I dunno. Pretty much the only thing that isn't open source would be the shower head, pumps, and water heaters. However, those technologies are frequently out of patent, with the "user interface" aka shower head being what is actually proprietary but, that is optional.

Modern pipes are made of copper and/or PEX. The plans for the plumbing are generally public records. Seems pretty open source or at least "source available" to me.

Water itself has rather well-known atomic "source code" of one oxygen and two hydrogens.

What even would "closed source" water be?...

Dude said shower, not the components that make up the shower

Dude said open-source shower. That implies access to the knowledge required to recreate it, thus, the components that make up a shower. I demonstrated that most showers could be considered mostly open-source or at the least "source available".
