Toilet Replacement & Installation in Orange County & Los Angeles

A toilet that rocks, leaks at the base or runs all night is usually telling you something about the seal, the flange or its own age. Target Plumbers repairs what can be repaired and replaces what can’t, in homes and businesses across Orange County and Los Angeles. We measure the rough-in, check the flange under the old bowl, and give you a written price before any work starts.

Repair or replace? Start with what the toilet is doing

What you notice Usually the fix Replace instead when…
Runs on and off, or hisses after flushing New flapper or fill valve Parts for that model are no longer made
Water on the floor around the base New wax ring and closet bolts; flange repair if it’s broken The bowl itself is cracked
Drips between the tank and bowl New tank-to-bowl gasket and bolts The tank is cracked
Rocks or shifts when you sit Reset on a new seal, shims, flange repair The subfloor under it has rotted
Weak flush, needs two flushes Clear the rim jets and trap, adjust the fill level It’s an early low-flow model that never flushed well
Hairline crack in the porcelain None; cracks spread Always: a cracked tank or bowl can split without warning
Uses 3.5 gallons or more per flush (usually stamped inside the tank) Repairs keep it working You want lower water bills, a rebate, or you’re remodelling a pre-1994 home

Toilet clogged rather than broken? That’s a job for drain cleaning . If the toilet keeps clogging and other drains gurgle, the problem is usually further down the line.

California rules your new toilet has to meet

  • 1.28 gallons per flush or less. Since 2014, toilets sold in California must be high-efficiency models (California mandates 1.28 or less for toilets). Every toilet we install meets that limit.
  • Older homes and remodels. In buildings built on or before January 1, 1994, toilets using more than 1.6 gallons per flush are “noncompliant” under California Civil Code §1101.1–1101.9 (SB 407). Single-family homes have had to replace them since 2017, and replacement is triggered when a building permit is issued for alterations. Sellers must disclose noncompliant fixtures (SB 407 text).
  • Rebates. SoCal Water$mart rebates start at $40 per toilet for premium models using 1.1 gallons per flush or less, when they replace a toilet using 1.6 gallons or more. Amounts vary by water agency (SoCal Water$mart). Choose a qualifying model before you buy; we can install a toilet you’ve already picked.

Choosing a toilet that fits your bathroom

Choice What to know
Rough-in Measure from the finished wall to the center of the floor bolts. 12 inches is standard; 10- and 14-inch rough-ins turn up in older houses and need a matching toilet.
Bowl shape Round bowls save a couple of inches in small bathrooms; elongated bowls are more comfortable for most adults.
Seat height Standard bowls sit about 15 inches high. “Comfort” or “right height” models are about 17 to 19 inches, easier for tall users and anyone with knee or hip trouble.
Flush type Gravity flush is quiet and simple to repair. Pressure-assisted is louder but strong, useful for busy commercial restrooms. Dual flush lets you use less water for liquids.
One-piece or two-piece One-piece is easier to clean and has no tank-to-bowl gasket to leak; two-piece costs less and is easier to carry into tight spaces.
Wall-hung The tank sits inside the wall on a steel carrier, so it’s a remodel job that means opening the wall, not a same-day swap.
Bidet seat or smart toilet Most need an electrical outlet beside the toilet, and some need a tee on the water supply. Check before you order.

What a toilet replacement includes

  1. Measure and confirm the model. Rough-in, space to the side walls, and where the supply valve is.
  2. Shut off, drain and remove the old toilet, and plug the drain so sewer gas stays out.
  3. Inspect what was underneath: the flange, the subfloor and the old wax ring tell us whether the toilet was leaking.
  4. Fit a new seal and closet bolts, plus a new braided supply line. We replace a seized or dripping shut-off valve if you approve 
  5. Set, level and secure the new toilet, then flush it repeatedly and check every joint for leaks.
  6. Clean up and take the old toilet away

What we often find under an old toilet

  • A cracked or rusted flange. Cast-iron rings rust through and plastic ones crack. We repair it with a flange repair ring or replace it, because a new toilet on a broken flange will rock and leak again.
  • A soft subfloor. Years of slow leaking rot the wood. Small spots can be reinforced; larger ones need the floor repaired before the toilet goes back.
  • A flange set too low after new tile. We raise it with an extender so the seal compresses properly.
  • A corroded angle stop. Older valves often won’t close fully, which is a good moment to replace them.

If water has been leaking under the floor for a long time, we may suggest a leak check on the line as well.

Toilet repairs we handle

  • Running toilet: flapper, fill valve, flush valve and chain adjustment.
  • Leaking at the base: reset on a new wax or wax-free seal, closet bolts and flange repair.
  • Tank leaks: tank-to-bowl gasket, tank bolts and supply connection.
  • Loose or broken seat and handle: replaced while we’re there.
  • Fill valve that keeps failing: high household water pressure wears these out; a water pressure regulator check can stop the cycle.

What affects the price of a new toilet

  • The toilet itself, or whether you’ve already bought one.
  • One-piece, wall-hung or bidet models, which take longer to fit.
  • Flange, subfloor or shut-off valve repairs found under the old toilet.
  • Stairs or tight access, and how many toilets we replace in one visit.

Toilet replacement questions

How much does it cost to replace a toilet?

The total depends on the toilet you pick, whether we supply it or you do, and what we find when the old one comes off: a broken flange, a soft subfloor or a corroded shut-off valve adds work. We give you one written price before we start, and a second written price if the flange or floor needs repair.

A straight swap on a sound flange usually takes a couple of hours, including testing. Flange repair, a new shut-off valve or a wall-hung toilet adds time.

No. California’s retrofit law treats toilets that use more than 1.6 gallons per flush as noncompliant in buildings built on or before January 1, 1994. A 1.6-gallon toilet is not on that list, although any new toilet sold in the state today must be a high-efficiency model.

Often, yes. SoCal Water$mart offers rebates starting at $40 for premium high-efficiency toilets that use 1.1 gallons per flush or less and replace a toilet using 1.6 gallons or more. The amount depends on your water agency, so check the program site before you buy.

Repair it first in most cases. A running toilet usually needs a new flapper or fill valve, which costs far less than a new toilet. Replacement makes sense when the porcelain is cracked, the toilet uses 3.5 gallons or more per flush, or the same parts keep failing.

It’s the distance from the finished wall behind the toilet to the center of the floor bolts, usually 12 inches and sometimes 10 or 14 inches in older homes. A new toilet has to match it, or it won’t sit against the wall properly. We measure before you buy.

Yes, removal of the old toilet is part of the job
