Wet side of the darkroom.


On this side of the room you will have laid out your developing dishes in the following order: developer, stop-bath, fix, print washer and/or sink. These may have heaters under them or you can have a slotty laid out in the same way. Obviously this will take up less space.
Typical wet side layout


This is where you keep your chemicals, it is also the place that the solutions are poured out and back into their storage containers. The height of this table needs to be right so you can work comfortably in the standing position. It is a good idea to store these chemicals under the table if there is a leak it will go on the floor and not drip into your working dishes ruining your prints. For safety reasons it is not a good idea to lean over your dishes to retrieve items from shelves above while your working as you may knock the contents of the dishes over yourself.

Remember that these chemicals need to be treated with care and you should follow the safety advice recommended by the manufacturer.
