you have not found a great contractor, the great contractor will have built dozens of stramers and be insistant on choosing vaporproofing, and have a plumbing and electrical team in place they will be insistant on A FULL build system.

be very careful and hire wisely A very basic tile steamer built PROPERLY starts at around 20K and the tiler will have a full detailed system in place before they meet you.

This may sound harsh but its for a reason. good luck in your smart hiring choice ,be dilligent in your hiring process. , best.

um my contractor is great, and offers a lifetime warranty on the shower except for the steam generator. they are making it vapor proof and will use wedi, epoxy grout and high grade porcelain tile. he has built many steam showers. they are upgrading our panel to accommodate the generator. The company has been in business 26 years and carries insurance, with an excellent BBB rating. this was the 6th contractor I talked to. I did my research.

I just want to know if anyone has any recommendations for the actual generator unit.

What does your tile professional recommend? Seems strange that he/she is making you research and choose. Your tile pro, who has built dozens of steam showers, should be the one to recommend and buy the best steam generator.

The fact that you are asking strangers on the internet makes me worried for you. If you were DIY-ing it, then asking on the internet can sometimes make sense. But you have pros working for you; this is their job. Why aren’t they helping you? My tile pro would never had allowed me to choose my own steam generator. That’s his job.

If you pick generator, how can your Pro warranty the job. Oh no, all in and Pro takes responsibility for everything. Period. Be careful

just make sure you have a wrrrty for the generator that both the mfg and plumber will wrrty get it in writing if the unit does not work with your adjusted cubic ft. calculations you are also gonna be very unhappy and stuck between tiler plumber and MFG .

Rare a unit the plumber did not purchase from a supply vendor will be wrrty. , rare a plumner will install a unit supplied by client. Regardless do not buy online unless direct from mfg.

You can get defensive, but i was trying to help you avoid a potential issue as i build steamers and have had to have units repaired onsite it is a very risky situation you are proposing and red flag in my experience .Lots at stake.
