Cascada C-Type Thermostatic Cartridge | 4, 5, 6, 7 Knob Valves

If your shower is running too hot, too cold, or just refusing to hold the temperature you set — the cartridge is almost always the culprit. The Cascada C-Type Thermostatic Cartridge is a direct replacement designed to restore accurate, stable temperature control to your thermostatic shower valve. One part, properly installed, and your shower works the way it should again.

Before ordering: Confirm your existing valve uses a C-Type thermostatic cartridge and check that your valve dimensions match the specs below. This cartridge is engineered for C-Type thermostatic systems only.

What This Cartridge Does

• Brings back steady temperature — regulates water mixing across a precise range of 59°F to 140°F (15°C to 60°C), so the temperature you dial in is the temperature you get.
• Anti-scald protection built in — every cartridge is individually tested for anti-scald performance before it leaves the facility. Not batch-tested — each one, individually.
• Resists limescale buildup — made from advanced thermoplastic polymer that reduces mineral deposits from adhering internally, extending the cartridge's effective service life.
• Works with multiple valve configurations — compatible with 4, 5, 6, and 7-knob thermostatic shower valves, making it a practical spare for a wide range of Cascada shower systems.
• Washer included — comes with a compatible washer for a proper, leak-free seal right out of the box. Nothing extra to source.

Time to Replace Your Cartridge?

Thermostatic cartridges wear down over time — it's normal, and replacing one is far cheaper than replacing the whole valve. Here are the signs yours needs to go:

• Water temperature shifts unexpectedly during your shower
• The valve no longer holds the temperature you've set
• Hot and cold water aren't mixing correctly
• Performance has dropped noticeably, even with clean water supply

If any of these sound familiar, this is the fix.

Who This Is For

This cartridge is for homeowners and installers who want to restore a Cascada thermostatic shower valve to full working condition without replacing the entire unit. It's also a smart spare part to keep on hand if you're running a Cascada system in a rental property, vacation home, or hospitality setting where downtime needs to be kept short.

Why the Cascada OEM Cartridge

Third-party cartridges can fit on paper and fail in practice — wrong tolerances, inconsistent anti-scald response, or materials that degrade faster under daily use. This is the original Cascada-spec cartridge, built from thermoplastic polymer selected specifically for thermal stability and limescale resistance. It's the same component the valve was designed around. That matters when you're dealing with water temperature in a pressurized system.
