Thank you for the video! I wish you could help us to do it! :). My hubby is afraid he can damage pipes, by mistake. He is saying you have to know exactly how and where to cut the wall, the pipes...
You can do it! Just use a box cutter to cut a small inspection hole about 6”x6”. You can even stick your phone in there and take a video since your head can’t fit in that hole. If you cut a spot for inspection and you need to repair later then use a “California patch” where you leave a large edge of paper on the replacement drywall piece. It’s really a neat trick so you don’t use tons of compound or buy that ugly mesh patch kit from HD/Lowes.
Thanks. We use it a lot to rinse out things in the laundry room. I’ve had no issues with this cabinet and sink after 1 year of family usage. Hope many more years to follow.
