Toto Aquia Dual Flush Toilet

This is a awesome toilet. And it is my favorite 10-inch Rough-in Toilet. It’s unique from the other 10″ models you’ll see around here, because it has a beautiful skirted design with a curved base. The design is a stroke of genius and provides more space for you with its small footprint.
