The Moslem religion demands that ablution should be performed five times a day, before each ritual prayer. There are washrooms and ablution closets within the house for this purpose. Each room, which is the basic living unit is provided with an area and facilities for the performance of total ablution; a well thought- out solution from the point of view of the intimacy of family life. Considering the close relation between the two, the toilet is generally combined with the wash-room.
As a consequence of traditions, water used for washing dishes is never mixed with the sewage. It is either collected in a separate pool or runs freely through a wooden gutter into the garden. No specific space has been allocated for worship within the house. It is believed that the ritual prayers (namaz) can be performed anywhere that is clean enough.
