How Do Walk-In Tubs Work?
If you are considering a bathroom remodel to enhance accessibility or elevate your bathing experience, a walk-in tub could be the perfect solution. But how do walk-in tubs work? Below, we’ll cover all the basics, including a step-by-step guide to using walk-in tubs and an overview of the various types and features available.
Walk-In Tub Definition
Walk-in tubs cater to individuals with limited mobility, disabilities, or chronic pain. Unlike traditional bathtubs, walk-in tubs have a built-in watertight door that allows users to enter and exit easily over a low threshold. These tubs are made from the same materials as other tubs, such as fiberglass or acrylic. However, they come with additional safety features, such as grab bars, nonslip surfaces, and built-in seats for extra security.
Walk-in tubs can help those with disabilities maintain their independence or make it easier for caregivers to assist them. They can also help older adults age in place comfortably, reducing the risk of slips and falls and providing peace of mind for loved ones.
Many walk-in tubs have a compact design that allows them to fit into the same space as your existing tub, with the smallest walk-in tubs measuring 26–32 inches wide and 40–48 inches long. However, models with built-in seating or jets may be deeper or wider than a standard tub.
Walk-in tubs may also have handheld showerheads, heated seats, and hydrotherapy, aromatherapy, or chromotherapy features. Air jets or water jets, essential oil diffusers, and colored lights can help create a soothing, spa-like experience.
How Walk-In Tubs Work
Walk-in tubs may seem confusing at first, but using them is easy once you learn the basics. Here’s a step-by-step guide:
- Enter the tub. Open the door and carefully step into the tub, using a grab bar or handrail for stability.
- Close the door. Once you are inside the tub, close and secure the door. Make sure it is tightly sealed.
- Fill the tub. Ensure that the tub drain is sealed, then turn on the faucet to fill the tub with water. Test the temperature with your hand and adjust as needed.
- Use the features. As the tub fills, activate any extra features you wish to use, such as air jets or underwater lights.
- Bathe safely. Sit on the built-in seat to soak or bathe, using the backrest for support.
- Drain the tub. When you are finished, locate the drain control or lever and activate it. Some tubs feature a fast-drain technology that makes this process much quicker.
- Exit the tub. Wait for the tub to fully drain, then unlock and open the door. Hold onto the grab bars or handrail as you lift up from the seat and exit the tub.
Types of Walk-In Tubs
You can choose from several types of walk-in bathtubs, each designed to suit different needs and preferences. We cover a few of the most common types below.
Bariatric tubs are designed for individuals with larger body sizes. They have a higher weight capacity and a wider doorway and seating area than standard bathtubs to comfortably accommodate those with bariatric needs. However, they are not necessarily longer than other tubs.
Soaking tubs are among the simplest walk-in tub designs. Since their function is to provide an immersive bathing experience, they are typically deeper than other walk-in tubs. They do not have jets, and most can fit in a standard tub alcove. However, larger sizes are available.
Hydrotherapy tubs are soaking tubs that feature strategically placed water jets to deliver deep-tissue massages. These whirlpool tubs can help alleviate muscle tension and promote relaxation. Another variation is an air bath, which generates streams of bubbles from the bottom of the tub to increase circulation.
Two-seater tubs are larger than standard walk-in tubs because they are built to accommodate a couple rather than an individual. The two bathers typically sit facing each other, so each end of the tub has its own backrest. These tubs can be more complicated to install because the faucet extends over the side of the tub rather than being on one end, like most tubs.
Wheelchair-accessible tubs have ADA-compliant features that make them larger than regular tubs. For instance, they feature a larger, outward-opening door that provides direct access to the tub seat for those with mobility issues. This makes it easier for those with a wheelchair or Hoyer lift to transfer in and out of the tub.
If you’re seeking a more accessible bathing solution, remember that walk-in tubs aren’t the only option. Several simple and affordable alternatives to walk-in tubs exist, such as shower chairs, transfer benches, and bath lifts.
Walk-In Tub Installation Process
The first steps in installing a walk-in tub are assessing your bathroom space and existing plumbing, making any necessary modifications, and removing the old bathtub. Once they have prepared the space, the installers will position the tub, anchor it securely, and connect it to your plumbing system. They will also make electrical connections for any lights, jets, or other tub features.
Next, the installer will test the functionality of your new tub, including the door seal and water pressure. They will then address any issues and add the finishing touches, such as caulking. The entire installation process typically takes only one to three days. Single-day installations are possible if your bathroom requires few or no modifications.
