  We find an exact solution of BPS wall in five-dimensional supergravity using
a gravitational deformation of the massive Eguchi-Hanson nonlinear sigma model.
The warp factor decreases for both infinities of the extra dimension. Our
solution requires no fine-tuning between boundary and bulk cosmological
constants, in contrast to the Randall-Sundrum model. Wall solutions are also
obtained with warp factors which are flat or increasing in one side by varying
a deformation parameter.
