Indoor plumbing is an undervalued commodity. 
A thing that is common is often undervalued. It is like the story that King Lear is based on where the daughter tells her father that she loves him the way salt loves meat and he thinks it means nothing while his other daughters lavish him with false praise.
In the stories not as melodramatic as Lear, eventually he is served meat that is unsalted by his daughter who, having been disowned, has become a servant. Then he cries tears because he finally understand just how deep her love in. In all the other stories but Lear, they are reunited and live happily ever after. But Lear, being a Shakespearian tragedy, everyone dies. Hope that isn't a spoiler for anybody

That's pretty much how all his tragedies end.
But yes, indoor plumbing is a great, great blessing as anyone who has ever had to use an outhouse, especially in the middle of winter can attest. I can't but when I was younger my older relatives told us stories about it.
