Re-install the faucet trim, including the escutcheon plate and the handle, onto the stem of the newly installed cartridge. Once everything is reassembled, slowly turn the main water supply back on. Test the faucet by turning the handle to check for proper hot and cold water flow. Finally, turn the water off and carefully inspect for any leaks around the handle or from the tub spout.
Goal: Verify the repair and check for leaks
- Turn the water supply on slowly to allow air to escape from the pipes and to catch any major leaks before full pressure is applied.

FAQs
What is the most crucial first step before beginning the Delta shower trim installation, and what happens if I skip it?
You absolutely must shut off the main water supply to your shower, or ideally your entire house, before starting. Skipping this step will result in an immediate and significant flood once you begin removing the old trim, causing potential water damage and making the job impossible to complete safely.
Besides a multi-screwdriver, are there any other tools or materials I might unexpectedly need for this Delta shower trim kit installation?
While a multi-screwdriver is primary, a utility knife is very helpful for scoring old caulk around the escutcheon plate. You might also want a rag and cleaner to prepare the surface, and a tube of silicone caulk to create a watertight seal around the new escutcheon plate after installation.
The project is listed as 'beginner' and '2 hours.' What factors could make this Delta trim installation more difficult or take longer than expected for a DIY novice?
While generally straightforward, unforeseen issues like stripped screws on the old trim, excessive corrosion preventing removal, or an unfamiliar internal valve setup can increase difficulty and time. Ensuring you have the correct Delta trim kit model for your existing Delta valve is also critical, as incompatible parts will cause delays.
My current shower valve isn't Delta, or it's a very old Delta model. Can I still use a new Delta shower trim kit?
No, Delta shower trim kits are designed to fit specific Delta universal rough-in valves or proprietary older Delta valve bodies. If your existing valve is from another brand, or a pre-1990s Delta valve that isn't compatible, you will likely need to replace the entire valve behind the wall, which is a much more complex plumbing project.
