Tub Supply Lines Buying Guide


Supply lines are the water pipes that go from the floor rough-in to the claw foot tub faucet. They need to be chosen to fit both the proper faucet configuration and rough-in through your floor. Your supply lines can be cut on site by your plumber. We strongly recommend that your tub and hardware be on site prior to rough-in. If you have any questions or are purchasing tub supply lines for your new or antique tub, you can call us toll free at 877-868-1369 to discuss with a customer service representative.

The lines we sell are for exposed installations and come in four general styles: straight, single offset, double offset, and freestanding.

Straight
Straight supply lines (also called Deck-mounted supply lines) are used with deck-mounted faucets. Straight supply lines are roughed-in on the same centers as the faucet drillings on the rim of the claw foot tub, most commonly 7”.
Single-Offset
Single-offset lines have only one bend at the top of the lines. They are used with our 3 3/8” tub wall-mounted regular and handshower faucets as well as most of our tub wall-mounted shower enclosures. Single-offset supply lines go through the floor at 3-3/8” on center.

You have your choice of supply lines with or without shut off valves. Rough-in will vary depending on which option you choose.

Double-Offset
Double-offset lines have two bends at the top of the supply lines. They are used with our 3 3/8” tub wall-mounted regular and handshower faucets as well as most of our tub wall-mounted shower enclosures. Double-offset supply lines go through the floor at 8” on center.

You have your choice of supply lines with or without shut off valves. Rough-in will vary depending on which option you choose.

Freestanding
Freestanding supply lines are used when you tub has no faucet drillings. They are made of thicker brass to support the weight of the claw foot tub faucet and are roughed-in according to the centers of the faucet.

Extensions are offered if additional height is needed.
