Toto bathtub - need help quick

Anyone dealt with this before? I purchased a toto airjet 60 inch tub that is a mere 33 inches at the base, not enough to sit in with legs extended. Who would manufacture a tub that you can not sit in without bending your knees? I am short so that is not the problem. When you look at the specs it doesn't show this measurement. It shows 48 inches, however that was not for the base, very deceiving. Any advise on what to do now? The tub is too short to be used in my bathroom and to try to sell it on Craigslist will be impossible since I can't fit in it, other than a child no adult will fit.
