Our Picks: Best Aftermarket Bidet Toilet Seat reviews
1. TOTO WASHLET A2: A Straightforward Heated Seat with Warm Water
The TOTO WASHLET A2 focuses on the core features many people want in an electronic bidet seat: front and rear cleansing, warm water, and a heated seat. Its oscillating wash option and adjustable water temperature and pressure give you room to tailor the experience.
The self-cleaning wand rinses itself before and after use, while the CLEAN RESIN material is designed to help repel materials. A side panel puts the controls on the seat itself, so you do not need to keep track of a separate remote. The SoftClose seat and lid are designed to close gently.
This elongated model is a sensible fit for shoppers who want a familiar TOTO design and straightforward controls. Compared with the more elaborate S2, the A2 has a shorter feature list: its product details do not list a warm-air dryer, deodorizer, or night light. It is also worth checking your toilet’s shape and available outlet before ordering.
Pros:
- Adjustable warm-water front and rear wash with an oscillating option
- Heated seat with coverage across the seat surface
- Self-cleaning wand and CLEAN RESIN surface
- Side-panel controls and SoftClose seat and lid
Cons:
- No warm-air dryer or deodorizer is listed in the supplied product details
- Side-panel controls may be less convenient than a wireless remote for some bathroom layouts
Verdict: Choose the WASHLET A2 if you want warm-water cleansing and a heated seat in a relatively simple TOTO package.
2. ALPHA BIDET JX2: A Slim Seat with a Wireless Remote
The ALPHA BIDET JX2 is an elongated electronic bidet seat with on-demand tankless water heating. The product description says it supplies endless warm water, which can be useful if you prefer not to rely on a limited reservoir of heated water.
Its low-profile design and whisper-quiet operation are aimed at a less obtrusive setup. A wireless remote has shortcut buttons, and an ambient-light-sensing LED nightlight can help illuminate the bathroom in the dark. The aluminum wash nozzle is self-cleaning.
The JX2 may suit you if you want a remote-controlled seat with a nightlight and a slim look. Its supplied feature list is more focused than the TOTO S2 or Bio Bidet BB2000: it does not list a warm-air dryer, deodorizer, or heated seat. Confirm that your toilet is elongated and review the installation details for your bathroom before purchase.
Pros:
- Tankless on-demand warm-water heating
- Wireless remote with shortcut buttons
- Low-profile design and quiet operation
- Self-cleaning aluminum nozzle and sensor-activated nightlight
Cons:
- Heated seat and warm-air dryer are not listed in the supplied product details
- Designed for elongated toilets, so bowl shape needs to be checked
Verdict: The JX2 is a good match if a slim profile, quiet operation, and remote control matter more to you than a dryer or heated seat.
3. TOTO WASHLET S2: More Comfort Features, Including a Warm-Air Dryer
The TOTO WASHLET S2 builds on the basic warm-water wash with a broader set of comfort and hygiene features. It offers front and rear cleansing, oscillating and pulsating options, adjustable water settings, a heated seat, and a warm-air dryer. A built-in deodorizer and night light add convenience beyond the wash itself.
For bowl and wand care, PREMIST sprays the bowl before use to help prevent waste from sticking. The wand cleans itself with EWATER inside and out, and the CLEAN RESIN material is designed to help repel materials. Controls are located on a side panel, making the seat’s settings accessible without a separate remote.
The S2 is the most feature-rich TOTO option in this group. It may suit households that value drying and deodorizing features as well as adjustable cleansing. Its extra functions may be more than you need if you only want a warm-water wash and heated seat; in that case, the A2 has a more focused feature set. Check toilet compatibility and electrical setup, including whether your toilet has the concealed connection needed for a WASHLET+ installation.
Pros:
- Instant and continuous warm water with adjustable pressure and temperature
- Warm-air dryer, deodorizer, and built-in night light
- PREMIST bowl mist and self-cleaning EWATER+ wand
- Oscillating and pulsating wash options
Cons:
- Its many features may be unnecessary if you want a basic bidet seat
- Compatibility checks are important, especially for WASHLET+ concealed connections
Verdict: Pick the WASHLET S2 if you want a TOTO seat with a dryer and several added comfort and hygiene functions.
4. Edencho Electric Heated Bidet Seat: Adjustable Wash and Drying
This Edencho electric seat combines adjustable warm-water cleansing with seat heating and a warm-air dryer. Its listed wash options include front and rear wash, one-touch auto cleaning, and an oscillating wash. The remote also adjusts nozzle position and includes a memory function.
Other practical touches include a soft-close seat and lid, a switchable beep, and a remote-controlled nightlight. The product specifies warm-water adjustment from 92 to 102°F. These settings offer flexibility, but the supplied details do not name a particular toilet shape, so check the seat’s fit measurements and compatibility information before ordering.
Installation planning is especially important for this model. It must connect to a clean water source and a grounded three-prong 100–120V outlet, and its power cord is 40 inches long. Compare that cord length with your outlet location. The feature list is appealing, but shoppers who prefer a well-established brand name or a specific fit standard may want to compare the other options carefully.
Pros:
- Front and rear wash with adjustable warm water
- Heated seat, warm-air dryer, and self-cleaning nozzle
- Remote with nozzle adjustment, oscillating wash, and memory function
- Nightlight, soft-close seat and lid, and switchable beep
Cons:
- Requires a grounded three-prong 100–120V outlet and a clean water connection
- Confirm toilet fit and outlet placement; the supplied description does not specify a bowl shape
Verdict: Consider the Edencho if you want adjustable wash and drying features and can confirm that your toilet and electrical setup are compatible.
5. Bio Bidet BB2000 Bliss: A Full-Featured Seat for Elongated Toilets
The Bio Bidet BB2000 Bliss bundles warm-water cleansing with a heated seat, warm-air dryer, night light, and built-in deodorizer. A wireless remote lets you adjust wash temperature, water pressure, and nozzle position, making this a flexible option for households where people prefer different settings.
The product details list stainless steel nozzles and an easy-to-clean plastic seat and lid. It is designed for standard elongated toilets and requires an electrical outlet to use its full set of features. The manufacturer describes the installation as a do-it-yourself project and notes that US-based customer support is available.
Compared with the TOTO A2, the BB2000 has more listed comfort features, including a dryer and deodorizer. It is closer in feature range to the TOTO S2, though the control style differs: the BB2000 uses a wireless remote, while the S2 has a side panel. Its elongated fit is a key limitation, so measure your toilet before deciding.
Pros:
- Warm water, heated seat, and warm-air dryer
- Wireless remote adjusts wash temperature, pressure, and position
- Night light and built-in deodorizer
- Stainless steel nozzles and listed DIY installation support
Cons:
- Fits standard elongated toilets, so it may not suit other bowl shapes
- Requires an electrical outlet for its full feature set
Verdict: Choose the BB2000 if you have an elongated toilet and want a remote-controlled seat with a dryer, deodorizer, and heated seat.
How to Choose an Aftermarket Bidet Toilet Seat
Confirm the toilet shape and seat fit
Start by checking whether your toilet is elongated or round and compare its measurements with the seat’s fit information. Some options here specify elongated toilets, while others say they fit most standard toilets or do not identify a bowl shape in the supplied details. Do not rely on appearance alone; confirm the exact fit before ordering.
Check your outlet and water connection
Electronic bidet seats need an appropriate power source for their powered features, and installation details can differ by model. Check the manufacturer’s instructions for the required outlet and water connection. For the Edencho, the product details specify a grounded three-prong 100–120V outlet, a clean water source, and a 40-inch power cord. Make sure the outlet is close enough and suitable for the installation.
Choose the wash settings you will use
Warm-water seats can vary in how they heat water and which wash options they offer. The A2 and S2 list adjustable temperature and pressure, while the JX2 specifies tankless on-demand heating. If you want more control over the wash, look for options such as oscillating or pulsating cleansing and adjustable nozzle position.
Decide whether a heated seat or dryer matters
A heated seat can add comfort, while a warm-air dryer may reduce how much toilet paper you use. Not every model in this group lists both features. The S2, Edencho, and BB2000 include a dryer in their supplied descriptions, while the A2 focuses on cleansing and seat warmth. Match the feature list to your routine rather than choosing a more complex seat by default.
Compare the controls and nighttime features
A side panel keeps settings attached to the seat, while a wireless remote can be easier to reach from different positions. The A2 and S2 use side-panel controls; the JX2, Edencho, and BB2000 list remotes. If you use the bathroom at night, look for a built-in nightlight and check how it is controlled.
Consider cleaning and maintenance features
Look at how the wand and seat surfaces are designed to be cleaned. Several choices list self-cleaning nozzles or wands, and the TOTO models also describe materials or functions aimed at helping keep the seat or bowl cleaner. These features support routine care, but they do not remove the need to follow the product’s cleaning instructions.
Keep the installation in mind
Before buying, review the installation instructions and confirm that your toilet has the needed space, water connection, and power access. Some products describe DIY installation, but the time and difficulty can depend on your bathroom setup. Check the included parts and support options, and consider professional help if your connections or outlet do not match the requirements.
