The system layout was designed by the designer and makes excellent sense. Each flow valve operates the closest fixture.
Below the thermostatic valve operates the tub filler - Dornbracht Water Fall.
To the right the hand held.
To the left the ledgestone water fall
above closest to does the rain head.
Above farest up toes the Gessie vaporizers. These vaporizers are pretty cool - I've never seen them before this job.
