Hi Rounder, thanks for the inquiry. The bench is approx 34" in diameter, and 18" tall. The bench was custom built on site, if you'd like more info on how we did that, please click here https://www.houzz.com/discussions/the-circular-wet-dry-bench-is-great-do-know-how-the-base-was-built-possibly-schluter-products-dsvw-vd~182242

Thanks

Thanks Steve. My shower room is smaller and this will sit between the shower and a foot spa basin we intend to build in a wet room. I expect 20 inch diameter as large as I can accomodate there. No shower doors. I want to wrap it in mother-of-pearl tiles

Sounds great, and best of luck with your project! Let me know if there's anything else I can answer for you.
Cheers,
Steve
