Is your old, calcified shower head spraying water everywhere but on you? A new shower is a quick way to brighten up your bathroom and, most importantly, improve your showering experience. However, many people wonder whether shower installation requires a professional or if it can be done DIY.
The answer is clear: replacing a hand shower and hose can usually be done perfectly well by yourself. At Showerguy, we've seen countless installations and can assure you that the job will be successful, provided you prepare properly. With these instructions, we'll guide you through the entire process step by step.
Before you begin: The right tools and preparation
Good preparation ensures a smooth installation. When everything you need is readily available, the job itself will be quick and stress-free. Gather the following tools and supplies:
-
Adjustable wrench or pipe wrench: Needed to remove the old shower hose and attach the new one. A quality tool won't slip and will make the job easier.
-
Teflon tape (PTFE thread seal tape): Thin tape for sealing threads and preventing leaks. This is an absolute must-have.
-
Soft cloth or rag: A professional trick: protect new, shiny chrome parts from scratches by placing a cloth between the nut and the tool when tightening.
-
Bucket and old towel: There will always be some water left in the hose. Place a bucket under the faucet during the removal phase to avoid having to dry the floor.
Safely removing the old shower
The old shower must be removed before installing the new one. Proceed calmly to avoid water damage.
-
Turn off the water supply. This is the most important step. Locate the shut-off valve for the shower faucet, which is usually connected to the faucet or in the vanity cabinet. If there is no separate shut-off, close the main water valve for the apartment. Ensure the water is off by turning on the faucet – no water should come out.
-
Drain the pipes. With the water off, open the shower faucet and let any remaining water drain from the hose and pipes into the bucket.
-
Remove the old shower hose. Place the bucket under the faucet. Use an adjustable wrench or pliers to grip the hose nut at the base of the faucet and turn counter-clockwise. If the nut is tight, don't use brute force, but gently wiggle it back and forth.
-
Remove the old shower head. The shower head is usually attached to the hose only hand-tight. If limescale has jammed it, use pliers and remember to protect the surface with a cloth.
-
Clean the faucet threads. Once the hose is off, thoroughly clean the faucet threads of any old Teflon tape, limescale, and dirt. Clean threads ensure a tight connection.
New shower installation: Step-by-step
Now we get to the rewarding part. Work systematically to achieve a neat and watertight result.
Step 1: Seal the threads with Teflon tape
Wrap Teflon tape around the threads of the faucet outlet. Important tip: wrap the tape clockwise, i.e., in the same direction you will tighten the nut. This prevents the tape from rolling off when attaching the hose. 3-5 turns are sufficient. Do not use tape on connections with a rubber gasket, such as between the hose and the shower head.
Step 2: Attach the new shower hose to the faucet
Check that the gasket is in place inside the new hose nut. Hand-tighten the nut onto the faucet threads as far as it goes. Place a protective cloth between the nut and the wrench and tighten another quarter or half turn. Remember our most important instruction: do not overtighten! Overtightening will crush the gasket and cause a leak.
Step 3: Attach the new shower head to the hose
The other end of the hose has a conical nut that attaches to the shower head. This connection also has a rubber gasket, so Teflon tape is not needed. Hand-tighten the shower head to the hose. Finger-tight is sufficient.
Step 4: Special considerations: Filters and aroma cartridges
If you have chosen a modern shower, such as the popular Aroma Sense shower from our selection, now is the time to install its accessories. Unscrew the shower head handle and insert the microfiber filter and any vitamin C aroma gel cartridge according to the instructions. This completes the luxurious and skin-friendly showering experience.
Testing and finishing: Ensure nothing leaks
The installation is only complete once the tightness of the connections has been tested.
Open the water supply slowly and allow the system to pressurize calmly. At the same time, observe the connection between the faucet and the hose. When the water is fully on, feel with your fingertip to ensure that neither connection – at the base of the faucet or at the shower head – is dripping water.
If you notice a small leak, turn off the water and tighten the connection slightly more, about 1/8 of a turn. If this does not help, disassemble the connection, check the position of the gasket, and ensure that there is enough Teflon tape on the faucet threads.
Once everything is dry and tight, you have succeeded. Good job!
Common mistakes in shower installation (and how to avoid them)
In our experience, three pitfalls often recur. Avoid them with these tips.
-
Overtightening connections. By far the most common mistake. Many believe that tighter is more watertight, but the truth is the opposite. Too much force crushes the rubber gasket or damages the threads, leading to leaks. Finger-tightening and a small additional tightening with a wrench are sufficient.
-
Scratching surfaces. It's a shame to scratch a new, shiny shower right during installation. Always use a soft cloth between the tool and the nut to keep your shower's finish pristine.
-
Leaving old gaskets and tape in place. Don't cut corners here. Always clean any remnants of old Teflon tape and dirt from the faucet threads. A clean surface ensures the best seal.
Installing a new shower yourself is not only cost-effective but also rewarding. Every time you step into a refreshing shower, you'll remember your success. When you want to ensure the best results with high-quality and water-saving products, explore Showerguy.fi's extensive shower selection.
Frequently Asked Questions
How often should a shower head be replaced?
A shower head should be replaced every 3–5 years, depending on water hardness and usage. Over time, limescale clogs nozzles and weakens water pressure. It's also a good opportunity to upgrade to new, water-saving and skin-friendly technology, such as that offered by Aroma Sense showers.
What do I do if the water pressure is weak after installation?
If the pressure is weak immediately after installation, the cause is almost always sediment detached from the piping that has clogged the hose's filter screen. Unscrew the shower hose from the faucet and check the small sieve inside the nut. Rinse it clean, reattach the hose, and the pressure will return to normal.
Can I install any shower head on any hose?
Yes, almost always. Shower hose and head threads are standardized in Europe (G 1/2 inch), so parts from different brands are compatible. You can therefore safely upgrade just the shower head and use the old hose or vice versa. Only very old or special design systems may have exceptions.
Is Teflon tape always mandatory?
Not always. Teflon tape is only used on metal threaded connections where there is no rubber gasket – typically between the faucet and the shower hose. However, the connection between the shower hose and the hand shower should not be taped, as the seal relies on the rubber gasket in the nut. Tape can even prevent a tight connection from forming.
How do I clean a new shower head without scratching it?
Regular cleaning with mild soapy water and a soft cloth is sufficient. Never use abrasive sponges or strong chemicals, which can damage surfaces. For effective and safe limescale removal, soak the shower head in a water-vinegar solution (1:1 ratio) for a few hours. Rinse thoroughly afterwards.
