Bathtub spouts direct water downward into a tub.

Tub spouts are available in three types that each require a different installation method. The types are dependent on the plumbing in the bathroom wall and include iron pipe, slip-on and copper pipe. Delta has many different styles and finishes available in all three types of tub spouts to match existing fixtures in the bathroom.


Iron Pipe Installation

Step 1

Place a large flat screwdriver in the opening in the bottom of the old tub spout. Turn the spout counterclockwise to unscrew it from the iron pipe.

Step 2

Clean any old Teflon tape off the threads of the pipe nipple. Apply three revolutions of Teflon tape in a clockwise direction to the pipe threads. Press the Teflon tape into the threads firmly.


Step 3

Place the new Delta tub spout on the pipe threads and turn clockwise to attach. Place a towel over the spout and continue tightening with adjustable pliers so that the spout is tight to the wall and the opening faces downward into the tub.

Slip On Installation

Step 1

Place a hex wrench into the opening underneath the tub spout. Turn the hex wrench counterclockwise to loosen and remove the screw.


Step 2

Pull the old tub spout out away from the tub wall with both hands and medium force. Dispose of the old tub spout.

Step 3

Place the Delta tub spout onto the copper pipe so that it touches the bathtub wall. Insert the new hex screw into the opening in the bottom of the spout.


Step 4

Place a hex wrench on the hex screw and turn clockwise to tighten it fully.

Copper Pipe Installation

Step 1

Place a large screwdriver in the opening of the spout. Turn counterclockwise to unscrew it and remove the old spout. Dispose of the old spout.


Step 2

Pull the O-ring off the copper pipe with adjustable pliers and set aside.

Step 3

Solder the tub spout adapter in the spout kit onto the copper tube on the pipe protruding from the wall.

Step 4

Cut the excess tube off directly in front of the O-ring groove in the tube using a hacksaw.


Step 5

Place the new O-ring from the spout kit in the O-ring groove by sliding it on the end of the brass adapter from the spout kit.

Step 6

Screw the Delta tub spout onto the threads of the pipe near the wall. Turn the spout clockwise until it is hand tight and rests against the wall with the opening downward into the tub.


When purchasing a new Delta spout it is best to remove the old one first to examine the plumbing connections and select a style that uses the same installation procedure.

Apply Teflon tape in a clockwise direction so that the spout turns in the same direction for installation.

Do not allow solder to touch the O-ring in the copper pipe installation. It will harden the O-ring so that the faucet will not seal properly and result in a dripping faucet.


Do not over-tighten a tub spout in any installation method as it can crack the wall or tub with excessive force.
