Fact checked by Ronal Dowens

How to Remove a Thetford RV Toilet

When living in an RV, one of its most essential components is its permanent toilet. For RVs that cost around $100,00, the common standard permanent toilet installed is Thetford toilets. However, sometimes, permanent toilets may need to be removed to be cleaned or to be entirely replaced. If that happens, as an RV owner, you must know how to remove a Thetford RV Toilet on your own.

There are plenty of Thetford RV toilet models, but their removal process is generally the same. Removing it is pretty simple, and you can do it in just under 15 minutes if you follow the steps stated down below.

What to Prepare


Before jumping to the step-by-step instructions, you must first prepare the following tools:

  • Flathead screwdriver
  • 1/2 -inch socket wrench
  • 12-inch socket wrench extensions
  • Rag

The tools mentioned above are commonly found in standard toolboxes. Also, if you are an RV owner, it is good to invest in these as it may come handy in other situations as well.

Step-by-Step Process


If you have all your tools ready, you are now prepared to remove your Thetford toilet. Here are the steps to do that:

Step 1: Turn Off the Water Supply

You wouldn’t want to make a mess by having water splash all over you when you are working. This is why, before doing anything, make sure that your water supply is turned off. Usually, RVs have a water pump switch nearby that you can just switch to “off.” If your RV is connected in an external water source, make sure to disconnect that as well temporarily.

Step 2: Remove the Bolt Cover

RV toilet bolt covers are what make them look seamless. It also keeps the actual bolts from being accidentally unscrewed for whatever reason and from corroding. So, when removing your Thetford toilet, you must remove it.

To do this, you will need to use a flathead screwdriver. Just put the tip of the screwdriver to the seams of the bolt cover and lift up. There are usually two of these, so you just have to do the same step to the other bolt covers.

Step 3: Remove the Actual Bolts


Once the toilet bolts are exposed, take your half-inch socket wrench and unscrew it. However, it is only straightforward if the bolts are located on the sides of the toilet. For some Thetford toilet models, reaching the bolts can be difficult, especially the ones that have bolts located in front and at the back of the toilet.

If you have a front and back bolted Thetford toilet, the best way to access the front bolt is by simply pressing down and holding the foot flush lever. On the other hand, to gain better access to the rear bolt, you can lift the seat cover. Then, take away the access hole that is the upper part of the hopper. Once you do this, you can now easily reach the back bolt. After that, use your 12-inch socket wrench extension and unscrew the rear nut.

Step 4: Lift the Toilet

When the bolts are unscrewed, the toilet can now be easily lifted up from its fixed position. When removing it, make sure to have a rag ready and place it immediately in the hole left by the toilet. Doing this will prevent bad odors from the plumbing to come inside the RV. It will also prevent contamination of the black water tank contents.
