Hey, it’s Steve from CT Home Repair and Tutoring LLC.
One of the best parts of this closet-to-bathroom project is making use of the space underneath. The plumbing from the new toilet runs right through the guest bedroom ceiling, so I decided to box it out and turn the area into a useful closet. Not only does it hide the pipes, but it also adds insulation to quiet down the noise from upstairs drains — no more echoing flushes waking up overnight guests.
I took pictures of the framing process so you can see how to do something similar in your own home — whether it’s hiding pipes, creating storage, or just reclaiming awkward space. If you can measure and screw in some 2x3s, you can handle this.
What You’ll Need (Basic Framing Stuff)
A tape measure, pencil, speed square, circular saw, drill, level, and 2x3s with screws. That’s it for this stage — no fancy jigs or pro tools required.
Step-by-Step: Framing the Closet
Step 1: Mark the Layout
Start by running a laser level across the ceiling to mark the exact path of the plumbing. I used a chalk line on the walls and floor to outline the closet footprint, making sure it enclosed the pipes without wasting space.

Step 2: Box Out the Pipes
Build the first section around the plumbing stack — cut 2x3s to fit snugly against the wall and ceiling, then screw them in place. I added blocking to support the pipes and keep everything stable.

Step 3: Complete the Framing
Frame the other side and top, ensuring everything is plumb and square. I used a level on every stud and will add additional blocking for hanging the closet rod.

What I Learned (and Why It’s Worth It)
Boxing out plumbing doesn’t have to be an eyesore — it can actually add useful storage while reducing noise from upstairs. This closet will hold linens and guest essentials, making the room more functional without eating up floor space.
Next up: Running electrical for a light and outlet, insulating around the pipes, and sheetrocking the whole thing. Stay tuned!
