Would really depend on where you live due to construction cost differences but in Calgary, Alberta, Canada it would be around $20,000-$25,000. There is great cost associated with the Steam machine, the travertine, !0mm custom glass doors, high cost labour and the dual head plumbing. Hope this helps.

This came out very nice. I am thinking of adding this to the master bath we are designing as part of our home renovation. Can you recommend a manufacturer for the steam machine? I live in San Francisco but I'm sure they would be national.
