Sure, we offer 18 inch and 15 inch wide pullout trash cabinets. A size in between is not possible, as the pullout trash units are fixed width and cannot be custom sized.
You can use a single door cabinet with a drawer above, then install an aftermarket trash pullout in the lower opening. We recommend a floor mounted pullout for best stability.
The interior width of our base cabinets is approximately 1.5 inches less than the listed cabinet width. For example, a 16 inch wide cabinet will have about 14.5 inches of usable interior width behind the door.
