I had a couple of hours yesterday to start moving piping around in the bathroom yesterday. First up were the drainpipes, which were pretty easy to get to and easier to extend with the right replacement fittings. The one on the right took a bit longer because I had to notch out one of the wall studs to get the pipe to clear. The one on the left might have taken 15 minutes in total, from cutting the wallboard to cementing the extension in place.

Then I started on the water supply piping. You can see where the cabinet edges are by where the blue tape is. I had to shut the main water supply off because I was still getting pressure upstairs, but I moved the left-side supply over and got one of the right-side pipes moved before I had to stop last night.

Does that look like shit? Yes. Will it clean things up under the cabinets and make life easier? Hell yes. Will anyone ever see it? Only if you’re looking at this post. 

Next, I’ll make a pass-through notch on the underside edge of the cabinets, then re-measure the supply pipes and use the hole saw to cut access holes through the backs and bottoms of each cabinet for the pipes. After that, I’ll set each of the cabinets next to each other and level them out before drilling holes to connect all three together as a level unit. Then I’ll take them apart, set them down over the holes and into place, and connect them back up as one unit before leveling the whole thing off and connecting it to the wall.
