What Is a Fast-Fill Faucet on a Walk-In Tub?
Updated September 2026
A fast-fill faucet on an Ella walk-in tub is one of Ella's deck-mounted faucet sets built to fill the tub as quickly as your home's plumbing allows: the 2-piece single-lever set, designed for 16 GPM at 60 PSI, and the 5-piece set with separate hot and cold levers, designed for 18 GPM. Owners also call it the Ella Fast-Fill, the deck faucet or the tub filler, and both sets come with a pull-out hand shower and two 3/4 inch by 5 foot braided supply lines.
How It Works
On the 2-piece set, lift the lever for on, move it left for hot and right for cold, and press the diverter button under the spout to send water to the hand shower. The spout is solid brass in chrome with a high-flow cartridge. On the 5-piece set, the red handle is hot, the blue handle is cold, and the middle lever is the diverter: turn it toward OFF and push the faucet lever down for the hand shower. The hand shower on both sets has 5 flow settings, is limited to 1.9 GPM, and rides on a 5 foot braided hose with a back-flow prevention valve. Our 2-piece vs 5-piece article shows the layout of each set, and the 2-piece set is certified to CSA B125.1, ASME A112.18.1, ICC 117.1, ANSI/NSF 61/9 and IAPMO UPC with an ADA lever.
Which Ella Models Have It
Most Ella walk-in tubs ship with a fast-fill set in the style listed for the model. The Standard and Standard60 come with the 5-piece set, while the Zen and Zen60 and the Flow come with the 2-piece single-lever set; see the Standard and Standard60, Zen and Zen60 and Flow profiles. The LayDown72 is faucet-ready and can take either set as an option, and the LayDown60 has no deck faucet. On your paperwork, the code 5P-FFF is the 5-piece set, and a finish suffix such as BN means brushed nickel.
What to Know as an Owner
- In real homes, fill time runs 7 to 15 minutes depending on tub size and your water supply. The GPM figures assume 60 PSI and ideal plumbing. Our faucet expectations article explains what affects it.
- Shut-off valves are not included, so plan easily accessible ones near the tub. See water supply lines and shutoff valves.
- A dripping or stiff 2-piece faucet usually needs a fresh cartridge; the cartridge replacement steps are simple.
- Hoses and handsets are matched to your set, and the 5-piece hose does not fit the 2-piece faucet.
- For a ticket, have your model, serial number, a photo of the faucet and a short description ready at ellasbubbles.com/support so the team can match the exact part.
