The Brondell Swash 1400 is the flagship of the Swash lineup — and it earns that title with a feature set that genuinely competes with seats twice its price.

2. Brondell Swash CL1700 (CL1700-EW)
The Brondell Swash CL1700 packs an impressive array of luxury features into a more accessible package — stainless-steel nozzle, wireless remote, warm air dryer, carbon deodorizer, and LED nightlight all included.
It was originally developed as a Costco-channel exclusive, and that heritage shows in its exceptional value-for-money positioning; you get a genuinely well-rounded electric bidet seat without paying flagship prices.
Features
- Single stainless-steel nozzle with self-cleaning rinse and 5 adjustable positions
- Hybrid heating system — long-lasting warm water that doesn’t run cold mid-wash
- Posterior wash, feminine wash, strong wash, gentle wash, pulse, and oscillation modes
- Heated seat with 4 warmth levels
- Warm air dryer with 5 temperature levels
- Replaceable carbon deodorizer — traps odors at the source, no masking fragrance
- LED nightlight with on/off option
- Wireless remote with magnetic wall-mount dock
- 2 programmable user presets
- Gentle-close seat and lid, quick-release for easy cleaning
- Available elongated and round, white only
- 1-year limited warranty
Pros
- Hybrid heating delivers warm water consistently — most users report no cold water surprises
- Five-level warm air dryer is more granular than the Swash 1400’s dryer settings
- Carbon deodorizer is an active air-cleaning system, not just a fragrance
- Wireless remote with magnetic dock is intuitive and well-designed
- Strong wash mode offers added cleaning power when you need it
- Priced lower than the Swash 1400 — strong value for a feature-complete electric seat
Cons
- Single nozzle serves both rear and front wash — less hygienically discrete than a dual-nozzle design
- Only 5 nozzle positions vs. 7 on the Swash 1400 — slightly less precision targeting
- 1-year warranty is the weakest point — short coverage for a premium bathroom appliance
- White only — no biscuit or alternative color option
- Some reviews note the dryer output is on the weaker side
If you want a full-featured electric bidet seat with a great remote, active deodorization, and solid warm water delivery — without stepping up to the Swash 1400’s price — the CL1700 is an excellent choice.
It’s a natural comparison to many seats covered in the best bidets for existing toilets guide and holds its own very well.

Warm Water: Ceramic Core vs. Hybrid Heating
This is the first place the two seats diverge in a way that actually affects your daily experience.
The Swash 1400 uses a ceramic core heating system — a small reservoir of water kept continuously warm by a ceramic heating element.
It’s fast, reliable, and has been the signature of Brondell’s warm water delivery for years.
The CL1700 uses a hybrid system, pairing a small reserve tank with a secondary heating coil to extend the warm water duration.
In practice, both seats deliver warm water for the full wash cycle for most users.
The Swash 1400 has a slight edge on pure consistency — but the CL1700’s hybrid system largely closes the gap and some users actually prefer it because it avoids the very brief cool-water burst that a minority of Swash 1400 users report at nozzle activation.
Winner: Swash 1400 — ceramic core warm water is the more proven and dependable system, though the CL1700 is a close second for most everyday users.
Nozzle Design: Dual vs. Single
This is the biggest functional difference between the two seats — and it matters most for women’s hygiene.
The Swash 1400 features two completely separate stainless-steel nozzles: one dedicated to rear wash, one to front feminine wash.
Each nozzle handles its own function without ever being used for the other — a meaningfully more hygienic setup.
The CL1700 uses a single stainless-steel nozzle that extends to different positions for rear and front wash.
The nozzle self-rinses before and after use, which keeps it clean — but it’s a shared delivery mechanism, which some users are simply not comfortable with.
The 7 adjustable positions on the Swash 1400 also give you noticeably more targeting precision than the CL1700’s 5 positions.
If you’ve been comparing seats on the best bidets for women list, you’ll recognize why dedicated dual nozzles are consistently highlighted as a hygiene advantage.
Winner: Swash 1400 — dual dedicated nozzles are more hygienic and more precise, especially for feminine wash.
Wash Modes and Comfort Features
The CL1700 actually edges ahead here.
It offers posterior wash, feminine wash, strong wash, gentle wash, pulse, and oscillation — a broader menu of wash experiences than the Swash 1400’s standard modes.
Both seats include a heated seat, warm air dryer, LED nightlight, and wireless remote with programmable presets.
Where the CL1700 also pulls ahead slightly is dryer levels — five temperature settings vs. the Swash 1400’s standard dryer.
Both seats include a carbon deodorizer and a one-touch auto mode for hands-free wash and dry cycles.
If you prioritize variety in your wash experience and fine-grained dryer control, the CL1700 delivers more options at each interaction.
For a broader look at how these comfort features stack up across the market, the best heated bidet toilet seats guide is a great companion read.
Winner: CL1700 — more wash modes and more dryer temperature levels give you greater day-to-day customization flexibility.
Warranty and Long-Term Value
This category isn’t close — and it’s one of the most important factors when spending serious money on a bathroom appliance.
The Swash 1400 comes with a 3-year limited manufacturer’s warranty.
The CL1700 comes with just a 1-year limited warranty.
For a product installed permanently in your bathroom and used multiple times daily, two extra years of coverage against defects and component failures is genuinely significant protection.
Both seats install similarly — DIY-friendly, under an hour, no plumber needed, just a nearby GFCI outlet.
The Swash 1400 has a 3.5′ power cord; the CL1700 has a 3.9′ cord — giving the CL1700 a slight edge if your outlet is positioned further from the toilet.
If long-term peace of mind is part of your buying equation — and it should be — the Swash 1400’s warranty advantage is hard to ignore.

Winner: Swash 1400 — 3-year warranty is a clear and meaningful advantage.
Verdict — Which One Should You Buy?
Both seats are excellent Brondell products — but they serve genuinely different buyers.
Buy the Brondell Swash 1400 if:

- Long-term warranty coverage matters to you — 3 years vs. 1 year is a real and significant difference
- You want the most nozzle positioning options (7 vs. 5) for precise, comfortable targeting
- Your bathroom has biscuit-colored fixtures and you need a matching seat

FAQ
Is the Brondell CL1700 still a Costco exclusive?
The CL1700 was originally developed as a Costco-exclusive model, but it is now available through additional retail channels including online listings.
If you’re a Costco member, it’s worth checking their pricing as it can be competitive — but it is no longer exclusively available there.
Does the Swash 1400 have a stronger dryer than the CL1700?
Both dryers deliver warm airflow but neither is the most powerful in the market — a common trade-off across most bidet seats at this price tier.
The CL1700 actually offers five dryer temperature levels vs. the Swash 1400’s standard dryer options, giving you more granular control of the drying experience.
If the strength of the warm air dryer is your top priority, comparing both models against the best bidets with warm water and dryer guide will give you a more complete picture.
Which seat is better for round toilets?
Both the Swash 1400 and CL1700 are available in round toilet versions — so neither has a compatibility advantage here.
Always verify your bowl shape before purchasing: measure the distance from your bolt holes to the front of the bowl — under 18″ is round, 18″–19.5″ is typically elongated.
For more options, the best bidets for round toilets guide covers multiple brands.
Can the Swash 1400 or CL1700 replace toilet paper entirely?
Yes — both seats include a warm air dryer, which means you can wash and dry completely hands-free without using any toilet paper at all.
The does a bidet replace toilet paper article explains exactly how that works in everyday use.
