Interior room in the book Yakovlev.
The walls are blue. Under a ceiling painted with ships and flowers. Near the door we can see in the picture iron plate, which makes the growth of children. Some windows were chests, which were towels and other things for water treatment. In the photo you can see a wide door. It is WC which was made as a closet. Inside Othman drawings. On the table was set for irrigation watering princesses. On the table were fruit girls after bath.
I think we will never see a bath, because then it was dark for photos. Therefore, we can not see the Empress bath too.
