I would also put a second protective bag over the cushioned pool noodle toilet seat to catch splatters (yuck.) An easy, DIY, camping / emergency preparedness toilet that's also good for those long-distance vacation road trips!
you take a bucket, a section of pool noodle, a trash bag DIY Homemade Porta Potty. make your own potty bucket liner with trashbag, slip the slit pool noodle over the edge for a toilet seat and attach a roll of TP to the metal handle.
Glamping porta potty / outhouse - there's nothing like having a few of the conveniences of home in a potty tent. Brilliant idea for when you have to go in the middle of the night and don't want to walk to the bath house.
