What changes

Your first six months.

Day 1
The water feels different from the first shower.

Both filter systems work as described. The water from the kitchen tap tastes nice and fresh, whilst the shower water doesn't feel gritty anymore.

Looking back
The one they tell their friends to buy.

I spent months agonising over filters for our house. I wanted a bath filter specific for the kids as one suffers eczema. I was weighing up between this and another brand who did bath filters, when a friend said just get the shower filter and fill the baths with the shower!. It has been a game changer! No more eczema. No chlorine smell in the water! Softer hair, softer skin. We live in the NT and our water is highly treated. If I could recommend any person on the fence just get the shower filter. I'm grabbing the tap filter next.

90%+of chlorine removed · across the cartridge's whole life

Chlorine strips your scalp's natural oils — that's the roughness after a long shower. Filter it out and the oils stay where they belong. Most people notice within a week, same shampoo.

"It was super easy to install and noticed the difference straight away. I used to get really dry skin and frizzy hair until I started using this, best investment ever!"

★★★★★Sarah · Sydney✓ Verified buyer
See how the 4 stages do it
#1reason colour fades — chlorine oxidising the dye

Chlorine reacts directly with hair dye from the very first wash. A shower filter is the cheapest way to make a $200 salon visit last meaningfully longer — cheaper than any colour-protect product on the shelf.

Protect the next appointment
known triggers removed — chlorine + hard-water minerals

We don't make medical claims. Chlorine and hard-water minerals are known skin irritants — ShowerPro removes the trigger, not the condition. Kids' bath? Fill it from the filtered shower head.

1wash — when most owners say they notice

Dogs have thinner skin than we do. The same chlorine that dries us out makes them itch — and they can't tell you, they just scratch. Wash them under filtered water and watch what stops.

Better baths from $109.99
80%less limescale forming · on glass, tiles and the head

The white crust is hard-water minerals drying onto every surface. The scale-inhibitor stage stops most of it forming — honest version: it doesn't soften your water, it stops the crust. Less scrubbing either way.

It twists on by hand and twists off the same way. No damage, no permanent install, nothing to explain at the inspection. When you move, it moves with you — and if the new shower needs a swivel adapter, we send one free.

60days to find out — full refund if you don't

Fair. Most people notice within a week — and some genuinely don't. Here's a review we could have hidden and didn't. The chemistry works either way, but if your skin doesn't tell you, the 60-day guarantee means you're not stuck with it.

"Installation was easy, and the price is good. I personally haven't noticed softer hair or skin, but I guess the shower filter could be making a difference, I just can't tell."

Forever Fresh · Lifetime Warranty

The last shower filter you'll ever buy.

A lifetime warranty for everyone who keeps their cartridges coming — here it is in plain words.

Here's our deal.

Everything you use every day eventually wears out — your shoes, your brake pads, your phone battery. A shower filter lives a harder life than most things you own: hot water through it twice a day, every day, in the steamiest room in the house. And no filter is immune — ours included. The difference is whose problem that is. With most brands it's yours: one worn-out part and you're shopping for a whole new system.

Not ours.

You will never pay for filter hardware again.

Keep your refill cartridges coming — on subscription, or buy them yourself as they're due, we don't mind — and the hardware is ours to keep perfect, for life. A thread past its best? A housing that's done years of hot showers? A new place that needs a swivel adapter? The right part is in the post, free, from Sydney. No receipts, no claim forms — order it from your account page the same way you'd order anything else.

Trying it out first? The usual Australian consumer guarantees apply, like with anything you buy — and the day you start your first year of cartridges, the lifetime promise starts with it.

Keep the cartridges coming, and you'll never buy this filter twice.

Questions

Common questions.

How will I know it's working?
+
Within a week, your hair will feel different — softer, less straw-like. By two weeks, the white crust on your shower head and glass starts to disappear. The biggest tell: your existing moisturiser will suddenly seem to work properly. If you want a hard test: install ShowerPro on one bathroom and not the other for two weeks. Most people pick the filtered one without knowing which is which.
Why does the cartridge need replacing every 6 months?
+
Two reasons. First, capacity — the cartridge is rated for 10,000–20,000 litres, about 6 months of normal showers. Past that, chlorine reduction starts dropping below the 90% spec. Second, biology — the activated carbon inside is organic and over time can become a substrate for bacteria, even if you use the filter less. Single-person households tend to hit closer to 6 months; larger households closer to 3–4.
Will it reduce my water pressure?
+
No. ShowerPro flows at the same rate as a standard ½″ shower arm — most people can't tell the difference between filtered and unfiltered in a blind test. Low-pressure systems work exactly the same. We don't add a restriction.
Will it fit my shower?
+
Yes. Australian shower arms use a standard ½″ thread, the same as the rest of the world. If your current shower head unscrews, ShowerPro fits. We've yet to find an Australian shower it doesn't work on. If your shower arm sits too close to the wall (less than 3.5cm gap), email support@tappwater.com.au and we'll send a free swivel adapter.
Diamond or Rain — which one?
+
Diamond is the filter alone. It screws onto your existing shower head, filters water as it passes through, you keep the head you already have. 4 filtration stages. Rain is filter + integrated showerhead, with our Swedish Mineral Rock™ stage that adds calcium, magnesium and potassium back into the water. 5 stages. The minerals are the difference — they're the upgrade for people who want their shower water to feel "richer," especially with eczema-prone skin.
Does it remove fluoride?
+
No. Fluoride is a very small molecule — only reverse osmosis at high pressure can remove it, which isn't practical for a shower fitting. ShowerPro targets chlorine, heavy metals, chlorine by-products and hard-water minerals — the contaminants that actually affect your skin and hair. For fluoride-free drinking water, the EcoPro RO Countertop handles that.
Why 90% chlorine? Some other brands claim 99%.
+
Honest answer: most filters claim higher numbers than they can hold across the cartridge's full life. Some brands tell you 99% but the lab data only validates that for the first week — performance drops sharply after. Our 90% is the spec across the entire rated capacity, validated by independent labs (iTabe and AQA). The actual chlorine taste and smell reduction — what you'll notice in the shower — is 95%+. We'd rather lead with the conservative number than make a claim that fades after a month.
Is it safe for colour-treated hair?
+
Yes — and arguably essential for it. Chlorine oxidises hair dye, which is the #1 reason colour fades fast in the first wash. Removing chlorine before it touches your hair makes salon colour last meaningfully longer.
Does it help with eczema, dandruff, sensitive skin?
+
Many of our customers with sensitive skin tell us it does. The mechanism is real — chlorine and hard-water minerals are known triggers for after-shower itching and flare-ups, and removing them creates a gentler shower environment. We don't make medical claims. If you have a diagnosed skin condition, talk to your GP or dermatologist — ShowerPro isn't a treatment, it's a way to remove a known trigger from your daily routine.
Does it need cleaning?
+
No. Water flows the same on day 180 as day 1. If the chrome housing develops a bit of limescale on the outside (it shouldn't, since you're now filtering 80% of it), wipe with diluted vinegar. Pop the refill out before you clean — keep water away from the cartridge.
I'm a renter. Can I use this?
+
Designed for it. Twists onto your shower arm in 60 seconds. No drilling, no plumber, no damage to the property. Take it with you when you move — if the new shower needs a swivel adapter, we'll send one free.
What if I'm not happy?
+
60-day money-back guarantee, no questions asked. If your hair and skin don't notice within two months, send it back. And as long as you keep your refill cartridges coming, every part — housing, fittings, adapters — is replaced free whenever it's needed, for life, under the Forever Fresh Guarantee.
