Recessed Lighting above shower


Are there any electrical codes that would prevent me from installing a recessed light above my shower? Is there a specific type of trim I would need to buy for use in damp conditions?

I can't be sure about how high the ceiling needs to be above the shower (someone will chime in about that soon).

Yes, there are special trims for shower locations. Examples:
http://www.junolighting.com/product_...d=1740&brand=1
http://www.junolighting.com/product_...d=1742&brand=1

Make sure you find out if a shower trim is available with the particular recessed housing you're looking at. Not all housings have compatible shower trims. My electrician prefers Juno recessed housings.

Good luck

Recessed Lighting above shower


I found this on the interweb (http://www.mikeholt.com/newsletters....y&letterID=397) which states that the luminaire zone doesn't apply to recessed lighting. Is this correct? Could I install a normal recessed light above the shower?

I have seen the shower trim lights and do not like the appearance of them.

Your local codes will override anything else. Maybe talk to your local inspector or building code department. For everything I've seen, you MUST have a shower trim over a recessed light within a tub/shower enclosure with an 8' ceiling. Doesn't really matter how it looks, your goal is not to have anyone electrocute themselves.

The light should be rated for the said moisture level. I think >= IP65 or maybe >= IP55 is whats needed

The graphic you posted is excellent. As it shows, you can install a recessed light in the ceiling above your shower. The article further states:

Luminaires located in bathtub and shower zone must be listed for damp locations, or listed for wet locations where subject to shower spray.


Normally in the ceiling, the damp location fixture is acceptable.

Any local hardware store that sells recessed lighting should also have a cover rated for over the shower or wet location use. The one in my basement bathroom is basically a simple all plastic cover.

Ash, just a forewarning, don't link to wikipedia articles on the forums here, its highly frowned upon here...

I have a comment with the type for bath room: if it is recessed in the ceiling you just need the luminaires with have glass cover or prismatic cover and it must be:
-Minimum IP 54= Splash-proof (Splashing water from any direction shall have no harmful effect)
-IP 65 = Jet-proof (Water protected by a nozzle from any direction shall have no harmful effect (Nozzle diameter 6.3 mm, pressure 30 kPa)
-Max IP 66 = Jet-proof (Nozzle diameter 12.5 mm, Pressure 100kPa)
-And I think no need to choose greater IP because it is so expensive.
Ofcouse we need a RCCB for this line.

Minh is located in VietNam and I suspect it was supposed to be RCD which stands for Residual Current Device basically its equivalent to our GFCI Ground Fault Circuit Interrupter. I may be wrong but I don't believe its required by the NEC to put the bathroom lighting on a GFCI, though because this is above a shower it might be. Someone else will chime in I am sure and give their opinion or state some code here....

You are correct theat. Unless the manufacturer requires the GFCI, and some do for their shower lights. But the NEC does not.

Ah, right forgot that little bit about "if the manufacturer requires it" Thanks John.

I have seen some installs were a DIY'er (I assume) had run the power into the GFCI and then out to the lights and fan so that the whole bathroom is protected by the GFCI outlet. Problem is if the GFCI trips for some reason, your completely in the dark (unless you happen to have a window in your bathroom). Most often a GFCI will trip on something that is plugged into the outlet, not from a light or fan (though it is possible, but rare).

Dear all,
First of all I really sorry because I typed a mistake word in last message: "comment..". My idea is "recommend ..." .

RCCB (Residual Current Circuit Breaker) is the same meaning RCD.
"High sensitivity 30 mA RCD (for example differential load switch type ID’clic) on
circuits to bathrooms, shower rooms, laundry rooms, etc. (lighting, heating, socket
outlets)"
This is suitable with IEC 60364-7. I intend attached the file for you but it is bigger size than max size of attached file. How can I send it for you cooper 4x4?

Some of the stuff in these documents looks like a specification for a chastity belt.
