Toilet installation costs $350 to $800 on average for the toilet and professional installation. Toilet prices alone start as low as $100 for a basic two-piece unit to as high as $20,000+ for the most high-end smart model with all the bells and whistles.

If you’re DIY-savvy, replacing a toilet yourself can save $150 to $900+ on labor. However, hiring a professional ensures the job is done correctly, safely, and up to code.

Toilet installation takes 2 to 3 hours on average when hiring a professional. If you’re installing a wall-hung toilet or a toilet in a completely new location, installation can take 4 to 6+ hours due to the extra plumbing and drywall work needed.

While some toilets last 50+ years, the average lifespan of most toilets is 10 to 20 years. Some parts, such as the chain, flapper, and wax seal may need replacing before that 10-year mark. Consider replacing an older toilet even if it’s still functioning, as today’s models are much more efficient and cost less to run.

You can technically use a toilet right after installation. However, most professionals recommend waiting 48 to 72 hours for the sealants to dry completely. Some caulking dries in just a few hours, while other types take 24+ hours to cure and dry, so it’s best to confirm the correct wait time with your installer.

With the many plumbers and plumbing service companies available, follow these guidelines to help you find the best toilet installation service near you:

• Compare 3 to 5 toilet installation estimates with similar details.
• Choose a licensed, insured, and bonded plumbing service with high ratings on HomeGuide and Google.
• Avoid going with the cheapest installation estimate as this may signal low-quality work.
• Ask for a detailed contract and warranty in writing before the installation begins.
• Don't pay in full until the job is complete.

Asking the right questions will help you choose the best plumber for your new toilet installation:

• How long have you been in business?
• Is your company licensed, insured, and bonded?
• What experience do you have installing this type of toilet?
• How quickly can you install the toilet?

• Does the estimate include removing the old toilet and disposing of it?
• Is your quote based on an hourly rate or is it a flat fee for this service?
• What other costs might come up during the installation?
• How long should we wait to use the toilet after installation?
• Do you offer a warranty, and what does it cover?
• Do you submit the manufacturer’s warranty registration?
