If you step out of your spa feeling itchy, dry, or irritated, it’s not “sensitive skin.” It’s the chemical cocktail sitting in your water — and most spa brands won’t tell you this.
Traditional spa chemicals are designed for constant re-dosing, leaving excess residue on your skin.
Result: dryness, irritation, itchy skin after soaking.
Fix: Spa Monthly works once a month, cutting chemical exposure without sacrificing clean water.
Strong odours come from harsh chemicals reacting with oils, sweat, and lotions.
Result: stinging eyes, irritated skin, and water that feels harsh.
Fix: Spa Monthly keeps water fresh and clear without the chemical stink.
Hot water already dries skin — aggressive sanitizers make it worse.
Result: tight, flaky skin and rashes after soaking.
Fix: Spa Monthly is human-safe and gentle, helping water feel smooth instead of stripping.
Most spa products focus on looks, not feel.
Result: water that looks clean but feels rough on your skin.
Fix: Spa Monthly improves how the water feels, not just how it looks.
Weekly treatments lead to buildup that throws your water out of balance.
Result: more maintenance, more products, more irritation.
Fix: Spa Monthly simplifies care with fewer additives and less upkeep.

I’ve had a hot tub for most of the last 30 plus years. Many brands. Have used countless combinations of chemical support to keep them clean. Finally found one I’ll stick with. Love this product. Easy monthly application with very occasional additional need to add extra in between.
I have been using eco one products for 18 years & they are simply the best. Spa water is always clean & clear. So much better than chlorine.
Spa Monthly is a must! My water is so clear due to Spa Monthly. I always keep it on hand for my monthly routine.
This system is so easy and trouble free. My water is always perfect and I don’t have to buy multiple chemicals and jigger with it constantly.
I keep my hot tub water chemical levels perfect but unfortunately my skin is super sensitive and when I would get out my skin would be super itchy! This stuff is amazing, my skin stopped itching and feels great. I’d highly recommend this stuff if you have skin sensitivity issues.
This product works great. I use this monthly and the Eco One shock granules after each use and that’s all that’s needed to keep the water clear.
Many traditional chemicals aren’t biodegradable and rely on unnecessary preservatives.
Result: water that’s rough on your body and the planet.
Fix: Spa Monthly is earth-friendly, biodegradable, and never animal tested.
Constant adjustments and shocking mean your water isn’t truly balanced.
Result: ongoing irritation and endless maintenance.
Fix: Spa Monthly addresses the root cause with one simple monthly dose.
Turn on jets and blowers. Pour one bottle directly into your spa. That’s it.
No measuring. No weekly dosing. Just clean, comfortable water.
Start with cleaner water by filling your spa using the EcoOne Hose Filter. It removes contaminants before they ever touch your skin.
Back in 1997, our founders wondered if there was a way to make spas fun for everyone, especially those with sensitive skin. At the time, most commercially available spa care products led to rashes, dryness, and irritation—so we got to work.
The result is EcoOne, a complete line of spa care products that keep your tub and its accessories sanitized, sparkling, and welcoming to all.
As it turns out, our skin-friendly ingredients are Earth-friendly, too. In fact, many of our products can even be used while you're in your spa. When you switch to EcoOne for your spa maintenance routine, you won't need to stress out about your environmental impact. Our products are for people who think beyond the backyard.
