Wow, I have not bought any type of commercial soap for a couple of years.
The kitchen has PET bottles (with dispenser caps) with liquid dish soap. They get replenished from the gallon dish soap container (with dispenser) that is next to other gallon liquid laundry soap dispenser (laundry has more CO and it is thinner, I like thicker for dishes, DH likes thinner for laundry). The outside sink has a bottle with our dish soap too of course. 1/2 bathroom has a shelf with a few of the holiday swap soap that are still to be used, a bar of lavender sea salt and a bar of almost gone hand scrubber soap on the sink. Full bathroom has 4 bars in the shower and a bunch in a basket display waiting to be used. There is a bottle of my bath grade lavender liquid bastille next to a larger bottle with apple cider vinegar. I was using the liquid bastille until I tried the Genny shampoo bar.
We also make our tooth paste (and tooth soap), deodorant, and all lotions and massage oil. We even make our own personal lubricant. However, DH still uses a commercial deodorant, mine is underpowered for him, but I like it and use it myself.
Yesterday I tossed the last empty bottle of commercial hair conditioner. It will be replaced with a pre-shampoo treatment that I am working on.
