Bidet for an RV toilet: what fits, and what to check first

A bidet for an RV toilet is a non-electric attachment that taps the RV's own water line and runs on the water pressure you already have, so no 12V power is needed. It has to fit your toilet's seat bolts, connect to the toilet's water inlet, and work at the lower pressure of an RV pump. RV bidets are sold as complete kits with RV fittings; home bidets can work but often need extra adapters.

We have not tested a bidet in an RV. This page pulls together what RV owners and sellers report, and tells you what to check. Brands and prices below come from listings and reviews, and they change.

How a bidet works on an RV toilet

Traditional bidets are separate fixtures, which an RV has no room for. What RVers install instead is a seat-style attachment. It sits between the bowl and the seat, uses the same bolts as your seat and takes water from the toilet's supply line through a short hose. A knob sets the pressure and a switch or paddle picks the nozzle. Actual force depends on your RV's water pressure, as one RV blogger who installed one says.

There is no electricity involved in the common models, so a bidet does not draw on the house batteries. Listings for these units say they work from the water pressure of the RV's pump or city water, with no wiring or batteries.

Check 1: what toilet do you have?

RV toilets differ from home toilets. Many are small, plastic, foot-pedal models. Some have bowls that are shorter or shaped differently from a house toilet. A few have non-standard mounting. Look for the maker's name on the bowl or the manual. A blogger installed a Clean Camper on a Thetford toilet in a Rockwood Mini Lite in about ten minutes using the same screws and nuts as the toilet seat. Another buyer warns that some RV flanges are non-standard, and one reviewer said they forgot to check toilet compatibility. A question and answer on etrailer about a Tecma toilet shows that for some rigs, there isn't a simple answer, so check with a seller using your toilet's model.

• Seat bolts: are there two bolts at the back, and how far apart are they?
• Room under the seat: will an attachment that is about an inch thick let the seat close?
• Seat type: a molded seat with no bolts is a no.
• Water inlet: where is it, and what size and type of fitting?

For measuring methods, our do bidet attachments fit all toilets page gives the checks for a home toilet; the same bolt spacing, bowl size and clearance steps apply.

Check 2: water pressure from an RV pump

This is where RV and home bidets differ most. A house line delivers a strong, steady flow. An RV's onboard pump is weaker, and when you are on a campground hookup the pressure depends on the campground. One RV guide says some bidet valves are built to work at that low pump pressure while others feel "anemic". A reviewer on a listing said the pressure could be better, but "that is the failing of our RV hookup".

What to look for:

• A pressure knob you can open up fully, so you get all the flow there is.
• Reviews from other RV owners, not house owners.
• A model sold for RVs, since its valve is made for low flow.

If the flow is weak, see bidet water pressure too low for the usual causes, such as a half-closed valve or a clogged screen. And if you're on a strong campground hookup and it is too strong, bidet water pressure too high covers the fix.

Check 3: how it connects, and the shutoff

An RV bidet needs to tee into the toilet's water supply. RV-specific kits include fittings made for RV plumbing. An RV blogger who installed one says home units often need more adapters, which adds leak risk, and that factory RV plumbing may already leak, so extra joints are not free. Home attachments can still work: a T-adapter and a short hose are the same idea. Our attachment install guide and T-valve doesn't fit cover the home version.

Two safety points, from RV owners' write-ups:

• Gravity-fill toilets can overflow. One user added an inline shutoff valve as a safeguard, because a toilet that fills by gravity will simply keep filling if something goes wrong. A shutoff you can close when you leave the rig is cheap insurance.
• Backflow. The Clean Camper reviewed by that blogger has a built-in backflow valve that stops used water from reaching the supply. A bidet is a place where backflow can matter; read do bidets need a backflow preventer and make sure the one you buy has one.
• Plastic threads. A buyer warned against tightening plastic threads fully. Hand tight plus a little, not a wrench crank.

Check 4: the holding tank

RV toilets drain to a holding tank, so people ask whether a bidet helps or hurts. The RV blogger says that using more water and less toilet paper can help the holding tank. We can't verify that, and tank behavior depends on your system. It is also fair to say a bidet uses fresh water, so on a short fresh-water supply or boondocking, it adds to your use. A rinse takes a small amount of water, but track it on your first trip.

Whatever you do, a bidet isn't a license to flush other things. Keep to toilet paper made for RVs and don't flush wipes. See bidet vs wet wipes for why.

RV bidet models people mention

Brands that come up most in RV guides are the Clean Camper, Luxe's Neo series and the Samodra. Prices quoted ranged from about $30 for a basic Luxe Neo 110 to about $165 for the Clean Camper. These are from sellers and blogs, not our testing.

A cheap way to test before you buy

If you aren't sure whether you will like the habit, start with a squeeze bottle for a week. It needs no plumbing and uses a cup or two of water. Note whether you use less toilet paper and whether you like it. If yes, move to an attachment. The test costs about as much as a coffee, and you lose nothing in the rig. See are bidet attachments worth it for the paper math.

Install steps, in order

1. Shut off the RV's water pump, or the city water, and flush to empty the lines.
2. Remove the seat. Keep the bolts; a kit may include its own.
3. Place the attachment over the bolt holes and refit the seat on top.
4. Tee into the toilet's water inlet with the kit's fittings. Keep shop rags ready, since water remains in the lines and makes the nuts slippery.
5. Route the hose so it doesn't kink, and so that the seat can lift.
6. Turn water on slowly. Wipe each joint with dry tissue and check again after an hour and the next morning.
7. Test the spray at the lowest pressure first.

If anything drips later, see bidet leaking from the T-valve and bidet leaking under the seat. Check joints again after a long drive, since vibration loosens fittings.

Winter and storage

If you winterize your RV, a bidet's hose and attachment hold water too. Drain them with the rest of the toilet's water line when you winterize, and check the manual for the maker's advice. We did not find a source that gives a general rule, so follow your RV's guide.

Renting an RV

If the RV is a rental, ask before you change anything. A bottle needs no changes; a removable attachment may be allowed if you put the seat back as it was. See bidet attachment for renters.

Where ASSJET fits

ASSJET is a no-plug attachment: one knob, cold water, about five minutes to put on. We have not tested it in an RV and we are not claiming it fits one. It is for first-timers at home, and it is not on sale yet. If you want to hear when it is, the waitlist is on the quiz.

FAQ

Can you put a bidet on an RV toilet?

Yes, if you have two seat bolts and room under the seat. Non-electric attachments made for RVs run on the RV's water pressure.

Does an RV bidet need power?

The common models do not. They use water pressure, with no wiring or batteries.

Will an RV pump give enough pressure?

Often, but it is lower than a house line. Look for a knob that opens fully, and read reviews from RV owners.

Can I use a home bidet attachment in an RV?

You can, but home kits often need extra adapters, which adds leak risk, according to one RV blogger.

What is the cheapest way to try?

A squeeze bottle with no plumbing, then an attachment if you like it.

Is there a risk of overflow?

Gravity-fill RV toilets can overflow if the line fails, so one user added an inline shutoff valve.
