BACKGROUND OF THE INVENTION Such a bathtub lift is known from German Patent DE-A-41 30 323. The bathtub lift disclosed therein includes a backrest that pivots around a shaft pin, and is provided with a mechanical operation mechanism thereof.
In the simplest case, the tub lift is connected by a hose to the tub faucet fitting instead of the hose in a handheld shower accessory. Such a bathtub lift facilitates the operation of opening the cold water cock by operating the switching lever on the bathtub cock attachment part. The disadvantage here is that the handheld shower accessory cannot be used. A further disadvantage is that a large number of outer manual control valves are used on the wall side of the tub to assist the caregiver, especially when lowering the lifting plate and thus when the plate is below the liquid level. Is difficult to reach. The "left-handed" and "right-handed" schemes can also be made without problems, but the problems can still occur with other bathtub arrangements to fit different bathtub installation locations.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to easily convert a bathtub from the right side bathtub outlet to the left side outlet,
And the provision of replacements or retrofits of older equipment so that they may be suitable for other pressure water operated options.
