Which bidet toilet seat is best?

The first time you try a bidet toilet seat, you’d be excused for thinking you have stumbled on to the set of a sci-fi movie rather than entered a washroom. They resemble a regular toilet seat but are loaded with innovative features, making washing up easier and more comfortable.

The primary function of a bidet toilet seat is for washing yourself and comes with all manner of hi-tech gadgetry which can enhance the experience. A high-quality option is the TOTO Washlet C5 with front and rear sprayers, adjustable water pressure, temperature settings and an air deodorizer.

What to know before you buy a bidet toilet seat


The number and type of features on a bidet toilet seat range significantly from model to model. However, all bidets include a hygienic nozzle that sprays water from beneath for cleaning your body after use. Some models have a heater, which gently warms the water first, making it more comfortable to use.

High-end bidet toilet seats may also incorporate additional features such as hot air dryers, air deodorizers, heated seats and even LED lights and personalized memory settings. For a comprehensive list of the various features available, visit the Best Bidet Seat review at BestReviews.


Installing a new toilet seat is relatively easy, as most are held on with just two to four screws. Depending on the bidet seat’s functions, it will also need a water supply and possibly an electrical supply, so make sure you have these set up prior to installing your bidet. It is essential to choose a seat that will fit your existing toilet as most models are available in two sizes: regular and elongated.

Electric vs. non-electric

Some bidet toilet seats don’t need a power supply and rely on water pressure alone. However, for those that incorporate a water heater, an air heater, lighting or deodorizing will need to be connected to a power source. As these systems combine water and electricity, it is recommended to consult a qualified professional. 

What to look for in a quality bidet toilet seat


To provide optimum comfort, many bidet seats include various heaters. Some have heated seats, which is a nice addition on chilly winter mornings or in colder climates. Some heat the water before spraying, while others even have a hot air dryer for when you’ve finished!


Controlling the seats various functions can range from simple knobs and levers to full digital displays. Bidet-only toilet seats are manually controlled and usually have a single knob for adjusting the pressure. Heated seats with lots of features usually have a more complicated setup. For tech-savvy users, a model with a remote control provides the greatest range of adjustments and may also have personalized memory settings.


GFCI Replacement Plug

As mentioned, a bidet seat needs a water supply. This can usually be taken from the pipework that feeds the toilet. Some seats need an additional electric supply, which is often more complicated. To ensure the safety of all users it should always be connected via a certified ground-fault circuit interrupter (GFCI).

How much you can expect to spend on a bidet toilet seat

Bidet toilet seats are somewhat of a luxury and can be expensive. Expect to pay $60-$100 for a basic model that only sprays and upwards of $300 for a fully-loaded, higher-end option with heaters and other extra features.
