Installing a bidet costs $640 on average, but the range is wide: from about $80 for a simple attachment to $2,000 or more for a bidet toilet.1,2 The type you choose decides the price. A stand-alone bidet that needs new plumbing lines costs the most.2,3 Prices below are national averages* for 2026.

*National averages, not local quotes. Your price depends on the bidet type, whether new water and drain lines are needed, and local plumber rates.

HomeAdvisor and Angi print the same average, range and type prices, so they are one dataset and count once. HomeGuide is independent and runs higher on seats and stand-alone units. One Angi summary line prices seats at $400 to $1,500, which contradicts its own table ($170 to $650), so I used the table.1,2,3

Heated seats and warm-water models need a GFCI-protected outlet next to the toilet.2 If you do not have one, plan for an electrician visit.

Homewyse prices a plumbed-in stand-alone bidet, with a vitreous china fixture, labor and supplies, at $1,073 to $2,054 total. That is higher than the averages above because it assumes a full fixture install.4

DIY or hire

An attachment or handheld sprayer is a genuine DIY job: it connects to the toilet’s existing water line with a T-valve and takes under an hour.1,3 Stand-alone fixtures and bidet toilets need a plumber. Home Depot’s bidet attachment category is a good place to compare models and prices before you decide.
