The Ultimate Buying Guide: Choosing Your One Piece Toilet Bowl
A one-piece toilet bowl offers a sleek, modern look compared to traditional two-piece toilets. They combine the tank and bowl into a single unit. This guide helps you pick the best one for your bathroom.
Key Features to Look For
When shopping for a one-piece toilet, several features make a big difference in how it works and how easy it is to clean.
Bowl Shape and Comfort Height
- Elongated vs. Round Bowl: Elongated bowls offer more comfort for adults. Round bowls save space, which is great for smaller bathrooms. Decide what fits your space best.
- Comfort Height: This means the seat sits higher, usually around 17 to 19 inches from the floor. Taller people and older adults often find comfort height much easier to use.
Flushing Power and Efficiency
- M-A-P Rating (Maximum Performance): Look for a high M-A-P score (usually 800 or higher). This shows the toilet effectively removes waste in one flush. Good flushing power prevents frustrating double-flushes.
- Gallons Per Flush (GPF): Modern toilets use 1.6 GPF or less. Water-efficient models (like 1.28 GPF) save money on your water bill over time. Check if your area requires a specific low-flow rating.
Cleaning and Design
- Skirted Trapway: This is a huge plus for cleaning! A skirted design means the sides of the toilet are smooth, hiding the usual curves and pipes (the trapway). You just wipe the smooth surface clean.
- Seat Included: Some models do not include the toilet seat. Always check the box contents so you do not have to buy a separate seat later.
Important Materials Used
Almost all good quality one-piece toilets use vitreous china. This material is very strong and resists stains well.
- Vitreous China: This is a type of ceramic coated with a porcelain enamel finish. It resists scratches and stains. Higher quality china feels heavier and denser.
- Internal Components: Check the flushing mechanism inside the tank. Brass or durable plastic components last longer than cheap, thin plastic parts.
Factors That Improve or Reduce Quality
The quality of a toilet affects how long it lasts and how often you need repairs.
What Improves Quality:
- Glazing Technique: Toilets with a very smooth, thick glaze resist waste sticking to the bowl surface. This makes flushing more effective.
- Brand Reputation: Established brands often use better internal parts and provide longer warranties.
What Reduces Quality:
- Thin Porcelain: A cheaply made toilet feels light. Thin porcelain can chip more easily over many years of use.
- Plastic Flush Valves: If the internal flush mechanism is made of very thin plastic, it might break or leak sooner than brass or heavy-duty plastic parts.
User Experience and Use Cases
One-piece toilets shine in specific bathroom settings.
- Modern Bathrooms: Their seamless look fits perfectly in contemporary or minimalist designs. They look very clean.
- Ease of Installation (Slightly Harder): Because the tank and bowl are one heavy unit, installation can sometimes be slightly trickier than assembling a two-piece toilet. You might need an extra set of hands for lifting.
- Cleaning Time: This is where they win. No gap between the tank and bowl means no dirt collects in that hard-to-reach seam. Cleaning becomes much faster.
Top 10 Frequently Asked Questions (FAQ) About One Piece Toilets
Q: Are one-piece toilets harder to install than two-piece toilets?
A: Yes, slightly. They are heavier because they come assembled, so moving them into place takes more effort.
Q: Do one-piece toilets cost more money?
A: Generally, yes. Because manufacturing them as one solid piece requires more complex molds, they usually have a higher initial price tag than basic two-piece models.
Q: How do I clean the exterior of a one-piece toilet?
A: Use a soft cloth and mild, non-abrasive cleaner. If you choose a skirted model, you simply wipe the smooth sides, which takes seconds.
Q: What is the main advantage of a skirted trapway?
A: The main advantage is easy cleaning. You avoid scrubbing around the curves and crevices where dust and grime collect on standard toilets.
Q: Will a one-piece toilet fit in my small bathroom?
A: It depends on the dimensions. Check the “rough-in” measurement (distance from the wall to the drain hole). Make sure the overall length of the one-piece unit fits comfortably.
Q: Are one-piece toilets less reliable for repairs?
A: No. While the parts inside are similar to two-piece toilets, they are still accessible by removing the tank lid. Repairs are usually straightforward.
Q: Should I choose an elongated or round bowl?
A: Choose elongated for maximum adult comfort, especially if you have a larger bathroom. Choose round if space saving is your top priority.
Q: What does “WaterSense certified” mean?
A: This label means the toilet meets strict EPA guidelines for water efficiency while still providing excellent flushing performance.
Q: How long should a quality one-piece toilet last?
A: A good vitreous china toilet with quality internal parts should last 15 to 25 years with normal care.
Q: Does the one-piece design affect flushing power?
A: No. Flushing power relies on the design of the trapway and the water delivery system (like the rim jets), not whether the tank and bowl are separate or combined.
