Motorhome bathrooms work in another way from ones in a house- and boy, don’t we all know it! All the things you set into the bathroom is saved in a holding tank, which then must be emptied afterward.
That is often known as the black water or black waste tank… even when it’s a brownish cartridge which it’s important to empty your self!

Shut the bathroom flap securely
The primary is pretty self-explanatory: be sure to shut the flap between you and your holding tank after every use of the bathroom. You’ll actually remorse it in case you don’t!
That is usually the largest explanation for RV bogs smelling like a sewer- the methane gasoline leaks out of a hairline crack someplace and boy have you learnt it!
CLEAN REGULARLY to keep away from RV rest room odors
I hate to say it, as a result of NO-ONE enjoys cleansing a bathroom, however it actually does assist. Give your rest room a each day wipe down with antiseptic (or candy smelling cleaner).
I maintain mine in a helpful spritz bottle and use after a bathe to wash the world. I then wipe down the bathroom (in case you use disposable wipes, do NOT throw them into your rest room after use- put them in with the opposite garbage.)
The opposite factor which might scent in an RV rest room are the drains. An important product to make use of down the drains for the waste tank is Zoflora. Poor it neat down the bathe drain when you could have water in your tank and this can assist maintain the dreaded waste tank smells at bay. My pal’s favorite scent is the Linen Contemporary!
I’ve a walk-in rest room/ bathe unit, so the drain in my motorhome works onerous to do away with EVERYTHING. Attempt to keep away from placing ‘bits’ down your drains (each in bogs and kitchens) and clear the drains frequently.
A cup of baking soda combined with water helps maintain drains clear and scent free. Learn extra on learn how to clear your motorhome water tank.
Hair catcher
You probably have (or are!) ladies with LONG hair, you might want to filter the drain frequently. All that hair will get washed down the drain and collects different bits… which smells disgusting.
You probably have this bother, these are superb for catching hair!! Severely- so good. Simply ensure that they suit your camper drain.
USE ENOUGH LIQUID to do away with holding tank odours
That is counter-intuitive, I do know. ESPECIALLY in case your RV rest room makes use of your contemporary consuming water for flushing. However you NEED sufficient water in your rest room to cease smells- ‘dry’ camper bathrooms scent MUCH worse.
I may go into a protracted and technical description about methane gasoline launch from dried out waste yada yada… however frankly, no person must learn that, so simply belief me that wetter is healthier. Sure, you may snigger. I doubt many children are studying this! 😉
After all, don’t use TOO a lot water- you’ll replenish your RV waste tank a lot faster. It’s a fragile stability.
EMPTY the waste frequently
One of the best ways to cease camper waste smelling like a sewer is to… empty the sewer! The extra usually you empty, the much less it’s going to scent. This additionally comes again to eliminating the stuff letting off the gases. Now, I do know this is among the greatest cons of RV life, however it’s a small worth to pay for the liberty we love a lot!
If you happen to use a conveyable rest room cassette in your motorhome, all the time ensure that to scrub it out correctly EVERY TIME (utilizing the faucet supplied on the emptying station). I fill with water and empty a minimum of a few occasions to ensure every part is out.
If you happen to can’t empty your RV waste like that, this sewer tank rinser fixes onto your waste outlet and lets you actually get the tank clear.
BE CAREFUL WITH TOILET PAPER
I by no means ever put our rest room paper down the motorhome rest room. I take advantage of a bin within the rest room which is for this objective, and that bin will get emptied as usually as I can, normally as soon as a day.
I lived on boats for 15+ years and that is completely regular for me, however I do know that many individuals discover this ‘a bit bizarre’.
Nonetheless, in case you don’t put your paper down the bathroom you reduce the chance of blockages in your waste tank attributable to wadded, moist paper. Many individuals use far an excessive amount of paper- I’ve needed to study to lower the quantity I take advantage of.
One other benefit to not placing rest room paper within the cassette or black water tank is that the bathroom doesn’t get full so usually= extra time for wild tenting/ boondocking!
If that is too gross for you, use further water each time you utilize your camper toilet- it helps soften the paper. Additionally, use the most cost effective rest room paper you may find- NOT the ‘authorized RV or motorhome paper’. Severely, grocery store personal model stuff will dissolve very well!! However again- extra water and ‘stuff’ in the bathroom will trigger it to replenish quicker!

Intelligent tips to do away with RV rest room smells
It is a nice trick to maintain your RV rest room smelling good all day lengthy. Conceal bogs scents or sachets someplace out of the best way, and they’re going to launch a scrumptious scent all day lengthy.
Watch out when you have pets- ensure that any sachets are out of vary as many will not be appropriate for pets.
In case your RV rest room smells when flushed, strive placing a bit of scent or important oil within the water flush. (NOTE- do NOT do that in case your rest room makes use of your contemporary water!!!!) These charcoal pouches are nice for captures odours however keep in mind you might want to “refresh” them within the sunshine to “reactivate” them.
You probably have a bathroom cassette in your van, motorhome or camper then you may clear the cassette utilizing a particular cleaner.
Match a vent or SOG unit
Many RVs have already got vents inbuilt (usually it’s a crack in these pipes which causes your RV rest room to scent like a sewer (or rotten eggs; beautiful!)
Nonetheless, many campers and motorhomes don’t have any vent in any respect of their tiny bogs, so it may well actually assist to put in one.
A SOG unit is a vent which runs every time the bathroom flap is open. This helps launch the gases which construct up inside the bathroom holding tank, sending them out via the vent as an alternative and preserving your camper scent free.
I put in a SOG in my final motorhome and it was actually helpful. Listed below are a few ideas for becoming it:
- Be sure the vent for the SOG isn’t anyplace close to the door to your motorhome. In any other case, all these smells which have come out of the holding tank go straight again into your residing space…!!
- In case your rest room is close to the door, think about venting rest room odors up and out on the roof.
- Ensure you shut the flap SECURELY after utilizing the toilet- or the SOG retains working, and working.
