Rectangular Skylights

What size rectangular skylight do I need for my RV?

Measure the outside dimensions of your existing skylight opening, not the dome itself. The most common RV size is 14x22, but rectangular skylights also come in 16x24, 18x26, 22x34, and 24x34 configurations. Check the rough opening on your roof before ordering, and confirm the inside dimensions match your interior trim ring. If you need help matching dimensions to your coach, text or call us at 817-984-1852.

Are these skylights a direct replacement for my existing dome?

Yes, when the outside opening dimensions match. Rectangular RV skylights in this collection are designed as drop-in replacements for the original dome, using the same screw pattern and butyl tape sealing method. Common applications include shower skylights, bathroom vents, and main living-area light wells. For premium-grade replacements with thicker acrylic, see our Icon Premium Skylights collection.

What material are rectangular RV skylights made from?

Most rectangular RV skylights in this collection are thermoformed acrylic, which holds up to UV exposure, hail impact, and temperature swings better than standard plastic. Smoke-tinted and clear options are available depending on how much light you want in the cabin. Pair a new skylight with fresh butyl tape and self-leveling lap sealant for a watertight install.

Do you carry related roof vent and ceiling parts?

Yes. If you are replacing a skylight as part of a larger roof refresh, browse our Ventline Vent essential accessories for matching roof vents, hardware, and trim rings. Ordering vent and skylight components together helps you complete the job in one trip up the ladder.

How much does shipping cost on rectangular skylights?

Rectangular skylights ship via standard ground carrier in protective packaging to prevent dome cracking in transit. Orders over $100 ship free within the contiguous US. If a skylight arrives damaged, contact us within 48 hours of delivery with photos and we will arrange a replacement.
