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. 🙂

majuhenema30 Jul 2021 21:06I’ll share my impression of the consultation meeting. It is a family-run business with around 30 employees. Our contact person was very friendly, first showed us several pools, sizes, and options in the showroom, and then took plenty of time to prepare the offer.
Material:
They usually use 8mm (0.3 inch) thick polypropylene (PP) panels, with the option to upgrade to 15mm (0.6 inch) for about 30-35% more, although they rarely do this.
Pool size:
We asked for quotes on a smaller version measuring 6.7 x 3.3m (22 x 11 ft) and a larger version at 9 x 3.7m (30 x 12 ft), each with one or two skimmer-mounted underwater lights.
Counter-current system:
We decided against the counter-current system because this model would have cost 3,500 euros and apparently wasn’t suitable for (sport) freestyle swimming. The employee’s comment was, “For that price, you could make the pool 3 meters longer.”
Covering:
For pool covers, he gave us the net price for an in-floor roller cover of 9,000/10,000 euros for the smaller pool and 11,000/12,000 euros for the larger one. Alternatively, there is the option of a manual pole cover costing about one-third of that price.
Technical equipment:
Regarding technology, we planned for automatic chemical dosing, without flocculants or special anti-algae agents. He also pointed out that for a bigger pool, the heating engineer must be explicitly informed about the heat exchanger so they might install a larger heating system or we might need a dedicated heat pump for the pool.
We expect to receive the offer in three days.
What are your thoughts on my impression?
How do you feel about in-floor roller covers versus pole covers?
How much would the issue of “heating might need to be larger because of the pool’s heat exchanger or perhaps a separate heat pump” worry you?

Algaecide is not necessary for a pool. Flocculants are rarely needed and usually only available in tablet form.
If your heating system is not significantly oversized, you will need a separate heater (e.g., heat pump). For colder seasons, approximately 0.75 kW of heating power per cubic meter (m3) of water is required. In summer, 0.5 kW per m3 is sufficient.
I would always recommend an automatic pool cover. Simply press a button and you’re ready to swim. Manual covers are always a hassle, and the pool ends up being used less often.
What kind of filter are you considering? Variable speed pump? Control system? Automatic backwash? ...
A counter-current system makes sense for pools up to about 15 meters (50 feet) in length. Beyond that, it’s generally not necessary. However, the system should be powerful enough to allow proper swimming. It’s also useful for playing and cooling off. Consider preparing the installation space during construction so you can add it later if needed.

The heat exchanger must deliver its performance at 35-40 degrees Celsius (95-104 degrees Fahrenheit) and not as usual at 70-90 degrees Celsius (158-194 degrees Fahrenheit).
I suspect you will need a separate heating system. I don’t think you have 20-25 kW available "left over."
How deep are the pools?

majuhenema30 Jul 2021 22:13Thank you! The depth is 1.5 m (5 feet). Besides the additional space requirement and purchase costs, does an extra heat pump for the pool have any other disadvantages? We are getting a photovoltaic system for our air-to-water heat pump. I plan to fully utilize the flat roof.
