TOPARGEE Showermiser IN WALL No Mixer
Topargee Showermi$er Chrome In-Wall (No Mixer)
The Topargee Showermi$er (SKC002) is an in-wall water-saving diverter that redirects cold water back into your fresh water tank while your shower heats up, instead of letting it run down the drain. A patented colour-change “Magic Mushroom” indicator turns from blue to white in around 4 seconds once hot water reaches the outlet, so you know exactly when to flip the lever and step in.
This chrome in-wall version fits behind existing tapware and connects into the non-pressurised side of your water system, so no mixer tap needs replacing. It's supplied without a mixer — use it with your existing mixer/tap, or pair it with Topargee's matching mixer unit if you're starting from scratch.

How do I know this will fit my setup?
Check the ports and installation details listed in the Specifications tab against your existing tapware and water system. If you're unsure, contact us with details of your caravan, RV, or boat and we'll confirm compatibility.
What's the warranty?
This product is covered by Topargee's 12-month manufacturer warranty. Contact our team if you need to make a claim or have a fault.
Do I need to buy a separate mixer?
Yes — this No Mixer version is designed to work with your existing shower mixer/tap. If you'd prefer an all-in-one unit, Topargee also sells an In-Wall version with the mixer included.
How does the Showermi$er know when the water is hot?
A patented “Magic Mushroom” indicator changes colour from blue to white once hot water reaches it — usually within about 4 seconds at room temperature — so you can flip the lever to shower flow with confidence.
Where does the diverted cold water go?
It's routed back into your fresh water tank rather than down the drain, so the water you'd otherwise waste waiting for hot water stays usable — useful for extending fresh water and reducing grey water tank fill-ups when travelling off-grid.
Will it fit my existing tapware?
Yes. It connects into the non-pressurised side of your water system behind the wall, so it works alongside your existing tap/mixer without needing to replace it.
Is installation straightforward?
It's an in-wall fitting, so some plumbing know-how (and possibly minor wall access work) is needed. Topargee publishes a step-by-step installation guide for this exact model if you'd rather DIY, or your installer can fit it during a bathroom refit.
