Hi there!
A big fat 8 roll package of paper towels will last me over a year. Firstly, I absolutely detest them. I have a blue contractor version that is washabke, and ripped up towels that also can be washed. So PTs are strictly emergencies.
I leave a roll in each bathroom and in the kitchen and no one seems particularly interested.
TP is another matter. We go through a lot but prices are reasonable. I have up to 60 rolls at a time and stash extras in each bathroom. Boxes of Kleenex are used most often in winter, for obvious reasons.
