I'm studying/planning plumbing. I want an RV style for a black tank, not composting. Amazon reviews of toilets have me gunshy of picking one. Whatchyagot that you like, if you please?
 
I'm interested in this topic as well. I'm not quite to that point but I also plan to have a water flushing toilet. I plan to just buy a regular toilet from homedepot and add rubber seams and lid locks to tighten the seals, and modifying the vent tube so the upper tank can depressurize during a flush but not spill over After that it can work. Your you can always shut off the water too and do a flush to empty it before traveling. but you'll waste 2-3 gallons of water when you do that.
 
I have a dometic 320. Its a ceramic RV toilet with a seat. It feels just like my kohler crapper at home. Very comfy. It works well and is very efficient with water usage. I have mine installed in a dreamline showerbase as a wetbath configuration. Originally i didn't want a wet bath, but had no choice due to room. After having one, i really like it, less wasted space and i can use the shower wand to wash the toilet, not to mention, theres a seat in the shower for shaving etc.

I used a standard RV round toilet at my brothers fifth wheel last year and it was like hovering over a 5 gallon bucket. Dont recommend.

Those use a ton of water in flushing. Dont recommend a house toilet unless your bus is never going to move and has full hookups.
 
the dometic 300s are the easy standard that most have including me. however there are nicer toilets out there. there are ones that have many features like macerating built in. a macerating toilet lets you put the toilet anywhere and it pumps waste to the tank. where as a standard rv toilet needs to be over the tank and a straight drop. my favorite no expense spared macerating toilet is the thetford tecma. there are other features too... bidets, electric flush. it really depends on your needs.

my first toilet lasted about 10 years, it got replaced on a trip to camping world. i forget why it needed to go, but the dometcs are affordable.

i would avoid a house toilet - the water flow vs an rv style is dramatically different. standard toilets will use 3-4 gallons per flush and an rv toilet uses less that a quart. if you want to dump your waste tank every 3 days, use the household one. an rv toilet will get you a week or two per tank dump on a 50 gallon waste tank.

We also used the Dometic 320, having had a much smaller plastic toilet in our Class C the larger elongated Porcelain bowl of the 320 was much better, and the wife had insisted on Porcelain.

You probably already know this, for an RV toilet to function correctly it must be directly over the Black Tank, as a result when we were designing the interior layout of the Bus, We located where the Black tank would be and then where the Toilet would go.

As weird as it sounds we designed the interior of the Bus around the toilet.

We have been very happy with our choice, easy to clean and it has a lip around the inside edge that keeps any liquid in the bowl while driving.

I've gotta toilet in the mail, and I don't even have the roof raised yet. ;)

I'm waning my toilet just behind the rear tires, the tank will have to be almost where the mudflat is currently. Clearances are so close I'm getting the toilet now to make sure it's 8" rough in is correct.

I won't be using it that much to be a problem honestly so it would be fine for me. If I did ever live in it full time, I may look into the macerated one turf mentioned as My toilet certainly won't be directly over my tank.
 
re : MacErator

We had a MacErator in our '84 Peterbilt condo.
On its outlet, I fabricated a garden-spigot hose-bib so I could attach a garden-hose.
With the garden-hose, I could empty the six-gallon 'black' tank aways-away from the rig.
This reduced jiggling the entire rig to align with the dump-station.

Unsubstantiated rumors about me shoving the hose outlet down every gopher hole I could find are entirely false and never happened.

Nikitis - are you always solo? Others may have different needs and levels of comfort using the great outdoors. In the rain. At night at 3AM. Kids.

Flush toilets require accurately sloped drains (parking issues), and 3" drains at that. I'd be very hesitant to install something that the entire RV community has rejected.
 
By solo, you mean not going along with everyone else in the RV community. Not always, but if there's a feature I want, I will engineer a solution, or I may get down to it and decide not worth it. I don't have to reinvent the wheel all the time, but sometimes it's worth it to try. I'm not the average person and like to engineer solutions. However, that being said it could prove impossible potentially due to the bus design or where I place the toilet. There will be some spots it could work but I may not like those spots, so we'll see when I get down to it. But I'm definitely gonna shoot for it, and plan to let people know how it goes when I get to that point on my build thread where everyone can watch. I've already done a couple of mods others in the community wouldn't try and it's worked out quite well. (Switching audio air pressure beep for visual one as one example.) I plan to build a solar deck too which will switch between solar panels and a deck with slides.
 
By solo,I believe he was asking if you will be camping alone or if the family will be with you….

Oh sorry, I may have misread that comment, or you edited it. Either way, I'm the sole man in the family. I have a wife and 2 girls. The two girls don't know what a composting toilet is and would prefer a flushing toilet as that's all they know. The wife probably doesn't care which we use. She'd rather a flushing though if it's feasible. I'm more the one against composting and would rather a flushing toilet.

But we don't plan to live in it at all, just on like a week or two long vacations here and there, so the little we'd all use it it shouldn't be a problem. At the end of the week, dump it off at a dump station and toss in some cleaners into the tank for the intervals in-between vacations.
