Best Campervan Flush Toilets

Here’s my honest opinion about the plumbed RV toilet options for vanlife.

I’ve said it once and I’ll say it again… Having a toilet in my van was a no-brainer for the type of travel I was about to do:

  • Full Time
  • Off-Grid

I opted to install a plumbed RV toilet and a black water tank big enough to keep me going for about 2 weeks straight.

What’s a plumbed RV Toilet?

Unlike portable cassette or compost toilets, the plumbed RV toilet is essentially a toilet that has water supplied by the freshwater system and empties into a black water tank located under the van.

I used the RV Dometic flush toilet in my first van, and I loved it. They come in plastic and porcelain — I used the plastic one because it was lighter, and I thought the porcelain might crack and break over time.

With regular use, the plastic lasts about 3 years before it starts to look kind of gross as the plastic gets hard to clean inside the bowl. Thankfully, they aren’t that expensive and are generally always available. 

So why opt for a flush toilet in your van conversion?

If you’re looking to incorporate some of the “comforts of home” into your van, having a flush toilet is a good start.

Flush Toilets are an amazing fit for larger campervans, as they contain bigger holding tanks for toilet waste. Not to mention that because the holding tank is installed on the outside of the van, you’re less likely to experience odors like you might when using a cassette or compost toilet. 

Here are our recommended flush toilets for van conversions

Different Types of Campervan Flushing Toilets

Here’s a breakdown of the three main types of flushing toilets to help you decide which one you should choose for your campervan.

1. Gravity Flushing Toilets

A gravity flushing system disposes of your waste via an electric or manual pedal directly into a waste holding tank situated under the toilet. This means the waste is completely out of your sight! 

It’s a campervan toilet that most closely resembles a conventional or domestic toilet, hence providing a more comfortable experience than any other toilet.

2. Vacuum Flushing Toilet

This flushing toilet uses considerably less amount of water, making it a more eco-friendly choice. Here’s how it works: 

  • It pulls the waste from the toilet bowl as flush engagement activates the vacuum. 
  • The waste is then carried to a holding tank.

The vacuum flushing toilet is also versatile in terms of letting you change the position of the holding tank according to your RV.

3. Macerating Flushing Toilet

In a macerating flush, electric-powered blades turn your waste into a slurry, before it’s transferred to a holding tank. As soon as the flush is engaged, the waste is transported to a holding tank situated away from the toilet.

Disposing of the slurried waste is comparatively easier than in the other two flushing toilets.

The Need for a Black Water Tank 

If you choose to install a plumbed RV toilet in your van, then you will also need to install a black water tank to carry the waste.

With my van build, I decided to have 3 water tanks under the vehicle:

  1. Fresh Water (22 Gallons)
  2. Grey Water (25 Gallons)
  3. Black Water (10 Gallons)

The 10 Gallon black water tank allows me to go about 2 weeks before having to empty it.

A lot of people will determine that they don’t need a black water tank and will opt to use one of the various non-flush toilet options instead.


Toilet talk isn’t the most glamorous subject, but once you’re living on the road for extended periods of time, you’ll quickly realize how often this becomes a consideration every day.

That’s precisely why I chose to include a toilet in my van build (and always will!).

I hope this guide answers some of your questions about choosing a plumbed RV toilet for your van!
