See the finished room before you move a sink

A hand sketch, two layout options, one finished result — how I test a rehab kitchen and hand the vision to my cabinet guy.

There's a moment in every rehab where the contractor's looking at you, waiting, and the answer is expensive either way. Move the sink to the corner, or leave it? Once the plumbing's in and the cabinets are hung, changing your mind costs real money. For years I made that call with a tape measure and a gut feeling, and I was wrong often enough to remember it.

Now I don't guess — and I don't look at just one version. I see the finished room first, from a couple of angles, before a single cabinet goes in. Here's exactly how I did the kitchen above.

Start with the rough sketch — with real numbers on it.

Not a pretty drawing. A hand sketch on graph paper with the actual dimensions: the 106-inch run, the 105-inch wall, the 36-inch fridge, where the dishwasher and range land. That's the inset in the layout shots. Feeding the AI real measurements is what keeps it honest — it's solving my room now, not drawing a magazine kitchen that happens to look nice.

Render the options — and put them side by side.

Here's the part that actually earns its keep: I don't ask for a layout, I ask for a few, rendered onto a photo of my real room so I'm comparing my actual walls and window, not stock kitchens. On this one I looked at two. One kept a straight sink wall with the window centered over the sink and the dishwasher to its right. The other pulled the sink into the corner to open up counter space and reuse the existing plumbing. Seeing them both — shown, not described — is what let me choose. The corner version won: more counter between sink and range, dishwasher right in the prep zone, work triangle intact. The callouts on each image are the layouts defending themselves.

Option A — straight sink wall, window centered over the sink, dishwasher to its right.

Option B — corner sink, more counter, plumbing reused. The one I chose.

Lock the finish, render the final — and that's what I hand over.

Once the layout's settled, I have it render the room finished for real: cabinets, counters, fixtures, floors. And that last image doesn't just sit on my phone — it's what I hand my cabinet supplier and my contractor. Instead of me trying to describe "light shaker, corner sink, uppers above the fridge" and hoping we're picturing the same thing, we're all looking at one image. It's the cheapest alignment I've ever bought — it heads off the "wait, that's not what I thought you meant" conversation before the boxes are cut, not after.

How it actually turned out — the corner sink, built.

The tool I use for this one is ChatGPT — it's what I reach for when the job is turning a sketch and a photo into something everybody can look at. The prompt shape:

"Here's my hand-drawn layout with dimensions and a photo of the actual space [attach]. Render two layout options onto this real room — keep my window, wall positions, and dimensions — and label the tradeoffs of each. Once I pick one, render a final finished version in [your finish direction] that I can hand to my cabinet supplier and contractor."

Where it breaks — and it does.

This aligns everyone on the look; it does not replace your measurements or your materials list. The dimensions live on the sketch, the finishes on your actual selections — the render just makes sure you, the cabinet guy, and the contractor are building the same kitchen in their heads. It'll still occasionally invent a detail or float a finish that doesn't exist at your price point, so confirm the specifics before anyone orders. Treat it as the shared picture, not the cut list.

The play: on your next rehab, before you commit a layout, run it — a dimensioned sketch, two or three layout options rendered onto the real room, then a final finished version once you choose. Use the options to catch the expensive mistake while it's still free to move on a screen. Then hand the final render to your supplier and your contractor, so everybody's building the same picture instead of their own.

Know someone about to gut a kitchen? Forward it — that's how this list grows. And hit reply: what's the layout call you've second-guessed after the cabinets were already up? I read every one.
