The Polish hotels and shopping centres may open again on May 4, the government has determined there.
The schools are being considered for reopening two days later, Prime Minister Mateusz Morawiecki said on Wednesday.
It is not the first relaxation of measures against the spread of the new coronavirus in Poland.
Parks and forests were reopened earlier this month, and more people were allowed to be in shops at the same time.
The number of Poles diagnosed with the new coronavirus stood at 12,415 on Wednesday.
606 Poles with the lung virus had died until then.
