[Misc] Why do toilets have rims?

[Nottseagull]

Despite clocking up several thousand hours sitting on them, I've only just come to ponder this after seeing this ad

It's as if they were actually designed to harbour dirt and germs!

So what does one sit on then, to do a number 2?

We've been rimless for 3 year's now at CZ house , wouldn't go back

rim allows for the water to come out all round the bowl. rim less sends most water direct down the trap. i suspect the benefits of rim are overlooked, otherwise they'd not go to the toruble of making them (easier to make rim less).

Ours are rimless and I’ve noticed splashback when flushing. This has resulted in needing to put the lid down before pressing the go button

I have recently had rimless toilets installed and though they are easier to clean, I do find the odd spot of water escapes over the top of the bowl when flushed. Not a major issue as it's clean water, unless you're wearing pale trousers as it can look like the dot of shame.

Do you not put the lid down before you flush anyway?
That’s grim

It takes about 10 seconds for our soft close lids to close. You can't be hanging around all day.

I love a good rim. Oh!! Wrong thread.

 

[Questions]

I’ve often thought about the whole rimming process more than once. My sister in law had an exposed rim and I thought it was all wrong.

If you put the lid down how do you chuck a tissue in from the doorway?

I did have the pleasure of using one those Japanese electronic ones in a hotel a few years ago.

My rim had never been so clean.

This is the sort of answer I was seeking. I suppose I should really have asked if rimless ones flush as well as the traditional.
Anyway, Google now thinks I have a particular interest in public toilets...

Why wouldn’t you put the lid down before flushing anyway?

 

[Scappa]

Because without a rim what you would have, essentially, is a puddle (or an infinitely tall porcelain cylinder)

So that they don't fray at the edges.
