When nature calls, most of us head to the nearest toilet to do our business. If the bathroom has the Kohler Numi that launches in the U.S. at the end of the month, you might be tempted to hang out for a while.

The customizable "smart toilet" lets you adjust seat position, water temperature and pressure, ambient lighting, even audio. Numi not only has a built-in music system with rear speakers, but also an FM radio and audio input jack for an MP3 player.

It has an adjustable heated seat and foot warmer, too, plus an integrated stainless steel, self-cleaning bidet wand with a dryer. A motion-controlled seat and lid can automatically open when you approach and close when you split.

Tripping a bar of light on the floor to the side of the toilet automatically raises the seat, while the toilet automatically flushes when you walk away.

There are a couple of flush cycles: a water efficient "eco" flush that uses 0.6 gallons per flush or a full flush at 1.28 gallons. And flushing is extremely quiet.

The attractive toilet sports a minimalist design. It comes in white or biscuit, and it includes a removable handheld touch-screen remote that lets you control various settings for up to six users and in a dozen different languages. (Numi has already been introduced in some Asian markets.) You can recharge the remote's lithium ion battery and store it in a wall-mounted dock. The toilet itself plugs into an electrical outlet.

What might make your stomach growl is the $6,300 list price. David Kohler, president and COO of the Wisconsin-based business, acknowledges that Numi is priced "at the top of the market." But he says, "The luxury market's coming back in this country and (is) very strong in other parts of the world. This product is targeted at those consumers who want the best -- they want the latest in design and technology (and) want a fashion statement in their home."

David Kohler says Numi has been under development for five years.

Might video come next? Kohler recently took the lid off another product in China with an "entertainment remote" that provides Skype and streaming video.
