TOTO Neorest LS vs NX1: What is the difference in 2026?
The TOTO Neorest LS and the Neorest NX1 are two of the most advanced smart toilets TOTO builds. They run the same core cleaning technology, so the real decision comes down to design, seat size, finish options, and price.
Quick answer: Choose the Neorest LS if you want custom trim finishes and clean architectural lines. Choose the Neorest NX1 if you want a sculptural, one of a kind shape and a larger, wider seat. Both clean exactly the same way.

Because the daily experience is so similar, the comparison comes down to the few differences below.
The real differences explained
Body shape and design
This is the most visible difference and the one that drives most purchase decisions.
The Neorest LS uses a rectangular, architectural form with sharp lines and a clearly defined tank section. The look is modern and intentionally angular. In a bathroom with stone slabs, linear faucets, and clean cabinetry, the LS feels native.
The Neorest NX1 uses an organic, egg shaped form. TOTO describes the silhouette as inspired by an earthen vase thrown on a pottery wheel. The body flows from bowl to rear with no visible breaks. It is more sculpture than appliance, and in person it has a presence that photos do not capture.
If you are designing a bathroom around a single statement object, the NX1 is that object. If the toilet should fit quietly into a larger architectural language, the LS does that better.
Seat size
The NX1 has a longer and wider seat than other Neorest models, including the LS. That means more seated surface area and added back support. For taller users or anyone who has found other smart toilets a little cramped, the NX1 is a genuine comfort upgrade.
The LS seat is standard for the Neorest line, which is already comfortable. But if seat room is a priority, the NX1 wins.
Finish and trim options
The LS is the only model in the Neorest range with customizable trim finishes. You choose Silver, Nickel, Black, or Matte Black to match the rest of your bathroom hardware. That matters in a renovation where you have already committed to a finish for your faucets, towel bars, and cabinet pulls.
The NX1 ships in Cotton White only, with a coordinated finish that suits its sculptural body. There are no trim choices.
If your bathroom is built around black hardware, the LS in Black or Matte Black is the only Neorest that follows your design language. If you have not committed to a coordinated metallic finish, the trim difference will not matter to you.
Hygiene technology: EWATER+ and ACTILIGHT
Both the LS and the NX1 use the same EWATER+ system on the wand, the bowl, and under the seat. From a hygiene standpoint, they are equivalent. The NX1 is not a cleaning upgrade over the LS.
ACTILIGHT, the UV plus zirconium glaze system, is reserved for the Neorest NX2. Neither the LS nor the NX1 includes it. If ACTILIGHT is something you want, see our TOTO Neorest Comparison Guide.
Price
The Neorest LS is priced from $8,007 for the Silver trim up to $10,409 for Matte Black, depending on the finish you choose. The NX1 is $11,452 in its single Cotton White finish, so it sits above every LS trim. Whether the gap is worth it depends on how much you value the sculptural form and the larger seat of the NX1.
Who should buy the TOTO Neorest LS
The LS is the right choice for most high end buyers. Choose it if:
- You want trim that matches your hardware. Silver, Nickel, Black, or Matte Black coordinates with your faucets, towel bars, and cabinet pulls.
- You prefer clean architectural lines over sculptural curves.
- You want the full Neorest hygiene suite without paying flagship prices.
- You are upgrading from the discontinued Neorest 700H. The LS is its natural successor.
Who should buy the TOTO Neorest NX1
The NX1 is for a more specific buyer. Choose it if:
- You want the toilet to be a statement piece. The NX1 is shaped to be looked at.
- You want more room. The longer, wider seat is noticeably more spacious day to day.
- You prefer organic, sculpted forms over straight lines.
- You want NX series prestige without stepping up to the NX2.
Installation requirements
The requirements are identical for both models:
- Power: a dedicated 120V, 15 amp GFCI outlet within 3 feet of the toilet
- Rough in: a standard 12 inch rough in. Neither model fits a 10 inch or 14 inch rough in.
- Water: a cold water supply line within reach. No hot water connection is needed, because both heat water on demand.
The most common pre install issue we see is electrical, so confirm the GFCI outlet and circuit before delivery. Professional installation is recommended but not required, and both units ship with full documentation.
Frequently asked questions
Does the NX1 clean better than the LS?
No. Both share the same EWATER+ coverage, TORNADO FLUSH, and CEFIONTECT glaze. The hygiene technology is identical. The NX1 is a design and comfort upgrade, not a cleaning one.
How much do the TOTO Neorest LS and NX1 cost?
The LS is priced from $8,007 (Silver) up to $10,409 (Matte Black) depending on trim. The NX1 is $11,452, so it sits above every LS finish. Promotions can change the price you pay, so check the live product pages for today's numbers.
Is the NX1 worth the price difference over the LS?
It depends on what you value. If you want the toilet as a statement piece, or the larger seat matters to you, the NX1 earns its price. If trim coordination matters more and the toilet is one of many fixtures, the LS gives you the same daily experience for less.
Does the LS come in colors other than Cotton White?
The LS porcelain body is Cotton White in every configuration. What you choose is the trim finish: Silver, Nickel, Black, or Matte Black.
What replaces the older Neorest 700H?
The Neorest LS replaces the 700H. If you are upgrading, the LS is the natural successor and adds under seat EWATER+ coverage, four user memory, and a seamless ceramic base.
Do the LS and NX1 work without power?
Both include a manual flush that works without power. The seat heater, dryer, bidet, and auto lid all need power. When power returns, the unit resumes normally.
The verdict
For most buyers in the high luxury Neorest segment, the LS is the right answer. It delivers the full Neorest hygiene story, four trim finishes, and architectural lines that suit a wide range of modern bathrooms.
For buyers who want the toilet itself to be sculptural, or who want a more generous seat, the NX1 earns its place above the LS. The cleaning systems are equivalent. The form and the seating comfort are not. There is no wrong choice here, only the one that fits your bathroom.
