How to Install a Toilet in an RV

Installing a toilet in an RV is a relatively simple task, but it does require some basic tools and knowledge. In this guide, we will walk you through the process of choosing the right toilet, preparing your RV for installation, and installing the toilet itself.

Choosing the Right Toilet

The first step is to choose the right toilet for your RV. There are a few things to consider when making your selection, including:

  • Size and dimensions: The size of your toilet will be determined by the amount of space you have available in your RV. You will need to make sure that the toilet is not too large for the space, and that there is enough clearance for the door to open.
  • Flush type: There are two main types of toilets: gravity flush and pressure flush. Gravity flush toilets use the force of gravity to flush the waste away, while pressure flush toilets use a pressurized air tank to create a powerful flush. Pressure flush toilets are generally more efficient than gravity flush toilets, but they can also be more expensive.
  • Water usage: The amount of water used by a toilet is measured in gallons per flush (GPF). The average toilet uses about 1.6 GPF, but there are also toilets that use as little as 0.8 GPF. The amount of water your toilet uses will affect your overall water usage, so it is important to choose a toilet that is efficient.
  • Budget: The cost of a toilet can vary significantly, depending on the features and materials used. You will need to decide how much you are willing to spend on a toilet before you start shopping.

Preparing the RV for Installation

Before you can install a toilet in your RV, you will need to prepare the space. This includes removing the old toilet, installing a new toilet flange, and plumbing the toilet.

Removing the old toilet

To remove the old toilet, you will need to:

1. Turn off the water supply to the toilet.
2. Flush the toilet to drain the water from the tank.
3. Remove the bolts that hold the toilet to the floor.
4. Lift the toilet off the floor and set it aside.

Installing a new toilet flange

A toilet flange is a metal ring that is installed on the floor of the RV to support the toilet. To install a new toilet flange, you will need to:

1. Measure the diameter of the toilet drain opening.
2. Purchase a toilet flange that is the same diameter as the drain opening.
3. Mark the location of the toilet flange on the floor of the RV.
4. Drill a hole in the floor of the RV for the toilet flange.
5. Apply a bead of plumber’s putty around the outside of the toilet flange.
6. Insert the toilet flange into the hole in the floor of the RV.
7. Secure the toilet flange to the floor of the RV with screws.

Plumbing the toilet

To plumb the toilet, you will need to:

1. Connect the water supply line to the toilet.
2. Connect the drain line to the toilet.
3. Turn on the water supply to the toilet.
4. Flush the toilet to test the plumbing.

Installing the Toilet

Once you have prepared the RV for installation and plumbed the toilet, you can install the toilet itself. To install the toilet, you will need to:

1. Place the toilet on the toilet flange.
2. Align the holes in the toilet with the bolts in the flange.
3. Insert the bolts through the holes in the toilet and tighten them with a wrench.
4. Connect the water supply line to the toilet.
5. Connect the drain line to the toilet.
6. Turn on the water supply to the toilet.
7. Flush the toilet to test the installation.

Installing a toilet in an RV is a relatively simple task, but it does require some basic tools and knowledge. By following the steps in this guide, you can easily install a new toilet in your RV.

3. Installing the Toilet Seat

Once you have installed the toilet, you can attach the toilet seat.

Choosing the right seat

There are a few things to consider when choosing a toilet seat.

  • Size: The toilet seat should be the same size as the toilet bowl.
  • Style: There are a variety of styles of toilet seats available, including round, elongated, and split.
  • Material: Toilet seats are typically made from plastic, wood, or metal.
  • Comfort: The toilet seat should be comfortable to sit on.

Installing the seat

To install the toilet seat, you will need the following tools:

  • A screwdriver
  • A wrench
  • A toilet seat
  • Toilet bolts
  • Toilet washers
  • Toilet nuts

1. Remove the old seat. If there is an old toilet seat installed, remove it by unscrewing the bolts that hold it in place.
2. Clean the toilet bowl. Wipe down the toilet bowl with a cleaning solution to remove any dirt or debris.
3. Position the new seat. Place the new toilet seat on top of the toilet bowl. Make sure that the holes in the seat align with the bolts in the bowl.
4. Attach the seat. Secure the seat to the bowl by screwing in the bolts. Tighten the bolts until they are snug, but not too tight.
5. Install the washers and nuts. Place a washer on each bolt, followed by a nut. Tighten the nuts until they are snug.

Testing the seat

Once the seat is installed, test it to make sure it is secure. Sit on the seat and rock back and forth. The seat should not move or wobble.

4. Testing the Toilet

Once you have installed the toilet and toilet seat, you should test the toilet to make sure it is working properly.

Checking for leaks

The first thing you should do is check for leaks. Turn on the water supply to the toilet and flush the toilet. Look under the toilet for any leaks. If you see any leaks, you will need to tighten the connections or replace the seals.

Flushing the toilet

Once you have checked for leaks, flush the toilet again. The toilet should flush smoothly and completely. If the toilet does not flush properly, you may need to adjust the water level or replace the flapper.

Adjusting the water level

The water level in the toilet tank should be about 1 inch below the top of the overflow tube. To adjust the water level, turn the water supply valve to the toilet clockwise to increase the water level or counterclockwise to decrease the water level.

Installing a toilet in an RV is a relatively simple task. By following these steps, you can install a new toilet in your RV in no time.
