shower skylight dome

I removed my outer shower skylight dome to replace it before it leaves inside storage this spring. The outer flange measures 18.25x16.25. I'm having a hard time finding the same size online or at closest rv dealer. Is this a Sunline specific size or does anybody know where to buy one?

I'll post on Saturday. I'm in search of one too. Mine is mostly just like yours only being 1 model year apart.

I have found many places that sell them, just did not go out and measure mine yet. Will do on Saturday and be back to compare notes.

Prices seem to range all over. And then there is the type of plastic.

Be back soon

John

Folks.....

Just a thought for after you install the new one......


I don't much care for the excessive heat build-up from the sun's infiltration through the clear dome. On my last few trailers, I've used plastic-friendly satin white spray paint outside to cover the dome and flange out over the caulk.


The shower area stays bright but not overly hot, and I discovered that an unplanned benefit was that the previously-clear dome and the caulk do not deteriorate.

We bought a new one for our 2553 on Ebay last spring. It was perfect.

Hi Rod,

Let's compare notes.

Your skylight and mine are different sizes. You "might" have the smaller shower. In the models years of yours, mine and maybe all the way to the 2007's they had at least 2 size showers.

My 2004 T310SR and my 2004 T2499 had the bigger shower. 36 x 23 1/2"

I know the 2005 T280SR and the 2007 T286SR had the smaller shower. I think it might be the 30 x 23 1/2"

What is your shower size?

I have Eternabonded my shower dome outside flange so right now I cannot get to the outer flange, but I can get the inside.

My inside wood opening size and the inside bubble size is 22 1/4" x 14 3/4" x a 4 1/4" inside high bubble size from the mounting surface.

From my research the outside flange "might" be 1 1/2" wide on the sides.

If it is, then the outside flange would be 25 1/4" x 17 3/4" as opposed to your 18.25x16.25.

Here are the places I have found. There seem to be 2 types of plastic, Polycarbonate (Lexan) or acrylic (Plexiglas). By the way mine cracked I'm guessing mine is acrylic. However Polycarbonate has been known to have spider cracks around too tight of a screw or bolts. And a running long crack in is more prone to acrylic than polycarbonate as a general statement from my plastics background.

EZTops - This place sells polycarbonate domes that come close to my size. I do not know if the 1/4" increments fall into the next even nominal size. May have to call them. The white one are warranted for 5 years against UV which is the only warranty I have found. However the bubble height is less. For me I would be looking at an inside bubble size of theirs as a 15 x 22 x 3 high against my 22 1/4" x 14 3/4" x a 4 1/4" high

http://www.eztopsworldwide.com/rvskylights.htm

Pellandent
- Here is another place. These are polycarbonate. The outer flange is a little bigger, maybe, the inside a little less, the height is taller. Cost is close to 2x. They include a tube a urethane caulk that has to be used.
Skylights - Replacement Domes

14 x 22 White Outer Dome SL1422W

White
Rough Hole Opening Size- 14" x 22"
Flange-Flange Size- 17.5" x 25.5"
Height- 5"
Double Dome, order part # N1422D

This one is taller and a a little smaller inside
As opposed to my 22 1/4" x 14 3/4" x a 4 1/4" inside high bubble size.


Bri Rus brand. These are polycarbonate and come in sizes like the Pellendant. They also include a tube of caulk.

BRI-RUS Specialty Recreation

They can be bought here as one place. Price is not that bad and shipping may be cheaper. They seem to be on sale now.
RV Replacement Skylights from Bri-Rus - PPL Motor Homes


Aia Industries - These guys state they will custom make every one. Do not know what the materiel is.

RV Skylights, Replacement Domes for RV's - AIA Skylights

Icon Direct - This factory is in Canada. I have bought my AC shroud from them. They have polycarbonate and the company has good quality. Does not say about the caulk we need to use. And they seem to have the size that will fit mine just not the exact 1/4" size. The height is right. The price is in line. Freight, there is no issue importing, they handle all that, shows up Fed Ex if I recall right. They did not list a warranty, they did on my AC shroud which was a lifetime.

Skylights | Sky light Domes | RV Skylight Replacements

For me they offer a
RV Skylight | Roof Dome | SL1422

Fits all standard 14” x 22” skylight openings.
  • Dome Dimension: 14" x 22" x 4"
  • Outer Dimension: 18" x 26"
As opposed to my 22 1/4" x 14 3/4" x a 4 1/4" inside dims and height of bubble size. While the inside is a little less on the 14" the outside seems to make up for it.


What I do not know is what is industry standard on the size? I'm measuring 1/4 inches which may be inside the nominal size. The outer flanges seem to range from 1.5 inches to 2". The need is the outer flange has good coverage to create the seal. If the inside is a little smaller will not affect the operation. As far as warranty I have only found the one place that states what it is. Polycarbonate when bought on the vent hatches comes with a better warranty than the acrylic from what I have found.

I will have to research or call about the sealant to make sure it is compatible with the rubber roof and the dome plastics. Before researching this where some come with a urethane sealant, I was thinking they used butyl sealing tape. But maybe not. Have to find that out.

Hope this helps. Let us know how you make out. I will pass along anything I hear. I will try to start calling places this week.

John

Bobby, do you have a site you bought it from and when you listed yours up, what type of caulk did Sunline use? Butyl sealing tape or something else?

Hi Frank,

Thanks for the heads up. Ours is a frosted white to start with. I have seen clear on some of the new campers out now. I have heard in the real hot climates, FLA or AZ for example, some folks have said they upgraded to the smoked tint to help block out the sun from cooking the shower.

And then there is the inside steam dome. The clear ones have a different inside setup. Our Sunline has a frosted white thin inside steam dome. The roof dome is up above that.

At this point I was going to stay with the frosted white which seems to align with your experience too.

Thanks for the heads up

John

Thanks John for all your research and everybody for all the comments and ideas this forum is great!

My bad, the outside measurements are actually 26.25 x 18.25 x 4.25, I typed it wrong. I measured my tub area yesterday and it is also about 2' x 3', My inside opening seems about the same as yours Jon I measured about 22.5 by 14.75, The flange seems to be just under 2", I think we have the same dome John. Not sure on material but my old forest river had thicker plastic on dome that cracked right away around the screws making plastic type fingers or strips around the flange that warped and pushed up through the sealant, don't want that kind again! It looks like the Sunline dome had butyl tape on bottom of flange and rubber roof sealant on top, it seemed to work so I'll probably go with that again.

I'll probably start calling around and order one today.

Thanks Again Everybody!

I called and ordered a white one from EZ TOPS $93.06 incl shipping. They said the inside hole would be 15x23 and the outside would be trimmed to 18.25 x 16.25. Also they said they could get one for me thats 4" high. 2 weeks shipping though

Thanks Again!

Rod,

Thanks for reporting back. Been tied up at work and have not made it to calling.

Thanks for confirming the size. Now I have an idea of the outside flange area.

Take pics of yours before and after and where the crack started if you can and post when changing it.

Thanks

John
