Fitting a shower filter is a hand-tight job. No plumber, no tools, no drilling. If you can screw the cap back on a bottle you can do this.
Below is the full sequence with the details that actually matter, including the two things people get wrong and the one part that takes longer than two minutes despite what the headline says.
A note on that headline, since we would rather be straight with you. The filter itself goes on in under two minutes. The adhesive wall bracket needs 24 hours to cure before you hang anything on it. You can shower the same day using the existing bracket or holder, but do not load the new one until tomorrow. Every brand quotes the fast number and stays quiet about the slow one.
Before you start: check compatibility

Thread size. UK mixer showers use a universal G1/2 thread, sometimes written as 1/2 inch BSP. This is what the hose screws onto at both ends. Almost every standard UK shower uses it. If your existing hose unscrews by hand from the wall outlet, you are fine.
Shower type. This is the important one. VYLLO is designed for mixer showers fed from a boiler, combi or tank. It is not suitable for some water heaters without flow control, including certain manual-switch start heaters. If you have an instantaneous electric shower unit, the kind with a box on the wall and a pull cord, check before ordering rather than after.
Water pressure. Adding filtration stages means water is passing through media, so very low-pressure gravity-fed systems will feel the difference more than a pressurised system will. If your current shower is already weak, filtration will not improve it.
What is in the box
Everything you need is in the kit, so there is no trip to a hardware shop halfway through:
- Handheld shower filter with three spray modes and a separate pause button
- Inline Lavender Vitamin C cartridge
- Stainless steel hose
- Matte black wall bracket with adhesive pad
- PTFE tape
- Three PP cotton filters, one already fitted inside the handset and two spare
- Welcome card and installation guide
Lay it all out on a towel before you begin. Small rubber washers are the one thing people lose down a plughole.
Step 1: Remove the old shower head and hose
Unscrew the hose from the wall outlet by hand, turning anticlockwise. Then unscrew the old handset from the other end of the hose.
If either end is stiff with limescale, grip it with a cloth for purchase rather than pliers, which mark the chrome. A stubborn joint usually gives after a few minutes with a cloth soaked in warm water wrapped around it.
Keep the old parts. Put them in a box, especially if you rent. You will want them on move-out day.
Step 2: Check the washers
Look inside both ends of the new stainless steel hose. Each should contain a small rubber washer sitting flat.
This is the step everybody skips and it is the cause of most leaks people blame on the product. If a washer is missing, crooked or doubled up, the joint will weep. Seat it flat before you screw anything together.
Step 3: Wrap the PTFE tape
Take the wall outlet thread and wrap the PTFE tape around it two or three times, in the same direction the fitting will screw on, which is clockwise as you face the thread end. Wrapping against the direction makes the tape bunch up and unravel as you tighten.
Pull it firm enough that it sits into the thread grooves rather than sitting loose on top. Two or three wraps is plenty. More is not better and a thick wad of tape will stop the joint seating properly.
PTFE tape is only needed on the wall outlet thread. The hose-to-handset and hose-to-cartridge joints seal on their rubber washers.
Step 4: Fit the hose to the wall outlet
Screw the hose onto the taped wall outlet by hand, clockwise, until it is firm.
Hand-tight is the correct tightness. These are washer-sealed joints, not compression fittings, and overtightening crushes the washer and causes the leak you were trying to avoid. If it is snug and does not turn easily, stop.
Step 5: Fit the inline Vitamin C cartridge
The cartridge goes between the hose and the handset, not between the wall and the hose.
Check the cartridge for a flow direction arrow or an inlet and outlet marking. Water should enter from the hose side. Fitting it backwards will not break anything, but the gel will not dissolve at the intended rate.
Screw the hose onto the inlet end, hand-tight, washer seated flat.
Step 6: Fit the handset
Screw the handset onto the outlet end of the cartridge, hand-tight. Check that washer too.
The PP cotton filter is already installed inside the handset, so there is nothing to fit at this stage. The two spares in the box are for later.
Step 7: Run the water and check for leaks
Turn the shower on and let it run for 30 to 60 seconds. You may see slight discolouration or a few fine particles at first as the media settles. That is normal on a new filter and clears quickly.
Now check every joint with a dry finger:
- Wall outlet to hose
- Hose to cartridge
- Cartridge to handset
Any weeping is almost always a washer that is not seated or a joint that needs another quarter turn. Undo, check the washer, redo. It is very rarely the PTFE tape unless you skipped it.
Cycle through the three spray modes and press the pause button to check it holds. The pause is the feature people forget they have, and it is genuinely useful when conditioner is in your hair and you would rather not stand under running water.
Step 8: Mount the wall bracket
This is the slow part.
- Choose the position. Hold the handset where you want it and mark the spot mentally before committing, since adhesive gets one good attempt.
- Clean the surface with isopropyl alcohol, not bathroom spray. Cleaning product residue is the single most common reason adhesive brackets fall off later.
- Let it dry completely.
- Peel the backing, press the bracket firmly against the tile and hold for 30 seconds.
- Leave it 24 hours before hanging the handset on it. Use your old bracket or rest the handset in the bath until then.
Surface matters. Adhesive needs smooth, non-porous surfaces. Gloss tile, glass and acrylic panels are ideal. Textured tile, grout lines and painted plaster are not, and the bracket will let go at three in the morning.
Troubleshooting
A joint is dripping. Washer, nine times out of ten. Undo the joint, check the washer is present, flat and single, and redo hand-tight.
Water pressure feels lower. Check nothing is cross-threaded and that the PTFE tape has not bunched into the opening. If the setup is correct and pressure is still low, your system may be gravity-fed and running near its limit.
The bracket will not stick. Surface or residue. Re-clean with isopropyl alcohol, or move to a smoother spot. On textured tile, adhesive will not hold reliably and the honest answer is to use the existing fixing.
Water looks slightly cloudy at first. Normal on a new filter. Run it for a minute.
The cartridge is dissolving faster than expected. Usually flow rate or household usage rather than a fault. The inline cartridge lasts approximately three months depending on water quality and how heavily the shower is used.
After installation
The PP cotton filter inside the handset is changed when it looks visibly discoloured. You have two spares in the box. How fast that happens depends on the sediment in your local supply, which varies a lot across the UK, so we would rather you look at the filter than follow a number we made up.
The inline Vitamin C cartridge is the part you replace most often, roughly every three months. The gel is visible through the casing, so you can watch it go rather than guess.
Both stages use media designed to help reduce chlorine in the water passing through, and if you want the detail on how that works we covered it properly in our guide to Vitamin C shower filters.

Frequently asked questions
How do you install a shower filter? Unscrew the old hose and handset, wrap PTFE tape around the wall outlet thread, screw on the new hose hand-tight, fit the inline cartridge between hose and handset, then attach the handset. Run the water and check each joint for leaks. It takes under two minutes and needs no tools.
Do I need a plumber to fit a shower filter? No. Standard UK mixer showers use a universal G1/2 thread and every connection is hand-tight, so no plumbing work or tools are required.
Which way do you wrap PTFE tape? Clockwise as you face the end of the thread, which is the same direction the fitting screws on. Two or three wraps is enough. Wrapping the other way causes the tape to bunch and unravel as you tighten.
Why is my shower filter leaking? Almost always a rubber washer that is missing, crooked or doubled up inside the hose connector. Undo the joint, seat the washer flat and refit hand-tight. Overtightening can cause leaks rather than prevent them.
How long does the adhesive shower bracket take to set? Leave it 24 hours before hanging the handset on it. Clean the surface with isopropyl alcohol first and press firmly for 30 seconds when fitting.
Can I fit a shower filter to an electric shower? Check compatibility first. VYLLO is not suitable for some water heaters without flow control, including certain manual-switch start heaters. It is designed for mixer showers fed from a boiler, combi or tank.
