Kinda Sketchy, Sauna is Nice Though

I'm happy to update my star rating later if it turns out this should have been plainly obvious to me:

I ordered a Renu Therapy sauna, and one from Almost Heaven showed up.

The model name didn't even match, it was all Almost Heaven product, install manuals, etc.

I bought this assuming Renu was an original equipment manufacturer... Instead they're just white labeling another brand and tacking $2k onto the price point?

If I knew that was going to be the case I would've just ordered it directly from Almost Heaven - feels like I got ripped off to be honest.

That all to say, it's a nice sauna


Thanks for your honest review. We apologize for the fact you were unaware that Renu is a reseller for Almost Heaven Saunas. While we do manufacturer our cold plunges ourselves, many customers want a heat element to go along with their cold plunge, so we do offer the AH saunas. We don't try to hide this fact at all, but again I apologize if it wasn't made clear to you.

As a consolation, I have issued you a retroactive 10% discount. You should receive that within 3-5 business days.
