Self cleaning toilets work pretty well for this. Odor doesn't just sit in the air if the room is ventilated at all. Usually it's a result of micro-organisms on surfaces covered in biological material and water. Most toilet odors are a result of a film of feces remaining on the bowl and seat after flushing. This is why, if you clean a toilet after using it, the odor will dissipate in less than a minute.
Regular cleaning, de-humidification, filling drain traps with water, and self cleaning toilets is more than enough to keep a restroom odor free.
If the toilet is not the best place for those sounds, I don't know where. As long as the odor is managed, the sounds are inevitable. Maybe a loud air extractor?
Much of the smell in a toilet is your butt, not the bowl. If smell is an issue, wipe sooner or do an intermediate flush. (Or take the hint and change your diet.)
And air circulation, or lack thereof!
Yes, the one in my building has crappy air circulation (no pun intended!) and the facilities people know this, but they "won't" fix it (too expensive for FANG company to fix a toilet).
The solution: they put those fruit-smelly things in every corner of the toilet. Not only does this NOT solve the problem, The only thing, IMHO, this does is make you hate fruits :-(
I installed a composting toilet a few months ago at an off-grid cabin in the mountains. The important thing to get right is the venting system. This keeps a negative pressure in the compost chamber so air is continually drawn down through the toilet and up out the vent stack. When this is working correctly the bathroom will have no smell at all.
The second thing to worry about is the overflow drain. Depending on temperature and usage, urine may not evaporate faster then it is added. There is an overflow drain to handle this situation. Local building codes may require you to pipe the overflow to a conventional septic system, thus negating a lot of the cost and simplicity benefits of a composting toilet.
I prefer the engineering solution that improves the smell in restrooms.
A laminar (sp) flow "air-curtain" from fresh air directed down at the doorway to isolate the restroom. Combined with an overall positive (to local environment) pressure airflow design such that the restroom is one of the lowest-draw places in the building and has a direct egress for ejecting air.
The toilet could probably be improved by use of a UV clear lid shaped to let any backspray drip back inside of the toilet, a UV sanitation lamp (on either low voltage AC or DC with ground-fault protection systems), and maybe some minor automation to lift the lid and/or seat again depending on settings.
Upgrade to modern bidet (asian/Japanese style) toilet optional.
The last time I read about this technology there was a concern that there would be lasting smell from the toilet due to how it cleans itself (improperly). Has the issue been fixed?
I believe you also need to remove a poop-filled/stained component from it every few months, but this would probably be just a minor inconvenience for people who haven't even owned a modern toilet before.
Thanks for the toilet link... That looks really interesting. What do you think of it? Other than that website,I cannot find anything about that toilet anywhere. I'm confused about where the waste goes and how it can have no smell... Is it only for peeing?
When I was a kid, we had a carpeted bathroom toilet area.
What lunacy. Mold grows easily (carpet was always damp in high humidity summers, due to condensation, near the toilet), and worse, one bad flush and your carpet is now literally encrusted with human shit.
I don't understand what goal that will accomplish. You might wash the walls of the toilet slightly, but that's not where the bacteria are, they would be in the center, in the bulk of the material.
Plus toilets are designed to prevent you from doing that, they try very hard to be either fully closed, or fully open.
And, even if you succeeded, by releasing some water in advance, you reduce the pressure of the flush, which would elongate it, instead of rapidly removing the material, and time with water flowing = amount of aerosol.
The correct answer is: always put seat and lid down, as this prevents the bathroom from being filled with a fine mist of your urine/faeces when you flush.
Regular cleaning, de-humidification, filling drain traps with water, and self cleaning toilets is more than enough to keep a restroom odor free.
