The TOTO Washlet T1SW2491 is an elongated electronic bidet toilet seat that transforms your bathroom experience with premium cleansing comfort and hygiene features. This advanced bidet seat features gentle aerated warm water with adjustable dual-action spray, offering both oscillating and pulsating cleaning modes with customizable water temperature (95-104°F) and pressure settings.

The heated seat provides consistent warmth coverage with adjustable temperature control (82-97°F), while the soft-close lid ensures quiet, gentle closing. The self-cleaning wand automatically sanitizes itself before and after each use, and the strategic water stream angle prevents splash-back. PREMIST technology uses the incoming water supply to mist the toilet bowl before each use, preventing waste adhesion and keeping the bowl cleaner longer.

Additional comfort features include a warm air dryer with three variable temperature settings (95-140°F) that reduces toilet paper dependency, and an automatic air deodorizer with filter system that neutralizes bathroom odors. The wireless remote control offers 4-user personalized memory settings for customized preferences. Quick-release feature allows easy detachment for thorough cleaning of both the seat and toilet.

Technical specifications include 120V AC 60Hz operation with a 3.9-foot three-prong power cord requiring a 15-amp GFCI outlet (surge protection recommended). Water pressure requirements range from 7.25 PSI minimum to 108.78 PSI maximum, with rear spray using 0.07-0.11 gallons per minute and front spray using 0.08-0.11 gallons per minute. The unit measures 18.63 inches wide by 6.63 inches high by 20.94 inches deep and weighs approximately 17 pounds.

Installation is designed for do-it-yourself setup and fits most standard elongated toilet designs, though it may not accommodate fully skirted bowls or models restricting fill valve access. Adequate tank space is required for the tee connector and water connection. TOTO is trusted by over 60 million Washlet users worldwide for dependable, high-quality bidet seats with long-lasting performance.
