sumerain two-handle Roman tub faucet review

A two-handle deck-mount Roman tub faucet at 12.16 GPM, ICC-ES certified, with a 600,000-cycle cartridge.

By Jean-Benoit Buisson

In brief

What it is: Two-handle Roman tub faucet in brushed nickel for deck mounting, delivering 12.16 GPM at 60 PSI, designed for 3-hole setups with 1-1/4 inch diameters on 8 inch centers; a certified solid brass valve body with metal handles, ICC-ES PMG certified and compliant with ASME A112.18.1/CSA B125.1-2018 for plumbing supply fittings, which the maker states is the same standard as cUPC certification; a drip-free MS ceramic cartridge tested for 600,000 uses with a 4-29/32 inch spout reach, the maker recommending its 8-3/8 inch spout reach version for large bathtubs; two lever handles for temperature and flow control
Verdict: Twelve point one six gallons a minute — 2.7 times the slowest faucet here — with a 600,000-cycle cartridge and ICC-ES certification to the plumbing standard American codes require. And the only maker on this shelf that tells you to buy a longer-reach version if your tub is wide.

Who it’s for: A Roman tub deck with three holes on 8-inch centers, where certification and cartridge life matter most

What the maker puts in writing

“This tub filler faucet delivers a high flow rate of 12.16GPM@60PSI to fill your tub quickly”
Designed for 3-hole setups with 1-1/4 inch diameters and 8 inch centers for full handle clearance
“Solid Brass valve body constructed with metal handles for durability. This roman tub faucet has ICC-ES PMG certification and is compliant with standard: ASME A112.18.1/CSA B125.1-2018, plumbing supply fittings (the same standard as cUPC certification)”
“A drip-free MS ceramic cartridge tested for 600,000 uses paired with a 4-29/32 inch spout reach. If your bathtub is large, we recommend you selecting the 8-3/8 inch spout reach”
Two lever handles for precise control of temperature and flow; brushed nickel finish

The certification is the reason to buy this

ICC-ES PMG. ASME A112.18.1 / CSA B125.1-2018.

That is the North American standard for plumbing supply fittings, and most American codes require fittings listed to it — which is what a cUPC or ICC-ES PMG listing establishes.

A faucet without it may work perfectly for twenty years and still fail an inspection on a permitted job.

Of the seven faucets on this shelf, two publish compliance: this and the WOODBRIDGE. Five publish nothing.

Six hundred thousand uses

On the cartridge, which is the only part of a faucet that wears out and the only reason faucets drip.

LOCALAND matches this at 600,000. The other five listings give no figure.

At two baths a day, six hundred thousand operations is a number with no practical meaning — which is the point. It is a statement about which kind of cartridge went in.

Twelve point one six, with an honest caveat attached

12.16 GPM at 60 PSI fills a 55-gallon tub in about four and a half minutes, against fifteen minutes for the slowest faucet on this shelf.

But a faucet cannot pass more water than the pipe feeding it, and a 1/2 inch supply at ordinary household pressure moves roughly 6 to 8 gallons a minute.

So this figure describes the faucet, not your bathroom. Note that SUMERAIN quotes it with a pressure — as WOODBRIDGE quotes 4.5 GPM at 80 PSI — which is the correct way to state it and something the ryuwanku and LOCALAND listings do not do.

What a 12 GPM faucet guarantees is that the faucet will never be the restriction.

And the sentence that costs SUMERAIN a sale

If your bathtub is large, we recommend you selecting the 8-3/8 inch spout reach.

This faucet reaches 4-29/32 inches, and a Roman tub deck is wide — often six to twelve inches from the faucet hole to the inner wall.

Too short a reach and the water lands on the deck instead of in the bath.

No other maker on this shelf raises it. Measure from the center of your faucet hole to the inside of the tub before ordering. For reference, the WOODBRIDGE publishes seven inches of reach and the Aolemi nine.

What it does not include

No handheld shower. Five of the seven faucets here have one; this and the Pfister do not.

No warranty published, where Pfister gives a limited lifetime and the ryuwanku 202503 gives five years.

And no supply lines stated in the box.

Strengths, and the catches

Strengths

ICC-ES PMG certification and compliance with ASME A112.18.1, which is the plumbing-supply-fittings standard American codes require — five faucets here publish nothing
A cartridge tested for 600,000 uses, matched only by the LOCALAND on this shelf
Tells you its spout reach is 4-29/32 in and to buy the 8-3/8 in version for a large tub, which no other maker here does

Compromises

Twelve point one six gallons a minute is more than most domestic 1/2 in supplies can deliver, so the figure describes the faucet rather than your bathroom
No handheld shower, where five of the seven faucets on this shelf include one
No warranty published, and no supply lines stated as included

Specifications

Center distance	8 IN Centers, on three deck holes of 1-1/4 in diameter — the only fixed center distance published here (the LOCALAND is adjustable, and the Pfister depends on a valve sold separately), and the figure that decides whether it fits the holes you have. 10 × 2.80 × 14.6 in (254 × 71 × 371 mm), 2,232 g.
Mounting	Deck. SUPPLY LINES ARE NOT STATED AS INCLUDED, where the floor-mount faucets here ship theirs. No warranty is published.
Spout reach	4-29/32 in — the SHORTEST published reach on this shelf, and the maker itself recommends its 8-3/8 in version for large tubs.
Shower diverter	NONE — no handheld shower is fitted, one of two faucets here without one. Two metal lever handles, on a drip-free MS ceramic cartridge tested for 600,000 uses.
Flow rate	12.16 GPM at 60 PSI — THE HIGHEST ON THIS SHELF, 2.7 times the lowest, filling a 55-gallon tub in about 4.5 minutes. ICC-ES PMG certified, compliant with ASME A112.18.1 / CSA B125.1-2018, on a certified solid brass valve body.
Finish	Brushed nickel.

The questions we get

Will I actually get 12.16 gallons a minute?

Almost certainly not, and the reason is upstream of the faucet. A faucet cannot pass more water than the pipe feeding it, and a 1/2 inch supply line at ordinary household pressure moves roughly 6 to 8 gallons a minute. Twelve gallons needs generous pipework and good pressure. The figure is the faucet’s capability at 60 PSI, not a promise about your bathroom — which is also why it is quoted with a pressure attached, as the WOODBRIDGE’s 4.5 GPM is quoted at 80 PSI. Still, a faucet that can pass 12 GPM will never be the restriction, and that is worth something.

Why does ASME A112.18.1 matter more than most certifications here?

Because it is the one an inspector looks for. ASME A112.18.1 / CSA B125.1 is the North American standard for plumbing supply fittings, and most American plumbing codes require fittings certified to it — which is what cUPC and ICC-ES PMG listings establish. An uncertified faucet may work perfectly and still fail an inspection on a permitted job. Of the seven faucets on this shelf, only this one and the WOODBRIDGE publish compliance with it; the other five publish nothing.

How serious is a 4-29/32 inch spout reach?

It decides whether water lands in the tub or on the rim, and SUMERAIN is the only maker here honest enough to raise it. A Roman tub deck is wide — often six to twelve inches from the faucet holes to the inside edge — and a five-inch reach can leave the stream falling onto the deck. The bullet says plainly: "If your bathtub is large, we recommend you selecting the 8-3/8 inch spout reach." Measure from the center of the faucet hole to the inner tub wall before ordering. For comparison, the WOODBRIDGE publishes 7 inches of reach and the Aolemi 9.
