[Mounting & Placement](https://learn.ogotoilet.com/03-mount-wire-vent?hsLang=en#mounting-placement) # How Far Should the OGO™ ORIGIN Be from the Wall ## And how to properly route your vent hose to the exterior for clean, consistent airflow. If you’re planning to install the OGO™ ORIGIN Compost Toilet tight to the back wall, here’s what you need to know: **Yes, you can install it flush. But for performance, ease of use, and cleaner venting—we recommend leaving space.** This article breaks down **ideal wall clearance**, why it matters, and how to route your **vent hose to the exterior shell vent** based on our floor mounting drawing. --- ### Recommended Clearance from the Wall While the toilet base allows for flush installation, we’ve found that a **2-inch gap between the back of the toilet and the wall** gives you a better fit and function. **Here’s why that 2" space matters:** - **Pushes the toilet bowl slightly backward**, giving you more front clearance for sitting, lifting the lid, or stepping in narrow spaces. - **Allows smoother hose routing**—especially if you're running a vent hose directly out of a wall to an exterior vent. - **Reduces stress on the power jack and hose connection**, both located near the back corner of the unit. So yes, flush is possible—but if you’ve got the space, go with 2 inches off the wall. --- ### Understanding the Rear Layout (Vent + Power) From the **OGO™ ORIGIN base drawing**: - **Vent Hose Connector Height:** ~13" from floor to T-bar center - **Power Jack Height:** ~12.25" from floor - Both are located in the **rear right corner** (by default) - Hose OD: **1.6825"** - Hose End ID: **1.6"**, fits perfectly over **1-1/4" PVC** These low, compact placements make rear venting easy—**if you allow room to route the hose cleanly**. --- ### How to Route the Vent Hose to an Exterior Shell Vent Whether you’re in a van, cabin, or tiny home, routing the vent hose out through the wall is one of the best ways to ensure reliable airflow. **Here’s how:** 1. **Determine your exit point** - Use the floor drawing to locate your base. - Measure **13" up from the floor** and mark your exit spot on the wall behind the toilet. - Add a slight downward angle (ideally 45°) for the hose to direct moisture down and out. 2. **Drill your exit hole** - Use a **1-5/8" hole saw** to drill through the wall. - This fits **1-1/4" PVC pipe** for venting through thick or thin structures. 3. **Mount your OGO™ Exterior Shell Vent** - On thin walls (van or RV): secure directly with bolts through the shell and interior hose flange. - On thick walls (tiny house, wood siding): use a PVC pipe extension through the wall, seated into the shell vent plate. 4. **Connect the hose** - Push one end of the OGO™ vent hose onto the toilet’s T-bar connector. - Attach the other end to the PVC extension or directly into the shell vent, depending on your wall type. 5. **Secure and test** - Ensure there are no kinks in the hose. - Power the unit on—feel for airflow at the exterior vent. If venting into a tight space (like a drawer cabinet), consider upgrading to our **High-CFM Fan** to improve airflow. --- ### Optional Enhancements - **Charcoal Filter**: If venting short distances or into interior cabinets, a charcoal filter can be added to neutralize residual odor. - **Swapping Vent Sides**: Need the vent on the left instead? No problem. You can pop out and switch the fan and filter insert locations. See our [Insert Swap Guide](https://learn.ogotoilet.com/vent-insert-swap?hsLang=en). --- ### Final Word Your install should work with your space—not against it. Leaving just **2 inches of clearance** behind your OGO™ ORIGIN can make a big difference in hose routing, airflow, and comfort. **Measure. Mount. Vent cleanly.** Need help visualizing the cutout or planning around cabinetry? Our support team is here to guide you through the details. - [01.
