My toliet broke at the flange and the bathroom floor was rotten. It took a whole month to get it fixed (between having the floor replaced, new sew pipe and toliet put in). So this composting toliet was a life saver. It was delivered fast, easy to set-up. Didn't smell inside the house, but did smell outside where I vented it, but buying a little extra pipe it can be vented up to the top of your house, or to a different location. If you do add more venting pipe just add a 3 inch ventilation fan to increase the air flow. I Had tried to use a bucket with toliet seat for a few days. But this composting is great for emergencies. I plan to keep it as a reserve
Toliet but keep using the normal toliet.

The transaction was smooth, and delivery was fast.
Just to let you know our toilet usage. We have a 750sf cabin that is primarily used on weekends and for a full week now and then. There have been long stretches of time when we do not go. Most of the time there are 3-4 people at the cabin and a few times we had 10 people.
We had a composting toilet at our cabin for 14 years. There were many problems with it. It was the type that had a heater, churn, and you had to add compost medium. I felt like I had to constantly monitor it. A few times guest did not fully understand how it worked and broke it. I got tired of repairing it and threw it away. Most of the Pros in the list are based on the problems I had with my old toilet.
I talked with people that had different composting toilets and researched different composting toilet models. The Separett Villa 9215 is the best choice for our needs.
Pros
"¢ Price of the 9215 is competitive.
"¢ No need for compost medium.
"¢ We can use it shortly after arriving at the cabin during freezing temperatures. No compost to thaw before using.
"¢ When we or guest leave the Separett gets emptied. No compost is left in the toilet when the cabin is vacant. Huge Plus!
"¢ Easy to use. Minimal user instructions. First time users can understand.
"¢ Few moving parts. If something breaks, I can easily remove the compost bucket and repair the toilet. All the parts can be accessed by opening the toilet.
"¢ Emptying the Separett is fast and easy.
"¢ Low power draw.
"¢ Quiet
"¢ Vent fan works well. No odors. I installed 30" of pipe with one sweep 90 for venting. We have a wood stove and a range hood fan that compete for makeup air.
"¢ The Separett takes up less room, looks good, and feels good to sit on.
Cons
"¢ The installation instructions state you can use SCH 40 PVC. I decided to use white SCH 40 PVC because the fittings that were provided did not fit snug and I needed a longer piece of straight pipe. The vent grid will not go inside SCH 40 PVC. The I.D. of SCH 40 is slightly smaller than the PVC that comes with the toilet. The O.D. is the same. I had to transition to a short piece of PVC that is provided so the vent grid could be installed. I believe the PVC that comes with the toilet is SCH 20.

Better than a flushing toilet! No smells in bathroom even immediately following a number 2! Great if you don't want to be grossed out brushing your teeth after someone's prior usage!

This isn't a thing people usually talk about but when it comes to compost toilet reviews, I've read just about everything.
We've had this toilet for about a year and a half now. So here's what I've learned.
So here goes.
1) Install is pretty easy as long as you've got the tools to cut a hole in the wall and you measure twice before cutting anything.
2) I know people say they use composting bags but with loose stools, those would begin to break down too quickly.
3) If you aren't sure if the fan really works, try accidentally unplugging it for a day. You'll be convinced after that!
4) Cleaning the bucket is pretty straight forward and simple. Definitely breathe through your mouth during the process. You'll thank me for that tip later.
5) There is a spot behind the bucket to the left that gets feces on it. I don't know how this happens. I just know it does. To combat this, I shove a paper plate in there and toss it in the bag when I change it.
6) If ANYTHING gets under the bucket somehow, cleaning that out is nearly impossible. There is tubing under there and the spinning tray the bucket sits on somehow (no idea how) stuff gets under there. I've yet to figure out how to clean that area.
7) The little divider thing gets urine stains under the front and if someone doesn't sit far enough back for a bowel movement (you have to sit ALL THE WAY BACK), then feces will get on the back of the divider. Or worse, it will miss the hole in the back entirely and you'll be putting on some gloves to clean a dirty job out of the urine space. Which will be very difficult because of the slots in the urine output.
7.1) If someone with dangles needs to pee, they may want to put on some gloves and remove the divider first. Otherwise their dangles will rest on the divider and that's uncomfy. Also, if you're getting on in years and you're dangles dangle more than they used to, the resting might happen even if you remove the divider. Sorry, I don't have a solution for that one.
8) Speaking of the urine output, it will get stained. We've tried the blue pucks Separett makes and they don't help. I've had to soak it in bleach and that is literally the only thing I've found that works. Which I don't like because we're trying really hard to not use chemicals.

9) This isn't our vacation toilet that we use occasionally, this is used daily by two adults and occasionally by visitors.
10) Visitors will need a toilet tutorial. And yes, EVERYONE must sit down to pee.
11) The difficult to attach rubber thing on the bottom of the toilet that's "optional" should not be optional. If you don't put that on there, you risk your toilet moving around. The last thing you want moving around is a toilet with a urine output tube at the back. I'm sure I don't need to go into further detail on that.
12) Caulking is your friend. I recommend a good clear bathroom and tub caulk to go around the entire base of the toilet.
13) The seat. We've found that after several months of daily use, the seat gets loose and needs to be tightened back down as it will sort of "clunk" and make you startle. So just good maintenance on the seat is recommended.
14) Some reviews will say they only clean it once a month. We clean ours weekly. If we wait a few extra days, we can definitely tell it's time to clean it by smell and by weight when I lift the bag out.
15) Paper. Some people put their paper in the toilet, some use a trash can for urine paper and some use s trash can for all paper. This is really up to you. We put ours in the toilet. We tried the trash can for urine paper and it smelled quite quickly. So we went back to putting it all in the toilet.

Would I buy again?
Yes, absolutely!
Does it need a few improvements?
Also, yes!

October 2022 Update: this toilet is holding up well with daiky use. Fan is still quiet, cleans easily and again no smell. It is holding up very well, even though made out of a lighter but very durable plastic. Still looks like new. I am still amazed but happy. We are not young, in our 70's and we can maintain this without issue.

We bought this toilet to use in what I call "Our Space" a renovated large open space that was a part of a barn, on kids property. We have been utilizing our 5th wheel bathroom. We wanted this space to be independent of the main house, convenient and not put any strain on the existing septic system.
Much research went into our decision to purchase the Villa 9215 and it did not disappoint.
This toilet was easy to install and works wonderfully. No odor! None. The fan is indeed quiet and very effective. Looks great as well.
I absolutely would recommend the Villa 9215 to anyone needing an alternative to conventional bathroom for any reason.
We use the heavy duty black bags as we are not further composting but disposing of the bag.
