"Willie didn't like the idea that there was going to be a female in the house on a regular basis because it meant he and Barnabas could no longer make cookies with their EZ Bake oven without embarrassment."
I know some fans love to make fun that the Old House had an outhouse. However, I can't go one more second without pointing out that (and this isn't directed at any one fan in particular because several have been guilty ): The flush toilet was invented in 1596 by John Harrington First valve-type flush toilet was introduced in 1738 by a man named J.F. Brondel (J.F. Bronde) Alexander Cummings invented the Strap, a sliding valve between the bowl and the trap in 1775. Samuel Prosser applied for and received a patent for a plunger toilet in 1777. Joseph Bramah altered the design in 1778 so that it had a valve at the bottom of the bowl that worked on a hinge, a predecessor to the modern ballcock.And something tells me the Collinses were rich enough to have had the latest toilets installed in the Old House when it was constructed in 1767 - and the facilities were probably upgraded with each new innovation (Revolutionary War be damned!). The idea of Joshua Collins - or any members of that generation of the family, for that matter - actually using an outhouse is patently absurd! I suspect they would rather have been dead.
Ah, but you see the Collinses didn't need a sewage system or plumbing. In well-to-do 18th century homes, it was often customary for toilets to be located in rooms outside the main structure of the house but connected to and still a part of it with no need to actually leave the house to access them. (How was the waste disposed of without a sewage system or plumbing? Well, we won't go into that here - but it's easily discovered via a Google search. ) And despite Collinsport being a backwater, the Collinses themselves were extremely well-to-do - ergo... The Collinses laughed at the mere mortals who had to use outhouses!
What you're describing sounds like an outhouse to me.
When I did research for a story, I found no evidence of a remarkable modern toilet being installed anywhere in what was to become the state of Maine, let alone anywhere else in the country. Besides which, the "u" bend wasn't invented till the mid 1800's so, if Joshua had installed anything like a toilet (as it existed in 1767, or even 1795), anywhere near or attached to his house, the smell of sewage would have backed right into his house and grossed everyone out. What record about well-to-do houses have you come across that had working toilets attached to the house like you describe? Because boy, that would certainly change some of my research.George Washington had an outhouse. So did Thomas Jefferson, and he was a guy who liked things to be modernized, so I don't think it was customary for anyone to have a toilet. www.victoriancrapper.com states that "In fact, until iron foundries improved cast iron pipe and potteries improved terra cotta pipe in the 1800's, if there had been a functioning toilet, it would have been placed in the outhouse anyway." (Which makes it an outhouse, not an indoor toilet.)
