Hi Carlos, many of our clients choose salt or mineral water treatment systems for their ease of use and their cost effectiveness over time. You add sodium chloride (salt) to your pool and as it is pumped around the filtration system it passes an electrode that creates chlorine gas. This chlorine gas is what sanitises you water killing bacteria and keeping your water healthy. What size is the pool you're looking for as we can let you know the setup costs for a system like this.

Personally I think you are better to wait until you can afford to put back an in ground pool as the one's that I have seen sitting above the ground look like an eye sore - a temp pool - that looks like it could collapse at any time. Maybe while you save for the bigger project you could rent / buy a large Spa Pool.

I am trying to source (in New Zealand) a shower tray which will fit into my alcove Sized 1900x1000 for the shower. Thus far for that size (and I have searched online and in merchants) found only tiled over solution to completely cover floor space. Not totally happy to have this as feel that tiles will be slippery when wet. Whereas have found smaller acrylic trays that are described as non slip even tho they are smooth. Can anyone suggest a supplier that they have used for trays and hinged/pivot doors of the size I require? Or if place a shorter acrylic tray to the length (probably 1200mm) of the glass wall, as will create a walkin with what do I cover the remaining 700mm of the alcove floor? The bathroom floor will not be any kind of tile, more likely to be a textured vinyl plank.

Here is a layout indicating some minimum dimensions for usability. I would recommend you go larger especially if two people are often going to be using the space at one time. This also does not account for window space or furniture or storage.
