A woman went to the toilet at Chinatown MRT station on June 20, and was taken aback by its unhygienic state.
Stomper JK shared photos taken at about 5.45pm with Stomp, depicting unflushed toilets, cubicles littered with paper, and bins overflowing with trash.
"The floor was still littered with toilet tissues as of yesterday," JK said. "The toilets are dirty, period."
The Stomper added that since Chinatown is a tourist attraction, the traffic flow to the toilets is high.
"It is a shame to see the filth daily."
In response to a Stomp query, SBS Transit spokesperson Mrs Grace Wu said: "SBS Transit is committed to providing comfortable and pleasant travel experiences for our commuters - and this includes maintaining the cleanliness of our trains, stations, and facilities such as toilets.
"At Chinatown station on the North East Line, the toilets are cleaned daily - about every three hours on average.
"On Friday, June 20, a scheduled cleaning session was carried out at 5pm. Regrettably, the toilet was dirtied within the hour, as reflected in the photographs.
"While we are reviewing additional measures to improve cleanliness, we also appeal to users to be considerate and responsible. Everyone plays a part in keeping shared spaces, such as toilets, clean and comfortable for others."
