Pol Col Phaipana Petchyen was moved to an inactive position at regional headquarters in Songkhla, effective immediately, under an order signed by Pol Maj Gen Weerasit Pethklai, deputy commander of Provincial Police Region 8.
A senior officer in Chachoengsao was transferred earlier for slopppy housekeeping.
The order said the chief in Sadao was negligent in his care for the workplace, letting the station and its toilets deteriorate and remain dirty with no signs of improvement.
As well, it said, he had failed to manage Rohingya migrants detained at the station and 30 subsequently fled. His superiors also said Pol Col Phaipana had failed to tackle oil smuggling from neighbouring Malaysia.
The station now is under responsibility of Pol Col Waiyawit Nopparat, the station's chief investigator.
Pol Col Phaipana was the second senior police officer punished by the Royal Thai Police on failing to improve stations after a colleague in Chachoengsao.
National police chief Adul Saengsingkaew on Oct 8 transferred Pol Col Sanan Boonphuen, the superintendent of Muang police station in the central province, to police headquarters in Bangkok.
The transfer order, made via police radio, followed a visit to the Chachoengsao station by deputy police chief Ek Angsananond.
Pol Gen Ek found that the operation was not in line with the cleanliness and tidiness policies set by the national police chief.
The deputy chief found graffiti on the walls in detention cells, while several other areas in the station were dirty.
The police chief has assigned Pol Maj Gen Cherdchai Sekanand, acting commander of Chachoengsao police, to evaluate why Pol Col Sanan failed to oversee the station properly.
The Chachoengsao station was quickly cleaned and repainted after the lightning transfer order.
Pol Gen Adul made clear when he took the top position a year ago that police stations must be clean since they are the places where members of the public first make contact with the force.
He said in a speech to subordinates at the time: "An untidy garden, a washed-out building, a filthy police station and a dejected superintendent - we can't let this go on."
