Bathroom Skylight Mods

We like the light that the bathroom skylight brings into the RV, but hate the accompanying heat. I've been thinking about how to remedy this problem somewhat for quite a while now.

I've noticed that our vent fans do let light in but not the additional heat. Our fans have a shroud covering them. I realize that with so many different designs of bathroom skylights, that a shroud is not possible. However, I think there is something simple that may be possible. Bear with me here.

I am thinking about purchasing a replacement skylight to mount above the current skylight. I would remove the existing screws and then using longer screws and some type of spacer, such as ferrules, so that the second skylight sits 1/4" to 3/8" above the regular skylight. I would then drill some small holes in the second skylight to let both heat and air escape and not be trapped in between the two skylights. I am not trying to make a double walled skylight, just trying to find a simple way to dissipate the heat and still let the light in.

Has anyone done something like this before? If so what are your results?
May your smiles be many and the miles be plenty.

Any chance you can put something like window tint on to reflect the heat, but still allow light in?

I layered a sheet of window tint between the skylight and the bubble top. Worked great.

When my clear one got cracked, I put a new smoke sky light in and it does not seem as hot as the old one. Still plenty of light gets in.

1. From screw to screw I put in a small bungy cord on the skylight opening in the shower.
2. When we travel I put a pillow in the opening and no heat comes in.
3. I also painted the outside with white paint.

The pillow helps out a lot.

I painted mine with flex seal. 2 coats of white, then 2 coats of black and 2 more coats of white. I don't like light in the camper. However with 2 or 3 coats of just white it will still let light in and keep the heat out. Hopefully it will also protect it from hail and uv lights.

Bathroom Skylight Mods

I got tired of them as well. Bought a sewing machine and made covers for the inside to keep the heat out. They also keep the light out as well.

First set was expensive since we didn’t have the sewing machine but they work great and now I know how to use a sewing machine

Used Velcro command strips to keep in place so they are still removable if we want. Second season and still working well.

Mesh window covering will let light in but will block some heat. You can snap it or velcro it to the inside.

I taped white copy paper to the inside of the shower dome.

Has been on there 2 years now and cuts the sun 80%, but still enough light to see things.

I painted all skylights with white plastic paint from home depot. It cuts heat tremendously.

We made a custom inside cover out of beige colored blackout material and attached it with Velcro. When some light was needed we peeled open a corner.

I went up on the roof and used a can of rustolium plastic paint and painted mine white. It still lets in a little light, but what a BIG difference is heat...

I used 4 command strips on the ceiling to hold magnets. Cut a piece of reflectix slightly larger than the skylight and use 4 magnets to hold it in place. When I want to move it, just pull off the magnets, the ones on the command strips stay there. Bathroom stays a bit darker and a lot cooler.

Remove the inner dome and put clear bubble wrap in the space between the two domes...
