Is the Brondell Swash Thinline T22 Worth It?
Yes — for the right buyer, it absolutely is.
If you’ve been shopping the bidet toilet seat comparison chart and found yourself overwhelmed by bulky, back-heavy seats that look bolted onto your toilet, the T22 solves that problem in a way almost nothing else on the market does.
At 3.9 inches tall, it’s officially the thinnest electric bidet seat available — a claim Brondell makes confidently, and one backed by the seat’s actual measurements.
But “slim” isn’t the only thing going for it.
The instant ceramic water heater, stainless steel self-cleaning nozzle, carbon deodorizer, and 3-color nightlight put it in real competition with some of the best bidets for home use at this price tier — seats that are typically much bulkier.
The honest caveat is that this is a side-arm panel seat, not a remote-controlled one.
If you’re a multi-person household where everyone wants saved settings at a tap, the T22 isn’t built for that.
But for a single user — or a couple who shares preferences — it’s one of the most elegant, capable seats money can buy in this slim-profile category.
Design & Build Quality
The Thinline T22’s design is its most defining trait, and it lives up to the name in every way.
Measuring just 99mm — under four inches — at its highest point, it creates a seamless look on any toilet.
Where other electric seats jut up dramatically at the back, the T22 sits almost level with the bowl, giving the entire setup a cleaner, more architectural appearance.
The white finish is crisp and matte enough to resist showing water spots, and the sittable lid feels solid underfoot — a detail that matters more than most buyers realize.
One fit consideration worth knowing before you buy: the T22 requires a toilet with a relatively flat back where the tank meets the bowl at close to a 90-degree angle.
If your toilet has a curved “French curve” tank, the T22 won’t seat properly — check your toilet profile before purchasing.
Bolt hole spread also needs to fall between 5.3″ and 7.7″ for a standard install.
Both round and elongated versions are available, so compatibility with most standard North American toilets is strong — just verify the tank geometry first.

Cleaning Performance
The T22’s nozzle setup is where it earns serious credibility among fans of the best self-cleaning bidets.
The stainless steel wand automatically rinses before and after every single wash — so the nozzle you use is never the nozzle from someone else’s last use.
You get five adjustable nozzle positions along with oscillation, a gentle mode, and a stronger mode, which covers the range of what most users need day-to-day.
Water pressure and temperature are fully adjustable through the side-arm panel, letting you dial in exactly the clean you prefer.
The instant ceramic heater is a genuine standout here: there is no warm-up wait, no tank to exhaust, and no cold burst mid-wash if your session runs long.
That’s a meaningful advantage over tank-based systems, especially when compared against other seats in the best bidets with warm water and dryer category.
The activated carbon deodorizer works passively — pulling bathroom odors through an activated carbon filter at the source without spraying any chemical scents into the air.
It’s a genuinely useful feature that you’ll notice most on mornings when the bathroom would otherwise linger.
Comfort Features
The T22 delivers on the essentials that make a heated bidet toilet seat genuinely comfortable to live with.
The heated seat is adjustable and activates quickly — no cold shock when you sit down, even on winter mornings.
The warm air dryer gives you the option to go hands-free, which is the real upgrade over a cold-water-only non-electric attachment if you’re comparing those categories.
The 3-color LED nightlight (switchable between blue, red, and green) is a practical touch that makes late-night bathroom trips dramatically easier — and adds a subtle spa feel to the experience.
If nightlight functionality matters to you, this multi-color option gives you more flexibility than the single-color lights found on most competing seats.
For households with seniors or anyone who visits the bathroom frequently after dark, this feature alone is worth noting as you browse the best bidets for seniors.
Controls & Installation
The side-arm panel on the T22 is compact, clearly labeled, and intuitive once you’ve used it a few times.
For users coming from a remote-controlled seat, there’s a brief adjustment period — you reach to the side of the seat rather than picking up a handheld remote.
For first-time bidet buyers, the panel is arguably simpler: fewer buttons to lose track of, no batteries to replace in a remote, and nothing to misplace behind the tank.
Installation follows the standard electric bidet process: attach the base plate, run the T-valve connector from your water supply line, and plug into a nearby GFCI outlet.
Most users complete it in under an hour without any plumbing experience — no plumber required.
The power cord is 3.5 feet, which is standard for North American bathrooms; verify you have a GFCI outlet within reach before you order.
If you need a guide on what to look for during setup, the best bidets for existing toilets covers installation considerations across several seat types.
Who the T22 Is Best For
The T22 is the right seat if your bathroom aesthetic matters as much as your hygiene — and you don’t want a bulky seat undermining a clean, modern toilet design.
It’s especially well-suited to design-forward bathrooms, contemporary toilets with flat-back tanks, and single-user or couples’ setups where shared user presets aren’t a priority.
It’s also a strong pick if you’re considering a bidet seat over a full bidet toilet — the T22 achieves an integrated, built-in appearance without the integrated-toilet price tag.
It’s less ideal for families with multiple users who each need saved wash presets, or for anyone who strongly prefers wireless remote control.
If those features are must-haves for you, consider stepping up to the Brondell Thinline T44 (available here), which keeps the same slim 99mm profile while adding a full wireless remote and 7-color nightlight.
If the T22’s design-first approach fits your household, though, it’s one of the most refined electric bidet seats available at this profile and price point — and the 3-year warranty means you’re protected well past the point most competitors cover.

FAQ
Is the Brondell Swash Thinline T22 available on Amazon?
No — the residential T22 (T22-EW and T22-RW) is not sold on Amazon. It’s available directly from Brondell.com, as well as Home Depot, Lowe’s, and select other retailers. Only the commercial open-front version appears on Amazon, which is designed for public restrooms and not suitable for home use. If you’d prefer to buy a similarly slim Brondell seat through Amazon, the step-up Brondell Thinline T44 is available there with a wireless remote included.
Does the T22 fit both round and elongated toilets?
Yes — the T22 comes in two separate versions: T22-EW for elongated bowls and T22-RW for round bowls. Make sure you select the correct model for your toilet shape. Also confirm your toilet doesn’t have a “French curve” tank design — the T22 requires a relatively flat back where the tank meets the bowl at close to a 90-degree angle. For more on matching seats to toilet shapes, see the best bidets for round toilets guide.
What makes the T22 different from the T44?
Both seats share the same 99mm ultra-slim profile and instant ceramic water heater. The key differences are the controls and nightlight. The T22 uses a side-arm panel only, while the T44 upgrades to a full wireless remote with user memory presets. The T44 also features a 7-color LED nightlight versus the T22’s 3-color option. If remote control and preset memory are priorities, the T44 is worth the step up.
How good is the Brondell T22’s warranty?
Brondell backs the T22 with a 3-year limited manufacturer’s warranty — one of the longest in the electric bidet seat category. This covers manufacturing defects and puts it on par with top-rated seats like the Brondell Swash 1400 and competing premium models. For a seat at this price point, that coverage is a meaningful long-term value.
Conclusion
The Brondell Swash Thinline T22 is one of the most thoughtfully designed electric bidet seats I’ve reviewed.
The 3.9-inch profile is genuinely transformative for how a bidet seat looks on a toilet — it’s the seat you reach for when you want hygiene tech that doesn’t announce itself the moment someone walks in the bathroom.
The instant ceramic heater delivers truly endless warm water, the stainless steel nozzle auto-rinses reliably, and the carbon deodorizer makes a noticeable difference in bathroom freshness.
The trade-off is real: no wireless remote, no user presets, and it’s not sold on Amazon.
But if those aren’t dealbreakers for you, the T22 is a genuinely excellent seat backed by a 3-year warranty and a brand with a long track record.
