If you’ve been thinking about upgrading your bathroom, the Toto Aurora is worth a serious look. This is one of the most talked-about toilet releases of 2026 — and for good reason. The Aurora isn’t just a good-looking fixture. It’s built around a completely new flushing technology called the INTEGRAVITY SYSTEM, and once you understand what that means, it changes how you think about what a toilet can actually do.
For Kirkland homeowners who want a cleaner, lower-maintenance bathroom without spending their weekends scrubbing, this toilet delivers. And when you pair the right product with a professional installation, you get something that works exactly the way it should — from day one.
Here’s what you need to know about the Toto Aurora, the INTEGRAVITY SYSTEM, and what a proper installation looks like.
What Makes the INTEGRAVITY SYSTEM Different
Most toilets flush the same basic way they always have. Water drops from the tank, moves through the bowl, and carries waste down the drain. It works, but it’s not particularly efficient at cleaning the bowl itself.
The INTEGRAVITY SYSTEM changes that completely.
It’s a dual-valve, nested-tank design that sequences the rim wash and siphon jet separately PR Newswire — rather than releasing everything at once like a standard gravity flush. That sequencing is the key. By timing those two actions precisely, the system extends bowl and rim cleaning coverage by up to five times compared to standard gravity flush systems. Morningstar
What that means practically: the water moves faster, covers more surface area, and does a more thorough job with every single flush.
The INTEGRAVITY SYSTEM works together with Toto’s TORNADO FLUSH to create a powerful centrifugal washing action that rinses the bowl more efficiently. CEFIONTECT — Toto’s nanotechnology ceramic glaze that prevents waste and debris from sticking to the bowl surface — and you’ve got a toilet that stays cleaner between cleanings without extra effort.
The whole system runs at either 1.28 or 1.0 gallons per flush. So you’re getting a dramatically more powerful clean while actually using less water than older toilets.
Here’s a quick breakdown of how the key technologies work together:
| Technology | What It Does |
|---|---|
| INTEGRAVITY SYSTEM | Dual-valve flush engine that sequences rim wash and siphon jet for extended coverage |
| TORNADO FLUSH | Creates centrifugal water action for 360-degree bowl cleaning |
| CEFIONTECT Glaze | Nanotechnology ceramic coating that prevents waste from sticking |
| PREMIST | Wets the bowl surface before each use to aid waste removal |
| EWATER+ | Mists the wand and bowl with electrolyzed water, reducing need for cleaning chemicals |
That’s a lot of technology working together in the background — quietly, efficiently, every time you flush.
The Aurora WASHLET+: Design and Features That Actually Matter
The INTEGRAVITY SYSTEM is the engine under the hood. But the Aurora’s WASHLET+ integration is what makes the day-to-day experience feel completely different from a standard toilet.
The Aurora is a one-piece toilet that’s designed to work with the WASHLET+ system. The WASHLET seat sits on top of the toilet, but what makes the Aurora different is how cleanly everything integrates — the design conceals the WASHLET+ power cord and water supply hose, so there are no visible cables or hoses running along the outside. The result is a much cleaner look than a standard toilet with a bidet seat added on as an afterthought.
The fully skirted design conceals the trapway, giving the toilet a sleek, understated look that’s also easier to clean. No exposed hardware, no hard-to-reach crevices collecting grime.
From a design standpoint it looks sharp in a modern Kirkland bathroom. But the features are where it really stands out.
WASHLET+ Features on the Aurora:
- Heated seat — no more cold seat on a winter morning
- Instantaneous water heating — warm water on demand, no waiting
- Five spray settings — fully adjustable for personal preference
- Wireless remote with 4-user memory — saves settings for up to four household members
- Automatic PREMIST — wets the bowl before each use so waste doesn’t stick
- EWATER+ system — mists the wand and toilet bowl with electrolyzed water, reducing the need for harsh cleaning chemicals
- Nightlight — a small detail that makes a real difference at 2am
- Universal Height design — supports comfort and accessibility across a wide range of users PR Newswire
The Aurora is also ADA compliant, which matters for households thinking about long-term accessibility.
One practical note for installation — the Aurora requires electricity. For installations where there isn’t an outlet nearby, a licensed electrician should install one. A dedicated 20-amp GFI circuit is recommended, and local codes should always be followed. This is something worth knowing before the toilet arrives at your door, not after.
What Toto Aurora Toilet Installation Looks Like in Kirkland
Installing the Aurora isn’t a standard toilet swap. There’s more to it than pulling out the old toilet and bolting in the new one — and getting it wrong can mean leaks, electrical problems, or a WASHLET that doesn’t perform the way it should.
Here’s what a proper installation actually involves:
Before the toilet arrives:
- Confirm your rough-in measurement. The Aurora comes ready for a 12″ rough-in but can be adapted for a 10″ or 14″ rough-in with a separately sold adapter. Getting this wrong means the toilet won’t fit correctly against the wall.
- Check your shut-off valve. Older Kirkland homes often have plastic gray shut-off valves that are unreliable. If yours is due for replacement, that gets handled before the new toilet goes in.
- Verify your electrical situation. A dedicated 20-amp GFI circuit is recommended. If you don’t have an outlet in the right location, an electrician needs to come in first.
During installation:
- Remove the existing toilet cleanly without damaging the floor or the flange
- Inspect the flange condition — a damaged flange needs to be repaired before anything goes on top of it
- Set the wax ring and install a Unitfit flange
- Set and secure the toilet
- Connect the water supply line
- Mount the WASHLET seat and connect it to the concealed supply hose and power cord
- Test all functions — flush, spray settings, heated seat, PREMIST, and EWATER+
What gets purchased separately: The Aurora does not include a wax ring or water supply lines — but don’t worry about tracking down parts. We supply everything you need, from the toilet and WASHLET to the wax ring and supply lines.
A lot of homeowners look at the Aurora and assume it installs like any other toilet. It doesn’t. Between the electrical requirement, the rough-in verification, and the WASHLET+ setup, this is a job that goes smoothly when someone who’s done it before is handling it.
