Re: bathroom lighting
Bryan,
    I don't think that 410.4(D) prohibits wall hung fixtures in the tub area.  I think that it should, but I don't think that it does.  It is all based on what a "hanging fixture" is.  Is a wall hung fixture a "hanging fixture"?  I think that this was addressed in a ROP but I don't remember exactaly when. 
    If this was a hot tub, then 680.43(B) would prohibit the installation.  As long as it is a hydromassage bathtub, then 410.4(D) applies.
