The last thing you want is a lousy shower.
My wife had enough of our pathetic trickling shower head. Since I prefer to keep her happy, and $50 isn't too much to spend at Lowe's, we installed the new Delta In2ition shower head.
When I say anyone can do this, I MEAN ANYONE CAN DO THIS simple upgrade.
The cool thing about the In2ition is that it has 2 shower heads in 1. There's a hand sprayer that fits into the stationary shower head. This comes in handy when you need to clean your child, a dog, the shower itself, or a dirty & hairy husband (I fall into the first and last categories respectively).
Here are some quick tips
+Always replace the teflon tape but only go down to the last two threads
+Ensure rubber seals are in both ends of the shower hose
+Don't overtighten the shower head to the shower arm
+Brag to your friends about your new showering experience

I also have Delta's video for the In2ition at the end of the post. Let's just say it's probably a PG-13 video clip compared to mine (LOL)
