How to Install a Two-Handle Shower Valve · Step 7 of 7
In this video
Turn on the shower to test the new installation. Check all functions of the handheld shower head. Once confirmed everything is working correctly and there are no leaks, apply a bead of silicone caulk around the top and sides of the escutcheon plate where it meets the tile wall. Do not caulk the bottom edge to allow any moisture that gets behind the plate to drain out. Use a wet sponge to smooth the caulk bead for a clean finish.
Goal: Verify proper function and waterproof the installation
- Leaving the bottom of the escutcheon un-caulked is a professional practice that prevents water from getting trapped in the wall.

FAQs
What are the most critical skills and tools required for this project, especially for a beginner?
The most critical skill is copper pipe soldering, as the new valve needs to be securely joined. Essential tools include a pipe cutter (like the AUTOCUT 1/2 in. Copper Pipe Tubing Cutter), a soldering torch kit, flux, solder, and safety glasses (HDX Indoor Safety Glasses). Practice soldering on scrap pipe if you're new to it.
How can I ensure I don't cause water damage or other issues during installation?
Always shut off the main water supply to your house before starting any plumbing work. After soldering, pressurize the system and carefully inspect all new connections for leaks before closing up the wall. Use Kleenex Paper Towels to dab around joints and confirm they are completely dry.
What's a realistic timeframe and difficulty level I should expect for this shower valve replacement?
This project is rated intermediate due to the necessary soldering and gaining access to the plumbing within the wall. For an experienced DIYer, it might take 4-6 hours, but beginners should budget a full day (8+ hours) to account for learning, careful work, and potential troubleshooting.
Are there alternatives to soldering the new shower valve if I'm not comfortable with a torch?
Yes, you can use push-to-connect (e.g., SharkBite) or PEX crimp fittings as alternatives to soldering. These methods require different tools like a PEX crimper or just the specific fittings themselves. While often quicker, they can be more expensive than traditional copper soldering and may result in a bulkier installation.
