Re: Wall sconces over tub
This topic has been covered before on this forum, you may want to perform a search for it.
The code does appear to not limit the installation of a surface mounted fixture, be it on a wall or ceiling from being in a bathtub or shower area.
I personaly think there is real hazard potential, and would prefer not to install any type of electrical equipment within the zone specified in 410.4(D).
The homeowner/designer should be made aware of the dangers involved, and GFCI protection should at least be figured into the circuit.
