Moen Bia Bidet Seat Overview

The Moen Bia bidet seat line launched to compete with mid-range Toto Washlet models. Bia seats use an in-line water heating system rather than a reservoir tank, delivering continuous warm water without a pre-warm wait. The slim-fit design keeps the seat close to standard toilet height, and the side control panel is intuitive for first-time bidet users.

Top Moen Bia Models Compared

Moen Bia Elongated Bidet Seat (Model EB2-RCS): The flagship Bia elongated model includes five water temperature settings, three spray width adjustments, a heated seat with five temperature levels, and a warm air dryer. The posterior and feminine wash modes are separate nozzle positions. Retail price ranges from $280 to $320.

Moen Bia Round Bidet Seat: Identical feature set to the elongated version in a compact footprint for round-bowl toilets. Ideal for smaller bathrooms where elongated bowls are impractical. Pricing is slightly lower at $260 to $300.

Compared to the Toto Washlet C2, the Moen Bia offers a comparable heated seat and spray system at a similar price point, with Moen's broader retail distribution giving it an edge for in-store availability.

How Moen Bia Rates on Key Comfort Features

Water pressure on the Bia is adjustable across five settings, from a gentle rinse to a more vigorous clean. The oscillating spray function moves the nozzle back and forth automatically, which many users prefer over a fixed stream. The heated seat responds quickly -- most reviewers note the seat feels warm within 90 seconds of sitting. The dryer function is effective though slower than higher-end Toto or Brondell models.

Moen Bia vs. Competing Mid-Range Bidet Seats

Against the Bio Bidet Slim TWO and the Brondell Swash 1400, the Moen Bia holds its own on water heating consistency. Where Moen lags is nozzle self-cleaning -- the Bia uses a basic pre-rinse cycle while the Brondell Swash 1400 has a silver nano-particle coating. For most households the Bia cleaning is sufficient. Moen's warranty support and parts availability through its existing plumbing network is a notable advantage.

Which Moen Bidet Seat to Buy

For elongated toilets in a primary bathroom, the Moen Bia EB2-RCS delivers the most complete feature set. Households prioritizing budget over dryer features should consider the entry Bia model, which omits the warm air dryer but retains heated water spray and a heated seat. Both models install without tools beyond a basic adjustable wrench.
