When delving into the world of electronic bidet toilet seats, TOTO stands out as a leading brand known for its innovation and quality. Among its diverse offerings, two models frequently come into question for consumers: the TOTO SW3084#01, commonly found on platforms like Amazon, and the TOTO T1SW2491#01, a specific model available at Costco. While both are TOTO Washlets designed for elongated toilets and share many core functionalities, crucial differences in their feature sets, technological inclusions, design, and pricing strategy set them apart. This comprehensive analysis will explore these distinctions to help you make an informed decision.
Understanding the model numbers is the first step in distinguishing these Washlets. The TOTO SW3084#01 is widely recognized as the TOTO Washlet C5. This model is part of TOTO's more broadly distributed line, available through various major retailers. In contrast, the TOTO T1SW2491#01 is typically an exclusive offering for Costco, often referred to as a "Costco exclusive" or "Costco-branded version" of a TOTO Washlet. While it carries the TOTO name and quality, its feature set is specifically curated for the Costco market.
Both the SW3084#01 and T1SW2491#01 provide a luxurious and hygienic cleansing experience, sharing several fundamental features that are hallmarks of TOTO Washlets:
Both models offer a comfortably heated seat, allowing users to adjust the temperature to their preference, providing warmth during colder months.
A core function of any bidet, both units provide a gentle, aerated warm water cleansing. Users can customize the water temperature, pressure, and position of the spray for optimal comfort and cleanliness.
These Washlets include both oscillating (back-and-forth movement) and pulsating (gentle, rhythmic pressure variation) spray modes, ensuring a thorough and soothing cleanse.
To reduce reliance on toilet paper, both models incorporate a warm air dryer with adjustable temperature settings, promoting a more eco-friendly and comfortable experience.
An integrated automatic air deodorizer with powerful air filters helps to neutralize odors in the bowl, contributing to a fresher bathroom environment.
Both Washlets utilize PREMIST, which sprays a fine mist of water onto the toilet bowl's surface before each use. This creates a slick surface that helps prevent waste from sticking, making the bowl easier to clean and maintain its pristine condition.
Both models are equipped with a SoftClose lid, which gently closes to prevent slamming and reduce noise, enhancing the overall user experience.
As indicated by their product descriptions, both are designed to fit standard elongated toilets, ensuring broad compatibility with most modern toilet bowls.
While many features are shared, the most significant distinctions lie in advanced technologies and design elements. The primary difference centers around TOTO's proprietary EWATER+ technology and the sophistication of the remote control.

The TOTO SW3084#01, or C5 Washlet, is positioned as a more premium offering, incorporating advanced features for enhanced hygiene and user convenience:
This is the most significant differentiating factor. The SW3084#01 includes EWATER+ (electrolyzed water) technology, which automatically cleans the wand before and after each use by misting it with electrolyzed water. This process helps to disinfect the wand, reducing bacteria and buildup without the need for harsh chemicals. Some sources also indicate EWATER+ helps clean the toilet bowl itself, further boosting hygiene.
The C5 model is noted for its sleeker, slimmer profile compared to older TOTO Washlet iterations, offering a more modern aesthetic that integrates seamlessly with contemporary bathroom designs.
The SW3084#01 comes with a slim, wireless remote control featuring an illuminated touchpad. A key advantage here is the inclusion of two user memory settings, allowing multiple users to save their preferred water temperature, pressure, and spray positions for quick recall, personalizing the experience.
The TOTO T1SW2491#01, while robust in its features, typically omits the EWATER+ technology, allowing it to be offered at a more competitive price point through Costco. It aims to deliver core TOTO quality and features for a broader market:
This is the primary trade-off for the lower price. The T1SW2491#01 relies on a standard self-cleaning function for the wand, which cleans it with regular water before and after use, but it lacks the advanced disinfection provided by EWATER+.
This model is specifically retailed by Costco, often featuring competitive pricing that can be significantly lower than the SW3084#01. Its availability is typically tied to Costco's inventory cycles and membership benefits.
While it includes a "luxury remote control," it may not offer the same level of advanced customization or user preset memory functions found on the C5's remote. It provides essential controls but might be less feature-rich in comparison.

Its refined remote with user presets also contributes to a seamless and personalized experience.
The T1SW2491#01 from Costco receives high marks for offering the essential benefits of a TOTO Washlet—heated seat, warm water wash, air dryer, and PREMIST—at a very attractive price point. Users who don't consider EWATER+ a critical feature will find this model to be an exceptional value, providing a significant upgrade from a traditional toilet seat without the premium price tag.
