No, the room doesn't freeze, thankfully! As for the chemicals, sometimes it's hard to bring them up to above 15°C. I'll look those up! Thanks!Presuming the room itself doesn't freeze between sessions, you can pick up a sous vide for as little as about $40 on eBay. Run a tub full of cold water, put your chemical bottles in, and start the sous vide -- go get a cup of coffee or hot cocoa, come back, and your chemicals will be ready to use. It's a compact, fairly lightweight device, smaller than a 2 liter bottle, so easy enough to bring with you or store in a locker if you keep your stuff there.
The water/ambient temperature is cold enough to keep the chemicals at about 15°C, so yes, bringing my electric kettle would be a good idea this winter...I'm in the Paris region, btw. Thank you!Where are you located? Does the water run really cold in the winter? I have used an electric kettle to heat up water and then immerse the chemical in beakers (like a bain-marie) to bring them up to 20º. You can do this for film or prints. I will usually use a large metal steam-tray pan for this so I can warm all the solutions to temperature at the same time.
