Several decades ago I was tank soldier and my unit went to a training area at the coast of Wales, Great Britain. There were several tank shooting ranges and the Brits had built some very simple outhouses for those who were training there. They even provided toilet paper. This came in single sheets in a 12 x 8 centimeter (4.7×3.1 in) format. They where yellowish in color with a glossy surface that made them water resistant. That made somewhat sense in the rather foggy surroundings but did not help with the intended purpose. Printed in blue on each sheet was "Her Majesty's Property". I pondered if it would be lèse-majesty to actually use it. As a person in need I did it anyway. The sheets turned out to be rather useless for cleaning anything.
The story comes to mind as the virus panic causes a run on toilet paper at least in some countries.
The run points to a lack of personal infrastructure.
Toilet paper is certainly not ideal for cleaning ones butt. It is okay for removing the rough stuff but after that it tends to spread the rest rather than to remove it.
Separate bidets (vid) are good for a real cleaning. They are widely used in Italy and France but require extra space and installations. They are excellent for their purpose but when I lived in an apartment that had one I found it rather inconvenient to use (and clean) it.
If one is sitting on a water toilet why not use its water supply to also clean ones ass?
In some warmer Asian countries Bum Guns (vid) are widely used.

These are special shower heads on a hose with a trigger. In warm countries they are excellent to clean one's butt thoroughly. But in colder areas it is an uncomfortable process as they are connected to the toilets cold water supply. They also require, like a bidet, an extra towel or toilet paper to dry oneself after use.
In Japan one finds toilets that play music, have inbuilt shower heads and dry blower, odor suppression and other gimmicks like a chemical analyses of ones urine. They are also expensive, need a larger installation and are hard to find in Europe or North America.
The solution I implemented for myself several years ago is of a minimal Japanese kind. I use a toilet seat with a bum shower and dry blower (in German). It fits on any standard German toilet and it is quite easy to install or to remove.

At the press of a button the stainless steel shower head appears from its housing in the back of the seat and a jet of warm water starts to blow at ones butt hole. The water pulses and the shower head moves back and forth. After a minute or so the head retracts while cleaning itself with some extra spurts before it vanishes again. Then the dry blower starts.
Here is a video from a U.S. distributer of such products that demonstrates the above process.
Some models have a certain amount of preheated water while others use a flow-type heater and then mix a warm and cold stream to the desired temperature. The second type is preferable as it provides an unlimited supply of warm water.

The seat is also heated which makes it very comfortable to use it in my usually unheated bathroom. The temperatures and jet position are adjustable and can be preset. I use the energy saving mode which ensures that heating only starts when one sits down. Energy and water consumption of the device are minimal. They are certainly less than what is used to produce the toilet paper I would otherwise have to use.
There is only one button that is used daily. It starts a one minute shower cycle followed by a 30 second dry blow. After several years of using the seat daily I can confirm that the results of this process are excellent. One leaves the toilet with a clean and dry butt. I still have toilet paper in reserve but that is now mostly used for other than its original purpose.
There are types of such seats which have more features like odor suppression, lighting or automatic lid opening and closing. It all depends on the price. I paid less than 500 Euros for my version and I believe that it was an excellent investment. Instead of using several roles of toilet paper per month I am down to one or two per year.
Prices in the U.S. for such devices seem to vary between some $300 up to and above $1,000. The middle range will do. One does not need more than the basic features. I personally find an attached side control panel better than a remote control which is guaranteed to be misplaced or out of battery juice just when one needs it most.
Consider that such a toilet seat cost about the same as a smart phone. Everyone now seems to carry one of those. But only few people use a similar priced device for their daily hygiene. Why is that?
Note: I have no relations of any kind with any of the linked companies.
