It is pretty lame that companies resort to Houzz to try and drum up business. The whole point of the site is for people to get ideas and collaborate on designs. If your idea of collaboration is getting my phone number and contact information... pfffft.

Agree - this company is very irritating in the way they market their services without giving up a single piece of info.

There are many other designers on Houzz, of course...
Here is my opinion... 9.5' x 5' sounds fine. In fact, I am currently mid-project on a shower / tub area that is 10' x 5.5" . This size is great for the "wet-room" idea, and quite lavish, which when it comes to bathrooms I encourage! The other suggestion I will make is that you keep in mind how many gallons per minute the shower heads and sprays will flow when on; then, make sure the drain can handle all of that water!
Go for it, Sounds like a great project!
