White standard-height Dometic RV gravity-flush toilet with lightweight plastic construction, residential-style seat comfort, soft-close seat and lid, spray-flush operation, and compact 2-bolt replacement design.
The Dometic 9610008275 400 Essential is a white standard-height RV toilet designed as a compact gravity-flush replacement for compatible RVs, campers, travel trailers, fifth wheels, and motorhomes. It uses a lightweight plastic construction that helps reduce overall RV weight while still providing a full-size residential-style seating experience.
This model is part of Dometic’s newer Essential toilet lineup and is commonly positioned as a simple replacement or upgrade option for older Dometic 300 and 400 Series toilets, as well as many competitor RV toilets. Its short rough-in requirement and 2-bolt mount design help simplify installation in tight RV bathrooms when measurements match.

Dometic part number 9610008275 is listed as the 400 Essential / GV400 white standard-height toilet. If replacing an older Dometic 300 Series toilet, compare dimensions, rough-in, water line location, floor flange, and bathroom clearance before ordering. This is a gravity-flush RV toilet. It is not a macerating toilet, cassette toilet, composting toilet, portable toilet, or residential home toilet.
Before Starting: Shut off the RV water supply, turn off the water pump and city water connection, relieve pressure, and drain the toilet water line before removing the old toilet. Wear gloves and follow sanitation procedures around the floor flange and holding tank opening. Basic Installation Steps: 1. Confirm Fitment: Measure rough-in, rear wall clearance, side clearance, front clearance, water line location, and old toilet footprint. 2. Turn Off Water: Shut off the RV water pump and city water supply, then flush to relieve pressure. 3. Disconnect Water Line: Carefully disconnect the water supply from the existing toilet. 4. Remove Existing Toilet: Remove mounting hardware and lift the old toilet off the floor flange. 5. Inspect Flange and Floor: Check the floor flange, mounting bolts, seal surface, and surrounding floor for cracks, leaks, softness, or damage. 6. Install New Seal: Use the correct RV toilet floor seal or gasket for the installation. Replace old or compressed seals. 7. Position Toilet: Set the toilet evenly over the floor flange without shifting or damaging the seal. 8. Tighten Evenly: Secure mounting hardware evenly without overtightening, as plastic bases and RV flanges can crack. 9. Reconnect Water: Attach the RV water supply line and verify proper seating at the connection. 10. Test Operation: Restore water pressure, test the foot pedal flush, inspect for leaks, and confirm the bowl seal holds water.

Match this toilet by part number, toilet type, floor flange, rough-in, rear clearance, side clearance, seat height, water line location, and service access. Do not select by color or general appearance alone.
If toilet issues continue after installation, check water pressure, supply line fittings, flange seal, mounting hardware, flush ball seal, bathroom clearance, and floor condition before replacing additional components.
This toilet is intended for compatible RV gravity-flush sanitation systems only. Do not overtighten mounting hardware or water fittings, as damage or leaks may occur. Always shut off water pressure before installation or service, use proper sanitation procedures around the floor flange and holding tank opening, and winterize the toilet according to manufacturer and RV plumbing requirements when freezing temperatures are possible.
