    DETAILED DESCRIPTION OF EMBODIMENTS

    (12) A description of embodiments of the present invention will now be given with reference to the Figures. It is expected that the present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope.

    (13) The present invention discloses an apparatus or rectangular fitting (shown in FIG. 5) configured to convert a traditional or conventional bathtub or tub 19 (shown in FIG. 1B) into a soaking tub or a soaker. The soaker may be defined as a tub with a depth allowing for a user to soak or submerge without displacing water over the tub edge. In a standard bathtub, soaking or submerging usually results in the displacement of water due to the lack of depth. The present invention is an apparatus to house water above a top edge of a bathtub wall, comprising a water-impermeable fitting adhered to a top-surface of at least one bathtub wall with a water-proof seal. The water-impermeable fitting adhered with a water-proof seal over the top surface of any of the bathtub walls results in allowing a user to fill the bathtub with water above a top edge of the bathtub wall without leaking or displacing water, effectively converting a standard bathtub into a soaker. In some embodiments, the fitting—or at least a portion of the fitting—may be lowered or extended up. In other embodiments, the fitting—or at least a portion of the fitting—may be removable. In yet other embodiments, the fitting is fixed—immovable or unremovable. The apparatus is further configured to enable a user to customize the bathtub 19 to store and increase the water level to a plurality of pre-determined heights. Referring to FIG. 1A, a front piece or a first fitting 10 of the rectangular fitting or apparatus is disclosed. In one embodiment, the front piece 10 is configured to securely adhere to a front top wall of the bathtub 19. In one embodiment, the front piece 10 comprises a first portion 11, a pair of corner fittings 12, a handle 14, a pair of locks 16, an adhesive 43, and a middle portion or a second portion 18. In one embodiment, the middle portion 18 of the first fitting 10 is configured to extend upward and downward to a plurality of pre-determined heights by a user. In some embodiments, the middle portion 18 is configured to extend upward and downward, but not limited to, a pre-determined height and/or to any user-preferred heights by the user. In one embodiment, the handle 14 is securely affixed to the middle portion 18 of the front piece 10. The handle 14 is configured to enable the user to lift upward and downward the middle portion 18 of the front piece 10 to a plurality of pre-defined heights. In one embodiment, the pair of locks 16 are flexibly affixed to the pair of corner fittings 12. The pair of locks 16 are configured to enable the user to lock the middle portion 18 of the front piece 10 at the desired heights. In some embodiments, the fitting may be of any number of shapes that conform to any number of bath tubs. In a preferred embodiment, the fitting is rectangular to conform to a standard conventional bathtub. However, square, elliptical, or circular tubs, while unconventional, are known to exist as high-end bathroom fixtures. Additionally, the bottom portion of the fitting may be coated or lined with an adhering material, other than an adhesive, in order to adhere or affix to the top surface of any of the the bathtub walls. The key determinant for an optimal adhering material is that it must prevent any water leakage over the top edge of the bathtub wall.

    (24) Now in reference to FIG. 9. In a preferred embodiment, regardless of any of the various configurations—as described above, claimed, and illustrated in any of FIGS. 1-8—an overflow stopper may be provided, wherein a rubberized stopper is dimensioned to fit within the overflow valve that is customary on most standard tubs as a way to allow the water level to surpass the point of the overflow valve. The overflow valve is intended to drain water from a filling tub that is about to reach a certain level dangerously close to overflowing over the tub. By inserting this stopper, the water level may surpass this demarcated point and allow the tub to convert into the soaker as described, claimed, and illustrated in the present claimed invention. The stopper may be configured in any number of ways to accomplish drainage prevention of the overflow valve. In one configuration, it may be a suction-type cup that caps and forms a seal over the drainage. In another embodiment, it may be an insert that completely forms a clog over the drainage. In other embodiments, the stopper may have an elongated tube in an upright position slightly shorter than the height of the fitting walls as a way to allow overflow water to drain back into the drainage and allow the filling tub to only fill to a certain level, slightly below the height of the fitting to prevent overflow of the fitting. In other embodiments, the stopper may have a lever that allows a user to flip up or down the lever as a way to start draining the tub to a lower level, yet higher or at level with the overflow drain.
