Here you can see the dome skylight that's above the soaking tub and how the round wall extrudes from the wall opening up the bathroom with more space. The Oasis Model ATU Tiny Home Exterior in White and Green. Tiny Home on Wheels. Hawaii getaway. 8x24' trailer. I love working with clients that have ideas that I have been waiting to bring to life. All of the owner requests were things I had been wanting to try in an Oasis model. The table and seating area in the circle window bump out that normally had a bar spanning the window; the round tub with the rounded tiled wall instead of a typical angled corner shower; an extended loft making a big semi circle window possible that follows the already curved roof. These were all ideas that I just loved and was happy to figure out. I love how different each unit can turn out to fit someones personality. The Oasis model is known for its giant round window and shower bump-out as well as 3 roof sections (one of which is curved). The Oasis is built on an 8x24' trailer. We build these tiny homes on the Big Island of Hawaii and ship them throughout the Hawaiian Islands.
