What a normal installation includes

On a simple job, the installer removes the old tub, sets the new one in the same spot, connects the drain and water lines, seals it, and tests the door. If the tub has jets or a heater, it also needs a power source. Some tubs come with wall panels or extensions to fill the gap around a smaller unit.

The three costs that surprise people

1. Hot water

Walk-in tubs hold more water than a standard tub. If your water heater is small, the bath can run lukewarm. A larger or tankless heater may be needed.

2. Electricity

Jets, air systems, heated seats and inline heaters run on electricity. Many tubs need their own GFCI-protected circuit. If your panel is full, that adds cost.

3. Permits

Local rules differ. In the City of Las Vegas, for example, a permit is needed to alter piping inside a wall or floor, to install or replace a water heater, and to run new wiring for an outlet5. A simple fixture swap with no concealed piping changes may be exempt there. Ask your installer who pulls the permit.

How to keep installation costs down

  • Pick a tub that fits the existing alcove. Most are built for a 60-inch space.
  • Ask whether removal, disposal, wall panels and electrical work are included.
  • Get the water heater checked before you choose a tub size.
  • Get at least two written quotes that list labor separately.

Questions people ask

Usually one or two days for a straight swap. Electrical, plumbing or wall work can add time.
Can I install a walk-in tub myself?
Some tub-only models are sold for self-installation, but most need plumbing and electrical work, and some warranties require professional installation. Check the warranty before you buy.
