After the top pieces were cut, I used the jigsaw along the edges and cut the slats off. They were glued and pegged so cutting was the easiest way to get them loose.
Once all the pieces were cut, I sanded down the edges.
I planned on having a hidden stool at the bottom so after measuring the width of the pedestal sink, I removed 11 slats and cut them down to allow for the stool.
I then nailed the slats onto the curved pieces.
