Why Plumbing Installation Timelines Matter

Understanding the expected duration of your plumbing project is important for several reasons:

• Scheduling: Knowing how long your water or bathroom will be out of commission helps you plan your daily routine.

• Budgeting: Longer projects may mean higher labor costs or additional expenses for temporary accommodations.

• Project Coordination: Plumbing often needs to be sequenced with other work (like electrical, drywall, or tiling).

• Peace of Mind: Clear expectations reduce stress and help you avoid surprises.

Whether you’re in a bustling city like New York (zip code 10001) or a suburban area like Plano, TX (zip code 75023), professional plumbers can help you understand what’s involved and how long it will take.

Typical Plumbing Installation Timelines by Project

Toilet Installation

Average time: 1–3 hours

A straightforward toilet replacement in a finished bathroom usually takes 1–2 hours, including removing the old unit, prepping the flange, and installing the new toilet. If there are complications-like a damaged flange, uneven floor, or corroded shut-off valve-it may take longer.

Faucet or Sink Installation

Average time: 1–3 hours

Replacing a kitchen or bathroom faucet is usually a quick job, often completed in under two hours. Installing a new sink, especially if it involves cutting into countertops or modifying plumbing, can take 2–3 hours.

Dishwasher Installation

Average time: 1–2 hours

Most dishwasher replacements are straightforward, but if new plumbing or electrical lines are needed, or if the cabinetry must be modified, it may take longer.

Water Heater Installation

Tank water heater: 2–4 hours
Tankless water heater: 4–8 hours

A standard tank water heater replacement typically takes 2–4 hours, including draining the old tank, disconnecting and removing it, and installing the new unit. Tankless water heaters are more complex-they may require new gas lines, venting, or electrical upgrades, extending the timeline to a full day.

Shower or Bathtub Installation

Average time: 4–8 hours (simple replacement)
1–3 days (full remodel)

Replacing a tub or shower with a similar unit can often be completed in a day. Custom tile work, new plumbing lines, or moving drains can extend the project to several days.

Whole-House Repiping

Average time: 3–7 days

Repiping an entire home is a major project. The timeline depends on the home’s size, the number of bathrooms, the type of pipes (PEX, copper, etc.), and whether the house is occupied. In a 2,000-square-foot home in Chicago (zip code 60614), expect 4–7 days, including patching walls and cleanup.

Sewer Line Replacement

Average time: 1–3 days (trenchless), 3–5 days (traditional excavation)

Trenchless methods are faster and less invasive, while traditional excavation takes longer due to digging, pipe replacement, and restoration.

Garbage Disposal Installation

Average time: 1–2 hours

A straightforward swap can be done quickly, but wiring or plumbing modifications may add time.

Water Filtration or Softener Installation

Under-sink filter: 1–2 hours
Whole-house filter/softener: 2–4 hours

Factors That Affect Plumbing Installation Timelines

Project Complexity

Simple replacements (like a faucet or toilet) are fast. More complex jobs (like repiping or tankless water heater installation) require more time for planning, permits, and execution.

Home Age and Condition

Older homes often have outdated or corroded pipes, non-standard fittings, or hidden issues that can delay installation. For example, homes in San Francisco (zip code 94109) built before 1950 may require extra work to bring plumbing up to code.

Accessibility

Easily accessible plumbing (such as in a basement or crawl space) speeds up the process. Plumbing hidden behind walls, under floors, or in tight spaces takes longer to access and repair.

Permits and Inspections

Some projects require permits and city inspections, which can add hours or days to the timeline. Your plumber should handle permitting and coordinate inspections.

Material Availability

Specialty fixtures, custom tubs, or unique pipe fittings may need to be ordered, causing delays. Always confirm product availability before scheduling installation.

Coordination with Other Trades

If your project is part of a larger remodel, plumbing may need to be sequenced with electrical, carpentry, or tiling work.

Weather and Regional Factors

In cold climates like Minneapolis (zip code 55401), exterior work or main line replacements may be delayed by weather.
