It depends. The simple ones are drums that are like daylight tanks
for stainless steel reels, they have a light trap at the fill end
that does not depend upon a reel.

You stuff the print in it in the dark, close it up and and develop.
Simple drums get rolled on the table, more complex systems have
rolling machines.

Normally they are used for color because consistent agitation and
temperature control are necessary.

There are all sorts of drums for the rolling machines including one
that holds sheet film in an interrupted spiral. You would use it for
small prints if you want to develop several at a time.

Look up Jobo.

Since the steps after printing can be done in daylight with no special
equipment, you may not want to use the drum for them.

Ok, at what step can I switch to daylight equipment? Do I have to stop
and fix a little before switching to daylight? Or can I do the stop and
fix in daylight?

Thanks,

No, you do the stop and fix in the dark and switch to daylight
for rinse (first wash), hypo clear and wash.

Thanks. I'll have to start putting a list together and approximate cost
to put this all together.

_____
My first darkroom in Vancouver, Canada was the same; a windowless
bathroom. I would place two rubber padded 2x4s on the bathtub, and put
the enlarger on it. The trays (11x14 was biggest size i could do) would
sit on the counter by the sink. To do exposures i would sit on the
toilet lid facing the bathtub/enlarger. I second the idea of using a
drum plus motor base. You can easily make your own drum(s) from 4 inch
black drain pipe and develop/stop/fix/wash prints that way. Use a large
O-ring in the center of the drum to stop it from rolling itself off the
base.
