Toilet Upgrade

On our very first trip out with the rig we discovered some issues.  One of the bigger problems for me was the little camper toilet.  I am not a tiny girl but come on… this thing barely had a seat!  For the 2 days we were out I felt like every time I had to do my business I was perched on a fine edge. Greg didn’t think it was bad, but I was defiantly grumpy, and the first thing I wanted to do was tear it out when we got home.


However we made a funny discovery.

When we went to dump the tanks, you need to drop in some black tank cleaner into the toilet to help keep things broken down.  When I went to raise the lid I realized the whole time we were out I was accidentally raising the seat too!  So I really was siting on a fine edge of about 1/2 inch of plastic.

As you can see in the pic I found online of our same toilet, there’s not much of a seat when you lift up the real thing!


After this we had a good laugh and agreed to wait till the shake down trip before deciding if we needed to invest in a new throne.  As you can see we decided it was worth the money.  It came down to 3 issues.

  1. The old toilet, a Thetford, was lower to the ground.  The newer one is standard height but still a few inches taller than the old one, and with my left knee completely shot it was slightly uncomfortable each time I used it.
  2. The shape of the bowl.  I realize this doesn’t mean much to some people but I’ve always found completely round bowls odd to sit on.  The toilet we ended up getting comes in both round and oval shape as well as bone and white colored.
  3. Cleanliness.  Even with filling the bowl prior to “dropping the kids off at the pool” it still seemed to just smear all over the sides of the bowl because it’s textured.  Who puts texture on the inside of a toilet bowl?!  This drove Greg nuts as he thought it was disgusting.


How we replaced the toilet

After a bit of research we ended up selecting the Dometic 320 series w/ hand spray.  It has a porcelain bowl with 2 bolt plastic base.  Essentially this toilet looks and feels like a residential toilet, even with the inside lip, standard size wooden seat, and holes that create a “swirl flush”, but without the tank in the back.  Oddly enough, Amazon with free shipping was actually less than camping world.  I know camping world is expensive but I never thought this would be eligible for Prime.

The price has since changed but we purchased it for $198.99 with Amazon LLC as the seller.

However, the first one arrived with the top lip shattered.  Normally they over-pack the fluff in breakable items, but this had nothing on the bottom and the toilet ships upside down with the porcelain at the bottom.


Luckily this is Amazon, so 2 min later we had reported the broken item, it was picked up the next day, and the following day the new one arrived with better packaging and whole.

2 very important items to take note of when replacing a Thetford Toilet for a Dometic.

  1. The are not the same size.  The base is the same with 2 bolts and it fits over the hole the same, but the top is longer in the front and back.  If you notice on our photos the original Thetford appears almost free standing, but the Dometic is snug against the wall.  It’s only about a 2-3 inch difference but if your toilet is already against the wall it may not fit, even the 310 (round bowl) seemed about the same length in back.  If you select the more oval then you also have a couple inches in the front as well.
  2. The Dometic comes with a new bottom seal but the hose doesn’t connect in the same place.  The original was a stiff 3/8th inch pex hose, which has no threads to screw into and we didn’t have a crimp tool to create one.  Because pex is so stiff and it wasn’t easy to reach the new connection — Our low cost solution was to purchase a flexible braided hose to hook up to the toilet just like you have at home and a sharkbite valve to connect the hose to the pex.  We cut the pex about 4 inches from the ground then used a sharkbite valve to bite into the pex and then connect it to the metal braid hose on the back of the toilet.  If you already have a crimp tool or your pex hose easily reaches the new connection this might not be necessary.


We lost the receipt but the total was no more than $15 for the supplies at Home Depot.

Special shout out to my Step-dad, Dean for putting this all together in about 15 minutes!

Our new throne!
