Been delaying the installation of my bathroom sink for a week trying to get around a 1 inch problem with the spacing of the holes in the wall mount sink I got vs the studs I want to lag bolt it into. The wall studs are already at an odd spacing but just 1 inch more of oddness would have saved the day. Nope! Finally bit the bullet and took off some wall tiles and opened up the wall to allow me to put a new brace in between the wall studs. One inch means instead of a 30 minute easy job I'm in for hours of bullcrap including having to solve the retiling puzzle. I cursed that thing for an hour

but in the end decided to do the extra work instead of risking a hack job. Truly the down side of a DIY project.
