Pool conversions and modifications in Geneva and Vaud

Does your 20-year-old pool no longer meet your needs? Too deep a plunge pool, no stairs, excessive water volume…

Astro Piscines radically transforms the ergonomics of your concrete pool, from Geneva to Lausanne.

Depth reduction: Switch to flat bottom

This is the #1 demand in the Lake Geneva region. The old diving pits (2.50m) are expensive to heat and not very user-friendly.

Advantages of flat bottom (1.40m) :

– ✅ Everyone on foot – family pool

– ✅ Water volume reduced by 30%.

– ✅ Faster, more economical heating

Creation of stairs and submerged beach

Gone are the days of impractical stainless steel ladders. Take advantage of the renovation to build a real comfort access, then cover it with non-slip reinforced PVC.

  • Corner or full-width staircases: for secure access.
  • The Californian Beach: A shallow area for lying in the water.

Securing and insulating: Replacing roofing

Structure isn’t everything. A successful renovation requires a high-performance cover to keep the pool warm and safe, in line with Swiss standards. Is your current cover torn or manual? We install modern solutions:

FAQ – Pool conversion

Can I reduce the size of my pool?

Yes, it’s common to reduce a large pool (e.g. 10x5m) to a standard size (8x4m) to save terrace space and reduce maintenance costs. We build a separating wall in breezeblock into the existing pool.

How much does a depth reduction (flat bottom) cost?

The price depends on the volume of backfill (gravel) and concrete required, as well as access to the site for machinery. It’s an investment that quickly pays for itself in heating and water savings. Ask Astro Piscines for a precise quote.

Can a shell pool be converted?

No, these heavy structural modifications (creation of stairs, change of bottom) are reserved for concrete, breeze-block or lost casing pools.
