This was Bob's cell at the Polunsky Unit
The toilet and sink are combined into one unit and hang from a metal wall in the corner of the cell.
Light comes through a metal screen in the wall just above the sink.
Natural light comes into the cell through the long thin window.
The door is metal and has a “bean slot” where trays are passed and the inmate puts his hands through to be handcuffed before leaving the cell.
The windows in the door have a screen in them rather then Plexiglas allowing for better ventilation and making it easier for inmates to talk from cell to cell or from cell to the indoor recreation area the cells face.
