I read the reviews before purchasing this rug.  It did come 1" narrower then the 20"s stated but it was spot on with the 4'11".  It didn't matter to me and fit perfectly in my new neutral tone bathroom that I needed a splash of color to spice it up.  As you see it fit between toilet and outside wall right next to the shower stall. (3.5 x 5.5 space) It's red and off white to me and I loved the $19.99 price tag.  With red towels, I'm happy.
