Here we have a game changer when it comes to water pressure in the rv shower world!  See that little whole toward the bottom of the shower handle?  That oxygenates your shower water to make less water go farther I guess you’d say.  It increases the pressure (we feel by about double) and for those with long hair you can finally get the feeling of a good strong rinse of shampoo and conditioner out of your hair.  Because you’re getting more pressure with less water used your hot water also lasts longer.  We all have found that noone has had to use the “on / off slider” yet while showering to pause the water and lather up and we still don’t run out of hot water. This is yet another splurge I would say as opposed to a true necessity.  But one of the better choices we made.  We weren’t sure if this was a gimmick or not - so we have been truly impressed.
