Residential-height gravity-flush RV toilet with genuine porcelain bowl. Elongated bowl, soft-close seat and cover, ergonomic foot pedal with adjustable water volume, freezable water valve, anti-stick oversized bowl. Fits most RV floor flanges. 36.12 lbs. White. 5-year warranty.
The Invision Voyager 780-0091 is the porcelain-bowl version of InVision's residential-height RV toilet — designed to deliver the comfort and appearance of a home bathroom in any recreational vehicle. The genuine porcelain bowl is the defining upgrade over the plastic-bowl 780-0092: it feels more solid underfoot, cleans more easily, resists staining and odor absorption more effectively, and has the cool, smooth surface that most people associate with a quality toilet.
At residential height — 19 inches from floor to rim — the Voyager eliminates the crouched posture required by many traditional low-profile RV toilets. The elongated bowl shape provides the same seating comfort as a home toilet. A soft-close seat and cover prevent slamming during travel. The gravity flush system runs entirely from the RV's onboard water supply with no electric components required, and the foot pedal's adjustable water volume lets you use just what you need for water conservation. The included freezable water valve allows the toilet to be properly winterized without replacing the valve assembly.
Genuine porcelain construction — easier to clean, resists staining and odor, and delivers the smooth home-toilet feel that plastic bowls can't match
19" rim height matches standard home toilet height — eliminates the cramped low-seat position of traditional RV toilets for all-day comfort
Included freeze-resistant water valve allows proper winterization — protects the toilet plumbing without requiring valve replacement each season
Ergonomic foot pedal with adjustable water flow volume — flush with just enough water to conserve tank capacity at remote campsites
The 780-0091 and 780-0092 are identical Voyager toilets with one difference: the bowl material. Here's what that difference means in practice: Porcelain (780-0091 — this product): • Genuine fired ceramic construction — same material as home toilets • Denser and heavier than plastic — adds solidity and stability • Easier to clean thoroughly — smooth, non-porous surface resists staining and bacterial buildup • Resists odor absorption — doesn't take on smells the way plastic can over time • More scratch-resistant — cleaning products and brushes are less likely to dull the surface • Higher weight: 36.12 lbs vs. approximately 26–28 lbs for the plastic model Plastic (780-0092): • Lighter weight — meaningful if weight reduction is a priority • More impact-resistant — less likely to crack if the toilet is bumped or dropped during installation • Less expensive than the porcelain version • Same gravity flush system, foot pedal, seat, and freezable valve as the 780-0091 For full-time RVers, frequent campers, or anyone replacing a home-like bathroom toilet, the porcelain 780-0091 is the more comfortable long-term choice. The plastic 780-0092 is a practical option when weight savings matter.
Confirm your floor flange is compatible. The 780-0091 uses a two-bolt mounting design compatible with most standard RV floor flanges. Before removing your existing toilet, confirm the floor flange is intact and positioned correctly for the Voyager's bolt pattern. If the flange is cracked, corroded, or positioned at a non-standard rough-in distance, address the flange first. Rough-in distance: Measure the distance from the finished wall behind the toilet to the center of the floor flange before ordering. Standard RV rough-in is typically 10–12 inches. The Voyager's installation guide confirms the required rough-in distance for this model — verify your bathroom will accommodate it before beginning removal of the old toilet. Water supply connection: The Voyager connects to the RV's fresh water supply line at the rear of the toilet base. The freezable water valve connects here. Ensure your existing supply line can reach the connection point with the Voyager positioned on your flange. Weight consideration: At 36.12 lbs, the 780-0091 is significantly heavier than a typical lightweight plastic RV toilet. Two people are recommended for installation to safely position the toilet onto the flange bolts without dropping or shifting.
Tools Needed: Adjustable wrench, channel-lock pliers, utility knife (for old floor seal removal), RV toilet floor seal (purchased separately — required) Two people recommended for lifting and positioning the 36.12-lb porcelain unit onto the flange. Key Installation Steps: 1. Turn off the RV water supply and flush to empty the bowl 2. Remove existing toilet: Disconnect the water supply line at the valve; remove the two hold-down bolts; lift and remove the old toilet 3. Clean the floor flange: Remove and discard the old floor seal and hold-down bolts; clean the flange surface of old sealant and debris 4. Install new floor seal: Place a new RV toilet floor seal (not included — purchase separately) onto the flange; this is the primary waste-line seal 5. Position the Voyager: With a helper, lower the toilet onto the flange, aligning the base holes with the hold-down bolt positions 6. Secure the hold-down bolts: Thread and hand-tighten the nuts onto the hold-down bolts; alternate tightening each side evenly — do not overtighten on porcelain 7. Connect the water supply line to the freezable water valve at the rear of the base 8. Restore water supply and test flush; check for leaks at the supply connection and the base seal Reference the InVision Voyager installation guide included with the toilet or available at invisionrvproducts.com.

Both models share identical flush systems, seat designs, valve configurations, dimensions, and warranty terms. The bowl material is the sole difference — choose based on your priorities for cleanliness, weight, and long-term comfort.
The floor seal (flange seal) is the one required item not included with any RV toilet. Purchase a universal RV toilet floor seal before beginning installation — it's the primary waste-line gasket and must be replaced whenever the toilet is removed and reinstalled.
