A lot of these showerheads will require no tools for their installation. If you’re replacing the existing fitting, then it should take only a few minutes. That being said, it’s always important to check if the manufacturer specified whether some tools are required. If you want to change the plumbing on showerhead, then this would be another matter. To change from a wall-mounted head to a ceiling-mounted one, you will require extra piping. For those looking for the simplest method of mounting a showerhead, then look for one that is a straight swap with your existing model.
