The simplest roof vent you can fit. The mushroom vent is a passive, no-wiring ventilation solution that keeps air moving through your van's bathroom, kitchen, or storage areas. The domed cap deflects rain while allowing airflow, the built-in insect screen keeps bugs out, and the screw action closes it tight when you need a full seal.

Benefits:
• Zero wiring required — completely passive ventilation with no battery draw.
• Dome profile deflects rain while allowing constant airflow when open.
• Insect screen built in — ventilate without letting bugs in.
• Screw-action lid seals fully closed for driving rain or storage.
• Compact and low-profile — minimal wind noise and roof intrusion.
• Quick to install — a round hole saw cut and sealant is all that's needed.

Features:
The mushroom vent screws down flat onto your roof surface. The dome shape channels airflow over and around the vent, creating a slight negative pressure inside that draws air out passively — no fan required. Commonly installed above van showers, bathrooms, and kitchens as a secondary vent, or in storage compartments that need airflow without power. Seal the base flange with appropriate roof sealant during installation to prevent water ingress.

For powered ventilation in your main living area, see the Maxxfan Deluxe. For a solar-powered option, see the Vanlifer Solar Roof Vent.

People are asking

What size cutout does the mushroom vent need?

The mushroom vent requires a round cutout — typically 75mm diameter for the standard size. It screws down onto the roof surface with no frame or separate flange required, making it one of the easiest vents to install. Use a hole saw to cut a clean circle through your roof material.

Does the mushroom vent let rain in?

The mushroom dome shape is specifically designed to deflect rain — water runs off the curved cap rather than entering the vent opening. The screw-action closes the vent fully when needed for driving rain or heavy weather. Seal the base flange with appropriate sealant during installation to prevent water ingress around the fitting.

Where in a van is a mushroom vent typically installed?

Mushroom vents are most commonly installed in wet areas — above a shower or bathroom, above a kitchen cooktop, or in storage areas that need passive airflow. They are also used as secondary ventilation points in vans that already have a powered roof fan. Because they require no wiring, they are a simple and cost-effective way to add extra ventilation to any area of the build.
