External shower taps are distinguished from the built-in because they are immediately visible and we can touch them. You indeed note both ways, hot and cold, which are above the lever for checking water jet. Choosing an external shower tap is the most practical solution when we don’t have particular needs in terms of space and when aesthetic of the interior part of the shower is not damaged by this installation. The procedure is pretty standard, with the pipes which have similar attacks in every plant. The attack could from below, or spilled. This last allows the installation directly under the shower pillar.
