Convert this shower light to recessed

I've got a light above my shower. I'd like to convert it to a recessed light. Can someone get me started? I've done electrical, just not sure exactly what to get. Above is an insulated attic. Can I use the same box or do I need a deeper box? If so, get a retrofit insulated rated? What about the trim, guessing I need something water resistant? See pics, thanks for help!

 

Replace your existing fixture with a recessed one. Make sure you get one that allows the fixture to be buried in insulation. There are trims specifically for bathroom use that have a rubber gasket to seal out moisture.

 

For most lights there is a box in the ceiling that gets removed and then an old work can is installed for the recessed light.

This is a little different as it appears this is some type of can already.

The only thing you need to know is if the diameter of the hole in the drywall is not greater than what the can requires. approx 6".

Can you further remove the fixture from the ceiling?

 

That looks like a recessed fixture there now, pull that trim down and out, see if there is any mfg. info on it, the big box stores sell a replacement LED trim that does a nice job, suitable for wet locations

Thanks for replies. Here is the rest of the pieces to the puzzle (see attached pictures).

It seems like most replacement trips use the torsion clips on the side. I suppose I can add those to this setup using these?:

If I don't want to to use those, does progressive lighting have their own torsion system to keep the trim attached using that metal clip attached to the top of the can? If I want to use that, I guess I am limited to the progressive lighting trims, and would have to go with something from here:

Just a little confused on which route to take, looking for a little advise as I have a lot of lights with the same setup that I am looking to replace the trim on.

 

Progress Lighting can.... P87AT (air tight)

 

So I have to stick to the progress lighting trim I am guessing? There system seems proprietary with none of the LED retrofits wanting to work with it without some modification clips I posted earlier.

 

You could contact Progress lighting customer service and have them suggest a trim.

There are many retrofit LED trims that have springs that grip onto the can housing. No special clips needed.

I've never had good luck with those retrofit clips. They don't seem to hold the light firm against the ceiling.

Thanks for all the suggestions. I ordered some progress lighting trims, I will report back after getting them in!
