I'm not fan of jacuzzis myself. Even while I had some unforgettable tsunami moments in them, I'm partial to the large, deep English bathtub. But I won't say no to this bathtub spaceship by Japanese bathtub company Spiritual Mode. [Trendir]

Just like a real steam boat, this six-inch version moves because of expanding steam pushing away from water. Mimicking the real thing further, there's a compact boiler and motor made of copper pipes and even a heat shield. You get things started by lighting a small "lamp" filled with olive oil and watching the steam come out before the boat zips across the bathtub.

The instructions provide the in depth details on the physics and go step-by-step from cutting and building the hull to putting together the boiler. All that's missing is a guide on how to whistle like Mickey Mouse. [Duckworks via Make]

The tub also features touch controls and a motion-activated hand shower. Unfortunately, it's only a concept—but the design was good enough to become a Red Dot 2009 award winner. [Red Dot via Born Rich via Unplgged via DVICE]

So instead of worrying about air-strikes and assassination attempts while I bathe, all I have to worry about now is how my ass will look, magnified by murky water and surrounded with flat bubbles. Great! [Product Page via Nerd Approved via Luxury Launches]

You hang the device on your shower head. The included proprietary cleaner bottles gravity-feed into the rotating nozzle and pump, powered by 4 AA batteries. You push a button after you're done showering and after half a minute of warning beeps, the turret fires off the cleaning fluid in a 360-degree pattern. It's supposed to be a robotic anti shower dirt artillery cannon. It is is not.

Over a few weeks, a mild and inexcusable pattern of soap scum (infantry in the army of shower gunk) built up onto my bathtub. Was it by chance some serious buildup? No. Some strong stuff in the purple squirt bottle applied and a non abrasive sponge took it right off.

Honestly, I think they're selling this thing on the fantasy of clean bathrooms and fear of mildew alone. The snake oil product, which I tested for about two months, might make a good base for an automated scarecrow weapon in the garden triggered by some motion sensor. But it won't do anything for your bathtub that a sponge, some elbow grease and the most caustic material your lungs and skin can handle can't do better and cheaper. Especially the original Scrubbing Bubbles stuff, which I am a fan of.

Robot bathroom cleaner, zero; human domestic man servant, 1.

UPDATE: Just got this hate mail from this guy, josh.pruitt@gmail.com

This is clearly an angry attack on a product. Lots of people I know
(self included) use this product and have been satisfied with its
performance for years. The article is completely biased and shows a
lack of research. There's no indication that Brian contacted Arm &
Hammer for help with finding out why the product wasn't performing as
expected. Just because a product doesn't work for you doesn't mean
it's "snake oil." This product isn't even related to the theme of
Gizmodo.

"Hello Arm and Hammer, your thingy I bought doesn't work. Can you please explain why? Oh, ok. Good answer. Thanks. Bye." *goes back to using lame shower cleaner with a deeper understanding of why it fucking sucks.*

They are call Vasabarca and Arca, respectively. The price range goes from frackinghell to yougottabekidding. [Antonio Lupi via Aqua—in Spanish, gracias Fernando]

The Bath-O-Matic is equipped to run on home automation equipment from AMX and Crestron if you want to fill your tub from the comfort of your couch, and can fit on tubs both old and new. It also includes a motorized plug so no water is wasted, and adjusts to pressure and outside temperature so you won't have to worry about getting burned. Just slap a toaster and an iPod on this baby, and I think we have a real winner. It sells for 4000 (about $8000) so you better get one before supplies run out. [Bath-O-Matic via CE Pro]

Two words: Bathtub Racer. We're talking fully motorized bathtub fun (No, not that kind of bathtub fun). For $17,000, you can get yourself 2 racers and an 65'x29' inflatable track. And we're not talking about a stupid little circuit track, this thing is a full on windy course.

Wait, did I just say $17,000? For a motorized Bathtubs and a track? Maybe I'll just wait for one to show up on Craigslist.– Ben Longo

The Royal Whale Bath is the ultimate in luxury bathdom. Probably Definitely created from the carcass of a real sperm whale that was brutally murdered, miniaturized and cast in porcelain, nothing will scream "I'm king of the ocean" in your guest bath like this $2995 semi-aquatic conversation piece.

So why is it a gadget? I just like baths It offers chromatherapy lighting. Yeah. Those are special lights that make you feel better (about the whale that was brutally murdered for your bathtub). Who knew? – Mark Wilson

The tub not only has adjustable air massage jets for the ladies (and men), there's also an 8.5-inch LCD with remote control. Besides the 7 jets, 9 bubble jets, and 6 massage jets, it has underwater lights, a super-bass connection, padded headrest, and cable inputs so you can watch DVDs, Cable, or your closed circuit feed to the nanny's bedroom.

Best of all, unlike the other Kosmo, this one won't go around in a blind fury, calling people n*gg**s. – Jason Chen

Yep, it's got it all. Close yourself up in this baby with just your head sticking out, and emerge a while later feeling good as new. Looks like some good clean fun. – Charlie White

Kueco and Visiomatic are making these in wall-mount and free-standing models, available from 10 to 37-inch models. Like we said, if you own your home, you can put these into the walls, but if you rent, the free-standing ones are for you.

No pricing info, but if this is affordable enough, us always-connected bloggers would prefer a waterproof solution than placing our laptops in a large zip-lock bag and hoping it doesn't leak. – Jason Chen

Oh boon Flo, how do we love thee? Let us count the ways. 1) You easily grip onto bathtub faucets, protecting children from hitting themselves on those nasty metal things. 2) You stream the water 12" in front of you into a pleasant waterfall, making it easier to wash children's hair. 3) You store and dispense bubble bath straight into the water. 4) You're so gosh darn cute. We're 27 instead of 7 but we still want you in our bathtub when you come out in May.
