I Almost Ruined My Tile Before Finding 35.5 inch blinds

I just spent six weeks living on takeout and lukewarm coffee while my kitchen was a construction zone. The goal was simple: a clean, modern look with floor-to-ceiling subway tile. It looked incredible right up until I tried to install the window treatments. I had a standard 36-inch blind in my hand, a drill in the other, and a sinking realization that my new tile had narrowed the frame by exactly half an inch.

Trying to force a standard size into a custom-tiled space is a nightmare. I nearly took a hammer to my new backsplash out of pure frustration. That is when I realized that 35.5 inch blinds aren't just a niche size—they are the only thing that stands between a professional-looking kitchen and a DIY disaster.

• Standard sizes will either leave huge light gaps or scratch your expensive tile.
• Inside mounting is the only way to preserve the 'clean line' aesthetic of a new kitchen.
• Motorization is a survival requirement for over-the-sink windows.
• Precision measurement is non-negotiable when dealing with rigid materials like stone or ceramic.

The Over-the-Sink Nightmare

The window above the kitchen sink is arguably the hardest spot in the house to manage. During my remodel, I didn't account for the 'stack' of the materials. Between the thin-set and the tile itself, my window opening shrunk. What used to be a standard opening was now a tight 35.5 inches. I stood there with a 36-inch blind I'd bought from a big-box store, feeling like an idiot. It wouldn't even clear the top of the frame.

Most people don't realize how much a kitchen renovation changes the geometry of a room. You add a backsplash, you add trim, and suddenly your 'standard' windows are anything but. I spent two hours trying to figure out if I could shave down the headrail of a cheap plastic blind before I realized I was going to ruin the whole look of a $20,000 remodel for the sake of a $40 shade. It was a wake-up call.

Why You Can't Finesse a Half-Inch Gap Against Hard Surfaces

Physics is a cruel mistress when it comes to window treatments. If you have a 35.5-inch opening and you buy a 35-inch blind, you're left with a quarter-inch gap on both sides. In a bedroom, maybe you can live with it. In a kitchen, against crisp white tile, those gaps look like a mistake. They leak light, they show the window hardware, and they scream 'off-the-shelf junk.'

But the alternative is worse. Trying to jam a 36-inch blind into that space is a recipe for cracked grout. When you're dealing with hard surfaces like tile or quartz, there is zero 'give.' If the blind is a fraction too wide, it will scrape the finish off your tile or, worse, put enough pressure on the side walls to pop a tile loose. This is why hunting down exact-fit 35.5 inch blinds became my obsession. You need that 'goldilocks' fit where the blind clears the sides by a hair, but covers the glass completely.

Outside Mounting Wasn't an Option

A lot of people told me to just 'outside mount' it—bolt the blind to the wall above the window. Absolutely not. I didn't spend three days pick-and-placing subway tile just to drill four massive holes into it. Outside mounting hides the window trim and breaks the clean, recessed look that makes a modern kitchen feel high-end. It’s a compromise I wasn't willing to make.

Dropping the Pull Cords (And Saving My Wet Sleeves)

Once I found the right size, I had to deal with the second kitchen problem: the reach. If you have a deep farmhouse sink like mine, reaching over a pile of dishes to grab a pull cord is a great way to end up with wet elbows and a knocked-over glass of water. I've spent years fumbling with tangled cords while my hands were covered in soap suds.

I decided to stop the madness and go motorized. When you look at why choose smart blinds, the kitchen is the primary use case. I don't want to touch my blinds with greasy fingers. Now, I just say, 'Alexa, close the kitchen,' and the shade drops to exactly 50% while I'm finishing the dishes. No cords, no reaching, and no wet sleeves. It’s the kind of small luxury that makes the whole house feel more intelligent.

Getting the Motorized Setup Right

For the kitchen, fabric choice is just as important as the motor. I went with light filtering sheer shades because they block the glare from the morning sun without turning the kitchen into a cave. You want to be able to see your coffee maker without being blinded, but you also want to keep the neighbors from watching you eat breakfast in your bathrobe.

The installation was surprisingly painless once I had the right dimensions. I used a Zigbee-based motor that paired with my Hubitat in about thirty seconds. The motor noise is a non-issue—it’s a low hum that is quieter than my dishwasher. The only real headache I had was a firmware update that stalled halfway through, but a quick reset (holding the pairing button for 10 seconds) fixed it. Pro tip: secure your brackets into the wooden header of the window frame, not the side tile, to avoid any risk of cracking the stone.

The Measuring Rule That Saved My Walls

If you take away one thing from my struggle, let it be this: measure in three places. Top, middle, and bottom. My window was 35.6 inches at the top and 35.4 inches at the bottom because the tile wasn't perfectly plumb. You always have to order based on the narrowest measurement. If you don't, that headrail is going to get stuck halfway up, and you'll be back to square one.

This level of precision isn't just for small kitchen windows, either. I've applied the same logic to the rest of my house, especially when selecting 60 inch blinds and shades for the living room. Whether it's a small 35.5-inch gap or a massive five-foot span, the difference between 'that looks okay' and 'that looks custom' is all in the half-inch increments. Don't settle for 'close enough' when you can have an exact fit.

FAQ

Will a 35-inch blind work in a 35.5-inch opening?

It will fit, but it won't look great. You'll have a 1/4-inch gap on both sides, which lets in light streaks and looks like a DIY mistake. Always try to get as close to the actual measurement as possible.

Can I trim 36-inch blinds down to 35.5 inches?

Only if they are specifically designed to be 'cut-to-size.' Most motorized or high-end shades have internal components and motor housings that cannot be cut without destroying the unit. It's much safer to order the exact size.

Is it hard to install blinds over tile?

It can be. If you have to drill into tile, you need a diamond-tipped drill bit and a lot of patience. This is why I recommend 'inside mounting' to the top wooden header of the window frame whenever possible to avoid the tile entirely.
