未使用時には壁に収納される換気扇だそうです。
Exhaust fans in bathrooms are a necessary evil that many interior designers struggle with. There is a way to make them invisible and completely disappear when not in use. Venti appears to be a regular tile on the outside, but is in fact a fan! Simply pop it open when you need it. Intuitive and functional is what I like to call it.
使っていない時には見えなくなる換気扇。とは、考えたこともなかったですね。
換気扇は、そこにあって当然。なるほど、これは面白いアイデアですね。
