Installation
Watch the Installation
See how to install your RAINLY shower head in just a few simple steps.
- Step 1
Remove your existing shower head
Unscrew your current handheld shower head or hose by hand. If it is tight, a cloth gives you extra grip.
- Step 2
Connect the RAINLY hose
Attach the stainless steel hose to your shower outlet and hand-tighten. Included with the Complete Kit; your existing standard hose also works.
- Step 3
Install the RAINLY shower head
Screw the RAINLY head onto the hose. Hand-tight is enough — no tools or plumbing tape required for most setups.
- Step 4
Check the filter
Unscrew the handle base and confirm the filter cartridge is seated correctly, then close it back up.
- Step 5
Test your spray modes
Run the water and cycle through Spray, Rain, Mixed and Rinse. Try the STOP button to pause the flow.
Filter care
Replacing Your Filter
Replace the cartridge about every 2 months. Replacement timing depends on your incoming water quality and how often you shower. Rinse the spray plate occasionally to keep the nozzles clear.
