Victoria 3 comes with an additional figure, V3-to-V2, which is grouped and jointed like Victoria 2. V3-to-V2 has no body morphs, but she has the same body-shape as Victoria 2, and can wear Victoria 2's clothing.

The tub is probably from SAMS 3D, as Jaager says. It could also be from cal's site, wg3d.com; a complete bathroom scene with old steel washtub is currently available there.
