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.
The Swash Thinline T44 is pretty low-profile, with a fairly slim seat (3.9 inches) and a subtle, streamlined appearance. Features-wise, it’s solid, with all the mainstay electric bidet features plus two user presets, an LED nightlight with a three-color range, a three-level heated seat, and a five-level warm air dryer. It also has an “eco mode,” which allows the user to reduce water and electricity usage while the unit is in use.
Unlike its fellow Brondell the Swash LS1800, the Swash Thinline T44 has a seat sensor, making a good pick for homes with children. Like other mid-range options, though, it does not have auto-open/close functionality.
The brand provides plenty of resources for self-installation; however, if you run into trouble, you can submit a support ticket (along with a photo) at the Brondell Help Center.

Thin and streamlined, this bidet toilet lid is an excellent pick for the eco-conscious buyer.
Brondell, the company behind the Swash Thinline T44, was founded in 2003 and received early backing from Mark Cuban. Environmentally minded by design, Brondell donates 1% of profits from select bidet attachments to 1% for the Planet. The T44 reflects the brand’s commitment to thoughtful, well-specified products without unnecessary complexity — and adds a design priority that distinguishes it within the electric bidet category.
As the name suggests, the Swash Thinline T44 is built around its slim profile. At 3.9 inches, it is one of the thinner bidet seats in the electric category — a meaningful quality for design-conscious buyers or those with toilets where seat height is a consideration. The low-profile look blends cleanly into most modern bathroom aesthetics without the visual bulk that some competing electric seats carry.
Feature-wise, the T44 punches solidly at its price point. A stainless steel nozzle provides durability advantages over plastic alternatives, and the self-cleaning wand rinses automatically before and after each use. Two user presets allow different household members to save and recall their preferred settings for water pressure, temperature, and nozzle position. An oscillating spray mode adds cleansing effectiveness. A warm air dryer with five adjustable levels provides a hands-free drying option after washing, and a tankless water heater ensures instant warm water with no storage tank that runs cold mid-use.
Comfort and convenience features are well-rounded: an adjustable heated seat with multiple temperature settings provides year-round comfort, and a built-in deodorizer runs during use. An LED night light with a three-color range offers convenient illumination for nighttime bathroom trips without requiring overhead lights. An eco mode manages energy consumption during periods of non-use. A seat sensor ensures the bidet activates only when someone is seated — a practical safety feature for households with children and a point of differentiation from Brondell’s LS1800 Swash model, which does not include this feature.
Controls are managed through a wireless remote, keeping the seat itself clean and uncluttered. Installation is designed for DIY setup, and Brondell provides robust self-installation resources along with a Help Center that accepts photo-based support submissions for troubleshooting. The T44 is available in both round and elongated configurations, which expands its compatibility compared to elongated-only competing models.
Like other mid-range electric bidet seats, the T44 does not include auto-open/close lid functionality. It also lacks a pulsating spray mode — buyers who want that specific massage-style wash option will need to look at other models. Brondell backs the T44 with a three-year warranty, longer than average for the category and a meaningful peace-of-mind addition.
For buyers who prioritize a slim design alongside a solid mid-range feature set — including user presets and a seat sensor — the Swash Thinline T44 is one of the more distinctive options available. It doesn’t sacrifice substance for slimness, and for those who value low profile and brand trustworthiness, it makes a well-balanced case.
