Hi ! The contractor I hired to do the masonry work has just finished my "next new darkroom" ! So now I face the equipment construction problem (and have all the stuff I own fit inside...) The major problem is that the only place I have for the sink is a corner of the room.... one side is 1m90 cm (5 3/4 feet) and the other is 1m 70 cm (5 feet) long. but, if I've a good idea on how to build a rectangular plywood sink, I suspect my case to be a builder's nightmare.... So any help will be greatly appreciated ! Plans, pictures, construction details, all will help ! TIA ! P.S. I own a set of books on the subject : The Kodak "building a home darkroom", "The darkroom handbook" by Dennis Curtin and Joe DeMaio, and "build your own home darkroom" by Lista Duren and Will McDonald.
