The Kohler PureWash E875 Is the More Feature-Complete Seat
If you’re shopping in this price range and want everything Kohler has to offer in a mid-tier seat, the E875 delivers it.
The E875 is part of the same PureWash family as the E880, sharing the same stainless steel self-cleaning wand, adjustable water temperature and pressure, quiet-close lid, and quick-release hinges for easy cleaning.
But the E875 adds two features the E880 simply doesn’t have: a motion-activated, hands-free lid that opens as you approach the toilet, and a built-in LED nightlight that illuminates the bowl.
These additions make the E875 genuinely more convenient — especially for nighttime bathroom trips.

2. Kohler PureWash E880 Elongated Bidet Seat
The E880 is Kohler’s most accessible upper-mid-tier bidet seat, and it offers an impressive set of features at a competitive price point.
Where the E880 distinguishes itself from the E875 is in its innovative three-sided rotating wand, which delivers three distinct spray modes: stream, mist, and air mist.
That’s a meaningful difference in how the wash actually feels and functions — the rotating wand gives you more variety in your cleansing experience than a standard front-and-rear setup.
Features
- Innovative three-sided rotating bidet wand with three spray modes: stream, mist, and air mist
- Stainless steel wand automatically cleaned before and after each use
- Front and rear warm water wash modes
- Heated seat with adjustable temperature
- Oscillating and pulsating spray options
- Handheld remote control with two programmable user presets
- Three-level adjustable nozzle position, water temperature, and pressure
- Quiet-Close lid and quick-release hinges
Pros
- The three-mode rotating wand is a genuinely unique feature not found on most bidet seats
- Available online with full retail support — easy to purchase and return
- Excellent stainless steel wand quality and UV cleaning
- Competitive pricing for the feature set
- Fits most standard elongated toilets easily
Cons
- No motion-activated lid — you’ll open it manually
- No nightlight — not ideal for nighttime bathroom visits
- No built-in deodorizer
- Air dryer not included at this tier
The E880 is the better choice if you want Kohler quality without the Costco membership requirement, and the rotating three-mode wand genuinely sets it apart from competitors at this price.

Head-to-Head: E875 vs E880 Compared
Spray Modes and Wand Performance
This is where the two seats actually diverge more than you might expect.
The E875 uses a straightforward front-and-rear wash setup with adjustable pressure and temperature — reliable, familiar, and easy to use right out of the box.
The E880 takes a different approach entirely with its three-sided rotating wand that delivers stream, mist, and air mist modes.
The mist mode is particularly popular with users who prefer a gentler, more enveloping spray rather than a direct stream.
If wash variety matters to you, the E880 wins this category.
Convenience Features
The E875 pulls ahead here with two additions that the E880 simply can’t match: the motion-activated lid and the LED nightlight.
Walking up to the toilet and having the lid open automatically feels genuinely luxurious — it’s the kind of touchless experience you associate with higher-end seats like those in our roundup of the best bidets for existing toilets.
The nightlight is practical too, especially if you share a bathroom and want to avoid waking a partner by flipping the lights on at 2am.
Winner: E875 — the hands-free lid and nightlight are meaningful quality-of-life upgrades.
Availability and Ease of Purchase
This is a big factor that often gets overlooked in comparisons.
The E875 is a Costco exclusive, which means you need a Costco membership to purchase it, and post-sale support, returns, and warranty claims run through Costco rather than through standard retailer channels.
The E880 is sold through major online retailers, making it easy to buy, track, and — if needed — return.
If you don’t have a Costco membership or prefer the flexibility of online purchasing, the E880 wins outright.
Build Quality and Cleaning
Both seats share the same core PureWash engineering: stainless steel wand, Quiet-Close lid, grip-tight bumpers, and quick-release hinges.
Stainless steel is an important detail here — most competing seats in this price range use plastic wands, which are more susceptible to mineral buildup and bacterial growth over time.
You can read more about why wand material matters in our guide to the best heated bidet toilet seats.
Winner: Tie — both seats share the same high-quality internal components.
Value for What You Pay
The E875 carries a slightly higher price at Costco (around $549) but includes the motion-activated lid and nightlight that justify the premium.
The E880 is typically priced lower and is available through multiple retailers, which keeps the price competitive.
If you have a Costco membership, the E875 offers more features per dollar spent.
If you don’t, the E880 is a genuinely excellent seat at its price point and the rotating wand gives you something the E875 doesn’t have.
Winner: Depends on your membership status — E875 wins on features-per-dollar if you shop at Costco; E880 wins on accessibility.
Verdict — Which One Should You Buy?
Both the Kohler E875 and E880 are excellent bidet seats from one of the most respected names in the bathroom fixture industry.
They share core engineering quality that puts them well ahead of most of their competitors, particularly in wand material and self-cleaning performance.
The decision really comes down to where you shop and which convenience features matter most to you.
Buy the Kohler PureWash E875 if: You’re a Costco member, you want a hands-free motion-activated lid, or you make nighttime bathroom trips and would genuinely use a nightlight.
Buy the Kohler PureWash E880 if: You prefer shopping online, you don’t have a Costco membership, or you’re specifically interested in the rotating three-mode wand experience (stream, mist, air mist) that you won’t find on the E875.
Either way, you’re getting a stainless steel wand, heated seat, remote control with programmable presets, and the engineering reliability that Kohler is known for — which puts both seats in a strong position compared to the broader bidet brand landscape.
FAQ
Is the Kohler E875 available on Amazon?
No — the Kohler PureWash E875 is a Costco-exclusive product (Model 30970-0) and is not sold on Amazon or most online retailers.
If you don’t have a Costco membership, the closest comparable seat available online is the Kohler PureWash E880, which shares the same core wand and seat technology while adding the unique three-mode rotating spray.
What is the main difference between the E875 and E880?
The E875 adds a motion-activated, hands-free lid and an LED nightlight that the E880 doesn’t include.
The E880, in turn, features a three-sided rotating wand with three spray modes (stream, mist, air mist), which gives it more wash variety than the E875’s standard front-and-rear setup.
Both seats use a stainless steel self-cleaning wand, heated seat, and handheld remote with two user presets.
Do either of these seats have a warm-air dryer?
Neither the E875 nor the E880 includes a warm-air dryer.
If an air dryer is a priority for you, look at the Kohler PureWash E820 (which adds a dryer and deodorizer) or the E930 (which adds app control and a slimmer profile).
You can explore the full breakdown of seats with dryers in our bidet toilet seat comparison chart.
Are these seats compatible with one-piece and two-piece toilets?
Yes — both the E875 and E880 are designed to fit most standard elongated one-piece and two-piece toilets.
Before purchasing, measure the distance from the seat post holes to the front of your toilet bowl: it should be between 18″ and 19.5″ for a proper fit.
