Hi Alisha! As far as holes, we really like you to make the cut because each bathroom has different plumbing and if we pre-cut, sometimes it won’t work with your plumbing. It is much easier to have you do it on your end to make sure everything is accurate. It is also hard for us because we cannot physically see your bathroom to ensure things align. We would hate to even be a fraction off because it could cause a giant mess on your end. Does that make sense?
