The kitchen shown in the first season of Keeping Up With the Kardashians is *not* their current home. Some fans believe the kitchen shown is the same one used in the show, but there is no evidence to support that claim.
The Kardashians have lived in multiple different homes since the show began. For example, Kris Jenner currently lives in a different mansion in Calabasas, while Kim Kardashian lives in a luxurious home in Hidden Hills, California.
So, while the house shown in season 1 of Keeping Up With the Kardashians might look familiar to some viewers, it is not the same house they live in currently.
