Toilet replacement cost: what a new toilet costs installed
$250–$600
Most US homeowners report paying between those amounts for a standard two-piece toilet including labor. Wall-mounted, ADA-height, and smart models climb from there. Your quotes will vary by region and what's hiding under the old unit.
A toilet swap is a small-ticket job with a predictable shape: fixture cost + roughly one hour of labor + a handful of cheap parts. The spread in quotes almost always comes from the parts nobody can see until the old toilet is off the flange — and occasionally from picking a $900 toilet at the showroom.
What drives the cost: labor vs materials vs extras
The fixture. Standard two-piece toilets run about $100–$400 at retail; one-piece and designer units $300–$800; wall-mounted carriers and integrated smart toilets clearly above that. Comfort-height and WaterSense models sit close to base pricing now.
Labor. A like-for-like swap is typically $125–$300 of labor — most plumbers bill it as a flat fixture rate rather than by the hour precisely because it's fast and repeatable.
The hidden parts. Wax ring or rubber gasket ($5–$25), new supply line ($10–$25), closet bolts, and a shutoff valve ($15–$40) should be assumed on every replacement. The expensive surprise is the flange: corroded or cracked flanges add $100–$300 to repair, and that's the single most common upcharge on a “simple” quote.
Permits. Like-for-like toilet swaps almost never need permits. Relocating the drain does — and relocation is a whole different, bigger job.
Cost by toilet type
| Type | Typical range (installed) | Notes |
|---|---|---|
| Standard two-piece | $250–$600 | The national baseline |
| High-efficiency / comfort height | $300–$700 | Minimal premium these days |
| One-piece | $350–$850 | Easier to clean, heavier to carry |
| Wall-mounted | $800–$1,850 | In-wall carrier, more skilled labor |
| Smart / bidet-integrated | $600–$2,200 | Nearby outlet (GFCI) may be needed |
| Flange repair add-on | +$100–$300 | The most common surprise line |
DIY vs hiring a pro
Comfortably DIY. Shut the water, flush the tank dry, unsnap the supply, unbolt, lift (toilets weigh 60–100 lbs — use two hands or a friend), scrape, new gasket, set, bolt snug-not-grudging, reconnect, caulk the base perimeter. Tools: putty knife, wrench set, sponge, bucket; $25–$75 of extras. Typical saving: $125–$300.
The mistake risks: overtightening (cracked bowls and tanks are the #1 DIY casualty), reusing a wobbly old flange (rocking toilet = failed seal = floor damage below), skipping the caulking that modern codes require around the base (it keeps water out of the subfloor), and forgetting to check the bowl is level before final tightening.
Difficulty rating: low — the best first plumbing job most people ever do. Call a pro for wall-mounted units, cracked slabs, or any job where the old toilet was set in mastic or the flange looks wrong.
Repair vs replace: where the threshold sits
- Running toilet: flapper $10 or a fill valve $15–$25 — repair, every time. With a service call expect $75–$150.
- Leak at the base: try new bolts and a fresh gasket once ($20); if it still seeps, replace the toilet or fix the flange — don't caulk over a leak.
- Cracks: hairline cracks in tanks can burst without warning. Replace immediately, no threshold math.
- Ancient volume: pre-1994 toilets use 3.5–7 gallons per flush vs 1.28–1.6 today — a real water-bill reason to swap even a working old unit.
Hiring a pro: what a fair quote includes
A fair toilet quote is flat-rate and says so: haul-away of the old unit, new wax/rubber seal and closet bolts, new supply line, inspection of the flange (with a stated price if it needs replacing), base caulking, and cleanup. If an electrician is needed for a smart toilet outlet, that's a separate licensed line item — which is a good sign, not padding.
Red flags: reusing the old wax ring “to save you money,” no caulking afterward, quoting without asking about flange condition, and refusing to demo-test a suspected leak before naming a price.
Frequently asked questions
How much does it cost to replace a toilet with labor?
Standard swaps: $250–$600 all-in for most US homeowners. Wall-mounted and smart models run higher; flange repairs add $100–$300.
How long does it take a plumber?
45–90 minutes for a clean swap; longer with mastic bonds, flange repairs, or floor patching.
Can I replace a toilet myself?
Yes — it's the classic first plumbing job. Don't over-tighten, replace the gasket, check the flange, and caulk the base.
Repair or replace a running toilet?
Repair ($10–$20 parts). Replace only for cracks, base leaks that keep returning, or pre-1994 water-guzzlers.
