Direct replacement polycarbonate bubble skylight for RVs, travel trailers, and fifth wheels. White — maximum natural light. Outer dimensions 18"×34". Fits all standard 14"×30" rough openings. 4" bubble height. Pre-drilled flange. Impact-resistant UV-protected polycarbonate. Made in the USA.
The ICON 01849 is the white version of the 18"×34" rectangle skylight — completing the three-tint family for the 14"×30" opening alongside the clear (01848) and smoke (12117). The long narrow 14"×30" format is found over shower stalls and bathtubs in larger motorhomes and fifth wheels. White tint passes maximum natural daylight — the brightest option for this size, ideal when full overhead light in the shower or bathroom is preferred.
ICON's premium UV-protected polycarbonate resists the brittleness, cracking, and yellowing that afflicts original acrylic skylights over time. The pre-drilled flange simplifies installation alignment, and the engineered flange profile prevents lifting and seal failure at the roof edge. Made in the USA, backed by a 1-year limited warranty.
Maximum natural light transmission through the 14"×30" opening — the brightest option for shower stalls and bath spaces
Long narrow format found over shower stalls and tubs in larger motorhomes — less common size, measure carefully
Resists brittleness, cracking, and yellowing from prolonged UV exposure — outlasts original acrylic domes
Pre-drilled attachment holes with expansion clearance for easy alignment and secure mechanical fastening
Do NOT use self-leveling lap sealant with this skylight. Self-leveling sealants (such as Dicor and similar products) contain chemicals that react with polycarbonate and can cause catastrophic cracking and failure of the dome. Use only a non-self-leveling sealant compatible with polycarbonate — such as butyl tape or a non-self-leveling lap sealant specifically rated for polycarbonate plastic. Sealant is required for installation and is not included with this skylight.
The 14"×30" opening is a less common size found primarily over showers and tubs in larger motorhomes. Measure your actual rough opening carefully before ordering. 1. Rough Opening (Hole Size): Must be 14" L × 30" W 2. Outer Dimension (Flange Size): This skylight is 18" L × 34" W When replacing an existing skylight, also measure the outer flange of the old unit to ensure the new skylight covers any existing sealant marks on the roof.
• (1) ICON 01849 White Rectangle Skylight NOT Included — Required for Installation: • Sealant (must be polycarbonate-compatible — do NOT use self-leveling lap sealant) • Mounting screws
Rough Opening Required: 14" L × 30" W hole in the roof. Pre-Drilled Holes: Flange includes pre-drilled attachment points with expansion clearance — align holes to the roof deck before sealing. Sealant: Use a polycarbonate-compatible, non-self-leveling sealant or butyl tape. Self-leveling sealants will damage the polycarbonate dome. Replacing an Old Skylight: Remove all old sealant from around the roof opening before installing. Ensure the opening is clean, dry, and free of debris.
ICON 01848 — Same 18"×34" rectangle in clear tint ICON 12117 — Same 18"×34" rectangle in smoke tint All three share the same 18"×34" outer flange and fit the same 14"×30" rough opening.
