Thanks to the Canadian company Modpools, your dream of having an expansive pool—or hot tub—might be more affordable and eco-friendly than you’d otherwise assume. They are turning shipping containers into swimming havens, and we’re all about it.

Traditional in-ground pools are notoriously a headache to install: the digging, the molding, the waiting. None of that is a factor with Modpools. According to the company’s website, you can be swimming the same day your pool is delivered. Prices range from $16,500 to $39,900, depending on the size (HomeAdvisor notes that an average in-ground pool can cost from $35,883 to $62,882)
