Hi All....My wife has never liked the toilet in the trailer. It's the same as any other trailer toilet made. After 15 years of listening to the complaints, I took it out and installed a low water consumption house toilet. Seems to work good, but some say there will be problems. I realize that it probably uses more water than the orginial, but 99.9% of the time we have full hook up where we stay. I also realize we will have to flush it before traveling to keep water from sloshing out. Is there any other reason I should not have used a house toilet? Thanks in advance.

1. I visualize it cracking when you go over that first big bump.2. we are always trying to go light, and that just adds more weight. I hope all goes well, but I am thinking of problemsjack L

Please, give us an update after a few thousand miles of towing. Let us know if there are any problems. I also think it would crack or leak from the bouncing, especially where the tank attaches to the bowl. Hopefully you will not have any problems. Your wife is happy. Nuff said.

Have you seen home toilets that use a pressurized water tank to flush the toilet? I put one in my house back in 95, and it never needed to be flushed twice! It used only about 1.2 gallons per flush, and according to the brochure from the manufacture, it put out 13 GPM for about 1.5 seconds, to clear the bowle and can dispose of 13 ping pong balls in one flush. So that type of tank would not need to be flushed before driving. Still the top might slide off the tank. A small velcrow strap should keep it in place.The problem? Well you guessed it - the 1.2 gallons of water with each flush. So you can fill a 30 gallon tank in about 20 flushes. That should provide enough capacity for a really long weekend, with two campers. Not so long with a family of 5. So no problem in your situation, with full hookups, and no long dry camping weekends.The weight of the toilet, held upright while going around curves might become a problem. You will find out if the hold down bolts try to break free, or damage the ceramics that hold them down. Good luck!Fred.

since I rarely flush ping pong balls, that stat does not affect my decision. ;)bumpy

Before we even used our TT for the first time i ordred and installed a Ceramic Thetford toilet with the hand spray option.
That original 5 gallon bucket that comes standard is no go.

I still don't see how you will keep the trap seal when traveling with a house toilet.

The ceramic RV toilets are just as "comfortable" as a house toilet and you can use as much water as you like in them to aid with flushing.

Probably the cost. Those upscale RV johns are pricier than a mid price point Kohler or American Standard residential model.

My Jayco came with a porcelin crapper which was a selling point for me, along with the 90 gal FW tank.

I would have suggested a one piece. You can probably count the flushes until full. Do you let DW pull the handle now that it must be done every day? Not sure if the 1.6gal would be enough to prevent a piramid with valve left open.

Bob.. I didn't change it just because of my wife. At least not completely. After a few years the seal started leaking and wouldn't hold water in the bowl. There for we got a small amount of odor in side. I was going to replace the seal and after taking it apart, the cables, springs, everything inside was rusted and was junk. After checking, I would put about the same $$ on this toilet as if I bought another trailor toilet. You know the saying "happy wife, happy life"

Not sure, but I believe some high end RV manufacturers offer residential commodes as an option. Curious to see how it works for you, as even the most basic residential toilet is cheaper than an RV toilet.........to buy or maintain/repair. Water consumption? Unless you're off the grid, I don't see a water problem as the toilets sold for residential use today only use something like 1.6 gal. a flush.

Keep the black tank valve closed like always; open when dumping UNLESS you get rid of the black tank altogether eg. when at a permanent site.

at one time I remember one of the RV toilet folks had several "improved" jobbies, much taller, closer to a residential. I think I would try one of those first.

Another problem to consider is the use of a wax ring to seal between the toilet and the drain pipe, the wax ring will loose it's seal with road travel and movement. There are some better quality RV Toilets on the market, you might have her "road test" those before taking the plunge (pun intended). JH

One more minor issue you may have is if the water sloshes out of the trap, or evaporates over time your TT will stink
