A mirror cut to size by a local glass shop was installed inside a tile frame we and designed on the wall above the vanity and grouted in. The same glass shop installed the frameless shower wall. The six-head spa shower went in without any trouble. It is a very clever design that fits right over a standard shower fitting.
Ambient lighting was provided by a shadowless fluorescent fixture recessed into the ceiling. Pendant task lighting was installed over the vanity mirror. We used compact fluorescent bulbs in these for shadowless illumination and efficiency. (Learn about lighting in bathrooms and kitchens at Designing Efficient and Effective Kitchen Lighting). The shower got its own recessed lights wired into the general lighting circuit. The existing builder-grade (read "cheap") vent fan was replaced by a super-quite unit installed in the attic and controlled by a timer next to the light switch.
