Today I went downstairs and noticed that the bathroom down there had a
horrible smell. Like a sewage smell. We dont use the bathroom as we
noticed a year ago that the toliet leaked and the basment isn't
finished. We have been dumping the dehumidifer water down the sink
drain.
What could be causing this smell????

If there is a tub, the trap may have dried out. I don't use my tub opting
to shower in the basement and I have to run water in the tub occasionally
to refill the trap.

I just put duct tape over a shower I never use. Alternately RV antifreeze

If all ideas of dry traps fail the toilet wax ring is bad
