Is the Brondell Swash LT89 Worth It?
Yes — the Swash LT89 is absolutely worth it for the buyer who wants a genuine electric bidet experience without stepping into premium territory.
You get a full stainless-steel self-cleaning nozzle, a hybrid warm water system, six wash modes, and a heated seat — features that typically cost considerably more.
The one honest trade-off is the missing warm air dryer.
If a completely paper-free experience is your goal, you’ll want to step up to the LE89 or LE99, which add the dryer and wireless remote.
But if you’re fine patting dry and you want to stretch your budget further on the wash experience itself, the LT89 delivers surprisingly strong performance — outperforming several more expensive models in actual spray power according to hands-on comparisons.
For a deeper look at how this seat fits into the broader market, the bidet toilet seat comparison chart on this site is a great resource to bookmark.
Design & Build Quality
The LT89 sits low and sleek on the toilet — at just 5.7 inches tall at the rear, it maintains a slim profile that doesn’t look clunky or oversized.
The white finish is clean and neutral, and the overall construction feels solid for its price class.
The side-arm control panel extends from the right side of the seat and houses all the buttons you need — wash mode, pressure, temperature, nozzle position, and eco mode.
It’s a compact panel, and while it requires a bit more reach than a wireless remote, most users adjust quickly.

The quick-release tab makes it easy to remove the entire seat for deep cleaning — a feature worth appreciating when you’ve owned a bidet for a year or two.
The slow-close seat and lid prevent slamming, and the soft-close hinges feel smooth and well-engineered for this price range.
Compared to bidet seats that come with exposed wiring and a bulky tank at the back, the LT89 keeps things relatively clean-looking — a minor aesthetic win in a bathroom where details matter.
If design is your top priority, the Brondell Swash 1400 vs TOTO Washlet S5 comparison explores what a more premium aesthetic upgrade looks like at a higher price point.
Cleaning Performance
This is where the LT89 genuinely earns its stripes.
The full stainless-steel nozzle is the headline hygiene feature — it covers the entire wand, not just the tip, making it more durable and more resistant to bacterial buildup than partial-steel or plastic designs you’ll find on competing seats.
The nozzle automatically self-rinses before and after every use, and you can also trigger a manual nozzle clean from the side panel.
With 5 adjustable nozzle positions, you can dial in the exact spray angle for front or rear wash.
The Strong Wash Mode delivers a noticeably more powerful blast when you want a deeper clean — and the oscillating and pulsing spray options add variety and coverage that basic bidet seats completely lack.
Front and rear washes are naturally aerated, which softens the stream and makes the overall sensation more comfortable without sacrificing cleaning power.
If you want to understand exactly why stainless-steel nozzles matter for daily hygiene, the guide to the best self-cleaning bidets breaks it down clearly.
Warm Water & Comfort Features
The LT89 uses what Brondell calls a hybrid heating system — a combination of a small heated tank that delivers warm water immediately, plus on-demand heating that extends the warm session beyond what a standard tank-only system can manage.
In practice, this means you get warm water from the first second of your wash, and it stays warm for an extended cycle — unlike budget tank heaters that go cold after 30–40 seconds.
The heated seat comes with 3 temperature levels, and the eco mode reduces energy consumption when the seat isn’t in active use.
The soft blue LED nightlight is a small but genuinely useful touch — it makes late-night bathroom visits much more comfortable without flipping on the overhead light.
What the LT89 does not include is a warm air dryer.
This is the key trade-off versus the LE89 — which adds a dryer and is otherwise nearly identical.
If going completely paper-free is important to you, the best bidets with warm water and dryer guide will point you toward the right models.
Controls & Installation
The LT89 is controlled entirely via the side-arm panel — there is no wireless remote option for this model.
The controls are well-labeled and logically laid out, making it easy to learn within the first few uses.
If you’ve been considering a remote-controlled seat, the LE99 (which adds both a dryer and a wireless remote) is the next natural step up in the Brondell lineup — covered in the best bidets for existing toilets roundup.
Installation is genuinely DIY-friendly.
The LT89 comes with a 7/8-inch metal T-valve and a 25-inch braided metal bidet hose — all the hardware you need for a standard installation.
You’ll remove your existing toilet seat, attach the mounting plate, connect the T-valve to your water supply, and plug the seat into a standard GFCI outlet.
Most people complete this in under 30 minutes without any tools beyond a standard wrench.
The bolt spread is adjustable between 5.25 and 7.45 inches, which covers the vast majority of North American toilets.

Who Is the Brondell Swash LT89 Best For?
The LT89 is ideal for first-time bidet buyers who want a meaningful upgrade from a basic attachment without committing to a premium price.
It’s also a strong choice for households with a single bathroom user who doesn’t need wireless remote convenience or saved user presets.
If you’re shopping for a bidet for a round toilet, the LT89-RW (B084T99LZD) is available in round and shares all the same features as the elongated version.
For seniors or users who prioritize ease of use, the remote-controlled LE99 may be more accessible — our guide to the best bidets for seniors walks through the key considerations.
If your budget allows for the step up, comparing the LT89 to the Brondell CL1700 or the best bidets under $300 can help you calibrate whether the extra spend is worth it for your specific needs.
FAQ
Does the Brondell Swash LT89 have a warm air dryer?
No — the LT89 does not include a warm air dryer.
If you want a dryer, Brondell’s LE89 is the closest alternative — it’s nearly identical but adds a warm air dryer and keeps the side-arm control.
The LE99 adds both a dryer and a wireless remote if you want the full upgrade.
Does the LT89 fit round toilets?
Yes — the LT89 is available in both elongated (LT89-EW) and round (LT89-RW) versions.
The round version measures 19.5″ x 18.5″ x 5.7″ and fits most standard round toilet bowls.
The bolt spread adjusts between 5.25 and 7.45 inches to accommodate different toilet models.
How does the LT89’s hybrid heater compare to a tankless heater?
A tankless heater starts heating water only when you activate the wash, which means the very first second can feel slightly cool before it warms up.
The LT89’s hybrid system starts with a small pre-warmed tank so the water is warm from the first moment, then extends the warm session with on-demand heating — giving you a longer warm water cycle than a pure tank heater without the initial cold start of a tankless-only model.
How does the Brondell Swash LT89 compare to the TOTO Washlet S2?
The LT89 and the TOTO S2 are close in price, but they take different approaches.
The TOTO S2 adds EWATER+ nozzle sanitization and PREMIST bowl coating — hygiene technologies the LT89 doesn’t offer.
The LT89 counters with a full stainless-steel nozzle, oscillating spray, and a Strong Wash Mode that the S2 lacks.
The CL1700 vs TOTO S2 comparison explores the Brondell vs TOTO dynamic in more depth if you’re weighing brands.
Conclusion
The Brondell Swash LT89 is one of the most feature-complete electric bidet seats you can buy at its price point.
A full stainless-steel nozzle, six wash modes including oscillating and pulse, 5-setting water temperature and pressure control, a hybrid heater that actually stays warm, and a convenient LED nightlight — this is a lot of bidet for the money.
The honest trade-offs are the missing warm air dryer and no wireless remote — but those are conscious design choices that allow Brondell to price the LT89 where they do.
If those features matter to you, the LE89 or LE99 are natural upgrades in the same product family.
For first-time bidet buyers and anyone looking to maximize features per dollar, the LT89 is a confident recommendation.
