In this mosque, the pink tiles are used for the decorations, for this reason it is also called the Pink Mosque of Iran. The main entrance to the mosque is made of seven color tiles with many Shiraz iris decorations.

This mosque has two Iwans: the North Iwan, which was built with a height of eight meters, and the South Iwan, which has no special use, were created for symmetry with the North Iwan.

The mosque has two naves, one in the west and the other in the east. The eastern nave is a winter nave facing the qibla, and it should also be used in very hot summer weather, which is designed to prevent direct sunlight and warm the nave.

The western nave is one of the most beautiful mosque naves in Iran, which was decorated in tiles and bricks with paintings of roses, but repairs were made to it around 70 years ago, which covered the turquoise tiles. . The columns of the Nasir Al-Molk Mosque are one of the most beautiful columns in the historical places of Shiraz.
