Can You Put A Residential Toilet In An RV?

Technically, it is possible to install a residential toilet in an RV, but there are many things you need to consider. 

You need to ensure that the toilet can fit within the available space in your RV’s bathroom. 

Residential toilets need a standard plumbing system, so modifications are needed to connect it to your RV’s plumbing. 

The weight of the residential toilet should be within the RV’s weight capacity. 

What’s The Difference Between An RV Toilet And A House Toilet?

The main difference between an RV toilet and a house toilet lies in its design and functionality. RV toilets are specifically designed for mobile use and have unique features to handle limited water supply, space constraints, and waste disposal in recreational vehicles. They are lightweight, compact, and often use a water-saving flush system. 

In contrast, house toilets are designed for permanent installations, connected to a continuous water supply and a sewage system. They offer maximum comfort and convenience over portability and water efficiency.

How Does An RV Toilet Work?

An RV toilet operates using a simple yet efficient mechanism. It consists of a foot pedal or hand lever that activates a flush valve. When the pedal or lever is pressed, it opens the flush valve, allowing water from the RV’s water supply to rush into the toilet bowl. 

This water creates a swirling action, which helps to remove waste and clean the bowl. After flushing, the waste is directed to a holding tank located beneath the RV, where it is stored until it can be properly disposed of at a designated dump station.

How Does A Residential Toilet Work?

A residential toilet operates through a gravity-based flushing system. When the flush lever is pressed, a flapper valve in the toilet tank opens, allowing water from the household’s water supply to rush into the toilet bowl. The sudden influx of water creates a siphonic action, which efficiently removes waste and cleans the bowl. 

The force of gravity then carries the waste through the plumbing system, ultimately connecting to the municipal sewage system or a septic tank for proper disposal and treatment.

Will A Regular Toilet Seat Fit An RV Toilet?

A regular toilet seat will not fit an RV toilet due to differences in size and design. RV toilets are smaller and have unique shapes to accommodate the limited space within an RV bathroom. 

They need specialized toilet seats that are specifically designed to fit their dimensions and attachment points. It’s important to choose a toilet seat that is compatible with your RV toilet model to ensure a proper fit and functionality.

Can You Put An RV Toilet In A House?

Technically, it is possible to install an RV toilet in a house, but it is not recommended due to the following reasons. 

RV toilets are designed for specific RV plumbing systems, which differ from standard residential plumbing. The RV toilet may not fit the standard rough-in dimensions, and connecting it to the house plumbing system could cause issues with proper waste disposal and water supply. 

How To Install A Regular Toilet In An RV?

Installing a regular toilet in an RV is a complex process, but with the right plumbing expertise, you can install it. If you have know-how about the toilet installation, you can install it. However, if you don’t have any, we recommend calling a professional plumber. Here’s a step-by-step guide to installing a regular toilet in an RV.

  • Measure the available space in your RV’s bathroom to ensure the regular toilet will fit properly.
  • The first thing is to remove the existing RV toilet. Disconnect the water supply line and remove the bolts securing the toilet to the floor. Carefully lift and remove the RV toilet.
  • Since RV plumbing systems have different pipe sizes than residential systems, use a flange adapter to connect the RV pipe to the regular toilet’s flange.
  • Install a water line adapter to connect the RV’s water supply to the regular toilet’s fill valve.
  • Place the regular toilet over the flange adapter and align it with the mounting holes on the floor. Use bolts and washers to secure the toilet in place.
  • Attach the water supply line to the fill valve on the regular toilet.
  • Turn on the water supply and check for any leaks around the connections. Tighten if necessary.
  • Expert Tip 

RVs need additional ventilation for the regular toilet. Consult an RV plumbing expert to determine if you need to install a ventilation system.
