"The technician arrived at the start of the 2 hour window. On time! Very professional. Explained options for dealing with my toilet leak. I chose to replace the toilet and gave him guidlines for the new toilet. He went to Home Depot, acquired the toilet returned promptly and installed it in a timely manner. After which he broke down and explained the itemized charges. After paying for the work thru my credit card, I received an e-mail summary right away...One major concern that I had in hiring Western Rooter & Plumbing was that their technicians had been vaccinated for Covid 19. I had been referred to Western earlier this year by my condo HOA for a common area leak repair in my unit. I was assured by the dispatcher that the technician coming to my condo was vaccinated against Covid. So when I had this toilet leak problem 6 months later that I had to pay for, out of a multitude of plumbing companies, I went back to Western Rooter & Plumbing after receiving the same assurance."

"Jose from JRC Plumbing is wonderful to work with. Not only is he an expert in his craft, he’s professional, friendly, and provides great communication. The tube spout broke off in our bathroom. He was able to identify the problem, provide a clear plan of action, and give very reasonable pricing. Our tube spout was quickly fixed, and he patched the wall that needed to be cut into to reattach the pipe, leaving our home better than it was. I will definitely be reaching out to Jose at JRC Plumbing again."

"Johnny was on time, came fully prepared, friendly, and had a great attitude. Ignore those expensive "smell good" plumber commercials! Replaced 2 toilet flanges and reset both toilets for a third less than competitor's quote! I'm not looking forward to more plumbing problems in this 60 year old house, but I now know who to call!"

"Jonathan was a great hire. He came and worked with my schedule and came on a quick short notice. He came for a clogged toilet and swapped my garbage disposal. The next day we clogged the toilet again and he came back within an hour to fix it again for no charge. Pricing is very reasonable and is much lower than other plumbers. I wouldn’t hesitate to hire him again. I plan to have my pipes looked at with a camera because I can’t have this keep happening."

"Wow, so professional, courteous, and helpful! Not only was Ricky a skilled worker, but he was also just an overall easy guy to work with and talk to. Sometimes it's awkward having strangers come into your home for hours at a time to work, but it was not awkward at all. He gave great advice on what to do and what NOT to do, and our toilets are working beautifully. Since we are new homeowners he also walked us through the ins and outs of our main water valve and water heater. I will definitely hire Do It Right Plumbers again!"

"Very grateful for Fed! My Momâ s house had an issue with water not draining properly. Called Fed for a quote; he showed up the next morning and got to work on the issue right away. He was working by himself for awhile since it was Sunday, and had to dig through tons of rocks and roots since the land in our area are filled with stones. There were roots in the sewer line as well as buildup in the pipes; the pipes were so clogged that there was barely what seemed to be 1/8th or so of the pipe where the outgoing water/waste could flow through. He replaced parts of the line with pipes which roots would not be able to penetrate through, which gave us peace of mind as there are a lot of trees in our area. Fed and his team also added a sewer access and he replaced the filters in the toilet tanks as well. Thank you so much for helping us resolve this huge plumbing issue! Fed was honest, reliable, and friendly. Would highly recommend!"

Toilets FAQs, answered by experts

Emergency plumbers charge a significantly higher rate than for standard service, typically 1.5 to 3 times the normal hourly cost. You can expect to pay between $100 and $500 per hour, with an average of around $200 per hour. In addition to the higher hourly rate, many plumbers charge a flat emergency service or trip fee, which can be between $150 and $300. The final cost depends on the timing of the call; prices are highest for major holidays, followed by weekends and after-hours service on weekdays. For a complex job on a major holiday, a master plumber's rate could reach as high as $600 per hour.

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. 

If you notice water leaking down the side of the bowl or tank and you don’t notice any cracks in the porcelain, the odds are that it’s condensation. If you notice water around the base of the toilet, this points to a leak. Check for loose bolts. A sewage odor may also indicate a broken toilet flange.

The cost of making a bathroom accessible can be $3,000 to $25,000, but you could spend as much as $50,000 building a brand-new ADA-compliant bathroom. Some bathroom accessibility upgrades to consider include:

  • Installing grab bars: $100–$500 

  • Lowering cabinets and vanities: $1,200–$2,500

  • Installing modified doors: $700–$1,500

  • Installing a modified toilet: $400–$1,000

  • Installing an accessible sink and faucet: $100–$1,000

  • Adding a walk-in tub: $1,100–$17,000

  • Converting a bathtub into a walk-in tub: $350–$1,000

  • Installing a wheelchair-accessible shower: $2,000–$7,500

  • Installing a shower ramp: $16–$300

The cost to install a new toilet typically runs from $225 to $530. This doesn’t include the price of the toilet itself, which can cost $90 to $1,500 depending on the model and features you choose. You can save money if you choose to install a toilet yourself. However, you might want to hire a pro for this project.

"Due to the many complexities of replacing a toilet flange, it is typically a job best left to the pros," says Jeff Botelho, Angi Expert Review Board member and plumber. "Many times it isn't as simple and straightforward as 'pop off the old one and pop on a new one' because the flange is either glued on (PVC/ABS), soldered on (brass/copper), or caulked in place with a lead & oakum joint (cast iron) and none of these things can be easily reversed without years of training and repetitive practice."
