Available in a range of sizes up to 40-feet long, each Modpool comes with a suite of customization options, ranging from the colors of the exterior and cover, to the addition of glass panel windows, and features like a built-in jet system that creates a constant current to swim against. They also come equipped with specialized water sanitation and heating systems, meaning you can keep the water warm enough to be comfortable year-round (it can allegedly raise the water temp 86 degrees fahrenheit per hour in below-freezing air temps). If you want, you can even turn one end into a hot tub by adding a special divider and cranking the heat just on that side, all of which is controlled via a dedicated app.
Unlike an in-ground pool, or even the more standard above-ground options, they're designed to set up in literally a few minutes. And because they were initially built to be structurally sound enough to schlep around the world, they're easily shipped pretty much anywhere (though for now, the company is restricting delivery to the US and Canada).
