Billy bookcase/Olsbo doors (best guess, Craigslist find)
We wanted to add more storage to our oddly huge master bath as well as figure out a solution for concealing the litter box and related paraphernalia. We found this rather beat up white Billy bookcase with doors on CL and saw the potential. We completely disassembled the entire thing, and cut a cat door hole in one side.
We penciled it on first- the bottom of the hole was aligned to where the litter box would hit, the sides were an inch or so inside of the shelf support holes, and for the curved top I traced a large bowl- then used a jigsaw to cut it out. We sanded and painted the sides, top, bottom, and middle pieces a lovely aqua color.
We had considered leaving the doors and movable shelves white, but after reassembling it (with wood glue for added sturdiness) the white still looked grimy next to the new paint, so I got some contact paper that matched the paint color pretty well, and wrapped the shelves and the inset door panels.
The top now allows for decorative bathroom storage (still working on filling it up!) and then when you open the doors, there is easy access to clean the litter box with a scoop and waste receptacle on the left. The shelf holds paper towels, waste bag refills, and other cleaning supplies. The litter pan we use is actually a 6 inch deep full size stainless steel steam table pan. It works perfectly except that it does stick out a little in the back so the shelf isn’t flush to the wall (since we got the bookcase on CL, it didn’t come with the back piece) Anyway I am super proud of it, and both my cats seem to like it too!
