Do I need a special bathtub?

No. Acrylic, enamelled steel, cast iron and freestanding tubs all work. The unit sits beside the tub and the dissolution head drops into the water.

Does it modify my plumbing?

No. There is no connection to the tub's drain, fill or hot/cold supply. The machine uses its own source reservoir filled with distilled water.

What outlet do I need?

A standard residential wall outlet. No dedicated circuit. A GFCI/RCD-protected bathroom outlet is the expected install.

How long does a session take?

Saturation takes 10–20 minutes; a typical soak is 20–30 minutes. The unit keeps running through the soak to hold concentration.

How many sessions per week?

There is no engineering limit. The hardware is rated for daily use. Cadence is a personal routine choice.

How much does it cost to run?

A typical session draws under 500 W for 30–50 minutes — a few cents of electricity per bath, plus the cost of distilled water for the source reservoir.

Can two people share a bath?

Yes, the dissolved concentration is the same across the tub. Capacity is a comfort question, not a hardware one.

Bath One™ is rated for residential bathroom use and runs at a low conversational level. WZ-1™ is slightly louder due to higher output.

How long do these machines last?

With distilled water and routine care, the PEM stack runs for thousands of hours. Most wear items (dissolution head, hose, filter) are user-replaceable.

Can I use one in a commercial spa?
