Bundles — Filter Every Shower in the House

One filtered shower head fixes one room. The chlorine and the hardness are in the supply, not the bathroom — so the ensuite does the same thing to your skin as the main shower does.

Every bundle below is priced so the extra heads are genuinely free: Buy 2 Get 1 Free costs exactly what two cost on their own, and Buy 3 Get 2 Free costs exactly what three cost. Check the arithmetic yourself — that is the point.
