About This Product

If your Kohler shower's temperature control has gone haywire – scalding hot one second, freezing cold the next – odds are the cartridge needs swapping.

78913 Thermostatic Valve Cartridge – Replacement For Kohler K-400, K-401 3/4 Master Shower Valves (Prior To 2006) – Constant Temp Control

This K-78913 thermostatic cartridge is a direct replacement for Kohler K-400-K and K-401-K master shower valves.

78913 Thermostatic Valve Cartridge for Kohler K400/K401 3/4 '' Master Shower

It's the OEM part, so it fits perfectly and works just like the original.

Here's the cool part – the cartridge uses a smart thermal sensing element that expands and contracts with water temperature changes.

Thermostatic Cartridge for Kohler 78913 K-400-K and K-401-K 3/4 Inch

That means it constantly adjusts the hot/cold mix to keep your shower at a steady, comfortable temp.

Thermostatic cartridge for temperature control

No more dancing around trying to avoid a sudden blast of icy or boiling water.
It's all about that consistent, relaxing shower experience.

Built from premium brass, it's safe, odorless, and resists oxidation and rust – so it'll last for years without acting up.
The 3/4-inch size gives you a high flow rate, which is great for those rainfall showerheads or multi-function systems that need good water volume.
