DeerValley has been a quiet player in the residential plumbing space, and the 1S0019 is their bid for the smart toilet mainstream. It skips the gimmicks and focuses on the one feature that changes daily comfort: a heated seat. The four-level temperature adjustment is straightforward to toggle, and the constant heating system means you won’t sit down to a cold ceramic surprise. For winter mornings, that alone justifies the upgrade.

The elongated one-piece ceramic body is floor-mounted and follows a clean U-shape. The automatic flush handles itself after you stand up, which removes a step from the routine. The bidet function is integrated into the seat, with a standard rear wash that uses the existing water line. It’s not a feature-packed remote-control unit with dozens of spray patterns. It’s a reliable, heated seat with a flush sensor that works consistently.

The main trade-off is simplicity. There’s no oscillating nozzle, warm air dryer, or deodorizer. You get what’s listed: a heated seat, automatic flush, and a bidet. The ceramic is standard white and cleans easily. If you want a smart toilet that doesn’t require a manual or a learning curve, this DeerValley delivers the core experience without the extra complexity.
