How To: Replace a Crusty Old Tub Spout

Replacing a tub spout is a straightforward project whose necessity arrives sooner or later in the life of most bathrooms.

A tub spout does two things: It provides a decorative cover for the pipe stub delivering water to the bathtub, and it directs the water away from the wall where it could cause damage.

Our spout was more or less failing at both functions. It was severely pitted and judging from the amount of caulk around its base, the spout had a long history of leaking.

For ease of installation and a gap-free fit at the wall, we chose a slip-connection replacement spout. Several types and styles of spouts are available; be sure to select one that complements the design of your shower system.

For example, if you control the shower with a diverter knob, buy a spout with a diverter. If, on the other hand, the diverter is not part of your shower control, buy a spout without a diverter.

Bear in mind that if your replacement spout is one that threads into place, picking up some plumber’s tape is a good idea, since wrapping the old threads will ensure a watertight joint.

MATERIALS:
- Large screwdriver or wood hammer
- Razor scraper with new blade
- Mini tubing cutter
- Steel wool
- Plumbing grease
- Slip-connection tub spout (with or without diverter)
