There are several available accessories that are available for most quality walkin tubs. A swivel seat is one of the most common, which makes it much easier to turn your body into and out of the tub. Many people use a bath lift so that they can independently take a bath, but they are also very popular among caregivers. If you are a caregiver, then you will likely want to ensure that the lift has a seat belt and chest restraint.
When you are finished in the bath simple press the button and you will be raised to the top of the bath to exit. The control pad is waterproof as it may get splashed and you won't have to worry. Some inflatable baths have suckers underneath to stop the lift from moving about and keeping where you want it to be. Unlike other walkin tubs, this has no metal parts which you may hit your arm or leg on, can also get cold and sometimes possibly rusty.
The original walkin tubs were an upright barrel that could be filled with water and was equipped with a stool to sit on. In Japan, this is still the concept used on their bathtubs, while western civilization took their tubs in a different direction with a shallower design and longer length. In modern western bathtubs a person can recline until the water reaches their chin. The barrel was not a comfortable, requiring the subjects to remain in the seated position.. The new deeper corner bathtubs allow for reclining to get into a comfortable position with the depth needed for enough submersion.
A bath lift is one of the best ways to ensure safety in the walkin tubs. They make it easy to transfer into and out of the tub. For safety reasons most use battery power and a completely sealed remote control that also floats. A quality bath lift has a built in battery gauge and will not lower unless the battery is strong enough to go back up again. This ensures that you will never be stuck in the bathtub. Most also have a reclining back so that you can relax in the premier bathtub safely and in a naturally ergonomic sitting position.
The bathtub rail should fit all baths and is easy to get out of the bath if anyone else uses the walkin tubs without a lift. Some inflatable bath lifts you can take with you traveling as they are designed to be packed compactly and easy to store. No installation, quick to set up and use.
