How Much Does a Plumber Charge to Replace a Toilet? (2026)

Whether your toilet is cracked, constantly running despite repairs, or you're upgrading to a more efficient model, knowing the cost upfront helps you budget and avoid overpaying. Toilet replacement is one of the most common plumbing jobs, and pricing is fairly standardized.

Toilet Replacement Cost Summary

Most homeowners in LA pay $400–$600 total for a standard toilet replacement including the toilet, parts, and labor. High-end installations with premium fixtures can run $800–$2,000+.

What Affects the Cost?

Toilet selection

The toilet itself is usually the biggest cost variable. Key choices:

• One-piece vs. two-piece: One-piece toilets ($200–$800) look sleeker and are easier to clean. Two-piece ($100–$500) are more common and cheaper.
• Round vs. elongated bowl: Elongated bowls are more comfortable but need more space. Same price range.
• Water efficiency: Look for WaterSense-certified toilets (1.28 GPF or less). LA offers rebates for high-efficiency toilet installations through LADWP.
• Comfort height: ADA-compliant “comfort height” toilets (17–19 inches) are popular for taller adults and aging-in-place planning. Slight price premium.

Plumber labor

A straightforward toilet swap takes a plumber 45–90 minutes. Labor costs increase if:

• The old flange is damaged — flange repair adds $50–$150
• The floor needs repair — water damage or rot around the base adds $100–$400
• Supply line or shutoff valve replacement — corroded valves add $50–$150
• Moving the toilet to a new location — this requires new plumbing rough-in ($500–$2,000+) and is a different scope than a replacement

Old toilet disposal

Most plumbers include haul-away of the old toilet in their price. If they don't, ask upfront. Toilets are heavy (50–100 lbs) and you can't put them in regular trash. LA allows toilet disposal through bulky item pickup from LASAN.

When to Replace vs. Repair

Replace your toilet if:

• Cracked tank or bowl — can't be reliably repaired
• Constant running despite replacing flapper and fill valve (see our running toilet guide)
• Frequent clogs — older low-flow toilets (first-gen 1.6 GPF) are notorious for weak flushes
• Visible wobbling that tightening bolts doesn't fix — the flange may be broken or the floor is rotting
• It's a water hog — pre-1994 toilets use 3.5–7 GPF. Replacing with a 1.28 GPF model saves thousands of gallons per year

Repair instead if:

• The issue is a worn flapper, faulty fill valve, or loose handle — these are $5–$20 fixes
• The toilet is less than 10 years old and works well otherwise
• A single clog that can be cleared with a plunger or auger

Can I Replace a Toilet Myself?

Yes, toilet replacement is a moderate DIY project if you're comfortable with basic plumbing. The process:

1. Shut off water and flush to empty the tank and bowl
2. Disconnect the supply line and unbolt the toilet from the floor
3. Remove the old toilet (heavy — get a helper)
4. Scrape off the old wax ring and inspect the flange
5. Place new wax ring on the flange
6. Set the new toilet on the bolts and press down firmly
7. Tighten bolts evenly (don't overtighten — porcelain cracks)
8. Connect the supply line and turn on water
9. Check for leaks at the base and supply connection

DIY saves $150–$350 in labor. The main risk is cracking the toilet by overtightening bolts or discovering a damaged flange that needs professional repair.

LADWP Toilet Rebates

The Los Angeles Department of Water and Power offers rebates for replacing old toilets with high-efficiency models. Check LADWP's current rebate program for eligibility — rebates have historically ranged from $75–$250 per toilet, significantly reducing your out-of-pocket cost.

Hiring a Plumber for Toilet Replacement

For a straightforward swap, any licensed plumber can handle it. When getting quotes:

• Ask if the price includes the toilet or labor only
• Confirm haul-away of the old toilet is included
• Ask about flange inspection — if it's damaged, you want to know the additional cost before they start
• Verify they'll test for leaks before leaving

Frequently Asked Questions

How much does a plumber charge to replace a toilet?

In Los Angeles, plumber labor for a toilet replacement runs $150–$350. This covers removing the old toilet, installing the new one, and testing. The toilet itself and parts are additional. Total installed cost is typically $350–$700 for a mid-range toilet.

How long does it take to replace a toilet?

A professional plumber completes a standard toilet swap in 45–90 minutes. DIY takes 1–2 hours. Add time if the flange needs repair or the floor has damage.

Do I need a permit to replace a toilet in LA?

No. A like-for-like toilet replacement in the same location does not require a permit in Los Angeles. If you're moving the toilet to a new location (new rough-in plumbing), that does require a permit.

What toilet do plumbers recommend?

Most plumbers recommend Toto Drake (reliable, efficient, mid-price around $250–$350) or American Standard Champion (powerful flush, good value at $200–$300). Both are WaterSense-certified and widely available. Avoid the cheapest builder-grade models — they clog more and don't last as long.
