Standalone bidet
A standalone bidet costs $250 to $800 for the unit alone or $700 to $2,600 with professional installation. This traditional bidet model installs next to a regular toilet and requires its own plumbing lines. A standalone bidet looks like a toilet without a tank or lid.
The average cost to install new plumbing lines alone is $450 to $1,800 per fixture.
Bidet toilet
A bidet toilet costs $500 to $1,500 before labor. Installation brings the total cost to $650 to $2,100 if you’re replacing an existing toilet. A bidet toilet combines the functionality of a regular toilet and a bidet into one unit, saving space and allowing the use of existing plumbing lines.
Bidet toilet seat
A bidet toilet seat costs $150 to $700 for the seat alone or $250 to $1,000 installed. Also called a “washlet”—a term trademarked by Toto, a popular toilet manufacturer—a bidet seat replaces your existing toilet seat with a seat that includes bidet functionality.
Bidet seats are more cost-effective and space-saving than standalone bidets.
Non-electric bidet toilet seats are typically the most DIY-friendly to install.
Bidet attachment
A bidet attachment alone costs $20 to $100 and is easy to install on most existing toilets. The attachment connects to the toilet’s water line and installs between the toilet seat and the toilet bowl. Bidet attachments typically have one or two manual controls, varying pressure levels, and some use warm water.
Bidet spray attachment
A bidet spray attachment costs $20 to $50 for the unit alone or $100 to $250 installed. This basic spray attachment uses a T-valve that branches off the toilet’s water line and mounts on the toilet’s side or tank. Bidet spray attachments require handheld use and have no warm water option.
Bidet prices by brand

Bidet installation cost factors
The following factors affect the cost:
Type – Most bidet seats and bidet sprayer attachments are easy to DIY install. Installing a standalone bidet or a bidet toilet may require more advanced plumbing and electrical work, where professional installation is best.
Material – Higher quality materials cost more but lengthen the bidet’s lifespan.
Extras –Features like self-cleaning, night lights, deodorizers, air dryers, and multiple wash modes increase the cost.
Warm vs. cold water – Bidet units that use warm water cost more but provide a more comfortable experience.
Brand – Large, well-established brands like Toto, Kohler, and Tushy typically charge more but may offer better quality and product support.
Permits – Some bidet attachments do not require a permit, but most cities require a permit if you’re installing a new fixture where there wasn’t one before, or a unit requiring new plumbing lines or electrical wiring.
DIY vs. professional installation
Bidet toilet seats and bidet attachments are easy to install, with most installations taking less than an hour. Standalone bidets and bidet toilets require a bit more strength and skill with plumbing lines and possibly electrical wiring, depending on the model and your existing space.
Plumbers charge $45 to $150 per hour.
Electrician hourly rates are $50 to $130 per hour.
The total labor cost to install a standalone bidet is $150 to $900, similar to new toilet installation cost. Keep in mind this price is for plumbing labor only. If your setup requires new electrical wiring, installing a new electrical outlet costs $150 to $350 total on average.
Consider bundling your bidet installation with other household projects. Most plumbers and electricians have minimum project fees.
Bidet pros and cons
Installing a bidet is good for the environment as well as for improved personal hygiene. Bidets require minimal water and can reduce the amount of toilet paper you use. However, standalone models take up as much space as a standard toilet and may not work in small bathrooms.

Getting estimates from bidet installers
Before hiring a bathroom plumber or handyman plumber near you for your bidet installation, be sure to:
Compare at least three estimates from licensed plumbers who’ve been in business 5+ years.
Hire a plumber with consistent positive feedback on HomeGuide and Google.
Only hire a company that can provide proof they are licensed, insured, and bonded.
