We have a 2499 with a bathroom door that bounces around if not quite level or the stabilizer jacks aren't down. I got the idea here, from JohnB I believe, but this is the solution that came to me as I was looking for the parts.
I found this cabinet door catch at Home Depot on the shelf with all the other magnetic catches etc. This one is sourced in Canada, but I expect a similar item would also be in US stores. The larger of two sizes turned out to be a perfect
fit as I'll show you later.
I removed the shower access cover from the bedroom wall to see what I would be drilling into. I mounted the longer female part of the clasp on the panel below the shower because that way the bottom screw went into the 3/4" framework behind the panel. There was just enough room to slide a pencil under the door and mark the location of the bottom hole. With Karen's help, I glued a small backing block on the panel from in behind so that the top screw had a full depth of wood to turn into. Karen turned the top screw in right away while I pushed on the backing block--that way the screw snugged the block and glue up against the back of the panel. There is a good bit of 3/4" framework behind this panel, just not in the right spot to drill into except for the bottom screw--so everything actually is quite solid.
Vertical alignment of the two parts is critical or they won't mate at all and there are no second chances. Horizontal isn't quite as critical and as you can see in the photo, I was off by a bit here. I placed the male half right at the edge of the door and marked the edge--not easy to do with bifocals and my cheek on the floor.
Despite the angle of the door, the clasp catches perfectly--and even better--the rubber bumper hits the shower just as it always has just as you push the clasp together so there's no undue pressure on the paneling.
There is a slight hazard of stepping on the male part of the catch when the door is closed and you're standing in front of the sink. I tried to, but it's very unlikely.
