OK, just a word of advice and warning for any of you doing a remodel of your bathroom; particularly the shower.
Be sure there is a slope or slant in your floor, that it slopes towards the drain, which is NOT placed directly under where you stand to shower, and that your flooring within the shower is very grippy/rough/textured, whatever it takes to not be slippery!
Get the valves to turn your water on and to make temperature adjustments set off side so that you don't get wet while adjusting or turning on your water.
Be sure you have a bench or shelf built that is big enough and that will support your weigh AND that it is not directly under the shower head. Ladies, keep leg shaving in mind for this design feature.
OK, that's my twocents!
