A “shithouse,” is an outhouse used for urinating and defecating. These buildings, used before indoor plumbing was common. An outhouse built out of brick, therefore, would be one that was much more well-built than usual, hence the allusion in the idiom. The expression is rarely heard today probably because of social mores and it’s offensive vulgarity, but it originated as early as the 1930’s and was quite common until the 1950’s.
