Are toilets renovated at Hogwarts?

Question

Bathrooms at Hogwarts have water closets and porcelain faucets, which are relatively modern inventions, considering Hogwarts was founded over 1000 years ago. Are the toilets magical, and upgrade themselves to modern standards, or have they been renovated (by house-elves, I suppose)? How often do the renovations happen?

Until quite recently witches and wizards just used to crap wherever they stood, then use magic to clean it up. #CanonFacts — Valorum, May 31 '17 at 08:27

I absolutely love pooped like a horse "fact". I don't think I will forget that one any time soon. Muggles have had plumbing of some kind in B.C. Wizards just plopped a deuce in the library and proofed it away. Unless you were young and learning then it might just explode everywhere. — coteyr, May 31 '17 at 09:09
@Valorum: following that logic they should have extended baby diapers to magic adult diapers. — PlasmaHH, May 31 '17 at 12:41
@Valorum it makes you really consider the purpose of the robes. — Daenyth, May 31 '17 at 14:25

Modern-style toilets were only added to Hogwarts during the 18th century:

When first created, the Chamber was accessed through a concealed trapdoor and a series of magical tunnels. However, when Hogwarts’ plumbing became more elaborate in the eighteenth century (this was a rare instance of wizards copying Muggles, because hitherto they simply relieved themselves wherever they stood, and vanished the evidence), the entrance to the Chamber was threatened, being located on the site of a proposed bathroom. The presence in school at the time of a student called Corvinus Gaunt – direct descendant of Slytherin, and antecedent of Tom Riddle – explains how the simple trapdoor was secretly protected, so that those who knew how could still access the entrance to the Chamber even after newfangled plumbing had been placed on top of it.

(Pottermore, Chamber of Secrets)

Whoever did the upgrade is unknown.

The Chamber of Secrets was originally accessible from the Chamber of Pots. – Sneftel May 31 '17 at 10:42

In fact, its original name was The Chamber of Secretions. – Hellion May 31 '17 at 13:42

The Chamber of Excretions is where the Philosopher's Log was found. – Robert Columbia Jun 01 '17 at 04:44
