Water does change density with temperature, so it is denser the deeper you go. I doubt there’s a normal bowling ball weight that would have the right density for it to float at some random depth though.
Water is compressible; it has a bulk modulus of about 2.2 GPa. So at the 1086 bar at the bottom of the Mariana trench (~109 MPa), it’ll have compressed about (109 / 2200) ~= 5%. Materials with a different bulk modulus to water may start to float at sufficiently high depths.
Water’s not compressible, so the density doesn’t change with depth. Either the bowling ball is denser than water or less dense than water.
