How Much Does It Cost to Replace a Toilet? [2026]

The cost to replace a toilet runs about $300 to $800 installed, with a national average near $372, per Bob Vila (citing Forbes/HomeAdvisor data) and HomeGuide. This page is for the homeowner deciding whether to swap a toilet themselves or hire it out – and whether to replace at all or just repair what is broken. The good news: a like-for-like swap is one of the more DIY-able plumbing jobs. The catch is what is hiding under the old toilet.

How Much Does It Cost to Replace a Toilet?

A standard professional replacement – toilet, labor, supplies, and haul-away – typically totals $300 to $800, averaging about $372 (Bob Vila, range $224-$532); HomeGuide puts the all-in install at $250-$750, and NerdWallet at $300-$800. Premium fixtures, older homes that need a new flange or shut-off valve, or high-cost metros push totals toward $700-$1,238 (Homewyse).

These are ranges, not a quote – the figure you pay depends on your region and what the plumber finds under the old toilet. For a quick read on your specific job, try the free Plumbing Repair Cost Estimator.

What Drives the Cost (the honest spread)

Location is the single biggest swing. High-cost metros run well above the national average – New York and Boston price 30-50% above national (Northeast all-in totals of $600-$1,400), and coastal California metros like San Francisco and Los Angeles commonly run $500-$1,300, per Angi regional data. Midwest and Southern markets are the floor, roughly $250-$450 for a plumber. That is an honest spread, not false precision: on top of any regional baseline, severity – a corroded flange, a stuck shut-off valve, or a soft subfloor – can add a few hundred dollars.

Repair vs. Replace – the Honest Math

Most toilet problems are cheap repairs, not replacements. The average toilet repair is $60 to $200 (most people pay about $125), per Fixr – a flapper is $60-$120, a fill valve $60-$150, a wax ring $60-$150. Replacing the whole toilet is $300-$800 installed. The honest rule of thumb: replace rather than repair when the repair would top about $300, the toilet is 20-plus years old, you have had repeated repairs, or the bowl (not just the tank) is cracked. There is one more factor a sticker-price comparison misses: an old 6-gallon-per-flush toilet is a standing cost. Swapping it for a 1.28 gpf WaterSense model saves more than $170 a year and about $3,400 over its lifetime, per the EPA – which can pay back the replacement on its own. To see what a running or inefficient toilet is costing you, our Water-Waste Calculator puts a dollar figure on it.

Should You DIY It or Hire a Pro?

A straightforward swap is genuinely DIY-able – This Old House rates a toilet install 1 out of 5 (Easy) at about 4-6 hours. Doing it yourself costs roughly $120 to $370 in parts and supplies versus a $300-$800 pro total – an honest savings of about $180 to $450, almost all of which is the avoided labor. The catch: that savings only holds if the flange, the supply valve, and the subfloor are sound. The moment you hit a corroded flange, a stuck shut-off valve, or a rotted or uneven subfloor, the job stops being a $20-wax-ring swap, and a botched seal that leaks under the floor can cost far more than the labor you saved. If you are not sure which toilet you have or whether it is a standard rough-in, our how to identify your toilet guide is the place to start.

When to Call a Pro

This is the part that decides the cost. Call a plumber when:

• The subfloor is soft, rotted, or uneven around the drain – a wobbling toilet means the floor cannot hold a watertight seal, and water seeping under the fixture rots the subfloor and stains the ceiling below. Subfloor repair is structural, not a fixture swap.
• The closet flange is cracked, rusted, or sits below the finished floor (it should sit about 1/4 inch above) – a proper flange repair runs $145-$300 (Bob Vila) and can require cutting into the drain pipe.
• The shut-off valve is stuck, corroded, or weeping, or the supply line is an old soldered or rigid line – replacing a valve means shutting the line and can turn a 1-hour job into a plumbing repair.
• You smell sewer gas or see repeated leaks after reseating the toilet – this points to a venting or drain issue, not a wax ring, and needs a pro to diagnose.
• You are moving the toilet’s location (not a like-for-like swap) – relocating a toilet means new drain and supply runs and costs $2,500-$3,500 (Bob Vila), firmly pro and permit territory.
• Local code requires a permit and inspection for the work – some jurisdictions do, and a failed inspection on DIY work costs more to redo.

How to Choose and Vet a Plumber

If the job is past that line, vetting protects the price. Tell the plumber exactly what you see – “old toilet wobbles, I think the flange is bad” – so the quote reflects the real job. Ask whether the quote includes haul-away of the old toilet and a new flange or supply valve if needed, since those are the line items that move the total. Confirm the plumber is licensed and insured, and get the price in writing. For a job this size, two or three quotes are reasonable; a wide spread usually means they are assuming different things about the flange and subfloor, so ask each what they are scoping.
