ᐅ Building a Pool at the Same Time as the House - Your Opinions?

Dear community,
Since December 2020, we have been planning our house and reached an agreement with a provider in April. See:
https://www.hausbau-forum.de/threads/erste-grundrissplanung-auf-karopapier-hang-keller-2-geschosse.37567/
During the planning, the topic of a pool was always in the back of our minds and was discussed several times. Our initial feeling was "let’s build it right away," which over weeks and months shifted to "preparation now and realization later" for the time being. Now our direction is changing again, and we are researching construction and maintenance costs. Since it is difficult to assess the reliability of the various sources, or they do not align with our idea, we would very much appreciate feedback from the community here.
We are looking at a pool size of 8 x 4 meters (26 x 13 feet) without a counter-current system but with an electric cover. We are not entirely sure about pool heating. The technical room is located in the basement near where the pool will be installed.
We keep telling ourselves that building the pool now would be much cheaper because pool and house work could run in parallel, creating synergy effects (economic and legal aspects included 😉 ) regarding earthworks, foundation, crane use, and technology.
Our questions are:
1. In general: What do you consider to be the best type of pool for our project? We know the pros and cons of various types but cannot come to a final conclusion.
2. How much would you estimate the pure construction costs of your “preferred option” under the above conditions?
3. How large do you estimate the price difference between “building now” and “doing it in xx years” to be?
Thank you. 🙂

I’m also considering planning a mini pool (more like a small plunge pool for relaxing). The view from the spot is wonderful, and the garden is definitely large enough, so the conditions are ideal. Once the house is built, heavy equipment would only be able to reach the garden indirectly.
I’m still undecided about the material. I thought the easiest way might be to have it excavated and concreted directly during the shell construction. Inside, then tiled, possibly with greenish-blue mosaic tiles. I find that the most attractive. The material is now decided. It will be a pool made of waterproof concrete (WU concrete) and painted with pool paint. According to the pool builder, this is the most sensible solution in terms of cost and durability. The pool equipment will be housed in the basement, located 3 m (10 ft) away. There is a large, rarely used basement room, from which a small chamber will be separated using drywall construction.
Regarding the pool cover, since this was also discussed here: a safety roller cover will be installed that does not touch the water. It will be supported by aluminum pipes resting on the pool edge. Since the pool is only 6 m² (65 ft²) in size, I consider this the most practical solution. The cover will be rolled up manually with a crank handle. I didn’t want unnecessary and complex technology, which wouldn’t be worthwhile for such a small pool.
I still need to think about the practical usability of the pool in winter. Most likely, however, the pool will simply be shut down in winter, meaning the water will be lowered below the skimmer level and no cover used.

You don’t even need to consider stainless steel pools. They’re significantly more expensive. Could you please provide an approximate figure? If a 6x3x1.5m (20x10x5 ft) pool made of concrete + liner + automation + cover etc. costs around 60,000, how much extra would stainless steel be? What type of steel is it—1.4404/V4A? I work a lot with steel construction, and standard stainless steel isn’t usually that expensive... We are also planning a pool for our house (more like 12x3x1.5m [40x10x5 ft]), and we definitely prefer stainless steel over liner.
One more question: why 12°C (54°F) in winter and not lower? Since we don’t have gas, a heat pump for the pool is necessary, so I need to manage energy use carefully.
Depending on the manufacturer, it is usually V4A stainless steel; a few enthusiasts also use V4S. Cheaper (or rather low-quality) options sometimes use V2A, which is actually not suitable and only works for a limited time with passivation.
The price factor for the basin is about 2 to 3 times higher. The rest of the equipment remains unchanged. Usually, higher-end pools feature more automation and better components, which further increases the overall cost. With your pool size, you will likely be looking at a price close to six figures.
The 12°C (54°F) temperature is due to the cover. At lower temperatures, not enough heat passes through to melt snow and ice on the cover.
Alternatively, you can drain water under the inlet nozzles, retract the cover into the water, and cover the pool with a tarp. In this case, you don’t need to heat the pool at all.

We have now scheduled three consultation appointments. Two companies have a very good reputation in our area. One of them informed us about this directly. A third company manufactures the pools themselves from polypropylene (PP). Could someone explain to me how this material compares to fiberglass reinforced plastic (FRP/GFRP)?
Do you have any tips for the initial meeting? We are fairly certain about size, technology, and features. What else should we do or avoid, mention or not mention? 🙂

Let the pool builders first make some proposals. This way, you get a feel for how and with what materials they work.
After that, you can still express your preferences regarding the technical aspects.
Have the pros and cons of each construction method explained to you.
PP pools are made by welding panels together, so visible weld seams are present.
PP pools can be heated to high temperatures without any problems.
They require more reinforcement, meaning more concrete.
GRP offers more freedom in design, for example with curves, and is more durable.
PP is somewhat cheaper and the material is softer.

Myrna_Loy30 Jul 2021 09:47GRP is more durable and can be repaired and repainted. However, at the end of its service life, it becomes hazardous waste. It is a traditional boat-building material (if you are not building with wood). My parents’ neighbors have had their GRP pool since the 1980s. Polypropylene is not really repairable, and depending on the quality, I would estimate its lifespan at a maximum of 15-20 years. However, it can theoretically be recycled.
