In Japan, everything is constantly being improved, it seems. They're never happy with whatever the current version of their things is, so they need to upgrade, upgrade, upgrade! And while bathtubs might seem like they're doing OK as-is, these hot-rod baths certainly do take the humble bathroom appliance to the next level.

Looking like either a gigantic glass pipe or some sort of frozen iTunes visualization, these are sculpted from fiber-reinforced plastic and "painted with colorful, fluid patterns meant to evoke a sense of speed." And sure, spending $26,000 on a bathtub might seem like a lot, how else are you going to upgrade away from the boring old bathtub you have now? — Adam Frucci
