I have a six year old sulcata, about 40 lbs. I live in Michigan, and my tortoise lives indoors during the winter months. I'm not sure the best way to handle soaking him. We used the bathtub last year, but it clogged up the drain badly, was hard to clean, and kind of gross. This year we're considering soaking him in a large storage bin, but I'm wondering what method you guys use to clean the bins after soaking? Obviously the bin of water will be heavy, and I can't go lugging it outside to dump it out (I am a petite woman). Since he usually defecates while he soaks, what is the best way to clean the bin each time? (Or what do you do that will work better?!)
