None of these things will make taking a bath all that much better, as you can probably set up a TV outside your bathtub on your own if you really want to, and who the hell needs to turn on their tub with their cellphone? But if bathing your naked body in a solid gold bathtub doesn't make you feel like a rich sonofabitch, nothing will. And with a list price of $47,200, that's just what you'll have to be to own one.

Not only does the Sorgente look expensive, but its unusual design also means you'll have to build the bathroom around it, instead of the commoner way of throwing in a plastic shell. The tub completely submerges into the floor, and creates that seamless effect by way of a specially designed brim seen in the picture below (think Infinity Pool for the water closet set).

Once you enter the pool, er tub, eight "hydrosilence" whirlpool jets massage your kiester after a long day of driving the Maserati around Rodeo Drive. Meanwhile, the entire tub is surrounded by a choice of teak or oak woods, or three different varieties of stone.

The bath brings lights, music and vibrations together to create a relaxing atmosphere. Four presets of new age music and soft lighting are included, but if you can only relax with Public Enemy and flashing strobes like me, everything is adjustable and the tub streams songs from your PC or Mac. One thing that threw off my man Mr. G was the vibration of the tub. Vibrating pulses pass through your body, but they sound much more intense than they feel. Fool thought he was getting a massage, but he was just shaken up a bit at best. Either way, it's a nice way to chill out and get clean. But for $13,000, they could at least install a milk fountain!

One thing that makes bathtime more relaxing is music, but due to the fact that listening to your iPod in the tub will probably kill you if done improperly, people are always looking for solutions to make this relaxation synergy happen. Hence MTI has created the Stereo H2O audio system, a bathtub that plays music right into the water with you. Yep, the bath itself is a speaker. Sounds pretty neat, actually, although probably not neat enough to make me want to lie naked in a pool of my own crapulence. Your mileage may vary. –Adam Frucci

The design prevents you from even realizing the technology is present. Speakers aren't housed outside in the scum of the bathroom, but within the tub itself. Sound waves shoot through the water, creating what feels like complete sound immersion. We're guessing it's more like 2.1 immersion, but cool nonetheless. Runs about $600 for 2 transducers, freaky woman taking a bath without water not included. – Mark Wilson
