The Flow Max is Lippert's full-residential-feel RV toilet built for daily use on the road. An 18-inch seat height, fully enclosed flush rim, and soft-close seat-and-lid combo deliver a home bathroom experience in a lightweight, water-efficient package that installs with a standard 3-inch floor flange.
Most OEM RV toilets are short, noisy, and designed around cost rather than comfort. The Lippert Flow Max changes that. At 18 inches of seat height -- matching a standard residential ADA-style toilet -- it eliminates the low-squat awkward posture common to older RV bath setups. The round white bowl is molded from durable lightweight plastic that keeps total weight at just 8.1 lbs, making it easy to handle during installation and easy on your floor structure year-round.
The gravity-flush system uses a foot pedal mounted at the base: a partial press adds fresh water to the bowl, a full press triggers a complete gravity flush with full-bowl coverage. One pint of water is all it takes per flush cycle, making the Flow Max an excellent choice for dry camping, boondocking, or any trip where fresh water tank capacity matters.
Hydraulic hinges lower the seat and lid gently every time -- no slamming, no cracks, no middle-of-the-night noise.
The fully enclosed rim directs water around the entire bowl perimeter with every flush, reducing splashback and improving hygiene.
Hands-free two-stage pedal: partial press fills the bowl, full press activates the flush. Clean and intuitive.
Uses approximately 1 pint (0.5 L) per flush -- critical for boondockers and full-timers managing fresh water supply.
The Flow Max mounts to a standard 3-inch RV floor flange with the included T-bolts, nuts, washers, and mounting caps. Floor material in the flange area must be between 1/4 inch and 7/16 inch (6-11 mm) thick. The water supply connects via a 1/2-inch NPT fitting at the base -- compatible with the standard flexible supply line found in most RV bathrooms. No special tools or custom adapters are required for a typical swap-out installation.
The removable lid lifts off entirely for deep cleaning access around the hinge area and bowl rim. Use RV-safe toilet bowl cleaners and a soft brush -- avoid abrasive pads or household bleach-based cleaners that can degrade plastic over time. The enclosed rim design reduces hard-to-reach buildup compared to open-rim toilets.
At 1 pint per flush, a 40-gallon fresh water tank gives you roughly 320 flushes before refill -- significantly more than older 1-gallon-per-flush RV toilets. For full-timers or extended off-grid trips, this efficiency adds up fast. The lightweight plastic construction also adds no meaningful stress to slideout bathroom floors common in modern fifth wheels and travel trailers.
