How much does it cost to install a walk-in tub?

A walk-in bathtub is a tub installed in an alcove that allows users to walk or transfer in with no barrier. Rather than a fixed front wall like a standard tub, a walk-in tub has a door that opens outward to allow entry. The occupant sits inside the tub either on the floor of the tub or on a built-in 1 seat. When the door is sealed, the tub can then be filled with water. Some walk-in tubs offer therapeutic options such as airbath or whirlpool jets, while others are strictly for soaking.

A walk-in bathtub is an ideal addition to most bathrooms for people who have mobility issues and cannot safely enter a normal tub by stepping over the edge, or by seating themselves on the edge and swinging their legs in. People with disabilities, the elderly, those who have mobility issues due to conditions such as obesity, people with dementia, and anyone who would have difficulty entering a tub full of water safely can benefit from using this tub, as can their caregivers.  

The average cost of a standard walk-in tub installed is around $6,000 - $8,000. For a tub installed with options such as hydrotherapy, the cost rises to around $12,000. The final cost you will pay can be influenced by the size and type of tub, whether or not you include a surround, whether an electrician is required to hook up and place a motor, and whether you are replacing an existing tub, or making room for a new one.

Basic features

A basic walk-in tub is meant to fit into an alcove installation with little retrofitting required for the rest of the bathroom. Therefore, the tub itself will likely measure around 60-inches in length, and up to 30-inches in width. The depth of the tub will vary, but most tubs are designed for soaking, which makes the average depth around 36-inches to 40-inches, although some very deep tubs may be available at 46-inches for a deep soak.

The door of a walk-in tub is meant to swing outward into the bathroom, although a few models offer an inward swinging door for bathrooms where space is tight. When the door closes, it seals completely to keep the water in the tub, and cannot open again until the tub is drained, which means there are no accidental spills or floods. Most doors measure around 15-inches in width, although specialty tubs with custom doors are available from some manufacturers if needed.


Just like standard bathtubs, there is a range of options available to you in walk-in tubs.

CombinationAllows users to switch between air or water jets as needed$7,000-$10,000


While there aren't as many manufacturers for walk-in tubs as other types, there are still plenty to choose from, including low and high-end models.

The installation of a standard walk-in tub into a typical retrofit bathroom is usually straightforward. The old tub will be removed, along with the row of tile (if applicable) that adjoins it on the walls. Because the new walk-in tub is likely to be much deeper, or higher, than the old tub, you will likely need to retile or replace the walls of the tub area as well, particularly if you plan on using the tub as a shower as well. In most cases, the cost of this is comparable to a standard bathtub installation, which typically takes from 6 to 8 hours at around $85 per hour on average, with many people paying around $1,000 for a standard installation. For a whirlpool or airbath installation, however, the cost can be significantly higher, up to $1,500 - $2,000 for placement of the motor and running of the electricity.  This is because the motor will need to be set nearby, as well as hooked up properly.

Most baths easily retrofit into the space already occupied by an alcove tub, so no major remodeling is necessary beyond reconfiguring the stall. However, there may be some additional considerations to make, including:

  • Plumbing: upgrading your pipes to a ¾-inch diameter will enable the tub to fill more quickly. This can be expensive, however, costing between $4,000 to $6,000 to complete. In addition, you may need to upgrade your hot water heater, as these tubs can hold up between 50 and 80 gallons. A tankless heater will supply an endless amount of hot water for around 3,500, while a standard heater that will supply 50 gallons of hot water costs between $600-$800.
  • Electrical: the drain pump 2 and any jets will require a dedicated circuit of 15 amps and a GFCI grounding for use in the bathroom. Electricians charge about $65-$85 an hour, and an upgrade of the circuit may cost between $1,300 and $3,000 if needed.

Enhancement and improvement costs

  • If you plan on tiling the tub into the surround, ask for a tile flange to be included in the tub. This flange allows for a watertight installation of the tile to the tub. Flanges cost between $100 and $500 depending on type and placement.
  • Longer tubs or two-seater tubs are also available to make bathing easier for caregivers or families, costs start at around $5,000.
  • Neck rests may be available as an add-on item for some tubs, with costs starting at around $100.
  • Some tubs may also offer a surround to allow for shower conversion. Costs for a surround start around $1,000.

Additional considerations and costs

  • One drawback to a walk-in tub is the fact that you must enter before the tub fills, which may be cold or uncomfortable; the door is meant to be sealed when the tub is filled with water.
  • Entry to the tub is around 6-inches on average, but some models may offer a lower entry of around 4-inches at no additional cost; check the manufacturer’s specs before ordering to be sure
  • Depending on your needs, you may find that a ceiling lift for around $3,000 can assist you with entering a standard tub. Or, a curbless shower for around $6,000 can allow for walk-in or wheel-in entry with barrier. Shower benches and shower chairs are also available with costs ranging from $50 to $500, allowing you to bathe in a standard shower while seated.
  • Because walk-in tubs are often a specialty item, most people who sell them also offer installation.
  • Most tubs with a mechanical feature will require some degree of maintenance, such as running the jets with specialty cleaners that cost around $10. You may also need to have a plumber or electrician out every few years for routine maintenance or repairs.
  • Every manufacturer has a different warranty. Look for those that offer a lifetime guarantee on the seal of the door to avoid leaks. Jets and motors may have separate warranties, and some companies may allow you to purchase an extended warranty to cover the tub longer.
  • The US Department of Agriculture has a program that may offer financial assistance to elderly homeowners looking to make upgrades in their homes, such as a walk-in tub.
  • Always look for a tub that has a CSL/UL Certification.
