Picking a new toilet seems simple until you start comparing models. If you're looking at TOTO toilets, you've probably stumbled across two popular lines: the Aquia and the Nexus. Both are solid choices, but they have some real differences that matter.
I've spent time researching both models, and I'm going to break down everything you need to know. No fancy jargon, no sales pitch—just straight facts to help you decide which one fits your bathroom and budget.
Key Takeaways
- TOTO Aquia is a two-piece toilet with a modern design and excellent flushing performance
- TOTO Nexus is a one-piece toilet with a sleeker look and easier cleaning
- Aquia models are generally more affordable but take up slightly more space
- Nexus toilets cost more upfront but offer a seamless, contemporary appearance

- Your choice depends on budget, bathroom size, and cleaning preferences
What Makes TOTO Toilets Special?
Before we jump into the toto aquia vs nexus comparison, let's talk about why people love TOTO toilets in the first place.
TOTO is a Japanese company that's been making toilets since 1917. They're known for innovation, quality, and water efficiency. When you buy a TOTO, you're getting proven technology that works.
Both the Aquia and Nexus lines use TOTO's Tornado Flush System. This means they clean the bowl really well with less water. According to Big Write Hook, quality bathroom fixtures can actually increase your home's value, and TOTO definitely fits that category.
TOTO Aquia: The Budget-Friendly Performer
The TOTO Aquia is what we call a two-piece toilet. The tank and bowl are seperate pieces that get bolted together during installation.
Design and Look
The Aquia has a clean, traditional look that fits most bathrooms. It's not super fancy, but it's not boring either. The design is what I'd call "modern classic"—it won't look dated in five years.
The two-piece design means there's a visible seam where the tank meets the bowl. Some people don't mind this, others prefer the seamless look of a one-piece toilet.
Flushing Performance
Here's where the Aquia really shines. It uses TOTO's Dynamax Tornado Flush technology with a dual-flush option:
- 0.9 gallons per flush (light flush)
- 1.6 gallons per flush (full flush)
That's seriously efficient. You'll save water and money on your utility bills. The tornado flush creates a powerful swirl that cleans the entire bowl, so you won't be reaching for the brush as often.
Installation and Maintenance
Because it's a two-piece toilet, the Aquia is a bit easier for DIY installation. You can handle each piece separately, which makes it less awkward to maneuver.
Cleaning is pretty straightforward, though that seam between the tank and bowl can collect dust. The bowl has TOTO's CeFiONtect glaze, which is a super-smooth ceramic coating that prevents stuff from sticking.
TOTO Nexus: The Premium Choice
The TOTO Nexus takes things up a notch. It's a one-piece toilet, meaning the tank and bowl are molded together as a single unit.
Design and Aesthetic
The Nexus has a sleeker, more contemporary look. Without that visible seam, it looks more like a piece of modern art than a toilet. If you're going for that high-end spa bathroom vibe, the Nexus fits perfectly.
It sits a bit lower than the Aquia too, which some people find more comfortable. The overall profile is more compact and streamlined.
Flushing System
The Nexus uses the same dual-flush technology as the Aquia:
- 1.0 gallon (light flush)
- 1.28 gallons (full flush)
Notice that the full flush uses less water than the Aquia's full flush. That's pretty impressive. The flushing power is just as strong, thanks to TOTO's engineering.
Cleaning and Durability
This is where the Nexus really wins. That one-piece design means no seam to collect grime. You can wipe down the entire toilet in seconds. It also has the CeFiONtect glaze, so the bowl stays cleaner longer.
The one-piece construction is also more durable. There's no risk of the tank-to-bowl connection loosening over time.
TOTO Aquia vs Nexus: Side-by-Side Comparison
Let me break down the main differences in a simple table:
| Feature | TOTO Aquia | TOTO Nexus |
| Design | Two-piece, traditional | One-piece, modern |
| Height | Standard (varies by model) | Slightly lower profile |
| Flush Type | Dual-flush (0.9/1.6 GPF) | Dual-flush (1.0/1.28 GPF) |
| Water Efficiency | Excellent | Slightly better |
| Cleaning Ease | Good (seam present) | Excellent (seamless) |
| Installation | Easier (two pieces) | Harder (heavier, one piece) |
| Price Range | $400-$600 | $600-$900 |
| Best For | Budget-conscious buyers | Modern, high-end bathrooms |
Which One Uses Less Water?
Both toilets are WaterSense certified, meaning they meet EPA standards for water efficiency. But if we're splitting hairs, the toto aquia vs nexus water usage favors the Nexus slightly.
The Nexus uses 1.28 gallons max compared to the Aquia's 1.6 gallons. Over a year, that difference adds up. A family of four could save about 3,000 gallons per year with the Nexus.
That said, both toilets will dramatically reduce your water usage compared to older toilets that use 3.5 to 7 gallons per flush.
Installation: What to Expect
Installing the Aquia
The two-piece design makes the Aquia lighter and easier to handle. You'll install the bowl first, then mount the tank. Most handy homeowners can do this themselves in a couple hours.
You'll need:
- Basic plumbing tools
- A wax ring
- Supply line
- Tank-to-bowl bolts (usually included)
Installing the Nexus
The Nexus is heavier and more awkward because it's one piece. You might want a helper or a professional plumber. The installation steps are simpler in some ways (no tank-to-bowl connection), but the weight makes it trickier.
Professional installation typically costs $150-$300, which you should factor into your budget.
Price Breakdown
Let's talk money. This is often the deciding factor in the toto aquia vs nexus debate.
TOTO Aquia pricing:
- Entry models: $400-$500
- Mid-range models: $500-$600
- With upgraded features: $600-$750
TOTO Nexus pricing:
- Entry models: $600-$700
- Mid-range models: $700-$850
- Premium models: $850-$1,000+
You're looking at roughly $200-$300 more for the Nexus. Is that worth it? Depends on your priorities and budget.
Comfort and Height Options
Both toilet lines come in different height options. TOTO calls their taller models "Universal Height" or "Comfort Height."
These are about 17-19 inches from floor to seat, compared to standard toilets at 15 inches. The taller height is easier on your knees and back, especially for older adults or people with mobility issues.
Both the Aquia and Nexus are available in comfort height, so that's not a differentiator between them.
Maintenance Over Time
Aquia Maintenance
The Aquia is pretty low-maintenance. The main thing to watch is that seam between the tank and bowl. Wipe it down regularly to prevent buildup.
The CeFiONtect glaze means you won't need to scrub as hard or as often. Replacement parts are easy to find if something goes wrong.
Nexus Maintenance
The Nexus requires even less maintenance. That seamless design means there's nowhere for grime to hide. A quick wipe-down once a week keeps it looking new.
Because it's one piece, there's less that can go wrong mechanically. No tank-to-bowl connections to leak or loosen.
