A tower devoted to a restroom? Doubt it —The preceding unsigned comment was added by Colin687 (talk • contribs) 03:59, November 19, 2012 (UTC).
The name of this article is clearly meant in the indicative sense rather than the possessive. It's the difference between "my nose" which is exclusively mine forever, and "my table" when eating out at a restaurant. And remember when posting to talk pages, to sign your post with four tildes (~~~~) (and to give your post a headline if it starts a new section) in future. — RobertATfm (talk) 14:51, November 19, 2012 (UTC)
This is maybe nitpicking, but shouldn't it be just "Lavatory tower" because in the Half-Blood Prince video game the boys lavatory replaces Myrtles bathroom? That fact could indicate that in canon both lavatories of Girls and Boys are in the same tower? Mieguy (talk) 19:51, July 8, 2015 (UTC)
