Try the Darkroom Cookbook or the Film developing Cookbook both I believe
have sections on Darkroom layout.

One tip: do NOT use black material, especially plastic, to cover the windows
on the sun-side (South in NA). I did and it acted as a terrific solar panel
and overheated the room even in 10F weather, and finally one day it got so
hot it sagged and leaked light. I finally used a highly reflective 'space
blanket' towards the outside, and lightproof material towards the inside.

If plumbing is a problem because you don't want to make expensive, permanent
plumbing changes then a hoses from the existing lines, then an electric pump
in a  big bucket under the sink will work for a drain, but I'd never leave
it unattended.

I have successfully used aluminum foil in the past, secured in position with
black duct tape.  Definately opaque and dirt cheap.  Extra heavy gray plastic
from the local home improvement store also works well.  I used some stuff that
was, as I recall, 6 mills thick; two layers worked very well.  Plastic is more
expensive than foil but the neighbors aren't as likely to look at you oddly
after you put it up...  :)

I'm using the kitchen. We have huge windows, and yes they get plenty o
sun. But I just created a black plastic sheet using two extra thick yar
cleanup trach bags. I taped them together using gaffer tape. It neede
double thickness as light came right through the bags on a sunny day.

At Staples I found a roll of velcro with a glue backing - using thi
enables me to quickly put the sheets up, and in between exposures I ri
them open - this cools the room and also lets in fresh air.

The whole setup cost about $30 and took a couple of hours to make.
also cover the doors.

So far the neighbours haven't thought I'm growing weed and haven'
called the cops on me, so I guess that's positive
