¨Installation of in-wall tank is much easier and nicelooking 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 nicelooking,
and make good use of every inch of th bathroom space.
