Recently moved and can’t have a bathroom dedicated to film processing. Don’t want to get anyone exposed to the chemicals when they shower. Was planning to line the tub with a shower curtain and punch out a hole for the drain when I process. Any thoughts?

I guess you're shooting LF film if you need a bathtub. Sure, something like a shower curtain would work fine (keep in mind the weight of 8 lbs per gallon of fluid), The best developing trays I've used were made from cut down cardboard boxes. I placed some heavy duty, black plastic liner into the trimmed boxes and duct taped it on the bottom. Worked great for 11x14 prints.

What chemicals are you planning on using? I'm assuming no pyro developers, or toners.
If you are using standard black and white chemicals to develop and print, just clean the tub and surround before and after darkroom use.
The cleaners you use to maintain and clean the tub and surround are probably of greater concern than the darkroom chemicals.
I nest the trays I use in larger trays to minimize spillage, but that is mostly done to make cleanup quick.
A hand-held shower spray also makes it easier.
This will give you a sense of what I do for printing - the top 11x14 inside 12x16 tray is the fixer tray - the stop bath and developer trays are to the right on the top shelf.
The two wash trays - one draining into the other - are below:

Rather than line the tub, you could make a small 'sink' out of 1/4" ply, and paint its interior with marine varnish or polyuretane varnish (much more durable and chemical resistant), then lift it out of the tub to pour down the toilet any fluids that escaped the trays. Screw-in base for legs would permit this shallow tray/sink to be at proper height for comfortable work.

I like Matt's arrangement for wash tray!

I made a table to fit over the tub while I was living in an apartment, and my Jobo processor sat on the table for use.

I thought since this thread is in the color forum, he might need to use the tub for water jackets or something. Why would anyone developing black and white film need to use the tub?

For black and white film, I only use the tub area to hang my film to dry :smile:

Spray down your work area with the shower head after you're done processing film. I wouldn't complicate matters unnecessarily.
Otherwise, I'd suggest getting a big tub or tray that fits within your bath tub in which you can put all your tanks, trays, beakers etc.
The shower curtain solution sounds messy, hit and miss, laborious and altogether awkward.

That makes sense. I do black and white but also a good bit of color. I only develop film right now but plan to print in the future.

Don’t think of this at all. Will make clean up easier and saves my back and knees when I need to spend a lot of time in there.

I use a folding ironing board and/or empty plastic tubs sitting on wire shelving for this purpose.

Yikes, I'm sure glad I survived that phase. Just don't use the cable series, "Breaking Bad", as procedural instruction for how to use a bathtub.
