The Sektion sink cabinet has a flimsy back. And the back does not allow access to the wall if there is a plumbing issue. We also have a cleanout in the back wall (although if we use compression fittings, the cleanout might be removed). Our current cabinet has an open back. Given that we are replacing the sheetrock with purple board and fresh paint, I prefer a clean open back for potential maintenance and sealing the space for water proofing. However, the instructions for assembly call for the back to help square the cabinet. Any hacks to get an open back (e.g., steel cross bars like on the oven cabinet)? Opinions about why/how to do this, or why/how not to do this, are welcome.
