Bidet Installation Estimate FAQs

What’s the difference in cost between a bidet attachment, a bidet seat, and a standalone bidet?

A bidet attachment costs $20 to $100, a bidet toilet seat installation costs $250 to $1,000, and a standalone bidet costs $700 to $2,600 installed — the standalone unit is significantly pricier since it requires its own dedicated plumbing lines.

Does a bidet actually save money over time?

Yes — a bidet can save you money by reducing your toilet paper use; you can expect to save $50 to $150+ per year with a bidet or bidet attachment, after accounting for the added water use.

Do electric bidet seats need special electrical work?

Yes, often — if your setup requires new electrical wiring, installing a new electrical outlet costs $150 to $350 total on average, since electric bidet seats typically need a nearby GFCI outlet.

Are standalone bidets practical for small bathrooms?

Not always — standalone models take up as much space as a standard toilet and may not work in small bathrooms, making bidet attachments or seats a better fit for space-constrained layouts.

Can I install a bidet attachment myself to save money?

Bidet attachments are generally the most DIY-friendly option since they connect to your existing toilet’s water supply line without major plumbing work, unlike standalone units, which should be installed by a professional to ensure the bidet connects properly to existing water lines and prevents leaks that damage floors or walls.

Is a bidet toilet seat easy to retrofit onto an existing toilet?

Yes — bidet toilet seats look like a standard toilet seat but come with a wand and nozzles, and they’re very easy to install and more affordable than standalone units, making them a popular retrofit option.

What drives the cost toward the higher end for standalone bidet installation?

At the high end, some people spend as much as $2,500 on a wall-mounted bidet with extensive plumbing and finishing work required — wall-mounted units and dedicated plumbing runs are the main cost drivers.

Joel and his team went above and beyond to make sure they helped us fix the gas leak. Joel is a man of his word and came through on his promise.

Very expensive. Make sure you establish the price up front. They did some work on gas pipes, which was specialized so the prices weren't so horrible.

They never called my property manager, or myself, to ask if they could do an additional estimate while at my property. I was shocked. Companies cannot go around doing estimates.
