Bidet vs Shower Toilet: What Is the Difference and Which Is Better?

A bidet and a shower toilet both use water for personal cleansing after using the toilet, but they work in very different ways. A traditional bidet is a separate bathroom fixture, while a shower toilet combines a WC and water-cleaning function in one unit.

For many European bathrooms, that difference is important. A conventional bidet requires additional floor or wall space and requires the user to move from the toilet to the bidet. A shower toilet allows you to remain seated while an integrated nozzle provides the cleansing water.

Modern shower toilets can also include features such as adjustable water temperature and pressure, heated seats, warm-air drying, automatic deodorisation, user profiles, night lights and automatic lid functions.

So which should you choose?

The answer depends on your bathroom, available space, budget, installation possibilities and the level of comfort you want.

What is a bidet?

A bidet is a separate sanitary fixture designed for washing the intimate area with water after using the toilet.

Traditional bidets are particularly common in countries such as Italy, Portugal, Spain and parts of Southern Europe.

They normally look similar to a low toilet or washbasin and are installed next to the WC. Water is controlled through a tap or mixer, allowing the user to adjust the temperature and flow.

The usual process is:

1. Use the toilet.

2. Move from the toilet to the bidet.

3. Wash with water.

4. Dry using toilet paper or a towel.

A bidet therefore provides effective water cleansing but requires enough bathroom space for two separate sanitary fixtures.

What is a shower toilet?

A shower toilet combines the functions of a toilet and a bidet in one appliance.

After using the toilet, an integrated washing nozzle extends from beneath the seat or ceramic unit and cleans the intimate area with a controlled stream of water.

Most modern electronic shower toilets allow the user to adjust settings such as:

• water pressure

• water temperature

• nozzle position

• spray pattern

• seat temperature

Depending on the model, additional functions can include:

• warm-air drying

• automatic deodorisation

• heated toilet seat

• oscillating or pulsating spray

• separate front wash

• adjustable nozzle position

• automatic nozzle cleaning

• automatic lid opening

• automatic flushing

• night or orientation lighting

• personalised user profiles

• remote control or smartphone operation

This type of toilet is also known by several other names.

You may see manufacturers, retailers and consumers use terms including shower toilet, bidet toilet, Japanese toilet, smart toilet, wash-and-dry toilet, bidet WC or electronic bidet toilet.

The terminology varies by country and manufacturer, but all generally describe toilets that incorporate a water-cleaning function.

Is a shower toilet the same as a Japanese toilet?

In normal consumer language, the terms often overlap.

A Japanese toilet usually describes an advanced toilet with electronic washing and comfort features inspired by toilets that became particularly popular in Japan.

A shower toilet is the term more commonly used by European sanitary manufacturers.

A modern Japanese-style toilet may include washing, drying, seat heating, deodorisation and automatic functions, while a simpler shower toilet may concentrate primarily on water cleansing.

The underlying idea is the same: personal cleansing with water without leaving the toilet.

Is a shower toilet the same as a bidet toilet seat?

Not exactly.

There are two main ways to add bidet functionality to a toilet.

Complete shower toilet

A complete shower toilet combines the ceramic WC and electronic washing system as one coordinated product.

Examples include models from manufacturers such as:

• TOTO

• Geberit

• GROHE

• VitrA

• Roca

• Duravit

• LAUFEN

Complete systems generally offer the most integrated appearance and may provide more advanced functions.

Electronic bidet seat

An electronic bidet seat replaces the normal toilet seat and adds a washing nozzle and electronic controls to an existing compatible toilet.

This can be an attractive option when the existing ceramic toilet does not need replacing.

You may also hear this type of product described as a bidet seat, shower toilet seat, electronic bidet seat or washlet-style toilet seat.

The term WASHLET itself is a trademark used by TOTO for its electronic toilet seat and integrated washing products.

The important consideration when buying a retrofit seat is compatibility. Toilet ceramics vary considerably in length, width, fixing-hole position and shape.

A bidet seat therefore cannot automatically be fitted to every toilet.

What is the biggest difference between a bidet and a shower toilet?

The biggest difference is integration.

With a traditional bidet, washing takes place on a separate sanitary fixture.

With a shower toilet, washing takes place directly on the toilet.

That changes the entire user experience.

Instead of:

toilet → move to bidet → wash → dry

a shower toilet allows:

toilet → wash → dry

without standing up.

For many buyers, this convenience is the main reason for choosing a shower toilet.

Which takes up less bathroom space?

A shower toilet normally requires considerably less bathroom space than installing both a toilet and a traditional bidet.

A conventional bidet needs its own:

• sanitary fixture

• water connections

• waste connection

• installation space

• clearance around the fixture

A shower toilet combines the WC and bidet functions in approximately the space occupied by a conventional toilet.

This can make shower toilets particularly attractive for:

• smaller bathrooms

• guest bathrooms

• apartments

• bathroom renovations

• accessible bathrooms

• modern minimalist bathrooms

If you are designing a new bathroom and would like water cleansing but do not want two separate ceramic fixtures, a shower toilet can therefore be the more space-efficient solution.

Does a shower toilet need electricity?

Most modern electronic shower toilets require an electrical connection.

Electricity powers functions such as the water heater, electronic nozzle, seat heating, dryer, deodorisation system and remote-control receiver.

If you are building or renovating a bathroom, it is therefore advisable to plan both the water connection and electrical supply before the WC is installed.

The exact electrical requirements depend on the manufacturer and model and should always follow the manufacturer's installation instructions and applicable local electrical regulations.

There are also simpler non-electronic washing systems available, but these normally offer fewer functions.

Does a traditional bidet need electricity?

Usually not.

A conventional ceramic bidet typically uses normal hot and cold water connections connected to a mixer tap.

This simplicity is one of its advantages.

However, it also means that features normally associated with electronic shower toilets—such as automatic washing programs, a heated seat or warm-air dryer—are not normally available.

Is a shower toilet more hygienic than toilet paper?

A shower toilet uses water rather than relying entirely on dry toilet paper for personal cleansing.

For many users, washing with water provides a more comfortable and thorough feeling of cleanliness.

Modern shower toilets are also designed so that the washing nozzle remains protected when not in use. Depending on the model, the nozzle may be automatically rinsed before and/or after washing.

Some premium models include additional nozzle-cleaning technologies.

The shower toilet itself still needs regular cleaning and maintenance, just like a conventional WC.

For best results, follow the manufacturer's recommendations regarding:

• toilet cleaning

• nozzle cleaning

• descaling

• filter replacement

• approved cleaning products

Does a shower toilet replace toilet paper completely?

It can significantly reduce the amount of toilet paper required, particularly if the shower toilet includes a warm-air dryer.

Whether toilet paper can be eliminated completely depends on the model and the user's preference.

With a basic shower toilet or electronic bidet seat without a dryer, some paper may still be used for drying.

With more advanced wash-and-dry toilets, the integrated dryer can reduce the need for paper further.

What are the advantages of a traditional bidet?

A traditional bidet still has several advantages.

It is mechanically simple, usually requires no electricity and can provide both warm and cold water through a normal mixer.

It may be a good choice when:

• there is plenty of bathroom space

• the bathroom already has a bidet installed

• electronic functions are not wanted

• simplicity is a priority

• the traditional bathroom layout is preferred

In some countries, a WC and separate bidet also remain a familiar and culturally preferred arrangement.

What are the advantages of a shower toilet?

The main advantage of a shower toilet is that it combines personal washing and toilet functions in one place.

1. It saves space

There is no need for a separate bidet beside the toilet.

2. You remain seated

Washing takes place immediately after using the toilet without transferring to another fixture.

3. Washing can be personalised

Many models allow adjustment of water temperature, spray strength and nozzle position.

4. Additional comfort functions are available

Depending on the product, these can include seat heating, drying, deodorisation, night lighting and automatic functions.

5. It can make the bathroom look less cluttered

Modern wall-hung shower toilets can look very similar to premium conventional toilets because much of the technology is concealed within the ceramic or seat.

6. It may be easier for people with limited mobility

Reducing the need to move between the toilet and a separate bidet can make personal washing easier for some elderly users or people with restricted movement.

Individual accessibility requirements vary, so bathroom design should always be considered around the needs of the person using it.

Are there disadvantages to shower toilets?

Yes. A shower toilet is not automatically the right solution for every bathroom.

Important considerations include:

Higher initial cost

Electronic shower toilets generally cost more than basic conventional toilets.

Prices vary substantially depending on the brand and functions.

Electrical installation

Most models require a suitable electrical supply near the WC.

More technology

A shower toilet contains electronic and mechanical components that a conventional toilet does not.

Choosing an established manufacturer with available spare parts and service support is therefore important.

Maintenance

Depending on local water hardness and the model, periodic descaling or filter maintenance may be required.

Compatibility during retrofitting

Installing a complete shower toilet onto an existing concealed cistern or frame can require compatibility checks.

An electronic bidet seat also needs to fit the existing WC ceramic correctly.

Can you retrofit a shower toilet without renovating the whole bathroom?

Yes, in many cases.

There are two common approaches.

Option 1: Install an electronic bidet seat

If the existing toilet ceramic is compatible, the conventional seat can sometimes be replaced with an electronic bidet seat.

You will normally need:

• a compatible toilet bowl

• water connection

• electrical connection

• sufficient space around the toilet

This is usually the least disruptive way of adding electronic washing functionality.

Option 2: Replace the existing toilet with a complete shower toilet

The existing ceramic WC can sometimes be replaced while keeping the concealed cistern or installation frame.

However, compatibility must be checked carefully.

Important points can include:

• fixing dimensions

• waste connection

• flush system

• water supply

• electrical supply

• installation frame

• required connection set

• automatic-flush compatibility

When replacing a wall-hung toilet, do not assume that every shower toilet will work with every concealed frame simply because the fixing spacing appears similar.

Check the manufacturer's installation requirements before ordering.

What should you check before buying a shower toilet?

Before choosing a model, answer these questions:

1. Do you want a complete toilet or only a bidet seat?

A complete toilet gives the most integrated result. A bidet seat can be easier for retrofitting.

2. Is electricity already available near the WC?

If not, electrical work may be required.

3. Is there a suitable water connection?

The shower toilet needs a clean water supply for its washing function.

4. Is your existing frame or cistern compatible?

This is especially important with wall-hung toilets.

5. Which functions will you actually use?

Consider whether you need:

• seat heating

• dryer

• deodorisation

• automatic lid

• automatic flushing

• user profiles

• remote control

• night light

Buying the model with the most functions is not always necessary.

6. Is manufacturer service available in your country?

A shower toilet is a long-term bathroom appliance. Spare-part availability and technical support can therefore be as important as the initial specification.

Bidet or shower toilet for elderly users?

Both provide water cleansing, but a shower toilet can offer an important practical advantage: the user does not have to move from the WC to another fixture.

Features such as remote controls, automatic flushing, automatic lids and warm-air drying can also reduce the number of physical movements required.

For bathrooms being designed specifically around reduced mobility, the overall installation should also consider toilet height, support rails, transfer space, floor layout and accessibility.

Bidet or shower toilet for a small bathroom?

For most small bathrooms, a shower toilet is easier to accommodate because it combines two functions in one sanitary fixture.

A separate toilet and bidet require significantly more wall and floor space.

An electronic bidet seat can be particularly useful where replacing the whole toilet is unnecessary or impractical.

Which is easier to clean?

Both require routine cleaning.

Traditional bidets are relatively simple sanitary ceramics, although they introduce another fixture, tap and surrounding floor area that must be cleaned.

A shower toilet eliminates the separate bidet but contains a washing nozzle and electronic components that need appropriate care.

Many modern shower toilets use:

• rimless ceramic designs

• concealed nozzle positions

• removable seats or lids

• automatic nozzle rinsing

• easy-clean ceramic surfaces

Always use cleaning products approved by the manufacturer, particularly around electronic components and specialised ceramic coatings.

How long does a shower toilet last?

A quality shower toilet should be considered a bathroom appliance rather than a disposable electronic product.

Its actual lifespan depends on factors including:

• product quality

• frequency of use

• water hardness

• maintenance

• correct installation

• availability of spare parts

For this reason, manufacturer support should be considered when comparing products.

Before purchasing, it is useful to ask whether replacement parts such as the remote control, seat, lid, nozzle components, filters or electronic assemblies will remain available.

Is a shower toilet worth it?

For someone who wants water cleansing but does not want a separate bidet, a shower toilet can be an excellent solution.

It is particularly attractive when you value:

• personal washing with water

• space efficiency

• comfort

• adjustable washing

• heated seating

• drying

• modern bathroom design

A traditional bidet remains a sensible choice when simplicity, no electrical requirement and the familiar two-fixture bathroom arrangement are more important.

The right choice therefore depends less on which technology is universally "better" and more on how you intend to use the bathroom.

Bidet vs shower toilet: which should you choose?

Choose a traditional bidet if you have plenty of bathroom space, prefer a simple non-electronic solution and are comfortable moving between two fixtures.

Choose a shower toilet if you want washing integrated directly into the WC, want to save bathroom space or value functions such as adjustable washing, seat heating or drying.

Choose an electronic bidet seat if you want many shower-toilet functions while retaining a compatible existing toilet ceramic.

For new bathrooms, it is worth considering a shower toilet at the planning stage even if you are not certain which model you will eventually purchase. Providing suitable water and electrical connections during construction can make a future installation considerably easier.

Frequently asked questions

What is the difference between a bidet and a shower toilet?

A bidet is normally a separate sanitary fixture installed beside the toilet. A shower toilet combines the toilet and water-cleansing functions in one unit, allowing the user to wash without leaving the toilet.

Does a shower toilet wash you automatically?

The user normally activates the washing function using a remote control, side control panel or button. Some premium models can remember individual washing preferences.

Do shower toilets use warm water?

Most electronic shower toilets can heat the cleansing water and allow the temperature to be adjusted.

Do shower toilets need hot-water plumbing?

Most electronic models heat the cleansing water internally and therefore normally require a cold-water supply rather than a separate domestic hot-water connection. Installation requirements differ by model.

Can I install a shower toilet on an existing concealed cistern?

Often yes, but compatibility must be checked. The cistern, installation frame, flush mechanism, water connection and shower-toilet model all need to be considered.

Can I add a bidet function to my existing toilet?

Possibly. A compatible electronic bidet seat can add washing functions without replacing the complete WC. The toilet dimensions and fixing points must be checked first.

Is a shower toilet the same as a smart toilet?

The terms overlap, but not every shower toilet is necessarily a highly automated smart toilet. A shower toilet primarily describes a WC with an integrated water-cleansing function. Smart toilets may add automatic flushing, sensors, app control and other electronic functions.

Is a Japanese toilet the same as a shower toilet?

The terms are often used for similar products. "Japanese toilet" is a popular consumer term, while "shower toilet" is widely used by European sanitary manufacturers.

What is a wash-and-dry toilet?

A wash-and-dry toilet is a shower toilet that combines water cleansing with an integrated warm-air dryer.

Do you still need toilet paper with a shower toilet?

Many people use less toilet paper. Models with a warm-air dryer can reduce the need further, although this depends on personal preference.

Need help choosing a shower toilet?

Choosing a shower toilet involves more than comparing features. The toilet also needs to suit your bathroom, installation system and available connections.

Before ordering, check:

• toilet dimensions

• wall-hung or floor-standing installation

• concealed cistern or frame compatibility

• water connection

• electrical connection

• required installation accessories

• availability of spare parts and servicing

Tooaleta specialises in shower toilets, electronic bidet seats and Japanese-style toilets from leading European and Japanese sanitary manufacturers.

If you are unsure which model will fit an existing bathroom, provide the make and model of your current WC or installation frame together with photographs and dimensions. Compatibility can then be checked before you purchase.
