How Much Does Bidet Installation Cost? [2025 Data]

Bidet Installation Cost by Type

There are a variety of bidets on the market with different functionalities and features. They’re made of varying materials and connect to your plumbing in different ways. Choosing a bidet will be the most significant cost factor for your bidet installation. 

Stand-Alone Bidet

This original type of bidet looks very similar to a standard toilet minus the lid or tank. A stand-alone bidet typically sits adjacent to the toilet and is usually made of ceramic. Typical costs for a traditional stand-alone bidet are $500 to $1,500, with an additional cost of around $220 for installation and plumbing materials. 

A stand-alone bidet also requires dedicated plumbing lines that are separate from the toilet. Adding these lines can be quite expensive. Expect to pay around $1,180 for additional bidet plumbing. 

Bidet Toilet

Two-in-one bidet toilets combine the function of a standard toilet with a bidet. They save space and eliminate the need for dedicated plumbing lines, thus avoiding a costly upgrade to the bathroom’s plumbing. 

Costs for a bidet toilet range as widely as they do for toilets, with models available in different materials and with varying features. The cost of a bidet toilet ranges between $1,200 and $2,000; models vary from basic ones to those loaded with features that help create a home spa bathroom, like built-in deodorizers, night lights, dryers, oscillating massage jets, and even Bluetooth speakers.

Bidet Toilet Seat

A bidet toilet seat looks like a standard toilet seat, but it comes with a wand and nozzles. They’re very easy to install and are more affordable than adding a stand-alone bidet or toilet bidet combo. 

Prices for bidet toilets range from $170 to $650, reflecting the various options available for these luxury items. Whereas models that offer basic functions may only cost a few hundred dollars, bidet toilet seats loaded with features can eclipse $600. High-end bidet toilet seats come equipped with oscillating nozzles, multiple nozzles, heated seats, night-lights, water temperature controls, and bidet pressure control. 

Bidet Attachment

With a price range of $80 to $120, a bidet attachment is a budget-friendly way to add a bidet function to a bathroom. This mechanism installs easily to the underside of a standard toilet seat and attaches to the toilet's fresh water supply line. It doesn’t require batteries or an electrical connection to function, and some models can also hook up to warm water. 

Handheld Spray Nozzle

Another affordable option is a handheld spray nozzle. his DIY bidet consists of a sprayer with a hose that attaches to the toilet's supply line and mounts to the side of the toilet tank. While the handheld spray nozzle allows you to direct the stream of water, it can be awkward to use, especially for those with limited mobility. That said, a handheld spray nozzle bidet is easy to install and relatively inexpensive at $40 to $120.

Bidet Installation Cost by Size

Bidets come in different shapes and sizes to fit different toilet models. The most common standard sizes are round seats, which are 17 inches or less, and elongated seats, which are 17 inches or more.

You may occasionally see slightly higher prices for the larger elongated size. However, it's more common to see one bidet model offered in both round and elongated styles for the same price.

DIY Bidet Installation vs. Hiring a Pro 

The more elaborate stand-alone bidets and bidet toilets often require professional installation by a local toilet installer, but there are many DIY-friendly alternatives—and a homeowner can almost always install bidet attachments. With most professional plumbers charging between $80 and $200 per hour, the total labor costs for bidet installation cost about $220. 

If you’re installing a simple fixture or your home plumbing skills are well-honed, DIY installation will knock that amount off the final bill. If you’re not totally confident you can pull it off, save money in the long run by opting for a professional installation since the cost of a basic toilet repair starts at around $230. 

If the bidet requires the addition of a new electrical outlet in the bathroom, there are no circumstances under which you should attempt to do the job yourself.
