When we do insets the rsailland stiles are 1-1/2" execpt the upper/wall cabinet to rail, it is 2". The 2" is to accomadate a riser, it finishes at 1-1/2" with the riser installed.
The white base with the cook top is just under 15', the black vanity is just over 13', the black tall with what will be glass doors is 12'ish.
The black vainty tower is just to show a fun door to make.....
We did have a 23' base with insets, we split a stile at 3/4-3/4, Dominos and screws make the seam pratically invisible. The unit was shot joined the separated for transport.
and yes, I'm getting to old to be moving these things....
