We’ve incorporating nearly all suggested features in our master bath and like many of the chosen baths. We disagree however with the hard surface bench seating though. The wooden seat are far warmer, more comfortable to sit on, and usually have more rounded front edges. Also, it is easier to slightly slope them for water runoff. Even a portable or mounted fold down wooden seat is a better option than a tile/marble/granite seat. We’ve had both and have re-done the hard-surface/cold-surface ones with wood.
