon.co.uk/Intex-Rectangular-Metal-Swimming-Paddling/dp/B008OWBAEQ/ref=sr_1_5?s=gateway&keywords=Intex+Metal+Frame+Rectangular+Pool&tag=mumsnetforu03-21&qid=1561730181&sr=8-5

Can anyone advise on something? Reluctant to put it on the grassy area as it'll kill the grass (which in places is long as I've wildflowers growing).

Any advice welcomed!

@midcenturylegsI'm just wondering whether you have any hints and tips re the pool a year further along?

We are hoping to rest ours on sand dug into a level ditch (if we can source sand) for now. DD is a keen swimmer (so she is going to be tethered swimming, we hope, as I can't see us being allowed in a public pool any time soon).
