Direct replacement polycarbonate bubble skylight for RVs, travel trailers, and fifth wheels. Clear / translucent white — maximum natural light. Outer dimensions 18"×34". Fits all standard 14"×30" rough openings. 4" bubble height. Impact-resistant. Made in the USA.
The ICON 01848 is the clear version of the 18"×34" rectangle skylight — a direct replacement for RVs, travel trailers, and fifth wheels with standard 14"×30" rough openings. The long narrow format is found over shower stalls and bathtubs in larger motorhomes and fifth wheels. Clear tint passes maximum natural daylight — the brightest option for this size and the right choice when full overhead light in the shower or bathroom is preferred.
ICON polycarbonate domes are tested to outperform competitors in impact, UV, and weather exposure. The 18"×34" outer flange covers the 14"×30" opening with a 2" overlap on all sides. Made in the USA, backed by a 1-year limited warranty.

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 01848 Clear 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. 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 before seating the new skylight.
