Here’s the vinyl plank you were looking for.
It’s made by a company called Novalis. It comes in 4x36 strips. While it covers the same square foot of space as a 12x12 square it does it in a different shape.

Words can’t describe how much easier it was to work with this dimension either. I’ve put down more than my share of vinyl flooring and this was one of the easiest jobs ever.
People can talk trash about peel and stick vinyl all they want but I really liked this stuff. Yeah, it can be cheap looking, but I don’t think this stuff is.

I can’t tell you how many times people would stand in the dining room and look in the kitchen and say, “Oh, you put wood down.”
Only after they really looked -- or after I pointed it out -- did they notice it was vinyl. Even then, most people would lean down and touch it! Here it is in our old kitchen so you can see how it looks down.

Wow! I still miss it. That old refrigerator? Not so much! The floor served us well for more than three years. It was comfortable to walk on, very durable and easy to clean. I almost cried when I ripped it up to start prepping for the new porcelain tile. It’s thick but you can cut it with a utility knife. Yet another nice feature.
And I can’t say enough about how much better plank size is to work with than square. It made getting around the awkward edges that cabinetry and doorways create very easy to deal with.
I think both Lowe’s and Home Depot carry it. (And I’m pretty sure it’s Lowe’s because I just saw some of it recently.) It’s something like 98 cents a square foot. They sell in both boxes of 30 and in individual strips which can be pretty convenient.
That’s a little pricey for vinyl, considering you can get some varieties of porcelain at that price and even cheaper, but it’s worth it.
It comes in two shades, this one being the darker of the two. The other is more of a lighter oak color. I still have almost a full box of it and I’m debating whether this might not be a good option for the laundry room floor – when I get around to replacing the crappy tile down there.
