The Smart Choice: Your Guide to Rear Outlet Toilets
Why a Rear Outlet Toilet?
A rear outlet toilet, also known as a back outlet or rear discharge toilet, is a smart plumbing solution. It’s perfect for bathrooms where traditional toilets won’t fit easily. This type of toilet connects to the drain pipe through the wall behind it, not the floor. This design saves space and offers more layout flexibility. If you’re renovating an older home or building a new bathroom in a tight spot, a rear outlet toilet can be a real game-changer.
Key Features to Look For
1. Flush System:
- Gravity Flush: This is the most common type. Water fills the tank and then rushes down into the bowl when you flush. It’s simple and reliable.
- Pressure-Assisted Flush: These use air pressure to create a stronger flush. They are good for clearing clogs but can be noisier.
- Dual Flush: Some models offer two flush options – a low-flow for liquids and a full flush for solids. This saves water.
2. Bowl Shape:
- Round Bowl: Takes up less space and is good for smaller bathrooms.
- Elongated Bowl: Offers more comfort for sitting.
3. Height:
- Standard Height: Around 14-15 inches from the floor to the top of the seat.
- Comfort Height (ADA Compliant): Around 17-19 inches. This is easier for people to sit down on and stand up from.
4. Trapway Design:
The trapway is the curved pipe inside the toilet that holds water to prevent sewer gases from entering your bathroom. For rear outlet toilets, ensure the trapway is designed for wall connection. Most come with a built-in or adjustable flange for this purpose.
Important Materials
Ceramic or Vitreous China:
This is the most common material for toilet bowls and tanks. It’s durable, non-porous, and easy to clean. High-quality ceramic resists stains and scratches.
Plastic (for tanks or internal parts):
Some tanks or internal components might be made of durable plastic. Ensure it’s good quality and built to last.
Factors That Improve or Reduce Quality
What Makes a Toilet Great:
- Water Spot: A larger water spot in the bowl helps keep it cleaner.
- Flush Power: Look for toilets with good reviews on their flushing performance.
- Quiet Operation: Some toilets are designed to flush quietly, which is a nice bonus.
- Easy Cleaning: Features like skirted traps (where the base is smooth and hides the pipes) make cleaning much easier.
What to Watch Out For:
- Weak Flush: Some cheaper models may not flush effectively.
- Leaking Parts: Poorly made seals or connections can lead to leaks.
- Difficult Installation: While many are designed for easy installation, some might require more complex plumbing.
User Experience and Use Cases
Who Benefits Most?
- Small Bathrooms: Rear outlet toilets are ideal for powder rooms or tight en-suites where floor space is limited.
- Basement Bathrooms: They can be a great option when you want to add a bathroom in a basement where the drain is located in the wall.
- Accessibility: Comfort height models are excellent for seniors or people with mobility issues.
Everyday Use:
Once installed, a rear outlet toilet functions much like a standard toilet. You’ll appreciate the extra floor space and the clean look. The main difference is the installation process, which often involves connecting to a waste pipe in the wall.
