I wouldn't make this up even I could. I am LITERALLY fixing the toilet mechanism with the tank lid off and checked HN while waiting for a hot glue gun to heat up. I'm thinking Pulp Fiction divine intervention.
I guess we take it as a given since no one here is talking about it, but why does the toilet lid need to be so overly heavy? Is there any specific functionality that requires it to be out of that material and so big?
I assume that toilet lids are ceramic to have the same durability and antiseptic properties as the rest of the toilet, and that they are made thick enough to not break if dropped.
There are probably other materials that would also work, though... I'd expect any material used for toilet seat lids (plastic, or coated wood composite) satisfies similar constraints.
Incidentally, ceramic can become razor-sharp when broken, so the article's suggestion of making lids easier to break carries its own set of risks.
Maybe it's extra material to quiet the otherwise annoying sound of the refill after every flush? (since the tank functions a bit like a loudspeaker pointed up) If so, a bit ironic in the context of this post.
you can buy light plastic toilet lids if you like, in fact, they are rather cheaper than the more solid kinds.
I don't think there's really anything wrong with plastic toilet seats, but they feel less good, I think, than the heavier, more solid toilet seats.
The worst, in my mind, are the foam/shag carpet covers. those just seem wrong and gross - I mean I imagine my reaction is completely irrational, but I remember once I moved into a very cheap aparment; the toilet seat was sealed plastic covering foam in a way that the toilet seat was actually cushioned. something about it really squicked me out; the first night I went to the hardware store and bought a regular solid toilet seat and installed it.
Personally, I like keeping a heavy seat and just installing a dampener hinge, though I suppose that wouldn't help if you drop it during installation.
Just a guess, but because the base of the toilet needs to support users of all body weights, a sturdy material like porcelain (or clay) is used. The tank lid is likely poured and fired at the same time as the base so that they match. Agreed that it makes for a darn heavy obstacle to get at the mechanism. And to all who have posted about having tinnitus, I feel your pain. My left ear has been affected for two years now and I've had to learn to live with it. I hope you all fare better.
It's actually commonly made of thin plastic where I live, except on more fancy/modern toilets, so no, it doesn't have to be that way. But it does look fancier.
