The Model S 20″ height bowl toilets are produced by a large manufacturing plant in Shenzhen, China. The factory has been operating for a decade and is known to provide high quality products. While the Convenient Height uses this large plant, our production line is occupying a small portion of this facility to make the Model S toilets. And since the sizes of 20″ bowl are the first, there is a lot of hand made work involved and this adds a lot more time to the process. As soon as we involve more automation to this new production line, our capacity and speed will grow.
