Has anyone used these before? Having trouble figuring out how to install them. I have three to do. Can't figure out how to layout the holes to mount the guts.
The instructions are not very detailed nor is there much online either. There is a sheet metal picture frame that screws to the existing tub. What looks like a traditional residential panel cover screws to the picture frame. The trick is how to locate the interior and mark the mounting holes when it's all hidden by the cover.
