22 in x 22 in RV Skylight Replacement Outer Dome - Clear RV Cover

In this review of the 22 in x 22 in RV skylight replacement outer dome, the bottom line is simple: this is a practical, durable option for RV owners who need a direct-fit outer cover that brightens the interior while standing up to weather. The reviewer found it ideal for replacing a worn or cracked outer dome on standard 22 in x 22 in skylight openings, and the largest reason to buy is the thicker polycarbonate construction with UV coating that balances light transmission and long-term durability.

Key Features

• Fit: The outer cover measures 26 in x 26 in and is sized to fit most 22 in x 22 in skylight openings, giving a generous flange for secure mounting.
• Durable construction: Made from thicker polycarbonate, the dome resists impact and high temperatures so it lasts in outdoor conditions.
• UV protection: A surface UV coating reduces interior fading and heat gain while preserving natural light.
• Light transmission: The clear option lets ample daylight into showers, bathrooms, and living areas to improve interior ambience.
• Ease of installation: Pre drilled holes and a lightweight dome make installation simpler and safer than glass replacements.
• Weather resistance: A wide roof flange helps the unit resist wind uplift and provides a solid sealing surface.

Who It's For

This skylight outer dome is aimed at RV owners, campers, and motorhome users who have an existing 22 in x 22 in interior opening and want a straightforward, direct replacement that increases daylight and resists weather. It is especially useful for shower and bathroom areas where a clear cover brings extra light.

Those who need a specific tinted option or a taller dome profile should check other size or color choices before buying, and buyers who require an inner venting lid or integrated screen may prefer a complete skylight assembly rather than a single outer cover.

Pros & Cons

Pros

• Thicker polycarbonate construction offers clear durability and impact resistance for outdoor use.
• Pre drilled holes and lightweight design make installation quicker and safer than glass alternatives, improving ease of installation.
• The large 26 in flange provides good sealing surface and wind resistance, supporting long-term functionality.
• Comes in clear and multiple colors so owners can choose more light or more heat filtering for comfort.

Cons

• Some customers report the dome profile is shorter than expected, so those needing a taller dome should verify fit before purchase.
• As an outer cover only, it does not include an inner vent or screen, so additional parts may be needed for a full skylight replacement.

Specifications

Our Verdict

The 22 in x 22 in RV skylight outer dome is a solid, value-focused replacement for standard skylight openings; its thicker polycarbonate and UV coating make it a sensible choice for owners who want more light and weather resistance without replacing the full skylight assembly. Buy this if you need a durable outer cover that installs easily and brightens the interior; look elsewhere if you need a taller dome or an integrated inner vent.
