The Sub-Tub is a rather strange product. It’s a concept apparently and as far as the design goes, it's certainly interesting with a whirlpool tub, sink, and OLED display all rolled into one. The design would also clearly be very expensive if it were produced aiming at rich folk.
The weird part is that it's designed for the rich, with small space. Those two things just don’t go together. I guess it would be great for the mountain cabin or something. At any rate, the device has whirlpool jets and a built in sink and the lid folds down when not in use to hide the tub.
The OLED screen strangely has no TV tuner it seems, you can upload pictures to view if you want. I'd rather have the ability to view movies or other video. The whole thing is cool, even if it looks a bit short and shallow for tall folks to stretch out.
