We try to provide all popular cartridges for Ideal Standard & Armitage shower and bathroom controls from stock. Choose 1/2 inch cartridges for Basin & Bidet controls, most Bath and Shower controls are 3/4 inch. Ceramic Disc are 1/4 turn, whereas conventional Screw Down cartridges reuire several turns to fully open/close. Ceramic Disc cartridges tend to be clockwise close for HOT and anti-clockwise close for COLD.
Single lever mixers use a single joystick style cartridge (small for Basin/Bidet, usually large for Bath/Shower).
Thermostatic mixers contain both flow cartridges (its leaking, wont turn off or drips) and a temperature cartridge (too hot, too cold, no steady temperature).
Officially Ideal Standard only supply spares for models up to 10 years old, in practice many older models have the same cartridge as recent models.
