My place of employment replaced all the toilets last year with new TOTO wall mounted ones. I do not know the model and frankly am not interested in getting down to floor level to find it.
On this newsgroup I have heard the praises of TOTO toilets sung and yet find them to be awful toilets, at least in their flushing coverage inside the bowl. Yes, they do deliver a strong flush but the water never touches the back side of the bowl and you are always greeted with someone else's leftovers when entering a stall.
Why would such a basic engineering necessity be ignored by the maker of supposed superior toilets?
