First, I am a beginner. I have a homework where I have to design a staff area.


How can I make small drains in public washroom?

How can i make cracks at toilet doors just like the ones in the mall?

How can I raise the floor little bit to separate ablution area and prayer area?


For drains, I tried to use sunken ground but I wonder how can I put a cover on it... And did I do it right to use sunken ground?
