What Sets the Nexus Apart From TOTO's Other Skirted Lines
The Nexus is the skirted TOTO line that comes only one way: elongated bowl, Universal Height, and a 12-inch or 14-inch rough-in with no 10-inch version in any configuration. That last point decides whether the Nexus is even an option in your bathroom, and it is the first thing to check.
Every Nexus bowl uses TORNADO FLUSH, which TOTO describes as a dual-nozzle water propulsion system with "two powerful nozzles that create a centrifugal, cyclonic rinsing action which reduces waste buildup and keeps the bowl cleaner." The rim is hole-free, so there is no ring of jets to scrub around. The ceramic is finished with CEFIONTECT, a glaze TOTO calls "extraordinarily smooth," with an ion barrier that keeps particulates from sticking to the surface.
Completely skirted, and what that means day to day
TOTO's spec sheets call the Nexus a "completely skirted design for a sleek and understated look that's easier to clean." There is no exposed trapway curving down the side of the bowl, which removes the hardest part of a toilet to wipe. If the skirt is not what you are after, the unskirted TOTO Drake is the obvious cross-shop, and it offers a 10-inch version on some models that the Nexus does not.
Universal Height and an elongated bowl on every model
Every Nexus toilet is listed at Universal Height with an elongated front bowl and seat. Universal Height puts the seat roughly 17 to 19 inches from the floor rather than about 15, which meets the ADA seat-height requirement and is what most people mean by comfort height or chair height. Our Universal Height versus standard height guide covers who benefits. There is no standard-height Nexus and no round-bowl Nexus.
Built to take a WASHLET+
The spec sheets state the Nexus is "specially designed to accommodate a WASHLET+," and that is structural, not marketing. The skirt conceals the bidet seat's power cord and water supply hose, so a WASHLET+ installs with nothing visible behind the bowl. You can buy the Nexus bare and add a seat later, or buy it as a matched WASHLET+ set with the S2, S5, S7 or S7A already fitted.
Is the TOTO Nexus a Good Toilet?
The TOTO Nexus is a good toilet for anyone who wants a skirted, easy-to-clean bowl at chair height with a high-efficiency flush, and it is a particularly good buy if a bidet seat is part of the plan. The flush is TOTO's current TORNADO FLUSH rather than an older system, the ceramic carries CEFIONTECT glaze rather than plain finish, and the 1.28 GPF one-piece and two-piece both carry EPA WaterSense certification. It suits a main bathroom or a remodel where the toilet should read as built-in rather than utilitarian.
Check Your Rough-In Before You Choose a Nexus
The Nexus takes a 12-inch rough-in as standard and a 14-inch as a paid option, and there is no 10-inch Nexus. Rough-in is the distance from the finished wall behind the tank to the center of the closet bolts at the base of the toilet, and it is the one measurement that decides whether a toilet physically fits.
Measure before you order. Find the bolt caps at the base of your current toilet, measure back to the finished wall rather than the baseboard, and use the rear pair of bolts if there are four. Twelve inches is the common size, but a reading near 10 or 14 changes what you can buy. Our rough-in size guide walks through the measurement and lists which TOTO series offer which sizes.
If your bathroom measures 10 inches, the Nexus is out and no adapter fixes it. The TOTO Aquia IV is the closest skirted alternative that offers 10-inch through TOTO's Unifit adapter. If you measure 14 inches, stay with the Nexus and add the 14-inch option at the time of order — it is fitted during installation, not added later.
How to Choose Between the Nexus Models
Four decisions separate the models on this page: one-piece or two-piece, 1.28 or 1.0 GPF, bare toilet or WASHLET+ set, and color.
One-piece or two-piece
The one-piece Nexus (MS642124CEFG) fuses tank and bowl into a single unit with no seam between them. The two-piece (MS442124CEFG) bolts a separate tank to the bowl. Both are completely skirted, both are Universal Height, both are elongated, and both flush at 1.28 GPF through the same TORNADO FLUSH system with the same SS124 SoftClose seat included. The real differences are handling and parts: a one-piece comes in as one heavy unit and has less to clean around, while a two-piece arrives as two lighter pieces and makes tank hardware easier to get at later.
1.28 GPF or 1.0 GPF
The standard Nexus uses 1.28 gallons per flush. The Nexus 1G uses 1.0 — one-piece MS642124CUFG, two-piece MS442124CUFG — with the same skirted body, glaze and flush system. The 1G uses TOTO's newer flush engineering and performs well, but very low volumes leave less margin in older plumbing, so talk to us first if your drain run is long or shallow. Otherwise it is the lowest-volume option in the series; see all 1.0 GPF toilets.
Which WASHLET pairs with the Nexus
The Nexus pairs with the WASHLET+ S2, S5, S7 and S7A. All four include EWATER+, PREMIST, a deodorizer, a warm-air dryer, a heated seat, front cleansing, and rear and soft rear cleansing, so the wash itself is not what separates them. TOTO's comparison chart lists the auto open and close lid on the S7A alone, which is the reason most people step up to it — the S7A sets open as you approach. Every WASHLET+ Nexus set is configured at order time with or without auto flush.
Color and trip lever
The bare Nexus toilets are made in Cotton, Colonial White, Bone, Sedona Beige and Ebony. Trip levers are chrome plated as standard, with polished nickel, brushed nickel and matte black offered on some models at extra cost. TOTO lists the WASHLET+ Nexus sets in Cotton, so if you need Sedona Beige or Ebony, plan on a bare Nexus plus a separate seat rather than a matched set.
