Homemade Light Blocker For A Shower Skylight Vent Made From Aluminum J Channel

Blocking the heat and light that comes into your RV’s bathroom through the skylight can be a challenge. Wadcutter on the RV.net forums found an innovative (and cheap!) solution. Here’s what he did,

I got some aluminum J channel that’s used for aluminum siding. Cut it to fit on 3 sides around the shower dome and held in place by the same screws that hold the dome. Round the exposed ends to eliminate the sharp points. This creates a slot. I then cut some white paneling to fit in the slot. When I need shade the paneling just slides in. Being white it matches the color of the ceiling. When you want light then remove the siding and it easily stores under the mattress. The channel holds it snug enough that the paneling won’t move when going down the road. I made similar for the overhead vent in the bedroom.

While he used aluminum J channel to hold the section of paneling, you could also use plastic J channel and expect similar results.

Plastic J channel should work just as well. I had aluminum left over from a siding project so just used what was laying around. If I didn’t have any on hand I’d go with plastic J channel.

The paneling blocks the majority of the light, but some still peeks through the gap at the ceiling.

Here’s what the makeshift skylight cover looks like without the panel in place.

Blends in nicely. You’d think it was put there at the factory!

While it’s not insulated it will cut the heat coming in too. When the cover isn’t being used it doesn’t take up any space to store it.
