As long as you accout for the heat loss for the type of stone with a bigger steam generator, you will be fine. You should be able to go on websites like MrSteam, Steammist or Amerec and see the calculations needed when accounting for heat loss. Or talk to a showroom constulant at a plumbing supply company (like Ferguson Enterprises), they can help you with what size generator you wll need.

Consider Thermasol the leader in steam technology. Their steamers do not require any tricky math, just cubic feet. http://www.poshhaus.com/store/m/28-Thermasol.html

I am also available to size and discuss steam with anyone, nearly anytime either on this forum, or email me @ rob@poshhaus.com

Thank you - I appreciate your comments :-)

Just a note about the Vapor 238 on the bathroom wall - it is made by the company "C2", not Benjamin Moore

What is your exact concern? If you correctly water/vapor proofed the shower walls, ceiling and the floor before you installed the stone you will be fine.

I also see you have Mr. Steam unit, so make sure it sized properly.

I am redoing my steam shower and was wondering if I need to replace the vent/light fixture with the same? I have never used the ventilator, didn't make sense to pull out the steam, and it eventually quit working. My tile contractor thinks they are required and I don't agree.

Hi Jeff,

The fan inside your steam shower is NOT recommended. It may create the "chimney" effect and your steam will not stay in the steam shower but instead it will escape through it. I would recommend a ceiling fan right outside the steam shower above your door/transom. You do want air flow to dry out your shower after you're done showering/steaming. Check out this link, click on "I'm the installer" and see what are the recommended steps to build steam shower correctly. www.thermasol.com/solutions

Thanks Martin. I have a fan outside the steam shower now and rarely need that. Most times a take a cold shower after the sauna and that condenses the steam down. And I always keep the shower door propped open to allow the shower to dry out after each use.
