I checked ebay out and that pump does appear to be a well pump. There is nothing wrong with that but wells are often deep enough that their pumping solutions are on the high lift/low flow end of the spectrum. Pumping water from a tank at ground level for your shower is more in the middle of the range. I used this ShurFlo pump before I upgraded:

One thing to remember is that while it says 3.0 gpm and 55 psi on the box that really means 3.0 gpm at a very low pressure and 55 psi at a very low flow. You DO NOT GET 3 gpm at 55 psi. Therefor I think you will be disappointed when you try to take a shower with this supposedly 1.6 gpm pump as it will put out less than 1.6 gpm under most conditions. As for using a submersible pump in a catchment tank, many people do. I considered doing so myself.
