Shower Mixer Handles & Knobs

How to identify yours

• Pull the old handle: loosen its grub screw and look at what it sat on.
• Toothed brass spindle: measure it and count the teeth. This is the top dial on two dial valves, or the on/off and divert dial on a thermostatic valve.
• Square plastic stem: the bottom dial on a two dial mixer that you lift and turn for flow and temperature.
• Lever: measure the width of the cartridge and the joystick the lever grips. Then compare the old handle’s size with the sizes on each listing.

Symptoms and likely causes

Handle spins or feels loose: the grub screw has worked loose, or the spindle has worn. See a knob that spins.

Stiff or hard to turn: usually nothing is broken, so a new handle won’t cure it. See a stiff control knob.

Drip from round the dial: a worn seal in the valve behind it, not the knob. See a dripping control knob.

Water stuck hot or cold: a handle that has slipped off its true position is worth ruling out. See water stuck on hot or cold.

Which handle fits your valve

These are matched by fitting, not by cabin brand. If yours isn’t here, a photo will confirm it.

Fitting tip

Before you replace a stiff handle, wrap a bag of white vinegar round it and leave it to soak, then work it gently. Limescale round the spindle is the usual cause.

When to call a professional

Changing a handle is a basic tools job. If the fault is behind it, a drip, a stiff cartridge or water that won’t turn off, isolate the water before you take the valve apart.

Frequently asked questions

Do they come with a grub screw?

Yes, every handle on this page comes with one.

What are they made of?

Zinc alloy.

Is a 24 tooth spindle standard?

Our dials fit a 7.5mm brass spindle with 24 teeth, which the listings call standard for most mixers. Measure the width as well as counting the teeth: some cabin valves use an 8.5mm spindle with 24 teeth, and our dials won’t grip it.

How big are they?

Our dials run from 42mm to 69mm across, and our levers from 84.5mm to 123mm long.

Handle already off? Photograph the spindle end straight on, beside a ruler, and we’ll match it.
