There isn't that much in the darkroom that needs to be permanent. I suppose if your MF enlarger is really big it could be a pain to move all the time.
I'm also setting up a darkroom for the first time since the early '80s. Hopefully I can do the first test rolls and prints today (probably old negs for printing today as the test rolls will need to dry for a while).
Tough to get some chemicals out here in the 'wilds west of Toronto' though. I could only find Ilfostop bath at Henrys in Cambridge and I bought all 2 bottles so don't try there yourself!
