Design And Installation Concept Of In-wall Tank
!
!
Installation of in-wall tank is much easier and nice-looking comparative to that of traditional tank. Meanwhile, the space
layout will be more reasonable due to the application of in-wall tank pipes and connectors.
The most remarkable advantage of in-wall tank is that the installation will never be limited to certain area, and can be
installed wherever as you wish, which will make the bathroom layout more reasonable and nice-looking, and make good use
of every inch of the bathroom space.
