Toilet Paper Holders

The debates have been legendary – should the toilet paper roll holder be placed to the right or the left of the commode, and once installed, should the loose end of the toilet paper flap over the top or come from underneath? Placement of the toilet tissue holder is often driven by existing architecture and toilet location, so there are many options with no clear indication as to what is best. Regarding “over” or “under” TP placement, studies show that the over way prevents dirty hands from touching more of the toilet paper than necessary, plus it affords less of an opportunity for TP to graze the wall.
