Brondell Swash LE99 Review: Warm Water, Stainless-Steel Nozzle, Dryer and Customizable Bidet Comfort

The Brondell Swash LE99-EW is an elongated electronic bidet toilet seat designed for users who want a more comfortable and customizable bathroom experience without replacing the entire toilet. It combines warm-water cleansing, a warm-air dryer, front and rear wash modes, adjustable nozzle position, multiple pressure and temperature settings, a remote control, and a built-in nightlight in one seat.

Its biggest appeal is breadth of control. The LE99 offers five nozzle positions, five water-temperature settings, five water-pressure levels, strong and soft wash modes, plus oscillating and pulsing spray options. That gives users considerably more flexibility than a basic bidet attachment, while still being simpler and less expensive than many full smart toilets.

The seat also uses a self-cleaning nozzle fully encased in stainless steel, an important durability and hygiene feature, and employs hybrid heating technology to provide an extended warm-water wash rather than relying entirely on a small reservoir.

For buyers considering a feature-rich bidet seat for an existing elongated toilet, the Swash LE99 deserves attention because it focuses on the functions that matter most in everyday use: cleaning performance, temperature comfort, adjustability, drying, and straightforward controls.

What Is the Brondell Swash LE99?

The Brondell Swash LE99 is an electric bidet toilet seat for compatible elongated toilets.

It replaces the existing toilet seat while leaving the toilet bowl, tank, and flushing system unchanged.

Once installed, the LE99 connects to the toilet's clean water supply and a nearby electrical outlet. Electricity powers the water heating system, warm-air dryer, controls, nightlight, and other electronic functions.

The seat measures approximately 20.8 inches long, 16 inches wide, and 5.7 inches high according to the supplied specifications.

Main Features at a Glance

The LE99 combines a fairly comprehensive feature set:

• Warm-water front and rear cleansing
• Strong wash mode
• Soft wash mode
• Oscillating spray
• Pulsing spray
• Five nozzle positions
• Five water-pressure settings
• Five water-temperature settings
• Stainless-steel-encased self-cleaning nozzle
• Warm-air dryer
• Lite-Touch remote control
• Nightlight
• Programmable settings
• Elongated-seat design

That puts it firmly in the premium electronic bidet-seat category rather than the simpler non-electric attachment segment.

Warm-Water Cleansing

The LE99 uses an advanced hybrid heating system intended to provide an extended warm-water wash.

Warm-water cleansing is one of the most meaningful differences between an electronic bidet seat and a mechanical attachment.

A cold-water bidet can work perfectly well from a hygiene perspective, but warm water is usually much more comfortable, particularly in winter or in air-conditioned bathrooms.

The hybrid design aims to provide warmth for longer wash cycles without the abrupt temperature drop that can occur with some basic reservoir-style seats.

What "Extended Warm Water" Means

The product does not claim truly unlimited warm water in the supplied text.

Instead, it describes an extended warm-water cycle.

That distinction matters.

Some bidet seats use a small heated reservoir, some use instant tankless heaters, and others combine the two approaches.

The LE99's hybrid system appears designed to balance warm-water duration with heating efficiency.

If unlimited warm water is an essential requirement, buyers should confirm the exact heating behavior in Brondell's current specifications.

Rear Wash

Rear wash is the standard cleansing function for everyday toilet use.

The nozzle directs an aerated stream toward the rear cleansing area.

Because pressure, nozzle position, and temperature can all be adjusted, users can make the wash gentler or stronger depending on personal preference.

For most owners, rear wash will likely be the most frequently used feature.

Front Wash

Front wash provides a more forward spray position for feminine cleansing.

Separate front and rear wash modes make the seat more versatile than single-position attachments.

The adjustable nozzle can further refine positioning, which can reduce the need for users to shift around significantly on the seat.

Five Nozzle Positions

The LE99 provides five nozzle-position settings.

This is particularly useful because body position and toilet geometry vary from one user to another.

A fixed nozzle can require users to reposition themselves.

Multiple positions allow the spray to be moved forward or backward until the stream reaches the preferred area.

In a shared bathroom, this level of adjustment can make the seat much easier for different people to use comfortably.

Five Water-Pressure Levels

The seat also offers five water-pressure settings.

That is a useful range.

Some users prefer a strong stream, while others may find high pressure uncomfortable.

First-time bidet users often benefit from starting at a lower level and increasing gradually.

The ability to fine-tune pressure is one of the LE99's strongest advantages over basic mechanical bidets.

Five Water-Temperature Settings

Water temperature is adjustable across five settings according to the supplied description.

This gives users meaningful control across seasons.

A lower setting may be more comfortable during summer, while a warmer wash may be appreciated during colder months.

Temperature adjustment also makes the seat easier to share among people with different comfort preferences.

Strong Wash Mode

The Strong Wash Mode increases spray power for users who want a more forceful rinse.

This can be useful when standard pressure settings feel insufficient.

However, stronger is not necessarily better for every user.

A comfortable wash should feel effective without causing irritation.

Users with sensitive skin should generally begin with gentler settings.

Soft Wash Mode

The Soft Wash Mode is intended for gentler cleansing.

This can be useful for users who find normal pressure too strong or simply prefer a lighter stream.

Having dedicated strong and soft modes is convenient because it reduces the amount of manual adjustment needed between different use cases.

Oscillating Wash

The oscillating function moves the spray over a larger area.

Instead of directing water at one fixed point, the nozzle moves back and forth.

This can improve coverage and help create a more thorough wash.

It is especially useful when paired with moderate pressure.

Pulsing Wash

The pulsing function changes water pressure rhythmically.

Some users may find this more comfortable than a completely steady stream.

It also adds another layer of customization without requiring the user to reposition on the seat.

Naturally Aerated Spray

The supplied description states that the front and rear washes are naturally aerated.

Aerating the water mixes air into the stream.

This can create a spray that feels fuller while remaining relatively gentle.

The practical benefit is improved comfort without relying solely on higher pressure.

Fully Stainless-Steel-Encased Nozzle

The self-cleaning nozzle is fully encased in stainless steel.

This is an important construction feature.

Some bidet seats use plastic nozzles or partially metal-covered designs. A fully stainless-steel exterior can provide improved resistance to corrosion and wear while remaining easy to clean.

The material does not eliminate maintenance, but it is a sensible choice for a component repeatedly exposed to water.

Self-Cleaning Nozzle

The nozzle rinses itself as part of the operating cycle.

That helps reduce residue between uses.

However, "self-cleaning" should not be interpreted as maintenance-free.

The nozzle and surrounding area should still be inspected periodically and cleaned according to Brondell's instructions.

Hard water may also leave mineral deposits over time.

Warm-Air Dryer

After washing, the LE99 provides a warm-air dryer.

This can reduce the amount of toilet paper needed after cleansing.

Some users may use the dryer almost exclusively, while others may prefer a small amount of paper to finish drying.

The benefit is flexibility rather than guaranteed paper-free use.

Why a Dryer Adds Value

A bidet solves the cleaning stage, but water still leaves moisture behind.

A built-in dryer completes more of the routine electronically.

That can make the overall experience feel significantly more integrated than a bidet attachment without drying.

Lite-Touch Remote Control

The LE99 includes Brondell's Lite-Touch remote.

A remote can be more comfortable than fixed side controls because it can be positioned where the user can see and reach it easily.

This is particularly valuable on a seat with many settings.

Instead of crowding controls onto a narrow side panel, the remote provides clearer access to wash type, nozzle position, pressure, temperature, and drying functions.

Programmable User Settings

The supplied description mentions programmable settings.

This can be useful in a shared household because users often prefer different pressure, temperature, and nozzle configurations.

Instead of manually adjusting everything each time, presets can simplify repeated use.

The exact number and scope of programmable profiles should be confirmed in the current manual if this is a major buying consideration.

Built-In Nightlight

The seat includes a nightlight.

This provides gentle illumination during nighttime bathroom visits without requiring bright overhead lighting.

It can be especially useful in ensuite bathrooms, children's bathrooms, or homes where older adults may use the toilet at night.

It is a small feature, but one many owners appreciate daily.

Designed for Elongated Toilets

The LE99 is intended for elongated toilets.

That means compatibility should be checked before purchase.

An elongated bidet seat will not fit a round-front toilet correctly.

The manufacturer's dimensional drawing is more reliable than judging bowl shape by appearance alone.

What to Measure Before Buying

Before purchasing, verify:

• Bowl length
• Seat-bolt spacing
• Clearance from mounting bolts to tank
• Bowl width
• Rear clearance for the bidet housing
• Location of the nearest electrical outlet

Electronic bidet seats are larger at the rear than conventional toilet seats, so tank clearance can matter.

Electrical Requirements

Because the LE99 heats water, runs a dryer, powers the remote receiver, and operates other electronic features, it requires electricity.

The exact voltage and current requirements are not included in the source text.

Check Brondell's current installation guide before purchase.

A properly grounded bathroom outlet with any required GFCI protection should be used according to local electrical code.

Avoid Permanent Extension-Cord Use

An extension cord should not be treated as a permanent substitute for a properly located outlet unless Brondell explicitly approves it.

Bathroom appliances operate in a wet environment, so electrical installation matters.

If there is no suitable receptacle near the toilet, an electrician may be needed.

Water Connection

The bidet seat connects to the toilet's clean cold-water supply.

A T-valve typically splits the supply so water can continue feeding the toilet tank while also supplying the bidet.

The seat then heats that incoming water internally.

No separate hot-water line is generally necessary.

DIY Installation

Electronic bidet seats are usually simpler to install than a full smart toilet.

A typical setup involves removing the old seat, attaching the mounting plate, adding the water-supply T-valve, connecting the bidet hose, sliding the new seat into place, and connecting power.

For a standard compatible toilet, this can often be handled as a DIY project.

However, older shutoff valves or unusual toilet hardware can complicate installation.

Leak-Test Every Connection

Once plumbing is connected, reopen the shutoff valve slowly.

Inspect the:

• T-valve
• Toilet supply hose
• Bidet hose
• Seat water inlet

All connections should remain completely dry.

If a connection leaks, turn off the water and check washers and thread alignment before tightening further.

Cleaning and Maintenance

Use mild, non-abrasive cleaners suitable for electronic bathroom fixtures.

Avoid spraying large amounts of water directly into the rear electronic housing.

A damp cloth is generally safer for exterior surfaces.

The nozzle should be inspected regularly even though it is self-cleaning.

Hard-Water Considerations

Mineral buildup can affect any bidet seat.

Hard water may eventually leave deposits around the nozzle openings or inside narrow water passages.

If spray performance changes over time, scaling may be a possible cause.

Follow Brondell's approved cleaning procedures rather than using aggressive acids or sharp tools.

Bidet Seat vs. Basic Bidet Attachment

A basic non-electric attachment is much cheaper and requires no electricity.

However, it generally lacks:

• Heated water
• Warm-air drying
• Nozzle-position adjustment
• Nightlight
• Remote control
• User presets
• Multiple spray modes

The LE99 adds significantly more comfort and customization.

The tradeoff is higher cost, electrical dependence, and more components that may eventually require service.

Bidet Seat vs. Full Smart Toilet

A full smart toilet replaces the entire fixture and may add automatic flushing, motorized lids, foot sensors, or integrated deodorization.

The LE99 keeps the existing toilet in place.

That can be a better option if the bowl already flushes well and fits the bathroom.

It also makes future replacement less complicated because only the seat needs to be changed.

Does the LE99 Improve Flushing?

No.

The bidet seat has no effect on the toilet's flushing performance.

If the existing toilet clogs frequently or has weak bowl rinse, installing the LE99 will not fix those issues.

It upgrades cleansing and comfort only.

Is It Good for Shared Bathrooms?

Yes.

The combination of adjustable nozzle position, water pressure, temperature, strong and soft wash modes, and programmable settings makes it well suited to multiple users.

Different household members can customize the experience without needing different hardware.

Is It Good for Cold Climates?

Yes, and this is where its heated functions become especially valuable.

Warm water, a warm-air dryer, and other comfort features make an electronic seat more appealing in winter than a cold-water mechanical attachment.

The supplied text does not mention a heated seat, so buyers should not assume that feature is included unless confirmed in current specifications.

Is It Good for Older Adults?

Potentially.

Remote operation, warm-water cleansing, and drying can reduce how much reaching and twisting is required compared with paper-only cleaning.

However, the LE99 should not be treated as a medical or accessibility device unless specifically certified as such.

Users with mobility concerns should evaluate seat height, control placement, and transfer needs individually.

Is It Useful for Postpartum or Sensitive Users?

The supplied product information does not make specific medical claims.

A soft wash mode and adjustable pressure may feel gentler for some users, but recovery from childbirth, surgery, or medical conditions should follow healthcare guidance.

A bidet seat is a hygiene appliance, not a medical treatment.

Environmental Considerations

A bidet seat may reduce toilet-paper consumption because water does more of the cleansing.

The warm-air dryer can further reduce paper use.

However, electronic bidets also consume electricity for heating and drying.

The overall environmental balance depends on usage habits, electricity source, water consumption, and how much paper use actually decreases.

Common Buying Mistakes

One mistake is purchasing the elongated version for a round toilet.

Another is forgetting to confirm a nearby electrical outlet.

Users may also assume "self-cleaning" means the nozzle never needs maintenance.

Another mistake is assuming extended warm water means unlimited warm water.

Finally, some buyers focus on the number of features without considering whether they will actually use the remote, presets, oscillation, or dryer.

Main Advantages

The LE99's strongest advantage is customization.

Five nozzle positions, five pressure levels, five water-temperature settings, strong and soft wash modes, oscillation, pulsation, front and rear cleansing, and programmable settings allow the seat to accommodate very different preferences.

The fully stainless-steel-encased nozzle is another strong feature.

The remote, nightlight, extended warm-water cycle, and dryer add useful everyday comfort.

Potential Drawbacks

The LE99 requires electricity and a compatible elongated toilet.

The supplied source does not clearly state that the seat itself is heated, so buyers should verify that if heated seating is important.

The warm-water system is described as extended rather than unlimited.

Electronic components also make the seat more complex than a basic mechanical attachment.

And like most bidet seats, it does not improve the underlying toilet's flush.

Who Should Consider the Brondell Swash LE99?

The LE99 is best suited to buyers who want a substantial bidet upgrade without replacing the entire toilet.

It may be especially appropriate for:

• Primary bathrooms
• Shared households
• Cold-climate users
• Buyers who want warm-water cleansing
• Users who value adjustable pressure
• People who want front and rear wash modes
• Buyers who want a warm-air dryer
