Toilet Flange Cost

Also known as a closet flange, the toilet flange is a pipe fitting that both mounts a toilet to the floor and connects the closet to a drain pipe. Made out of brass, cast iron, ABS, PVC, or lead, the flange is mounted most of the time on top of the floor with the hub fixed around the drain pipe. The toilet flange needs to be replaced if water is leaking around the toilet’s base and in this case, it is important to also check the subfloor if it’s wet and spongy. If so, other repairs are also needed before changing anything.

How much does it cost?

This can be done as a DIY job with flange parts being the only expense.  The cost for a flange for your toilet will range anywhere from $5 to $40. This price will usually depend on the brand that made it and the retailer you buy it from.

For example, on Amazon.com a Toilet Flange Repair Kit is between $10 and $20.

If you don’t want to get your hands dirty a professional will charge you around $200, but you should be ready to spend much more depending on how badly damaged is the subfloor, the type, and condition of the pipe, how badly was the flange corroded, your location, or the plumber you hired.

If it’s just a simple replacement of the part without any additional procedures you don’t have to worry all that much about the cost of labor.

This is one of those jobs that you shouldn’t postpone for too long because, with every passing day, the damage the water does to the flooring around your toilet can increase. Replacing this part as soon as you notice something wrong with it is the best way to make sure you won’t have to deal with costly repairs.

How to replace it

First of all, turn off the water supply to the toilet and disconnect the water supply hose, so you can empty the bowl and the tank by flushing the toilet.

Do not lose the bolts that are holding the bowl into the floor because you will need them when you finish the job to make the toilet whole and working again.

After cleaning the floor and the wax from the old flange you can start mounting the new one. New bolts are highly recommended for the new flange to be fixed on the floor.

After pushing a new wax ring into the waste outlet with the narrow part against the toilet, put the closet back in place taking care of the bolt holes to be aligned with it.

Now you only have to mount the toilet into the floor again and turn on the water supply. Over-tighten bolts will crack the toilet, so be very careful!

Things you don’t need but it’s good to have:

  • Lubricant spray – to loosen the bolts
  • Adjustable pliers – help to unscrew the bolts
  • Paint scraper – clean wax
  • Newspaper – dump wax
  • Rubber gloves – protection
  • Mask – protection

Things you will surely need:

  • Wax ring
  • Adjustable wrench
  • Toilet bolts, nuts
  • Plastic cap for bolts

Can I save any money?

The most efficient way to save money is by replacing the flange yourself. As already mentioned, the parts are pretty cheap and on top of that, the job itself is not rocket science at all, so everyone can do it with a little help from a youtube guide.

If you’re hiring a plumber for the first time, he will be more than happy to offer you a deal with the goal to earn you as a permanent client. So don’t be ashamed or afraid to negotiate on pricing.

An important advantage to have before haggling is getting at least three or four quotes from other plumbers. If you don’t find cheaper alternatives, at least you’ll know the price is fair.

If you have several toilets and you have to fix them all or you’re simply in need of multiple repairs, don’t hesitate to ask the plumber if you can benefit from any discounts. The bigger the ‘project’ is the bigger the chance is to get a lower price.

A great way to ensure that you will spend less, in the long run, is to make sure you get a flange that is better rated, even if that means spending a few bucks more on the purchase. Seeing that the range in price for this piece isn’t a considerable one, getting a better-rated piece won’t hit your wallet all that hard, but it will ensure it will last for a longer period of time.
