The Oxygenics Body Spa Shower Head boasts a more powerful spray with your existing water pressure. We have tested this product in our RV and found that the claims for a more powerful spray were right on! We tested our existing shower head with pump pressure and the spray would barely make it to the opposite shower wall. After installing the Oxygenic Body Spa, the spray reached the opposite wall with almost no drop! Showering with this unit was definitely more like showering with full house pressure at home. If you are tired of weak showers that uses a lot of water just to get the soap off, you will really enjoy this shower head. We did find that when mounted in our RV the head was too high to use in ‘hands free’ mode, so we used a ‘Staytion’ suction cup bracket which allowed us to place the shower head anywhere we wanted without drilling holes or using adhesive.
