Connecting two toilets back to back can be a practical solution for small bathrooms or to create a disabled-accessible toilet. This process involves plumbing and may require professional help, especially if you're not comfortable with DIY projects. Here's a step-by-step guide to help you understand the process.
Understanding the Process
Before you start, it's crucial to understand that connecting two toilets back to back requires careful planning and the right tools. You'll need to consider the layout, plumbing, and waste disposal. This guide assumes that both toilets are of the same type (e.g., both are floor-mounted) and that you're connecting them in a straight line.
Tools and Materials Needed
- Tape measure
- Pencil
- Saw (hacksaw or reciprocating saw)
- Adjustable wrench
- Plumber's putty
- Teflon tape
- New wax rings (2)
- New toilet bolts (4)
- New toilet seat (if needed)
- New water supply line (if needed)
- New drain and vent pipes (if needed)
Planning the Layout
First, measure the space where the toilets will be installed. Ensure there's enough room for both toilets and that they can be positioned back to back. You'll also need to consider the location of the existing drain and water supply lines.

Wall-Frame Installation
If you're installing the toilets in a wall frame, you'll need to cut out a space for each toilet. Use a saw to cut the appropriate size hole in the wall frame. Ensure the holes are level and aligned with each other.
Removing the Existing Toilet
Before you can install the new toilets, you'll need to remove the existing one. Start by turning off the water supply and flushing the toilet to empty the tank. Disconnect the water supply line and the drain pipe. Remove the toilet bolts and lift the toilet off the flange.
Installing the First Toilet
Install the first toilet following the manufacturer's instructions. Ensure the toilet is level and properly sealed to the flange using a new wax ring. Connect the water supply line and the drain pipe. Test the toilet for leaks.
Installing the Second Toilet
Install the second toilet in the same manner as the first. However, you'll need to extend the drain pipe to connect to the first toilet's drain pipe. You may also need to extend the water supply line if it's not long enough. Ensure both toilets are securely fastened to the floor and that the drain pipes are properly vented.
Testing the Toilets
Once both toilets are installed, test them by flushing each one. Check for any leaks around the base of the toilets or at the connections. If there are no leaks, your back-to-back toilets are now ready for use.
When to Call a Professional
While this guide provides a general overview of the process, it's important to note that connecting two toilets back to back can be complex and may require professional help. If you're unsure about any part of the process, it's always best to consult with a licensed plumber.
