Be careful in buying these shower systems. 
If it says it has an anti scald cartridge...really means it only puts out very warm water.
We fully installed it, tile on one side, dry wall on the other. And it wont produce a nice steamy shower or bath. We turned up the adjuster to the hottest.
Thankfully Wayfair refunded the money and the manufacturer is sending us a cartridge with no limiter. Fingers crossed!
Otherwise everything is spot on
