Walk in Bath FAQs

General questions about bathrooms, fitting and MobilityPlus

A walk-in bath is a bathtub featuring watertight doors, allowing you to step in via a low threshold without having to lower yourself down or step over a high rim. They are available as compact “tub style” baths where you sit up comfortably, or traditional full-length models where you can lie down. They create a much easier bathing experience for the elderly or those with generic mobility issues.

The price varies depending on your specific needs and bathroom configuration. We offer a price match guarantee, but factors affecting the final cost include the specific model style (deep soak vs. full length), installation complexity, and luxury additions such as chromotherapy lighting or Spatherapy features. Contact us for a precise quote based on your space.

You simply open the watertight door, step in via the ultra-low entry, and sit on the integral seat. Once the door is closed and sealed, the bath fills with water. Thermostatic controls ensure the water is the perfect temperature before you start filling. When you are finished, two rapid drains empty the water quickly so you can open the door and step out safely from your walk-in bath.

The main difference is that you must be inside the bath while it fills and empties. However, our rapid-fill taps and fast-drain technology minimise waiting times. Most of our customers find that the therapeutic benefits, added safety, and independence greatly outweigh the short wait time.

They are specifically designed to create mobility-friendly bathrooms. The primary advantage is safety; low-threshold doors and grab rails remove the struggle of climbing in and out. Features like anti-slip flooring minimise fall risks, while the upright seating position provides comfort for those who struggle to stand for long periods in a shower.

Walk-in baths are designed to be leak-proof when installed and fitted with leak-proof seals. Proper installation by a professional is essential to prevent leaks and ensure that the bath functions as intended.

Yes, most walk-in baths have a built-in seat, which allows users to sit comfortably inside the tub while it fills up with water. To prevent scalding and maintain a consistent temperature, walk-in baths are equipped with thermostatic bath fillers.

The time it takes to fill a walk-in bath will depend on the size of the tub and the water pressure in your home. On average, a walk-in bath can take anywhere from 5 to 15 minutes to fill.

The lifespan of a walk-in bath can vary depending on the quality of the materials used; it could last you a lifetime. Our walk-in baths are covered by a 15-year warranty.

After draining, walk-in baths have a door that opens either inward or outward, allowing users to easily step out of the tub. Some models may also have a built-in seat that can be raised or lowered to assist with getting in and out of the tub.
