I found that most toilets in Hong Kong has a WC seat sanitizer inside each toilet cubicle for you to disinfect and clean the seat cover. Just spray a bit of the sanitizer onto the toilet paper and then wipe the seat cover before you use. Simple and convenient.
Isnt this a very good and hygienic idea for Singapore to follow as well? Cost wise, I believe its not that costly to install and maintain. I think this is much better than those types of fanciful WC seat covers with toiletpaper-roll type for you to seat on.
