The steps
- In-home assessment. The installer measures the space, checks the drain and supply lines, the floor and the electrical panel, and confirms the door swing has room to open.
- Choosing the tub and features. Door type, seat height, jets and drain speed all matter. Ask for fill and drain times and the water volume.
- Permits. Plumbing or electrical changes may need permits, depending on your city or town. Ask who pulls them.
- Removal. The old tub is removed and disposed of, and surrounding wall or floor may need repair.
- Plumbing. Drain and supply lines are aligned to the new tub. Moving them costs more than leaving them where they are.
- Electrical (if needed). Jets, heated seats and in-line heaters can require a dedicated circuit and ground-fault protection.
- Setting and sealing. The tub is leveled, secured and sealed, and the door is adjusted so it seals correctly.
- Testing and walkthrough. The installer fills the tub, tests the door seal, jets and drain, and shows you how to use it.
Things to check before installation day
- Water heater. Walk-in tubs commonly hold 40 to 80 gallons, and 40 gallons is generally cited as a minimum heater size. Ask whether yours is enough.
- Water pressure and pipe size. Low pressure or narrow pipes make filling slower. Some installers use larger supply lines or a rapid-fill valve.
- Floor strength. Water weighs about 8.3 pounds per gallon, so 50 gallons is about 420 pounds before the tub and the person are counted. For an upper-floor bathroom, ask the installer to confirm the floor can carry it.
- Bathroom access. Can the tub physically get through your doors and stairs?
- Bathroom use during the job. Plan where to bathe and use the toilet.

FAQ
How long does walk-in tub installation take?
Many installers describe about one to three days for a straightforward job. Bathrooms that need plumbing moved, floor work or electrical upgrades take longer.
Do I need a permit?
It depends on your local building department and the work involved. Ask the installer who will handle permits and what your city or town requires.
Can a walk-in tub go upstairs?
Often yes, but the floor must support the weight of a full tub and a bather, so ask the installer to check.
