Porthole Bungs
Our range of porthole bungs
Blackout, opaque, frosted, and transparent porthole bungs. Made from cast acrylic with a soft rubber edge. Available in various colours. Sizes from 11" to 19".
Blackout Range
Our blackout porthole bungs are perfect for complete darkness and privacy; effectively blocking out external light, ensuring uninterrupted darkness onboard.
Opaque Range
Striking the balance between privacy and natural light. These bungs allow enough sunlight through to create a vibrant glow while blocking the view from outside.
Frosted Range
Semi-transparent porthole bungs with a slightly textured surface. Natural light filters through and disperses beautifully, casting a soft glow throughout your narrowboat.
Transparent Range
Our transparent porthole bungs allow you to maintain a clear and unobstructed view of the surrounding waterways.
