Cost: 10-30$
Installation: 20min with basic tools on your existing toilet.
Usage: tons and tons of online tutorials because 1/3 of the world already use that daily. But you can also figure it out yourself easely, it’s way easier than managing node_modules on a shared project.
Even cheaper alternative: a simple plastic bottle half-full and half bend. Many cheap labours in my city (Paris, fr) use one at work (cook, night cleaners, construction…). While the bourgeoisie fight for pooping clean during a world crisis, their Pakistani labor do they shit as usual. We should be inspired.
