Ah, the infamous ‘over or under’ debate.
Over = when the end of the toilet paper hangs over the top of the roll.
Under = when the end of the toilet paper hangs underneath the roll.
We don’t want to get involved... Ultimately, how you choose to hang your toilet roll is completely dependent on personal preference.
However, many people do argue that ‘over’ is the right way because it’s more hygienic, easier to use, and looks better. But hey, your bathroom is in your jurisdiction.
