Further, once a walk-in bathtub is installed, it may be difficult to remove the bathtub for transfer to a new location if the user later moves from one home to another. Even if the walk-in bathtub can be transferred, it may still not have the correct door configuration and/or drain orientation for the new location.
- The present disclosure generally provides modular walk-in bathtub systems comprising a plurality of configurable components that may be connected together on-site to meet a user's preferences and/or the plumbing requirements of a particular location. Modular walk-in bathtub systems according to embodiments of the present disclosure may include, but are not necessarily limited to, door tubs, walk-in tubs, transfer tubs, and/or slide-in tubs. Modular walk-in bathtub systems according to embodiments of the present disclosure may enable: passage of the configurable components through various sized doorways; on-site configuration during installation of the walk-in bathtub system to provide a left-hand drain or right-hand drain orientation; on-site configuration during installation of the walk-in bathtub system to provide an in-swing door, an out-swing door or a two-in-one door; removal and/or reinstallation of the walk-in bathtub system in a different location; and/or stackable storage of the configurable components.
