If the time and money that go into buying and maintaining a house feel draining, you could always downsize.

For just shy of $26,000, you can buy a tiny home with a bathroom and kitchen delivered to you by — who else — Amazon.

Chinese company Hebei Weizhengheng Modular House Tech Co. (WZH Group), which is headquartered near Beijing, sells the 20-by-40-foot insulated, expandable container home on Amazon, which comes with solar energy panels, for $24,800, plus $1,000 in shipping.

All homes made by WZH Group are built so owners can wire them for electricity, but some also offer solar panels as an option, Ada Yin, who sells modular homes with WZH Group, tells CNBC Make It.

Yin says WZH Group has "sold many homes" in the U.S., Australia, Canada and Germany. The Amazon listing suggests a range of ways owners can use the tiny house, from home office to retail space. In the U.S., these tiny homes are more frequently lived in by families, whereas they're popular as dormitories in Germany, Yin says.

Interest in downsizing your home has been growing in recent years thanks in part to a number of television shows documenting the trend: HGTV has two series,"Tiny House Hunters" and "Tiny House, Big Living," and A&E''s "Tiny House Nation" is in its fifth season. A February 2018 poll from the National Association of Home Builders found 63% of millennials would consider buying a tiny home, which is defined as less than 600 square feet. Only 45% of baby boomers and 29% of seniors felt the same, the survey finds.

One reason people turn to the tiny home life is to be more environmentally responsible, says Ryan Mitchell, the managing editor and owner of The Tiny Life, an informational website about living in small homes. Mitchell, himself, lives in 150-square-foot house that he built by himself in 2012. Small homes are more "green" than their larger neighbors because they use less material to build and require fewer resources to power and maintain.

Mitchell says he's saved $100,000 in rent since moving into his tiny home, and he enjoys a simpler, more eco-friendly lifestyle.

Another reason tiny homes have been capturing headlines recently is they are relatively inexpensive and available on Amazon. The "media blitz" has been nice, says Robin Pekkala, a spokesperson for Allwood, an eco-friendly online retailer that sells a number of tiny, small and mid-sized cabin kits. But the homes themselves are not new: Allwood has been selling the wooden cabin kits since 2012, Pekkala tells CNBC Make It.

The Allwood cabin kit arrives in parts — wood, windows, doors and hardware — and needs to be assembled. If a customer wants to add electricity or plumbing that has to be done separately, Pekkala says.

Some of Allwood's structures are not made to be homes. The Solvalla model, which sells for $7,350 (with free shipping) on Amazon is more of an enclosed outdoor space. "[It's] way too small to add anything and we don't recommend doing so," Pekkala says of the structure that includes just 86-square-feet of interior space.
