1. Site conditions
Prevent unnecessary purchases of unsuitable products by checking the site first. One thing to look out for is water pressure so you can determine the size of the overhead shower. This way, you can ensure optimal performance of the products you will install.
Another important factor is the existing shower connections. Are the hot and cold water connections exposed in the bathroom? If yes, it would mean that installing the beautiful overhead shower would likely require the hacking of walls, which may not be ideal for you. The wiser choice would be installing a showerpipe system which combines an overhead shower and a handshower.
