Size is a claim about your pressure, not about luxury · review
A solid metal 8-inch rain head on 1/2-inch NPT brass threads, at 2.5 gpm — the most expensive here, and the only one whose thread is named.
Of the four rain heads here, this is the only one that states 1/2-inch NPT, the thread American shower arms use, and that it is brass. Others say standard or quote a metric thread. It means the seal is made by the threads with tape, the way a plumber expects.
That is the federal maximum, and more than California, Colorado, New York, Washington and several other states allow for sale. Outside those states it gives the heaviest rain on this shelf. Inside them, choose the SparkPod or the Voolan at 1.8.
Solid metal, 1.6 pounds, and a finish described as commercial grade. The page does not name the metal or give a warranty term, though the first bullet is headed Built to last a lifetime.

Not as listed: 2.5 gpm exceeds the 1.8 gpm limit for shower heads sold there, and the 2.0 gpm limits in Colorado and New York. The SparkPod and Voolan on this shelf ship at 1.8 gpm.
The tapered pipe thread used on American and Canadian shower arms. HammerHead names it, and states the threads are brass. Several cheaper heads quote a metric G1/2 thread or no thread at all.
It does not crack at the thread, the most common failure of plastic heads, and holds its finish. Whether it is worth about $45 more than a stainless face like the Voolan depends on how long you keep a shower head.
Same category, nearby prices, between bathroom fittings. What remains is the specifications every one publishes — half empty, a column is no use.
