Just for the record there is a new wet darkroom on the block. It is 9 foot square and all painted black. Man, I can hardly see anything in there. The reason is because movie film will be printed, rolled out and so on; large format film will be loaded and this way, all black, less light will bounce around. There isn't ANY light that gets in there anyway! Course, you gotta be in Pgh PA to visit it. This one is being used. Two others are nearby but they are inert. Too old. Too late. Not available for use. A salesman at B&H said of my comment, mine will be the last darkroom made, "Well, maybe the NEXT to the last one."
When you gonna make yours? Why don't you list it here.
