I have an end ileo and this method worked for me when I had a temp ileo as well. I have a crockpot that I use. You may have to experience with different buckets and basins. A crockpot works for me. I lay down on my back and put the crockpot on my right side where my ostomy is and I put my ostomy bag in the crockpot and I let it drain all night in the crockpot! It works for me.
Hope this works for you! Happy New Year
