Disadvantages of Squat Toilets

A common argument against the squat toilet is that if toilet paper is used where there is no flushing system installed, it is easy for the inexperienced user to clog the toilet. Those unfamiliar with the squat toilet should be sure to ask the location of the flushing bucket before attempting use. These buckets flush the toilets manually like a tank would.
Other criticisms include:
1. Difficulty of use for the physically handicapped or inebriated.
2. Potential for splattering of urine or feces on the feet.
3. Potential for urine or fecal accidents with the clothes. People who are not used to squat toilets (i.e. residents of first- world nations) usually remove their pants and underwear completely before going.
4. Potential for leg cramps, or discomfort for users having osteoarthritis.
5. Potential for the development of foul odors as a result of incomplete flushing.
6. Pantyhose must be lowered while using a squat toilet.
7. Many countries where squat toilets are the norm are hot, so most people wear flip-flops, and the user's feet often become wet from the puddles of water around the toilet.
8. Squat toilets often lead to constipation for those who have not used it before and the faeces don't leave the rectum.
