Is your inside shower head still stock. If it is this might be a good time to consider an upgrade and move the existing shower head to your outside shower. Just a thought.
Some, including me, have switched to the Oxygenics BodySpa shower head with great results. Note: If you do consider the BodySpa make sure you get the model with the shut-off. I unfortunately didn't have this foresight when I purchased mine.
