The questions
we hear most

An eco-pool is a natural swimming pool that uses biological filtration instead of chemicals. Microorganisms break down dissolved organic matter and keep the water clear — without chlorine, algicides, or pH correctors. The same swimming experience — without the chemistry.

The nutrients introduced are broken down in a natural process by the biofilm that forms in the filter. This is a natural process. Input and output must be in balance.

Around 40 watts running continuously — about the same as a laptop running continuously.

No. The biological filter keeps the water balanced year after year. You only top up to replace what evaporates.

None. No chlorine, no algaecides, no pH adjusters. Ever.

One to two days. The Badebrunnen arrives pre-built and is installed by our certified technicians with minimal groundwork.

Kalt is unheated freshwater — refreshing cold-water bathing through spring and autumn. Warm adds electric heating and insulation for year-round freshwater use. Floating combines heating with natural sea-salt water for a silkier feel and year-round wellness.

Starting at CHF 19,300 for Badebrunnen Kalt. Warm starts at CHF 20,550, Floating at CHF 27,050.

Depending on usage, the filter needs backwashing 2–4 times per year.

Yes — the Warm and Floating models are heated and insulated for year-round bathing. The Kalt model is best enjoyed spring through autumn.

The eco-pool is a full-size, custom-built residential pool. Dimensions, finish, and equipment are tailored to your garden. The Badebrunnen is the compact, pre-engineered version for terraces and smaller spaces.

Zero is the essential configuration — just the pool, biological filter, and safety cover. Bestseller includes a heat pump, integrated lighting, and an underfloor roller shutter — everything ready for year-round wellness.

Three to five days, depending on size and groundworks.

Yes — heating and cover can be added at any time. The Zero model is the most sustainable entry point; you only add what you actually need.

The upfront investment is comparable or slightly higher. Long-term operating costs are lower — no chemical purchasing, no daily logs, no specialist staff, and dramatically reduced energy consumption.

It doesn't. Biological filtration keeps the water balanced indefinitely; only evaporation needs topping up.

A regular robot vacuum cycle. The filter itself is never replaced.

The biological filter is sized to the pool's expected capacity. It's modular, so capacity can be expanded later without major construction.

Minimal. No daily pH or chemical measurements, no dosing schedules. The system regulates itself; your team handles the regular robot cycle.

No chlorine gas, no chemical smell, river-like water that feels softer on the skin. The air in the pool hall stays clean and breathable.

One day of onboarding is enough. No certifications, no specialist hires.
