How to Replace the Shower Hose: The Complete Guide in 5 Steps

A shower hose that leaks at each end, twists into loops or lets water through the sheath is one of the simplest replacements in plumbing. Five minutes are enough with the right moves, and the cost is minimal (between 8 and 20 euros depending on the length and finish). This guide details how to replace the shower hose without a leak, choosing the right model and checking every gasket.

The equipment you need

• The new shower hose, in 1.50 m or 2 m depending on your setup
• A pair of water pump pliers or an adjustable wrench
• PTFE (Teflon) tape or a tube of jointing compound
• A dry cloth and a bucket to catch the residual water
• A spare O-ring in case of crushing

Turning off the water before starting

Contrary to popular belief, it is not always essential to turn off the mains water: it is enough to close the mixer valve and run the cold water to bleed the pressure in the hose. If your installation has a shut-off valve dedicated to the bathroom, close it to be safe. Check that no water comes out of the shower head before unscrewing.

The signs that announce a replacement

• Water seeps along the sheath, a sign of internal wear of the tube
• The hose twists systematically and blocks the rotation of the hand shower
• Limescale stains accumulate on the nuts, which become hard to unscrew
• The hand shower falls or changes angle on its own, a sign that the anti-twist spring has given up

Removing the old hose

1. Hold the fitting of the hand shower with one hand and unscrew the hose nut with the pliers.
2. Do the same at the bottom, on the mixer side or the shower column side.
3. Catch the residual water in the bucket.
4. Inspect the threads and gaskets: a crushed gasket often explains the leak.
5. Keep the old hose as a length template.

Choosing the right hose

Shower hoses exist in several lengths (1.25 m, 1.50 m, 2 m), in braided stainless steel, PVC-sheathed or in non-kink anti-twist versions. The diameter of the fittings is standardised (1/2 inch), but some manufacturers offer quick connectors: check the compatibility with your hand shower. To avoid leaks, prefer a hose with brass nuts rather than plastic and an integrated gasket at both ends. PVC-sheathed is the cheapest but deforms with heat; braided stainless steel, more expensive, stays flexible and withstands repeated kinking better, which makes it the best choice for daily use.

Fitting the new hose

1. Wind two to three turns of PTFE tape around the male threads, in the direction of screwing.
2. Screw the top nut onto the hand shower by hand, then tighten a quarter turn with the pliers.
3. Connect the bottom nut to the mixer, taking care not to twist the hose.
4. Check that the hose forms an arc without kinks or twists.
5. Turn the water back on and test both ends with a dry cloth.

Hose, hand shower and column: the special cases

On a shower column (rail with hand shower and fixed head), the hose generally connects at the bottom of the column with a quick fitting: pull on the collar of the connector, insert the hose nut and release. On a hand shower with built-in tap (push-button spray head type), the hose is sometimes sold with the hand shower: check the length provided, because these models often use a special non-standard fitting. Finally, if your hose comes out of the wall without a visible mixer, it is a wall-mounted tap hose: the procedure remains identical, but remember to turn off the mains water, because there is no local valve to isolate the shower.

The mistakes to avoid

• Tightening the nuts excessively, which crushes the gaskets instead of guaranteeing the seal
• Forgetting the sealing gasket at the end of the hand shower
• Twisting the hose while screwing, which weakens it and makes it leak
• Reusing a deformed or cracked gasket

Replacing the shower hose is a plumbing operation within everyone's reach: all you need is a good hose, a pair of pliers and a few turns of PTFE tape. If a leak persists after assembly, check the gaskets at both ends and the presence of the anti-twist spring: in nine cases out of ten, the problem comes from a badly positioned gasket rather than the hose itself.
