【Comfort & Compatibility Guide】Elongated V-shaped design fits most toilet seat elongated bases—round, oval, and elongated—not compatible with square bases. Offers 3 everyday wash modes (Front, Rear, Self-Clean). Customize your experience with 4-level water temp, seat temp, air drying, and adjustable 4-level water pressure for comfortable, personalized care. 【AUTO One-Touch Comfort】Unlike most electric bidets that need two steps, our smart bidet toilet seat [AUTO] mode completes the full Rear Wash + Warm Air Dry with one tap—just sit and relax. The side color knob also lets you easily choose Rear Wash, Front Wash, Dry, or Stop. Both controls stay simple for seniors, pregnant women, and kids. 【10-Minute Easy Installation】Set up your heated bidet toilet seats in about 10 minutes—no professional help required. Remove the old seat, place the alignment guide, install the brackets, slide the seat into position, connect water and power, and enjoy upgraded comfort. Comes with G7/8 & G3/8 T-valves compatible with most U.S. home water supplies. 【Silent & Steady Warmth】The slow close heated toilet seat lid drops quietly—under 25 dB, no sudden slams. The heated seat stays comfortably warm, while instant heating delivers warm water and warm air right away, keeping you free from cold shocks in any season. 【Modern Tech, Cozy Ambiance】Elevate your bathroom with a sleek design featuring ambient halo lighting, a clear LED temperature display, and a colorful function knob. The soft glow makes nighttime use easy and enjoyable, adding a touch of modern fun to your routine.
