Brondell was founded in 2003 and received an early investment from Mark Cuban. It’s an environmentally-minded company that donates 1% of its profits on select bidet attachments to 1% for the Planet, a nonprofit that supports vetted environmental organizations.
One of its bestselling bidet toilet lids is the LS1800-RW Swash, a mid-range electric option that’s streamlined in design and pretty feature-rich for the price. You’ll get classic features like a heated seat, a warm air dryer, a deodorizer, and a self-cleaning nozzle, as well as more premium features—like two user presets and an LED nightlight with a seven-color (!) range. The brand asserts that self-installation should take under an hour; however, if you run into trouble, you can submit a support ticket (along with a photo) at the Brondell Help Center.
Unfortunately, the Swash LS1800-RW only comes in a version to fit round toilets and does not have auto-open/close capabilities. It also lacks a seat sensor, making it a less suitable choice for homes with children. For an adult-only home, however, it’s a solid pick.
This is an electric bidet seat and requires a nearby grounded outlet to function.
Includes a warm air dryer for a hands-free drying experience after washing.
The lid does not open or close automatically.
Does not include a seat sensor. The bidet can be activated whether or not someone is seated.

A nice mid-range option from an environmentally-minded brand, though it lacks a seat sensor and auto-open/close functionality.
The Brondell Swash LS1800-RW is a mid-range electric bidet seat that punches above its weight in both features and design. Made by Brondell—a company founded in 2003 that received early backing from Mark Cuban—the LS1800-RW reflects the brand’s long-standing focus on accessible, thoughtfully designed bathroom upgrades. Brondell also positions itself as environmentally minded, donating 1% of profits from select bidet attachments to 1% for the Planet, a nonprofit that supports vetted environmental organizations.
In terms of core functionality, the LS1800-RW delivers the essentials most people expect from a premium bidet seat. It offers warm water cleansing, a heated seat, and a warm air dryer, making it comfortable year-round. The self-cleaning stainless steel nozzle rinses automatically before and after use, helping maintain hygiene with minimal effort from the user. A built-in deodorizer helps neutralize odors during use, which is a feature not always included at this price point.
Where the Swash LS1800-RW really stands out is in its customization. Unlike many mid-range models, it includes two user presets, allowing different users to save their preferred water temperature, spray pressure, and nozzle position. This makes it a more convenient option for shared bathrooms. The wireless remote control is intuitive and clearly labeled, making it easy to adjust settings without leaning or reaching. An LED nightlight adds extra convenience for nighttime bathroom trips, and the fact that it offers a seven-color range is a fun, slightly unexpected bonus.
Design-wise, the LS1800-RW has a streamlined, modern profile that doesn’t look bulky on the toilet. While it’s not the slimmest bidet seat on the market, it strikes a nice balance between comfort and aesthetics. This particular version also only fits round (not elongated) toilet seats. Brondell states that self-installation should take under an hour for most users, and the process is generally straightforward if you already have access to a nearby electrical outlet. If installation issues arise, Brondell’s Help Center allows customers to submit support tickets along with photos, which can be helpful for troubleshooting.
There are a few limitations to keep in mind. The LS1800-RW does not include automatic lid open/close functionality, which is something some higher-end models offer. It also lacks a seat sensor, meaning the bidet can technically be activated without someone seated. That makes it a less ideal choice for households with small children, where accidental activation is more likely.
Brondell backs the Swash LS1800-RW with a three-year manufacturer warranty, which is solid for a mid-range electric bidet seat. For adult-only households or users who value customization, comfort, and thoughtful extras like presets and night lighting—without stepping into luxury-price territory—the LS1800-RW is a well-rounded and reliable option.
