Dark Room Sinks
Original dark room sinks are made from Polyvinyl Chloride PVC thermoplastic plate and pipe. They are custom designed to handle the chemicals used for photo development. Pricing varies depending on the quality you want as well as any additional features you want to have added to the sink. Most come with some type of warranty.
You can make your own dark room sink if you can’t afford to purchase one, or if you just want it designed to your own specifications. You will need PVC that is 1/8 of an inch thick. It comes in large sheets, but can easily be cut to any size using an electric saw. It cuts very easily. You will need a piece of plywood to glue the PVC to. PVC pipe cement, PVC pipe primer to soften the PVC before gluing, PVC cleaner to remove grease, a large piece of wood for the sides and back, and a 2×4 to make legs. Use a regular plastic kitchen drain and be sure to waterproof the surface of the wood so it will last a long time.
Another option is to simply use a sink or even your bathtub to develop your film. It is important that you make sure they are clean of all soaps and dust prior to using. It is possible the soap can react with the chemical process, damaging your negatives and prints. Whatever method you choose, have a great time creating your photos!
