In recent years, bidet toilet seats have moved from niche luxury items into practical bathroom upgrades that combine hygiene, comfort, and smart design. With growing attention to water usage, sustainability, and personal wellness, choosing a high-quality bidet seat can make a real difference in your routine—not just for cleanliness but for overall experience. Whether you’re upgrading an existing toilet bowl or building a premium restroom setup, the right bidet seat brings rinsing, drying, deodorising and seat-heating features into one unit.
At the same time, installing and selecting the correct model requires attention to compatibility (elongated vs round bowl, power outlet availability, fitment), features (heated seat, warm-water spray, air dryer, deodoriser), and cost/value. In this post we’ll walk through five strong options ranging from mid-premium to true flagship, helping you decide which bidet seat offers the best balance for your bathroom.
Our Top Picks:
- TOTO Washlet S5
- Kohler PureWash E820
- Brondell Swash LE99
- Bio Bidet BB-550
TOTO Washlet S5
The best bidet we’ve used, the Toto Washlet S5, combines excellent features, aesthetics, customization, and energy-saving options like no other model.
The S5 has instant hot water, an oscillating or pulsating spray, complete control over water and seat temperature, a five-position nozzle, and two different eco modes (one of which learns your usage patterns and lowers seat heat during periods of little use).
It’s all controlled by a remote with a clean and simple interface on the front and the lesser-used settings on the back. This division of the controls is surprisingly rare on warm water bidets and means you don’t have to constantly flip the remote over in your hands while controlling the spray.
Reasons to buy
- Continuous instant warm water (no waiting for a reservoir to fill).
- Excellent hygiene features.
- Heated seat with several settings, warm-air dryer, night-light, memory profiles.
Reasons to avoid
- You’ll pay a premium compared to entry or mid-tier bidets.
- Requires a nearby GFCI electrical outlet and sufficient space around the toilet for the wiring.
Kohler PureWash E820
Kohler’s PureWash E820 offers many premium features at a somewhat lower price point than ultra-flagship seats, making it a very strong value. It is designed for elongated bowls and offers heated seat, adjustable spray, warm-air dryer, UV self-cleaning and a remote. WIRED describes the E820 as “several hundred bucks cheaper than Totos” while still offering many comparable features.
Reasons to buy
- Great value: many of the “premium” features (heated seat, warm water, adjustable spray, UV/Nozzle cleaning) without the highest-end pricing.
- Easy installation: users report it is well built and straightforward to set up.
- Remote control, adjustable water/nozzle settings, warm-air drying and deodorisation included.
Reasons to avoid
- Some users report minor quirks in pairing the remote and night-light feature.
- While feature-rich, it does not quite match the ultra-premium build quality or deep customization (user profiles, ultra-slim design) of the very top models.
Brondell Swash LE99
Brondell’s Swash LE99 is a strong contender if you’re seeking advanced features at a more moderate cost. It includes a warm-water wash, warm-air dryer, stainless-steel nozzle, wireless remote, night-light and user memory settings. Reviewers praise its good performance under budget. One YouTube reviewer called it “the best bidet I’ve tested for under $300”.
Reasons to buy
- Strong feature set at a more accessible price: warm water, warm-air dryer, good build quality.
- Easy to install and good usability
- Night-light and memory settings add comfort and convenience beyond basic models.
Reasons to avoid
- Does not include a deodorizer in some versions.
- As with many mid-tier units, while feature-rich, the long-term durability or premium finish may lag top-tier brands.
Bio Bidet BB-550
The Bio Bidet BB-550 is a solid budget-friendly premium option. It offers unlimited warm water, heated seat, warm-air dryer, dual nozzles for front/rear wash, and a low-profile design (3.3″ tall at rear) which is great for fitting under tighter seat-lid spaces. Reviewers are positive about the build and comfort though some mention cord length or noise issues.
Reasons to buy
- Excellent value: many premium features (heated seat, unlimited warm water, dryer) at more affordable price compared to “luxury” models.
- Low-profile design: at only 3.3″ tall at rear, easier to install in tight spaces.
- Easily installation: many users found it straightforward to install with minimal fuss.
Reasons to avoid
- Some limitations: cord length may be short; some noise/beeping and build quality may not match the very top brands.
- Premium finish and advanced wand/air-flow rates may not be as refined as flagship models.
TOTO S7A (Premium Bidet)
The TOTO S7A is the flagship bidet seat from TOTO, marketed as “the best bidet seat money can buy” for those who want no compromises. It includes motorised lid/seat open-close, ultra-slim design (4.1″ rear profile), five spray settings, heated seat, instant water heating, and premium finish. Reviewers note the premium feel, though also point out that form-factor and cost are elevated.
Specifications
- Ultra-premium features: motorized lid/seat movement, ultra-slim build, top-tier hygiene and comfort components.
- Excellent user experience: reviewers say it is “a big hit” in households and leads the industry in design/comfort.
- Investment in long-term comfort and value: if you spend time installing once and keeping for many years, this is “buy it once” quality.
Reasons to avoid
- High cost: as expected for a flagship, budget-conscious buyers may find it overkill.
- Requires proper installation + sufficient space/power/outlet; also some cleaning complexity: reviewers mention “nooks and crannies that can be difficult to reach with the washlet installed”.
