I really appreciate your enthusiasm. I don’t like either switch, or the two switches I didn’t take a picture of that were at the foot of the tub.
I can just imagine sitting in the tub after putting a dimmer switch in place of the standard switch in case I want a little more romantic mood lighting. So I put a dimmer in there. Yeah, now I can turn it down. So I reach up with lavendar bath salts running down my arm and grab the dial. The water runs down the shaft and ZAAAAP! So much for my mood. (X})
Or, lets look at the switch by the shower stall. It is for the fan. Now I am standing in the bath with water running down my arms. You know you can stand under the shower and get a regular stream of water off your finger tips. I just realized that I forgot to turn the fan on, so I reach around the stall to turn it on. The water, mixed with the more manly Irish Spring that I am using to wash off the lavendar smell, runs down my arm and off my fingers as I grope around the corner for the light switch. After getting the switch thoroughly drenched, I finally find it. ZAAAAP!
Ok, so maybe only a small chance that there will be enough water going inside the switch to make contact. But, I don’t like it.
For this inspection I am going to point out that there are differing opinions about the switch. I was hoping for an honest and for true reference that substantiated the 5’ claim for switch distance from tubs and showers as indicated in the training materials I have. And yes, I know NOT to use those materials as my reference. That is why I am asking the questions. I couldn’t find it in my IRC code and don’t have a copy of the NEC to look it up. And I did find those sections about the hot tub and spas and figured it didn’t apply here. Again, I was hoping someone else could point me to a hard reference.
