Elevate Your Bathroom Experience

The Complete Guide to Electric Bidet Seats

Standard UK Supply: 220-240V | 50-60Hz

Discover a new standard of personal hygiene, comfort and sophistication. An electric bidet seat transforms your daily routine, offering exceptional cleanliness and a touch of everyday luxury. Whether retrofitting an existing toilet or incorporating into a refurbishment project, our seats are designed for you.

DIY Friendly: Manufacturers offer bidet seats as “Do It Yourself” products, meaning installation is simplified and does not typically require an authorised plumber. If hard-wiring or cable adjustment is required, this should be carried out safely and in accordance with the manufacturer’s instructions and UK bathroom electrical requirements.

Note: If you would prefer an expert installation, TOOaleta is currently expanding a database of installers in your region.

Essential Connections

To successfully install an electric bidet seat, you require two primary access points:

  • Power: suitable electrical connection
  • Water: cold water supply

Pre-Purchase Fitment Check

At TOOaleta, we have made this an easy two-step process to help ensure you buy the right seat for your ceramic. Please verify these steps before purchasing.

Step One: Determine Your Toilet Type

1. Wall-Hung Toilets

Example of a wall-hung toilet connected to a concealed cistern

These toilets are mounted onto a concealed drywall frame or cistern and do not touch the floor.

Fitment Rule: Virtually all wall-hung toilets require an elongated bidet seat.

2. Close-Coupled / Floor Standing Toilets

Example of a close-coupled or floor standing toilet

This type has the cistern tank bolted directly onto the bowl, which stands on the floor.

Fitment Rule: Most close-coupled toilets accept round/short versions, but many modern ones are elongated. You must measure in Step Two to be sure.

Step Two: Measure Your Toilet

Measure carefully before ordering. The most important checks are the distance between the fixing holes, the distance from the fixing holes to the front of the bowl, and the available space between the fixing holes and the cistern or wall.

Unsure about fitment?

Electrical Requirements

Professional positioning: Most bidet seat models feature the power cord exiting from the left-hand side when facing the toilet.

For the cleanest aesthetic, we recommend your electrician installs the socket low and to the side. This allows you to hide cables behind the ceramic bowl for a high-end, “cordless” appearance.

Water Supply Connection Options

Option A: Close-Coupled Toilets

Using the supplied T-connector, the bidet water hose can be connected to the fill valve. In many WCs this valve is inside the cistern, but sometimes it is external.

Internal Cistern Valve Cold-water connection for an internal cistern valve
External Isolation Valve Cold-water connection for an external cistern valve

Option B: Adjacent Washbasin

If your toilet is adjacent to a vanity unit or washbasin, the T-connector can be fitted beneath the washbasin. This can be a discreet route, as the hose can often be fed neatly through the cabinet side directly to the seat.

Option C: Concealed Cisterns / Wall-Hung Toilets

For modern wall-hung toilets, the water supply is typically accessed behind the flush plate using a Y-connector on the inlet valve. If your wall is already tiled without access, please contact us for guidance before starting any work.

Premium frames, such as Geberit Duofix, may have pre-marked shower toilet connection points behind the flush plate.

Frequently Asked Questions

Can I install an electric bidet seat on my existing toilet?

In many cases, yes. The toilet shape, fixing-hole position, bowl length, water access and electrical connection must be suitable for the selected bidet seat.

Do I need hot water for an electric bidet seat?

Most electric bidet seats connect to the cold-water supply and heat the water internally. The exact heating system depends on the model.

Which side does the power cord usually exit from?

Most models have the power cord exiting from the left-hand side when facing the toilet, although the exact position can vary by model.

Can the water connection come from the washbasin?

Yes, in some bathrooms the cold-water connection can be taken from the angle valve beneath a nearby washbasin, provided the route is suitable and professionally installed.

Can a bidet seat be fitted to a wall-hung toilet?

Often, yes, but wall-hung toilets usually require an elongated seat and the water supply may need to be accessed through the concealed cistern or prepared connection point.

Should I contact TOOaleta before ordering?

If you are unsure about fitment, toilet shape, electrical placement or water connection options, it is best to contact us before ordering.
