“Not published” means Redwood Outdoors does not state this figure on the product page we read. We do not estimate missing specs or take them from review sites.
Our take
Needs no electricity at all. If your plunge lives on a deck with no outlet, this is the shortlist.
Worth knowing before you buy
No sanitation is included — Redwood sells a bromine kit ($249) and a water-balancing kit ($149) separately. It was showing out of stock when we checked.
We have not physically tested this unit. Everything above is either a manufacturer-published specification or an observation drawn from comparing those specifications across brands.
