(57) A method for replacing a bathtub (1) with a shower platform providing the step of
removing the bathtub (1) with entire bathtub body (3) from the containing walls (5a-5d),
obtaining a recess (4) defined by a containing wall, which is removed up to leaving
a shoulder (11). The step of removing the bathtub (1) does not involve the original
taps (10). Furthermore, the fragments and debris (7) produced during the demolition
of the walls (5a-5d) are stored in the recess (4') defined by the shoulder (5a-5d),
which form the shoulder (11), thus avoiding to dispose of the produced debris and
the fragments. The layer of fragments (7) can then be flattened to provide a base
frame (8) on which a shower platform (20) is then located. For making the base frame
(8) substantially homogeneous it is possible to add filling material, for example
polyurethane foam (50). The shower platform (20) has size such that it is oversized
with respect to the standard size of a bathtub (1). In this case, the shower platform
(20) is subject to a preliminary cutting step for fitting it to the size of the shoulder.
At the uncovered surfaces (25), when removing the bathtub (1), a lining sheet (15)
is applied.
