WHY WALL HUNG?
Clean in form and function! - great design goes with functional improvement: forget cleaning those uncomfortable nooks and crannies under and behind your traditional toilet (Yuck!)
Save space!- hiding the water tank in wall gives you all that extra room ( yet one less item to clean - phew!)
Eco-friendly! - the tank has a water saving feature built in - save environment and save some bucks!
Discrete sophistication! - that design again! put your toilet in a spotlight - no need to hide it in a shadow!
