Each thing gets washed once, with the appropriate chemical if needed.

Generally for the toilet bowl, something with bleach.

For surfaces like the toilet and sink, especially in a bathroom, I usually swap between using just some vinegar and Fantastic all purpose cleaner. Vinegar is fine most weeks, Fantastic once in a while to get some of the stuff Vinegar may not have got properly with those extra chemicals that it has but I could easily go months without needing it.

I use water and a microfiber cloth for the mirrors and the faucet, a drop of dish soap if there’s something on it (like dried toothpaste spittle). This also works for walls most of the time if you wipe those, but I don’t wipe my walls very regularly, maybe once a year.

Hot water is fine for the tile floor too, maybe it gets something stronger a couple times a year.

You don’t need a lot unless someone in the household is sick with something that could be transmitted through a bathroom. Then hit it with harsher chemicals.

One thing to note may be that in certain warmer climates, there are other considerations for mold and bacterial growth that I do not have to worry about where I live (in a cooler climate)
