Collection: Riobel Arca

• Pull-down faucets — C-spout and U-spout, single spray and dual spray, at 1.8 GPM.
• Touchless — C-spout dual spray at 1.5 GPM, for hands-free operation at the sink.
• Bar and food prep — C-spout single spray, 1.8 GPM, for a secondary sink.
• Filtered water faucet — 1.2 GPM, a dedicated tap beside the main one.
• Pot filler — 5.5 GPM, wall-mounted over the range.

• Lavatory faucets — single-hole with push drain, tall vessel, widespread in C-spout and U-spout, and a wall-mount 360° trim.
• Shower kits — trim-only (323, 1244, 1345), complete with rough-in (4744), a 3-way coaxial thermostatic/pressure-balance system (2745), and a Type P pressure-balance shower with the valve included.
• Tub fillers — floor-mount thermostatic, wall-mount at 5 GPM, 3-hole deck-mount in thermostatic (TAA10) and pressure-balance (TAA16), plus a wall-mount tub spout.

Arca is one of the ten Riobel collections with its own accessory range — robe hook (AA0), toilet paper holder (AA3), 24" towel bar (AA5) and towel ring (AA7). That means a bathroom can be finished in one design language rather than approximated.

Arca goes one step further than that. EMTEK makes cabinet hardware in the Arca design — an 18" appliance pull, a 6" cabinet pull and a 1.25" round knob — and EMTEK is part of the same House of Rohl group, so the finishes are coordinated. A kitchen can run the same design from the faucet to the drawer pulls.

• The 1/2" pressure balance trim takes an R51 — one shower head.
• The up-to-3-functions trim takes an R23.
• The up-to-5-functions trim takes an R45.
• Kits sold “with rough-in valve” already include the correct body.

Count your outlets before ordering — the valve is behind the tile and cannot be changed later. See Riobel Shower Valves & Rough-Ins.

Arca is offered in Chrome (C), Stainless Steel (SS), Polished Nickel (PN), Black (BK) and Satin Brass (US4), the finish new for 2026. The EMTEK Arca hardware is finish-matched to the same range.

Does Arca cover both kitchen and bathroom?
Yes. Arca and Authentica are the two Riobel collections that do, which is why they suit a whole-house specification.

Can I get cabinet hardware to match an Arca faucet?
Yes. EMTEK makes Arca-design cabinet pulls, an appliance pull and a round knob. EMTEK is a House of Rohl brand, so the finishes are coordinated with the faucet.

What is the difference between the C-spout and U-spout?
The shape of the arc. The C-spout curves continuously; the U-spout rises and turns more squarely. Function is the same — pick by what suits the sink and the window behind it.

Which Arca kitchen faucet has the best reach?
The pull-down models all have a retractable spray head. The bar/prep faucet is smaller and intended for a secondary sink, not the main one.
