Mine was caused by the vacuum breaker on the shower hose that connects to the mixer. The water was following the shaft of the valve down the hole it comes out of the cover on the mixer, and filling up the cover until it was high enough to flow into the holes that the water pipes from through the backing board and shower wall. I fixed mine by putting a drain hole at the bottom of the cover and using silicone to block off most of the gap the little gasket misses in the cover hole that the vacuum breaker goes through.
Since you are going to take it apart, I suggest pitting a check valve on your hot water side to prevent the cold blast of water that comes from shutting the shower head off while lathering with soap. I also suggest putting a "no-trickle" valve between the shower hose and the vacuum breaker so you can shut the water off without closing the hot and cold valves (messing up your set temp) or using the trickling shower head shutoff that ends up loading the hose with cold water.
