How to Paint Kitchen Cabinets Without Ruining Your Kohler Kitchen Sink (or Your Toilet)

If you're planning to paint kitchen cabinets, here's the advice I'd give my past self: don't trust your prep work until you've written it down. Nine out of ten mistakes I've made in renovations weren't paint problems. They were planning problems. I've documented roughly $12,000 in wasted budget since 2017, and at least half of that came from rushing projects I thought were simple.

Simple. That was my first mistake.

The project that finally forced me to write this checklist was a kitchen and bathroom refresh before my niece's graduation party. We painted cabinets, installed a Kohler kitchen sink, switched in a Kohler Adair one-piece elongated toilet, replaced some door trim, and hung the grad cap in a shadow box. On paper, it was a five-day job. It took nine. Here's what I learned, in the order I learned it.

How to Paint Kitchen Cabinets: The 90/10 Rule

The first mistake happened before the paint can was opened. I assumed all cabinet doors were standard sizes. They're not. We removed six cabinet doors and three drawer fronts but didn't label which door came from which frame. After painting, two doors didn't align properly. I want to say we spent an hour matching them; it was closer to four. Throw in the drawers, and that's a full afternoon wasted.

The frustrating part isn't the paint. It's the prep work that feels unnecessary until it's too late. Grease on cabinet faces will make fresh paint bubble. Paint that looks fine on drawer fronts can look cloudy on cabinet bodies because the old finish was different. Primer matters. I skipped primer on my first cabinet project because the paint label said 'primer included'. That project needed a second coat within six months.

Here's the process I now follow:

1. Number each door and cabinet with painter's tape before removing anything.
2. Clean every surface with a degreaser, then rinse it off. This is the step you'll be tempted to skip. Don't.
3. Scuff-sand all glossy areas with 220-grit sandpaper. You're not removing the finish. You're giving the primer something to grip.
4. Prime, sand lightly, then paint thin coats. Two thin coats beat one thick coat every time.
5. Wait the full curing time before putting the doors back. 'Dry to the touch' is not 'ready.'

What was best practice in 2020—like spraying latex directly over old laminate—is more likely to fail than a modern approach using a bonding primer. The fundamentals haven't changed, but the execution has transformed. That's a good thing, but only if you respect the process.

Kohler Kitchen Sink: It's About Clearance, Not Just Looks

We picked a Kohler kitchen sink because the brand's reputation for quality is solid. I've installed them without issues for years. But here's something vendors won't tell you: a beautiful sink will look terrible if your faucet isn't positioned correctly. Most buyers focus on basin depth and finish and completely miss the clearance between the faucet spout and the sink floor. If that number is too small, you'll fight every pot, every day.

I assumed the deeper basin would work with the existing faucet. Didn't verify. Turned out the extra inch of depth meant the sprayer barely reached the bottom. That's a subtle thing you don't catch until the sink is installed and the faucet is mounted. Then it's a headache.

Also, if you're painting kitchen cabinets in the same week, cover the sink. I accidentally dripped paint stripper on the faucet finish while removing an old paint spot from a cabinet edge. It etched the surface. That was a $180 mistake. A replacement faucet doesn't automatically color-match, either. The new one looked slightly different until I replaced the whole unit.

Ballpark reference (based on publicly listed prices, January 2025): a quality kitchen faucet runs $150-$400. Prices exclude shipping and installation, and they vary. Verify current rates before you budget.

Kohler Adair One-Piece Elongated Toilet: Check Your Rough-In First

The toilet was supposed to be the easy part. I ordered a Kohler Adair one-piece elongated toilet because the one-piece design eliminates the crevice where the tank meets the bowl, and the elongated bowl is more comfortable. I assumed the rough-in distance was the standard 12 inches. It wasn't. It was 10.

I said 'standard 12-inch rough-in.' The salesperson heard 'yes, that one is fine.' We discovered the mismatch when the toilet sat nearly two inches off the wall. We were using the same words but meaning different things. The fix was a spacer kit, which was ugly, and then a different toilet, which was expensive.

Measure from the wall to the center of the floor bolts before ordering. If that number isn't 12, don't assume the toilet will fit. Same for bowl height. An elongated toilet is comfortable, but it extends roughly 2-3 inches farther into the room than a round bowl. In a tight bathroom, that space matters.

The surprise wasn't the toilet's performance. It was how much time we lost on a part that has only one job. Learn never to assume someone else's 'standard' matches yours.

Ballpark reference (based on publicly listed prices, January 2025): mid-range one-piece elongated toilets run roughly $300-$800. That's not a quote—just a reference point. Prices vary by region and seller.

Door Trim: Small Mistakes Multiply

We replaced door trim in the hallway during the same week. That was a scheduling mistake—different projects kept interrupting each other. But the trim itself taught me a useful thing: when removing old trim, cut through the paint line with a utility knife first. If you don't, you'll tear chunks of drywall off. That's not a trim problem; that's a wall problem.

The drywall repair added two days to the schedule. Actually, three. The joint compound had to dry twice, and I'm being honest about that because I almost wrote 'two' in this article.

If you're doing trim and cabinet painting in the same project, do the messy trim work first, patch walls, then paint cabinets. That order isn't exciting. It saves you from cleaning sawdust out of wet paint.

The Grad Cap That Started It All

Why did we do all this? My niece was graduating college. Her grad cap sat on my toolbox while we worked, waiting to go into a shadow box. It was the emotional anchor of the project, and also the easiest thing to forget.

Decorating a space for a life event is a different challenge than routine maintenance. You're up against a date on the calendar. I've learned to work backward from that date: pick the deadline, subtract two days for surprises, and then subtract one more day for the surprise you didn't predict. It's not a scientific formula. It's a buffer.

When Not To Trust This Checklist

Here's the boundary condition: I'm not a contractor. I'm a facilities manager who documents my own failures. If you're doing a full remodel, hire professionals. If you're only painting cabinets, this checklist might be more than you need. If you're installing a Kohler Adair toilet or a deep Kohler kitchen sink into an older home, have a plumber check the rough-in and supply lines before you buy anything.

The fundamentals haven't changed: measure twice, plan backwards, respect finishes. But the execution has transformed. Online forums, video tutorials, and better products make DIY more accessible. Just don't mistake easy access to information for time saved.

Hope this saves you a few hundred bucks. It would've saved me a lot more.
