The Brondell Swash CL1700 takes everything that makes the CL1500 great and adds one crucial upgrade: a wireless remote control.
That single difference changes the entire experience, giving you more flexibility in how and where you manage your bidet settings — including the ability to pre-set your preferences before you even sit down.
It’s worth noting that the CL1700 is a Costco-exclusive model, meaning you’ll need a Costco membership to purchase it, either in-store or through Costco’s website.

Control Panel vs. Wireless Remote: Which Works Better for You?
This is the single biggest difference between these two models, and it deserves a detailed look.
The CL1500’s side-arm panel puts all controls directly on the seat — always where you expect them, no searching required.
The CL1700’s wireless remote, on the other hand, can be wall-mounted for easy access, and it lets you pre-select your settings before you sit down.
For most users, the remote wins on convenience — especially if you share the toilet with others who have different preferences and want to use the two programmable presets.
If you live alone and value simplicity, the panel is perfectly adequate and arguably less fuss.
Winner: CL1700 — the programmable remote and user presets make it more versatile for households.
Cleaning Power: Is There Any Real Difference?
Both seats use the same stainless steel self-cleaning nozzle and offer identical wash modes: rear wash, feminine wash, and strong wash.
Water pressure is adjustable across 5 levels on both models, and nozzle position is fully customizable in both cases.
One area where both seats share a common limitation: the air dryer.
Some users of the CL1700 in particular have noted that the dryer takes time and doesn’t fully eliminate the need for a quick pat-dry — a common trade-off at this price tier.
If you’re used to electric bidet seats like those covered in our guide to bidets with warm water and dryer, you’ll find both models competent but not exceptional on the drying side.
Winner: Tie — both deliver the same nozzle hardware and wash performance.
Comfort Features: Heated Seat, Deodorizer, and Nightlight
This is another area where the two models are essentially identical.
Both offer a 4-level heated seat, a carbon-block deodorizer that actively filters air rather than just spraying fragrance, and a built-in LED nightlight for nighttime trips.
These are the kind of features that move a bidet seat from functional to genuinely enjoyable — and they’re especially appreciated by anyone who has dealt with cold seats in winter months.
Seniors and users with limited mobility will also appreciate both seats for the same reasons outlined in our guide to the best bidets for seniors.
Winner: Tie — both offer the same comfort package.
Availability and Where to Buy
This is where the decision gets practical.
The CL1500 is available through standard online retail channels, making it easy to order, track, and return if needed.
The CL1700 is a Costco exclusive.
That means you’ll need a Costco membership, and if something goes wrong, you’ll be dealing with Costco’s return policy rather than a general online marketplace.
For most shoppers, this is a meaningful constraint — especially if Costco membership isn’t already part of your life.
If you’re shopping for a bidet for an existing toilet and want the flexibility to buy and return easily, the CL1500 has a clear edge here.
Winner: CL1500 — available to everyone, no membership required.
Value for Money
Both seats deliver strong value in their respective channels.
The CL1500, available through online retailers, is competitively priced for what it offers — a stainless steel nozzle, carbon deodorizer, heated seat, and nightlight at a mid-range price point.
The CL1700 at Costco often comes in at a slightly lower price point with the added benefit of the wireless remote and user presets — making it excellent value if you already shop at Costco.
For a broader look at what you can expect at this price tier, our guide to the best bidets under $500 gives useful context.
Winner: CL1700 — better features per dollar if you have a Costco membership.
Verdict — Which One Should You Buy?
Both the Brondell Swash CL1500 and CL1700 are well-made electric bidet seats with overlapping feature sets.
The right choice comes down to how you shop and how you want to control your bidet.
Buy the CL1500 if:
- You want to order online without needing a membership
- You prefer a built-in side-arm control that’s always right there when you need it
- You want easy online returns and broad retailer support
- You live alone and don’t need user presets
Buy the CL1700 if:
- You already have a Costco membership
- You want a wireless remote with programmable user presets
- Multiple people in your household will use the bidet with different preferences
- You prefer to manage settings from a wall-mounted remote
If neither of these quite fits your needs, it’s also worth checking out the best self-cleaning bidets for a wider range of options, or the full bidet toilet seat comparison chart to see how the Brondell lineup stacks up across models.
