What size RV toilet do I need for my camper?

Measure the rough-in distance from the wall to the center of the floor flange, then check the bowl height and overall footprint against your existing toilet. Most RV toilets fall into low-profile (around 14 inches) or standard height (around 18 inches) bowl ranges. Confirm your floor flange bolt pattern before ordering. If you need to refresh other bathroom plumbing components at the same time, the Thetford holding tank chemical lineup covers odor and waste breakdown for the system you are connecting to.

Are porcelain RV toilets worth it over plastic?

Porcelain bowls resist staining and scratching better than plastic, hold up to repeated cleaning chemicals, and feel closer to a residential toilet. Plastic bowls are lighter and cheaper to ship, which matters for slide-in campers and smaller travel trailers where weight is a factor. For full-timers and frequent users, porcelain is the longer-lasting choice. Plastic still works well for occasional weekend use.

How hard is it to replace an RV toilet yourself?

Replacing an RV toilet is one of the more straightforward DIY jobs on a camper. Shut off the water supply, flush to drain the line, disconnect the water inlet, remove the two floor bolts, and lift the old unit off the flange. There is no wax ring required like a residential install, just the bowl seal that comes with the new toilet. Most owners finish the swap in under an hour with basic hand tools.

Will a new RV toilet fit my existing floor flange?

Most RV toilets from Dometic, Thetford, and Sealand use a standard 4-bolt or 2-bolt floor flange pattern, but the bolt spacing and water inlet location vary by model. Pull your current toilet first or check the manufacturer label underneath to confirm the flange spec. If you are also replacing waste tank treatment supplies during the install, the Thetford tank chemical collection stocks the deodorizers and waste digesters that pair with these toilets.
