Item #1996587 | Brondell Swash CL150 Elongated Non-Electric Bidet Toilet Seat | Price: $59.99 on sale ($20 off, regular $79.99) | Check current pricing — this product frequently goes on sale with $20 off.
I posted this bidet at Costco and the response was overwhelming — turns out people have very strong opinions about washing their butt. Here’s my honest take plus what real buyers are saying. Some love them. Some are terrified. And a surprising number of people bought this exact model and came back to tell me about it.
Here’s everything you need to know before you buy, sourced from real buyers, 200+ TikTok comments, and 20 Costco product reviews.
What You’re Getting
The Brondell Swash CL150 is a non-electric bidet toilet seat that replaces your existing toilet seat entirely. It’s not a bidet attachment that goes under your seat — it is the seat. That distinction matters because it looks significantly cleaner and more integrated than the $25 Amazon attachments that several commenters compared it to.
Key features: dual self-cleaning retractable nozzles (front and rear wash), fully adjustable water pressure via a chrome dial on the side, gentle-close seat and lid, quick-release button for easy cleaning, and a sleek wrap-over lid design that hides all the plumbing.
It fits elongated toilets only — not round. Multiple commenters and reviewers confirmed this is elongated-specific, so measure your toilet before buying.
The Price Breakdown
At Costco in-store, the CL150 is on sale for $59.99 (regular $79.99, $20 manufacturer’s instant rebate valid through 5/31/26). Online at Costco.com, the price is $69.99 with the same $20 off.
For context, the CL150 retails for $99.99 on Brondell’s own website. So the Costco sale price is 40% off retail — a significant deal.
Several TikTok commenters pointed out that you can get basic bidet attachments on Amazon for $15-25. That’s true, but those are attachments that go under your existing toilet seat, not full seat replacements. They don’t have the sleek integrated design, the retractable self-cleaning nozzles, or the gentle-close lid. It’s the difference between a $20 phone case and an OtterBox — both protect your phone, but the experience is different.
Installation: Easier Than You Think (Usually)
Installation was the most discussed topic across both TikTok comments and Costco reviews. The consensus: most people installed it in 15-30 minutes with no plumber needed.
One Costco reviewer described a straightforward 15-minute install with no leaks. Another reviewer — a self-described non-handy person — had it working in 15 minutes and was impressed by the water pressure. A reviewer who already had an older Brondell bidet said swapping to the CL150 took about 30 minutes and fit perfectly on their Toto Drake toilet.
However, installation isn’t always smooth. The most common complaints involved the mounting hardware. Multiple reviewers noted that the plastic mounting anchors were extremely tight and required tapping them in with a hammer or rubber mallet. One reviewer said the instructions fail to mention that you may need to break the plastic mounting piece in 2 to fit standard bolt holes. Another experienced leaks from the dial after 2 weeks and returned it.
The worst-case scenario came from a reviewer whose installation leaked overnight, with water running from the seat through the screw hole and damaging their kitchen ceiling below. This is rare but worth noting — if you install this, check for leaks immediately and recheck the next morning before walking away.
One TikTok commenter offered important advice: follow the instructions carefully and know which toilets are compatible, especially if you’re installing in a rental apartment where water damage could become an insurance issue.
Pro tip from the comments: Use plumber’s tape on all connections. Several successful installers mentioned this as the difference between a leak-free install and a problematic one.
The Cold Water Question
This was the #1 concern in both TikTok comments and reviews. The CL150 uses ambient (cold) water only — there is no heater. Multiple comments expressed concern about cold water, with the highest-liked comment on this topic (68 likes) saying to invest in a model with a heater.
Here’s the reality: the water comes from the same supply line as your toilet, which is room temperature. In warmer climates, it’s barely noticeable. In colder climates or during winter months, it can be bracing. One commenter described it as making you “pucker,” but added that you get used to it and eventually love it. Another commenter called it “ice water on your donut.”
If cold water is a dealbreaker for you, you have 2 options. The Brondell Ecoseat S102 on Amazon connects to your sink’s hot water supply for warm water washes without electricity. Or you can upgrade to a full electric bidet like the Brondell Swash CL1500 (also available at Costco when in stock) which has a built-in water heater, heated seat, and air dryer — but it requires an electrical outlet near your toilet and costs significantly more.
For most people, the cold water is a non-issue after the first week.
The “Why Not Just Buy a $20 One on Amazon?” Debate
This came up repeatedly in the TikTok comments. Multiple people said they bought bidets on Amazon for $15-25 and they work fine. They’re not wrong — basic bidet attachments do the job.
But the CL150 is a different product category. It replaces your entire toilet seat with an integrated bidet that has a modern, sleek look. The retractable self-cleaning nozzles stay hidden when not in use. The gentle-close lid prevents slamming. The quick-release button lets you remove the whole seat for deep cleaning. And the low-profile chrome dial is less obtrusive than the clunky hardware hanging off the side of most budget attachments.
One Costco reviewer specifically mentioned loving the low-profile controls compared to the “clunky hardware hanging off the side like most other models.” Another reviewer who already owned a more expensive bidet said they actually preferred the CL150 because it had better water pressure.
At $59.99 on sale, the CL150 sits in a sweet spot between the bare-bones Amazon attachments and the $300-500 electric models with heated seats and dryers.
Seat Size Warning
Multiple commenters and reviewers noted that the CL150’s toilet opening is slightly smaller than a standard elongated seat — roughly 1″ shorter in the back due to the bidet hardware. One reviewer was blunt about returning it because the seat hole was too small. Another described it as something you get used to but is worth knowing upfront.
This won’t be an issue for most people, but if you’re a larger person, test the fit before committing. One TikTok commenter with a self-described 400-lb frame said the seat supports his weight just fine and he loves it — so the weight capacity isn’t the issue, it’s the opening size.
Elongated Only — No Round Option
The CL150 at Costco fits elongated toilets only. TikTok commenters from apartments and older homes repeatedly asked about a round version. As of May 2026, Costco does not carry a round version of this model. If you have a round toilet, Brondell makes the Ecoseat 101 for round toilets, available on Amazon.
Not sure if your toilet is elongated or round? Measure from the front of the bowl to the center of the mounting bolts. Elongated is 18-19.5 inches. Round is 16-17.75 inches.
Handheld vs. Seat-Mounted: The Other Debate
Several commenters argued that a handheld bidet sprayer is cheaper, lasts longer, and gives you more control than a seat-mounted bidet. They’re not wrong — handheld models run $15-30, attach to your toilet’s water supply, and let you direct the spray manually.
The tradeoff is convenience. A seat-mounted bidet like the CL150 works hands-free — you turn the dial and let the nozzle do its thing. A handheld requires you to reach back and aim, which some people find uncomfortable or difficult.
It comes down to personal preference and budget. If you want the cheapest possible entry into the bidet world, a handheld sprayer is the way to go. If you want a clean, integrated look with hands-free operation, the CL150 is worth the premium.
Toilet Paper Savings: Real or Hype?
One commenter said their TP consumption dropped dramatically — a half Costco pack lasted over a year after installing a bidet. Another TikTok commenter said 1 roll of TP now lasts almost 2 months. A Costco reviewer titled their review “I’m buying less toilet paper.”
The math: a Costco Kirkland toilet paper pack runs about $20-25 for 30 rolls. If your household goes through a pack every month, that’s $240-300/year. Even cutting TP usage by 50% saves $120-150/year — meaning the CL150 pays for itself in under 6 months at the sale price.
One commenter who bought a bidet during what they called “the great toilet paper famine” said it was one of the best investments they’ve made. For context, toilet paper shortages happened during the pandemic, and bidet sales skyrocketed as a result.
What Real Owners Say (The Verdict)
Across 200+ TikTok comments and 20 Costco reviews, the overwhelming sentiment is positive. The most common phrase from owners: “life-changing.” The most-liked TikTok comment (70 likes) came from someone who said they’ve had the exact Brondell for about a year, their family loves it, and it supports their 400-lb frame.
The top comment overall (62 likes) said it’s time for “the American bidet revolution” and that cleaning with dry paper is unsanitary. Multiple international commenters (from Japan, South Asia, and Europe) expressed confusion about why Americans don’t already use bidets.
The negative feedback centered on 3 themes: cold water (solved by upgrading to a heated model), installation difficulties with the mounting hardware (solved by using plumber’s tape and a rubber mallet), and the slightly smaller seat opening (a matter of personal fit).
The Bottom Line
At $59.99 on sale through 5/31/26, the Brondell Swash CL150 is the best value non-electric bidet seat you can buy right now. It’s not the cheapest option — $20 Amazon attachments exist — and it’s not the most luxurious — electric models with heated water and dryers start around $300. But for a clean-looking, integrated bidet seat that installs in 30 minutes and works without electricity, it hits the sweet spot.
Buy it if: you want a bidet without needing an electrical outlet, you care about how it looks on your toilet, and you’re comfortable with ambient-temperature water.
Skip it if: cold water is an absolute dealbreaker (get an electric model instead), you have a round toilet (not compatible), or you just want the cheapest possible bidet (get a $20 attachment on Amazon).
