Ideas on how to fill something, make it a pool lol

I can get a tarp and a water hose but we’re not allowed to use our water spikits outside thanks to my son (long story)🤦🏻‍♀️🤦🏻‍♀️

So my plan is to hook up a water hose to my sink and fill something up with water, just until my next paycheck when I can buy a kiddy pool lol

Any ideas on what I can use?

I don’t have a truck so not the back of a truck lol

Y’all I’m so desperate I might just use one of these huge ass storage container just so I can soak up the water and sun outside lmao
