Extra Long Shower Curtain Liner Anyone Know Where I Can Find An Extra Long Shower Liner?

Anyone know where I can find an extra long shower liner? - extra long shower curtain liner

I shower in the bathroom, no tub. I have a fairly long shower curtain, but the shirt is too short. It measures 82 cm long x 42 cm wide. I know it's an odd size, because I looked everywhere online not. Perhaps you have any suggestions? Thank you!
