A cracked RV skylight is one of those problems that announces itself loudly and at the worst possible moment. The first rain after a minor hailstorm, a branch that scrapes across the roof during a campground maneuver, or simply the slow fatigue of plastic that's been cycling between desert heat and mountain cold for ten years — and suddenly you have a water intrusion problem directly above your bathroom, bedroom, or living area. I've repaired enough water damage from failed skylights to say with confidence: replacing a cracked dome before it leaks is always cheaper than repairing the ceiling after it does.
Beyond damage prevention, skylights are one of the most underappreciated features in an RV interior. Natural light from overhead makes a small space feel dramatically more open. A well-placed skylight in a bathroom eliminates the need to run electric lighting during the day. In a bedroom, a clear dome lets you stargaze without leaving your bed — something that never gets old after a clear night in the mountains or desert.
Specialty Recreation makes the majority of replacement skylights sold in the RV market, and for good reason — their products fit the standard opening sizes found in most production RVs, use materials that hold up to UV exposure and temperature extremes, and come in the configurations that matter: single-dome, kit with inner garnish, and multi-pack for rigs with multiple skylights in the same size. The six options below cover every common scenario.
Best for: Replacing the inner garnish on large bathroom or bedroom skylights in rigs with 18" x 30" roof openings where the outer dome is intact but the inner frame is cracked or yellowed
The inner garnish is the white plastic frame you see from inside the RV — the piece that covers the gap between the roof opening and the dome bubble above. It's also the component that takes the most visible UV damage over time because it's exposed to reflected light from the dome above and interior light from below. After eight or ten years, white ABS plastic starts to yellow and can develop hairline cracks around the mounting clips. Replacing just the inner garnish while keeping an intact outer dome is a fraction of the cost of a full replacement.
The 18-by-30-inch size covers the large bathroom skylights that are standard in many fifth wheels and Class A coaches. The dimensions refer to the outer garnish measurement, so verify your existing frame matches before ordering. Installation is a clip-in affair in most cases — the old frame pops out, and the new one snaps into the ceiling opening with the mounting clips that come pre-installed. I've done this replacement in under fifteen minutes on fifth wheels where access to the ceiling was easy. It's the kind of repair that transforms a bathroom from looking tired and dated to looking completely fresh.

Best for: Replacing damaged square skylights in shower stalls, bathrooms, and slide-out ceilings where the smoke tint provides privacy and reduces glare
The smoke black tint on this square skylight is the right choice for bathroom and shower applications where you want natural light without the goldfish-bowl feeling of a clear dome. The tinted acrylic transmits enough light to make the space bright and usable during the day while preventing visibility from outside. This is especially relevant for rigs parked at crowded campgrounds where neighboring RVs might have a sight line to your roof.
The 14-by-14-inch square format is one of the most common skylight opening sizes in travel trailers and fifth wheels, particularly above shower stalls. The Specialty Recreation dome is manufactured from impact-modified acrylic that resists hail, branch impacts, and the thermal expansion and contraction cycles that crack cheaper polycarbonate domes. I've seen smoke-black domes from Specialty Recreation on rigs that are fifteen years old and still holding their shape and tint without crazing or yellowing. The replacement installation requires removing the outer dome, applying new self-adhesive foam tape to the roof flange, and securing it with the original or new fasteners.

Best for: Complete skylight replacement when both the outer dome and inner garnish are damaged or when the existing unit is cracked through and leaking
This is the kit you need when the damage is bad enough that replacing just the outer dome or inner garnish won't solve the problem. Full kit replacements are the right call when the outer dome has cracked completely, when there's water staining on the inner garnish from a past leak, or when the original skylight dates back far enough that mixing old and new components would leave you with mismatched plastic that fits poorly.
Getting both components from the same manufacturer in the same kit ensures the dome and garnish are designed to work together — the dome's flange dimensions match the garnish's mounting profile exactly. I've seen customers buy the outer dome from one supplier and the inner garnish from another and end up with a millimeter of gap they had to seal with caulk, which works but looks sloppy. The Specialty Recreation kit eliminates that problem entirely. It includes everything you need for a clean, complete replacement that looks factory-correct from both inside and outside the RV.

Best for: Budget-conscious replacement of cracked or yellowed inner garnish frames on 14" x 14" square skylights, with ICON as a cost-effective alternative to Specialty Recreation
ICON is a well-established name in RV replacement parts, and their inner garnish for 14-by-14-inch skylights offers solid quality at a price point that's accessible for owners who need to replace multiple garnishes — common on rigs that have been in service for a decade or more and have yellowing across all their skylights simultaneously. The white ABS construction is durable, the clip-in installation is straightforward, and the dimensions are accurate to the standard 14-by-14-inch opening found across a wide range of production RVs.
I recommend the ICON garnish for situations where the outer dome is in good shape and only the interior frame needs freshening. The snap-in mounting system means no tools are required in most cases — you reach up, press the tabs, and the old garnish releases. The new one clicks into place and gives you a bright, clean white frame that makes the interior feel noticeably more maintained. A campground owner I work with replaced every bathroom skylight garnish in his rental fleet with these ICON units and said the interiors looked ten years newer afterward.

Best for: Owners replacing all skylights in a rig at once, or dealers and service shops that maintain fleets with multiple 14" x 22" skylights
Buying skylights in a three-pack makes financial sense for a specific group of owners — those with multiple 14-by-22-inch skylights in the same rig, those who want a spare on hand for the road, and service facilities that do volume work on RV fleets. The 14-by-22-inch rectangle is the most common non-square skylight size in production RVs, found above bathrooms, slide-outs, and master bedrooms in travel trailers and fifth wheels from virtually every major manufacturer.
The economics are straightforward: buying three at the three-pack price versus purchasing them individually saves money if you know you'll use them. For full-timers who have three of these in their rig — say, one above the kitchen area, one in the bathroom, and one in the bedroom — doing a complete refresh all at once means the plastic ages uniformly and everything matches. I've seen rigs where skylights were replaced one at a time over the years, and the mix of tint levels and clarity is genuinely noticeable from inside. The three-pack eliminates that problem.

Best for: Maximizing natural light in living areas and bedrooms, and for stargazing from inside the rig with zero light attenuation
The clear version of the 14-by-22-inch bubble dome is the choice when light transmission is the priority. White domes diffuse light somewhat as it passes through; clear domes let it through at essentially full intensity during the day, and at night, they give you an unobstructed view of the sky from inside. If you've ever lain in a fifth wheel bedroom under a clear dome on a dark night in the desert and looked up at a sky full of stars, you understand why this option exists.
The bubble dome shape serves a structural purpose as well as an aesthetic one. The raised profile sheds water and debris more effectively than a flat dome and has higher impact resistance because the curved shape distributes force across the entire surface rather than concentrating it at a single point. The same acrylic material used in Specialty Recreation's tinted domes means UV resistance and long-term clarity — clear acrylic can yellow over time if it's the wrong formulation, but Specialty Recreation's material holds its transparency through years of sun exposure. A customer who camps in the high desert of New Mexico has a pair of these in his fifth wheel bedroom and says the difference in morning light quality compared to the white domes he replaced is remarkable.

Sizing a replacement skylight requires measuring the roof opening, not the existing dome. The dome is always slightly larger than the opening it covers — that's how the flange seals against the roof. Measure from the inside edge of the curb or opening on the roof, and that measurement is what you use to select the replacement. The most common sizes in production RVs are 14 x 14, 14 x 22, and 18 x 30. If your skylight doesn't match one of these, measure carefully and confirm before ordering.
The inner garnish size is also based on the roof opening, not the dome. Garnishes are sized to fit inside the opening from below, so a 14 x 14 roof opening needs a 14 x 14 garnish, but the outer dome covering that same opening will be slightly larger — usually 17 x 17 or similar. Again, Specialty Recreation products are clearly marked with their intended roof opening size, which eliminates the guesswork.
When installing an outer dome, always use fresh self-adhesive foam tape on the roof flange — never reuse old tape. The foam provides a weathertight seal and absorbs minor surface irregularities. Old, compressed tape is the most common cause of skylight leaks on installations that otherwise look correct. Specialty Recreation includes tape with most of their dome products, and replacements are available separately if needed.
Skylights are a small feature with an outsized impact on how an RV feels to live in. Natural overhead light opens up tight interiors, fresh, clear domes transform the look of a dated ceiling, and a properly sealed skylight keeps water where it belongs — outside. Whether you're doing a targeted repair with a new inner garnish, a complete dome replacement after storm damage, or a full interior refresh with matching new units throughout the rig, the Specialty Recreation lineup covers every scenario.
Don't wait until a cracked dome turns into a leaking dome. Inspect your skylights visually from the roof at least once a year, check the inside garnishes for yellowing and cracking, and replace anything that shows signs of failure. The parts are affordable, and the installation is manageable for any owner with basic tools. Your ceiling will thank you the next time it rains.
