I suppose we can start with
Masao, and keep lowering the bar to limbo under:

For further context: Masao used his toilet for a garbage can; with the bowl often full of coffee, slices of bread and/or cheese, and would burn his mail in it (he claimed that flushing his mail without burning it would allow homeless people living in the sewers to read it). The floor around his toilet was so rotted that he lived in constant fear of falling through into the crawlspace while shitting and; so, reinforced the floor under the toilet with cinder blocks.
The rest of Masao's bathroom was unusable due to the bath tub being perpetually filled with stagnant water and years-old dirty dishes which Masao would still bathe in; occasionally scrubbing cups and bowls with shampoo. The bathroom sink was similarly full of years-old filthy dishes.
