TOTO June 2026 New Products: Washlets, Toilets, and Sinks

TOTO has just released its June 2026 new product book, and it's one of the more expansive drops the brand has put out in a single cycle. The lineup spans residential Washlets, a new integrated smart toilet, an expanded color run for the Nexus one-piece, new undermount lavatories, a fresh bathroom accessories collection, and a significant push into commercial plumbing.

Products are available for order starting July 1, 2026, with shipping beginning August 3, 2026.

If you've been tracking TOTO's trajectory since the Aurora, Redington, and Glaston releases earlier this year, this new batch fits right in with that same focus on clean design, smarter hygiene technology, and water efficiency that the brand has been building toward. Here's a full look at what's new!

Washlet S1: A Clean Entry into TOTO's Bidet Seat Lineup

The S1 Washlet is TOTO's entry-level offering in this June release, and it covers the fundamentals well. It's an electronic bidet seat available in both elongated and round configurations, and it fits the WASHLET+ system, meaning the power supply and water line connections can be routed inside compatible TOTO toilets for a cleaner install.

The S1 includes front and rear warm water cleansing with aerated flow, plus oscillating and pulsating spray options. Spray position, water temperature, and pressure are all adjustable. The seat itself is heated with temperature control, and the seamless design closes up the gap where dirt and moisture tend to collect on standard seats. A SoftClose lid, arm-mounted control panel, auto energy saver mode, and a docking station for easy removal round out the package.

Two things that set TOTO's Washlets apart at every tier are CLEAN RESIN and the self-cleaning wand. The CLEAN RESIN coating on the wand and seat surface resists buildup and makes daily maintenance significantly easier. The wand cleans itself inside and out before and after every use, so there's no manual cleaning routine required to keep things hygienic.

TOTO’s S1 uses an instantaneous water heater rather than a tank, which keeps energy consumption low and ensures continuous warm water throughout the cleansing cycle without waiting for a reservoir to refill.

Washlet KS2: A Mid-Tier Step Up with a Night Light and Warm Air Dryer

The KS2 Washlet is an e-commerce exclusive product available in elongated and round. It builds on the S1 with two notable additions: a warm air dryer with three variable temperature settings and a night light that illuminates the inside of the bowl.

The dryer is a practical feature that makes a real difference in day-to-day use. The bowl night light is subtle but useful, particularly in bathrooms where people prefer not to flip on overhead lighting during nighttime visits.

Everything else in the KS2 matches the S1's core feature set: CLEAN RESIN, self-cleaning wand, aerated warm water front and rear spray, adjustable settings, arm control panel, heated seat, seamless design, SoftClose seat, docking station, and the auto energy saver mode.

Like the S1, the KS2 also uses an instantaneous water heater and fits the WASHLET+ system.

Washlet KS5: The Top-Tier Seat in This Release

The KS5 Washlet is another e-commerce exclusive and sits at the top of the three Washlet options in this release. It's available in round configuration only, and it adds a multifunction remote control with personalized memory settings for up to four users, which is the most meaningful upgrade over the KS2.

The remote gives each household member the ability to save their preferred spray position, temperature, and pressure settings so the seat automatically delivers their preferred experience without any manual adjustments. That's a practical feature in households with multiple users who have different preferences.

All other features from the TOTO KS2 carry over: warm air dryer with three temperature settings, bowl night light, self-cleaning wand with CLEAN RESIN, heated seat, seamless design, SoftClose lid, docking station, auto energy saver, and WASHLET+ compatibility. The KS5 is listed as compatible with most round toilets, so it's not limited to TOTO fixtures.

Washlet G5A Lite Integrated Smart Toilet: The Full Package in One Unit

The WASHLET G5A Lite Integrated Smart Toilet is a compact, modern one-piece skirted smart bidet toilet that integrates the flush system, bidet seat, and all associated technology into a single unit.

This is a fully loaded product. The G5A Lite uses TOTO's TORNADO FLUSH system at 1.2/1.0 GPF, with an electronically controlled flush valve that optimizes water flow for both cleaning performance and quiet operation. CEFIONTECT ceramic glaze on the bowl minimizes waste adhesion. Auto flush is included, with a backup manual flush for power outages. The seat lid opens and closes automatically via touchless sensor, and the unit meets universal height and ADA compliance standards.

On the cleansing side, the G5A Lite brings EWATER+ into the mix. EWATER+ is electrolyzed water that TOTO uses to mist the wand and bowl after each use, reducing the need for chemical cleaners. PREMIST automatically mists the bowl surface before each use, which significantly reduces waste adhesion compared to a dry bowl. The unit also includes CLEAN LIFT, a feature that allows easy cleaning access between the top unit and the bowl body.

The feature set also includes a multifunction remote with four-user memory settings, front and rear warm water cleansing with oscillating and pulsating options, warm air dryer with three temperature settings, automatic air deodorizer, instantaneous water heater, heated seat, seamless design, SoftClose lid, and programmable energy saving systems.

Nexus One-Piece Toilet: Now Available in Four Matte Colors

The TOTO Nexus One-Piece Toilet is one of the most visually striking additions in this release.

The Nexus has a completely skirted design that conceals the trapway behind smooth porcelain, giving it a sleek, understated profile that's also easier to clean than exposed-trapway alternatives. It uses TOTO's TORNADO FLUSH system at 1.28 GPF/4.8 LPF, which is WaterSense certified, and CEFIONTECT ceramic glaze is applied to the bowl surface.

The matte white, matte black, matte grey, and matte beige finish range reflects where residential bathroom design has been heading. These finishes reduce glare, hold up well in high-traffic bathrooms, and coordinate cleanly with a wide range of tile, vanity, and hardware combinations.

Rectangle Undercounter Lavatories: Multiple Sizes, Clean Design

TOTO's new Rectangle Undercounter Lavatories are rimless, vitreous china undermount sinks with a clean rectangular profile and front overflow. They're available in sizes 17-11/16" W x 13" D and 19-11/16" W x 13" D.

All the units feature CEFIONTECT ceramic glaze on the basin surface, which resists debris and mold adhesion and reduces the amount of cleaning product needed to keep the sink looking clean. Each comes with mounting hardware including an installation template and mounting screw set for wood countertops, and all three are ADA compliant.

The rimless rectangle design works well in contemporary bathroom builds and remodels where the countertop material is meant to be visible. Since these drop below the counter surface, the sink itself becomes secondary to the counter plane, which suits the current preference for uninterrupted countertop runs in vanity design.

How to Order TOTO's New 2026 Products

Products are available for order starting July 1, 2026, with shipping beginning August 3, 2026.
