Can I fix the leak without changing the fixture?

Single handled shower valve? If so you can rebuild or replace the cartridge for under $20. If it were a Moen valve the fix would be free.

Delta is a super easy valve to repair...

Like Balleneger asked... single or multiple handles?

Check out these pics. For info. That may help you to repair your unit.

Common to all these are the SEATS AND SPRINGS (#2 in left pic. And #4 in pic. On right)... see last picture. These are available at all home improvement stores.

Let us know if need more info...

Please respond to Bob.

If you give us the model number will be great.
