Deck Mount Tub Fillers

Deck mount tub fillers install directly onto the rim of the bathtub or the deck built around it, so the spout and handles sit beside the tub rather than on the wall or rising from the floor. They are the usual choice for drop-in and undermount tubs, and for tubs set into a tiled surround where the supply lines run up through the deck. If you have been searching for a deck mounted tub faucet, this is the category to shop. Brands here include Rubinet, TOTO, Perrin & Rowe, Riobel, ROHL, Cheviot, Aquabrass and AquaDesign, with examples such as the Edge 4-piece Deck-mount Tub Filler With Hand Shower, the Edwardian 4-Hole Deck-mount Tub Filler and the Rubinet Genesis Deck Mount Tub Filler Spout.

Finish options offered range from Chrome, Polished Nickel and Brushed Nickel to Matte Black, Unlacquered Brass, English Gold and Tuscan Brass, which makes it easier to match a vanity faucet or shower trim already in the room. Before you order, confirm how your tub deck is drilled or will be drilled, decide whether you want a hand shower at the tub, and check whether the listing is a complete filler or a trim that pairs with a separately purchased rough-in valve.

What to check before you buy

• Count and measure the deck holes. Match the number of holes in your tub rim or deck to the configuration of the filler, and measure the spacing between hole centres. If the deck is not drilled yet, pick the filler first and drill to its template.
• Check deck thickness and clearance below. Deck mount fillers thread through the deck and are tightened from underneath, so confirm your deck thickness is within the maximum the fixture allows. Make sure there is access below for the valves, supply connections and any hand shower hose.
• Confirm spout reach to the tub. The spout needs to clear the rim and deliver water comfortably into the tub without splashing the deck. Measure from where the spout will sit to the inside edge of the tub before choosing a spout length and style.
• Trim versus complete filler. Some listings are trim only and need a matching rough-in valve or union set that is sold separately. Read the product details carefully so you order everything the installer needs on the first visit.
• Match the finish across the room. Finishes such as Polished Chrome, Satin Nickel and Matte Black read differently in daylight than under vanity lighting. Compare the tub filler finish against your sink faucet and shower trim before you commit.

Frequently asked questions

What is a deck mount tub filler?

A deck mount tub filler is a bathtub faucet that mounts on the flat rim of the tub or on the surrounding deck, with the plumbing coming up from below. It is different from a wall mount filler, which comes out of the wall, and a floor mount filler, which stands on its own column beside a freestanding tub.

Can I use a deck mount tub filler with a freestanding tub?

Only if the tub has a wide, flat rim that can be drilled, or if you build a deck or ledge beside it to carry the fixture. Otherwise a floor mount or wall mount filler is the usual route for a freestanding tub.

Do I need a separate valve for a deck mount tub filler?

It depends on the product. Some are supplied as complete fillers, while others are trim kits that are finished with a rough-in valve or unions bought separately, so check the listing and ask your plumber what they prefer to work with.
