House of Rohl Authentica™ 3-Hole Deck Mount Tub Filler Trim TAU10

The Wait You Should Not Have to Endure

Filling a bathtub should not feel like a chore. You turn on the water. You wait. You check the temperature. You wait more. The water creeps up the side of the tub. Five minutes pass. Ten minutes pass. You start to wonder if the tub will ever fill. By the time it does, the water has cooled. The moment has passed. The House of Rohl Authentica TAU10 deck mount tub filler trim eliminates the wait. The 8.7 GPM flow rate fills the tub in a fraction of the time. The water stays hot because it does not sit in the pipes. You step in while the water is still steaming. You sink into the warmth. The wait is over. For homeowners in Toronto and Vancouver who value their time, this matters. For anyone who has ever abandoned a bath because the tub took too long to fill, the Authentica changes the experience.

The Flow Rate That Makes the Difference

The Authentica delivers 8.7 gallons per minute at 60 PSI. That is 33 litres per minute. A standard tub filler delivers 4 to 5 GPM. The Authentica delivers nearly double. The difference is noticeable. A standard tub fills in 15 to 20 minutes. The Authentica fills it in 8 to 10 minutes. You save time every single bath. Over a year, those minutes add up. For homeowners in Calgary and Edmonton who enjoy a nightly soak, this matters. For anyone with a large freestanding tub, the Authentica delivers the flow needed to fill it efficiently.

The Integrated Diverter and Handshower

The Authentica includes an integrated diverter. The diverter switches water between the tub filler and the handshower. You do not need a separate diverter component. The diverter is built into the trim. The operation is smooth. The handshower delivers 1.8 GPM at 60 PSI. The handshower is single function. It is designed for rinsing. Rinse the tub after use. Rinse your hair. Rinse the walls. The handshower features anti-calcium construction. The nozzles resist mineral buildup. When deposits form, you wipe them away. The handshower stays clean. The maintenance is minimal.

The Solid Brass Construction That Lasts

The Authentica is made from solid brass. This is not a plastic body with a metal coating. It is solid brass from the inside out. Brass resists corrosion from water exposure. It handles temperature changes without weakening. It maintains its structural integrity for decades. The weight feels substantial in your hand. The finish resists tarnishing. The trim looks as good in year ten as it did on installation day. For bathrooms in Halifax and St. John’s where humidity is constant, the brass holds up. For homes in Winnipeg and Regina where temperature swings stress materials, the brass stays solid.

The Black Finish That Makes a Statement

The Authentica TAU10 is available in Black. Black is not a standard finish. It is a statement. It absorbs light. It creates depth. It contrasts against white tubs and light tile. It anchors the bathroom with a strong visual presence. The Black finish resists water spots and fingerprints better than polished finishes. It maintains its appearance with minimal care. For homeowners in Ottawa and Montreal who want a bold look, the Black finish delivers. The Authentica is also available in Brushed Nickel, Chrome, and Polished Nickel for those who prefer a different aesthetic.

The Three-Hole Deck Mount Configuration

The Authentica uses a three-hole deck mount configuration. This is a traditional layout. The spout sits in the center hole. The handles sit on the sides. The handshower mounts in the third hole. The spacing is standard. The installation is straightforward. The deck mount design is compatible with freestanding bathtubs that have adequate deck space. It is also compatible with undermount and drop-in bathtubs. The controls and water delivery components sit at the tub deck. The layout is practical. The design is intentional. For homeowners in Mississauga and Brampton who have a drop-in tub, the Authentica fits. For anyone with a freestanding tub that has a deck, the Authentica works.

What Installation Requires

The Authentica trim requires a compatible rough valve. The rough valve is sold separately. The specified options are House of Rohl RHTB, RHTB-SPEX, or RHTB-EX. The trim uses a 1/2-inch male NPT inlet connection. All hardware required for installation is included with the trim. A licensed plumber familiar with Canadian code should handle the installation. The rough valve must be installed before the trim. Confirm compatibility before ordering.

To complete the tub setup, pair this trim with a Deck Mount Tub Filler rough valve for a complete installation. For the shower area, browse our Tub Fillers category for coordinating options.
