Not to be the guy that tells you building codes are sacrosanct, but some things make sense. Laundry sinks for instance aren't just about having a sink nearby. They are about overflow and solve two common problems. The first is that the amount of water voided by most washers is too much of a flow for pipes. Especially pipes in older homes and especially pipes that aren't vented properly. Secondly washers tend to let off fuzz and lint which clog pipes.
The whole point of a large laundry sick is to be large enough to hold the entire water contents of your washer. I can say from experience that the alternative is much more trouble.

If you are actually looking for advice give me specifics and I can help out. I have done all of these tasks including natural gas piping.
