Anyone know where to buy a pool liner for a 300 gallon birth tub?

[SunnyBabyIn2005]

My midwife says we need to get one, I am assuming they are expensive if I go to a pool supply store, does Wal Mart or anywhere carry these?

What about just using plastic from one of those big rolls of painter's plastic?
The roll I have on hand is 9 feet by 400 feet, and is 'polyethylene sheeting.' I guess it would depend on the shape/dimensions of your pool...

It comes in different thicknesses, and the thinnest probably wouldn't be strong enough. I think rolls run somewhere around $20.

good luck!
