New toilet paper holder

We have installed a new toilet paper holder replacing the old one. The new one can be covered with a swivel cover so it will stay dry. It automatically turns the roll as you open the cover to unravel a sheet or two of paper so you have something to pull on. It is quite nice as it keeps the paper clean and dry at all times. It is easy to refill and takes all kinds of paper.
This is not straight forward. The new one is larger so you need to modify the opening. You will also need to trim a little away from the support behind the bulkhead. To trim that away I think I used a drummel.
