It’s extra long, fits the bottom of the entire tub with a portion custom cut out for drain. I bought the clear mat and we love it. I read in one of the reviews prior to my purchase that after showering, the person picked up the mat from the floor of the tub, rinsed it off with the shower head and stuck it (suction cups work well) to the shower wall, out of the way yet handy for the next use. That’s what we do and it’s ideal.
