"Ambassador Plumbing was my first choice and the only one of three companies to respond to my request for a quote. Paul came within a couple of weeks and did a fine job of replacing my Mansfield toilet with their recommended Kohler one that met my specifications. I'm very pleased with not just the toilet but the work too. (Note: Ambassador does not honor the Angi 5% coupon displayed on their site.)"

"Kirkwood Plumbing is represented by very capable plumbers, does its work without surprises, and has a very strong commitment to customer satisfaction. For those reasons I give it an A rating. Below is the story. I needed to have the upper stack of the toilet replaced and have a new toilet installed. Of the 3 companies I called, only Kirkwood Plumbing sent a master plumber, a plus. Paul was very observant and identified the least intrusive manner I was chip to complete the tasks, which in an old home, was not simple. Although not the least expensive bid, I accepted it based on the confidence Paul inspired. That was a very good decision. Greg arrived on time at the appointment date and immediately went to work. He is a capable plumber who worked very hard and efficiently, a plus. He had a great manner with his assistant and it was a pleasure to observe them working together. Greg was determined to leave me with running water and a functional toilet by the time he had to leave, and that was much appreciated. To that end, however, he did not take the time to go back to get the correct saw to cut through the cabinet and wall and thus created sufficient dust particles to saturate the air. Nor did he go back to get the correct shut off valve so he didn't install one. Those were negatives. After he left, I noticed that I could no longer open the faucets in the bathroom so I got in touch with Kirkwood plumbing. They immediately rescheduled a return visit, a positive. Greg attended to the issues that remained but couldn't repair the faucet problem. Although he was convinced that he did not cause this problem, he called Jason in to take over, another plus. Jason is a very thoughtful, methodical plumber who calmly and efficiently repaired the problem. I don't know if he thought this issue was a separate or related problem but he refused any additional payment that I offered, another plus."

Toilets FAQs, answered by experts

On average, it costs between $150 and $300 to fix a toilet that’s leaking at the base, including supply charges. If the flange is intact, the cost is between $150 to $200. If the flange needs to be replaced, you can expect an extra $50 or so. The actual price will depend on the hourly rate your plumber charges.

Yes, a toilet, sink, and shower can share the same vent. This is a common installation method that can simplify plumbing and save space. However, there are important considerations. The vent and associated plumbing must be large enough to handle the demands of all fixtures without compromising the vent's effectiveness. Additionally, the toilet should always be located downstream of all other fixtures. Because requirements can vary and space might be limited, it is essential to check your local building and plumbing codes and consult with a qualified plumber to ensure the installation is done correctly.

To test for toilet leaks, use water coloring in the water tank and see if the water slips into the bowl from the tank. This test will indicate if there’s a problem with the flapper or refill tube. You can also put water coloring in the bowl of the toilet to see if there is a leak there. If there is, you should see the colored water on the outside of the toilet bowl or on the floor. 

Most codes require 15 inches on either side of the toilet's centerline (from the wall or vanity) and at least 21 to 24 inches between the toilet and the wall in front of it. These codes ensure that your toilet is easy to use and access, even in small bathrooms. Check your local building codes for the exact measurements required. 

The average cost to replace a toilet seal ring is around $50 to $200 if you hire a pro to do the job. If you do it yourself, you’ll only need to pay for the supplies. Wax rings alone cost anywhere from $5 to $25 at hardware stores and can save you a lot of money compared to having a professional installation. At the same time, a licensed plumber knows how to properly install your new wax ring to prevent premature issues down the line.
