I am sure there are other options out there, but you could build a box inside the cabinet to protect the plumbing and electrical. A box with a door or panel so you have easy access to those things if you need to fix something in the future.

Not sure what your budget is but if you really want space you could turn the sliding glass door into a single exterior door, and move the kitchen out into the space of half of the removed slider. It would have to be done right, and expensive, but what you are asking about will not work. And you would only be gaining 4-5" vs 3-4 feet. I did that in my old home, I removed the slider put a single Anderson Prehung Metal door in. I framed in a small window next to the new door, yours would be to the right of the door. You keep the pony wall, it would have to be moved out along with the plumbing in the slab, but that is not that difficult (for a contractor). Good luck.

Thanks. I'm not interested in making the kitchen that large. I also don't want to move the waste line because tension cables run through the slab.

We're mostly DIY'ing.

Will you be using an electrician and plumber?

"Is it possible to run these things through the sink and corner cabinets to the wall?"

Certainly, but just because you can do something, doesn't mean you should. That's a heck of a lot of work for minimal gain. Speak to your local division of inspection first, please. They are usually receptive and helpful to DIY homeowners. You do not want to risk a red tag.

You could check to see if its code to be able to run the water lines and electrical under the cabinets in the area behind the toe kicks. As long as your waste pipes have the right slope you could move the sink cabinet around as long as the waste line still comes up into the cabinet. The vent line might be a little more difficult but you might be able to tuck it up in the top back corner of the cabinets behind any drawers.
