Translation:The tree is between the house and the toilet
Awkward if it's the middle of the night and you've had too much to drink…
Would "choo" also translate as "outhouse" in this case? I'm assuming "bafu" refers to indoor plumbing, I just wondered if this would be the most natural way of referring to outdoor plumbing.
'Choo' = lavatory or latrine, so I'm not sure that outhouse would be strictly correct - outhouse could mean any building or construction (with a roof) outside of the main dwelling and may not even have any plumbing! A latrine is normally a hole in the ground (deep or shallow) which may be surrounded by a screen (no roof) of some sort for privacy... I think this is a good sentence because it has been 'localized' - there is often a tree between the house and the latrine!. 'bafu' could also mean a tin bath - no plumbing - filled up with debes of hot water!
I suppose bathrooms are subject to a lot of colloquialisms across cultures. It occurred to me after I wrote the above comment, that some regions do refer to an "outhouse" as the "toilet" while my region usually reserves "the toilet" for the commode itself.
