For the past year I've been creating my dream home, and I'm happy to be sharing some of the models with y'all that I have developed along the way.
Here are two models of a shower stall, varying in door placement; one opens on the side and the other at the end. The doors have their origin at the proper pivot point.
The model includes shower head, separate hand-held spray head, soap/shampoo rack, and grab bar. You'll find a bit of, uh, amateur topology on the spray head, a few ngons, but otherwise the model is pretty clean.
The open source texture, the tile, is packed into the blend file. It originally comes from http://tiled-bg.blogspot.com/ , although I modified the size of the image, using multiples of the original to arrive at a higher resolution.
The models are offered with no restrictions.
