Choosing the Right Rear Outlet Toilet: Your Comprehensive Guide
A rear outlet toilet, also known as a back outlet or rear discharge toilet, offers a clever solution for specific plumbing situations. Instead of the typical waste pipe exiting from the floor, this type of toilet releases waste through a pipe directly out of the back. This guide will help you understand everything you need to know to make an informed purchase.
What is a Rear Outlet Toilet?
Imagine a toilet designed to connect to plumbing in a wall instead of the floor. That’s a rear outlet toilet! This design makes them ideal for basements, older homes with tricky floor layouts, or when you want a clean, modern look with no visible pipes on the floor.
Key Features to Look For
1. Flush Mechanism
- Single Flush: Uses one amount of water for every flush. It’s simpler and often more affordable.
- Dual Flush: Offers two flush options: a full flush for solid waste and a partial flush for liquid waste. This saves water.
2. Bowl Shape
- Elongated Bowl: Offers more seating space and is generally considered more comfortable.
- Round Bowl: Takes up less space, making it a good choice for smaller bathrooms.
3. Trapway Design
The trapway is the S-shaped pipe inside the toilet that holds water and prevents sewer gases from entering your bathroom. For rear outlet toilets, ensure the trapway is compatible with your wall plumbing setup. Some toilets have a concealed trapway for a sleeker look.
4. Water Efficiency (Gallons Per Flush – GPF)
Look for toilets with a low GPF rating. The US Environmental Protection Agency (EPA) WaterSense label means a toilet uses at least 20% less water than the federal standard. This saves money and helps the environment.
5. Height
- Standard Height: The typical toilet height.
- Comfort Height (or Right Height): Taller than standard toilets. These are easier to sit on and stand up from, especially for taller people or those with mobility issues.
Important Materials
Most rear outlet toilets are made from vitreous china or porcelain. These materials are:
- Durable: They resist chips and scratches.
- Non-porous: This makes them easy to clean and less likely to stain or hold odors.
- Heavy: This means they are stable and less likely to move.
Factors That Improve or Reduce Quality
Quality Enhancers:
- Smooth Glaze: A smooth, glossy finish on the bowl and tank makes cleaning easier and prevents waste from sticking.
- Strong Flush Valve: A good flush valve ensures a powerful and complete flush every time.
- Quiet Close Seat: Many toilets now come with seats that close slowly and quietly, preventing slamming.
- WaterSense Certification: As mentioned, this indicates excellent water efficiency.
Quality Reducers:
- Rough Glaze: A rough surface inside the bowl can be harder to clean and may lead to staining.
- Weak Flush: Toilets that don’t flush completely require multiple flushes, wasting water and time.
- Plastic Components: While some internal parts are plastic, overuse of plastic in the tank or flush mechanism can reduce durability.
User Experience and Use Cases
Rear outlet toilets are fantastic for specific situations. They are often chosen for:
- Remodeling Projects: When rerouting plumbing is difficult or expensive, a rear outlet toilet can be a simpler solution.
- Small Bathrooms: They can help create a cleaner, more open feel by moving the plumbing out of sight.
- Modern Aesthetics: The hidden pipework contributes to a minimalist and contemporary bathroom design.
- Basement Bathrooms: They are particularly useful when the main sewer line is in the wall rather than under the floor.
The user experience is generally the same as a standard toilet – you sit, flush, and it does its job. The main difference is in the installation and the visual appeal of a cleaner floor space. Ensure you have the correct wall rough-in measurement for a successful installation.
Frequently Asked Questions about Rear Outlet Toilets
Q: What is the main difference between a rear outlet and a standard toilet?
A: The main difference is where the waste pipe connects. Standard toilets connect to the floor, while rear outlet toilets connect to the wall.
Q: Are rear outlet toilets harder to install?
A: Installation can be simpler if your plumbing is already set up in the wall. However, you need to ensure the toilet’s outlet matches your wall’s rough-in measurement.
Q: Can I use a rear outlet toilet in any bathroom?
A: You can use them if your wall plumbing can accommodate the outlet. They are not a direct replacement for a floor outlet if your plumbing isn’t set up for it.
Q: What is a “rough-in” measurement for a toilet?
A: The rough-in measurement is the distance from the finished wall to the center of the drainpipe. For rear outlet toilets, this measurement is crucial for proper fit.
Q: How do I know if my bathroom is set up for a rear outlet toilet?
A: You will need to have a drain pipe exiting from the wall at the correct height and distance. It’s best to consult a plumber to check your existing setup.
Q: Do rear outlet toilets come in different styles?
A: Yes, they come in various styles, including elongated and round bowls, and different tank designs, just like standard toilets.
Q: Are rear outlet toilets more expensive?
A: Their price can vary, but they are often comparable to standard toilets. The cost might increase if significant plumbing modifications are needed.
Q: How do I clean a rear outlet toilet?
A: Cleaning is the same as a standard toilet. You use toilet bowl cleaner and a brush for the inside of the bowl and standard bathroom cleaners for the exterior.
Q: What is the advantage of a dual-flush rear outlet toilet?
A: A dual-flush toilet allows you to choose a lighter flush for liquids and a full flush for solids, which saves water and lowers your water bill.
Q: Where can I buy a rear outlet toilet?
A: You can find rear outlet toilets at most home improvement stores, plumbing supply stores, and online retailers.
