Valve, trim and heads in one box — and the valve goes in the wall
A shower system is a rain head, a handheld, the trim you see and, on the systems here, the rough-in valve that sits inside the wall. That makes it a remodel product: installing it means opening the wall to the valve. The specification that matters most is the valve type: US codes require pressure-balancing or thermostatic protection on shower valves, so the temperature does not jump when a toilet flushes. Then the paperwork an inspector looks for, cUPC and ASME A112.18.1/CSA B125.1, and the flow rate, because California and several other states limit shower heads to 1.8 or 2.0 gpm. The heads come last: a large head on weak pressure drizzles. We compare valve type, head size, outlets, certification, flow and finish.

Head size decides the area covered, on pressure good enough to fill it.
The lowest published price for a valve, trim and both heads in one box; read its paperwork before deciding.
Yes, for every system here. Each includes a rough-in valve that sits behind the tile.
A valve that keeps the hot and cold mix steady when pressure on one side drops, for example when a toilet flushes. US codes require this or thermostatic protection on shower valves.
The one your pressure can fill. On a weak supply, an 8 or 10-inch head beats a 12-inch one.
That depends on the diverter. Most systems here switch between them rather than running both.
2.5 gpm federally; 1.8 or 2.0 gpm in California, Colorado, New York, Washington and several other states.
The published finish is the manufacturer's. This site does not compare it.
The valve type decides whether the shower is safe and passes inspection, the published flow decides where it may be sold, and the head size decides how it feels on your pressure.
The table keeps only the dimensions given by four products in five. Below that threshold, a column measures missing data rather than the product.
