ᐅ Pool equipment: where to plan for it in case of future pool installation

Where should space for the pool equipment be planned if the outdoor pool is to be installed only after the house is completed or possible later?

In the basement with conduit pipes to the pool area? In a separate pool house? In a shaft near the pool?

What is the required space for such equipment?

One important aspect to consider with a pool is the heating. The ideal solution is usually connection to the home's heating system. If there is plenty of space, then solar collectors can also be added. However, this should be planned in advance when designing the home heating system.
The pumps require a significant amount of electricity (often 400V pumps). The main electrical supply must be capable of this, and the wiring in the technical room must be installed accordingly.
Another point to consider is backwashing. Whether automatic or manual, large volumes of water are discharged into the sewer system in a short time. Therefore, the sewer pipes must be properly sized and pressure-resistant.
A single conduit won’t be enough. You might need four or more ducts of 200mm (8 inches) diameter.
No matter where you finally decide to install your equipment, plan for electricity, water, drainage, and possibly LAN connections from the start.

Pool or small swimming pool? A standard pool with a diameter around 4.5m (15 feet) or so does not require such extensive technical installations. However, if the pool holds tens of thousands of liters, a qualified pool designer should provide specific answers tailored to the exact project.

What exactly do you want to build and how much are you planning to spend?

A standard pool is about 8x3 meters (26x10 feet).
A basic technical setup is necessary here: filter + pump. Dosing systems, automatic backwash, etc., increase comfort.
If done properly and comfortably, you should expect costs starting around 25k.
If you want a steel wall pool, it is significantly cheaper but requires more maintenance. It’s basically a more durable paddling pool. That’s probably what nordanney means.

Solveigh will know how large the pool is intended to be. The rest is just guesswork.

Thank you for the detailed responses. The pool should be approximately 8.00m x 4.00m (26 ft 3 in x 13 ft 1 in), as Rick mentioned, fully in-ground and surrounded by patio slabs. A pool heater and a counter-current system would be great, although they are likely to be quite expensive.

Attached is an early sketch of our garden design. The movable wooden deck was just an idea at the time, but we have already dismissed it.

Garden site plan with house, ground floor terrace, pool, lawn, trees, seating area, sandbox, and paths.

@Solveigh thanks for sharing your plan.
It seems like a great plot.
A movable deck is nice but quite expensive. You probably decided against it for this reason.
For an 8-meter (26-foot) pool, a counter-current system is essential if you want to swim properly.
Pool depth nowadays is usually set to a maximum of 1.40 meters (4.6 feet). Greater depth doesn’t add much benefit for swimming but increases the effort (larger filters, pumps, heating costs, etc.) due to the higher water volume.
Since you’re far enough from the house, installing the pool afterwards is quite feasible. Besides the construction space, you need about 1 meter (3.3 feet) of installation space around the pool (which will later be backfilled and covered). Have you already considered what type of pool you want or how surface water will be drained? With standard skimmers, there would be a significant height difference between the terrace slabs and the water surface. Flat skimmers are more expensive but reduce this difference somewhat. Alternatively, you could install a channel around the pool. Plastic doesn’t look very good, stainless steel is expensive... but then you’d be almost level with the slabs. An overflow pool isn’t suitable in your case and would be even more expensive.

Under your deck would be a good spot for the pool equipment. I would definitely have this space included during the house construction. The pool waterline should be below the ceiling of the equipment room; otherwise, the compensation tank won’t work properly.
You’ll need:
- Electricity (230V and 400V) for pumps, filters, dosing systems, pool cover, underwater lights…
- Water supply
- Wastewater connection
- Optional LAN
- Optional heating connection

On or at the deck, provide power outlets and a water connection for the pool robot and for cleaning the pool robot or pressure washer…

You should already start thinking about the heating system. If you have a gas heater, the easiest solution is to install an additional line and buy a significantly larger boiler. A large heat exchanger can be connected to this line later.
Alternatively, you could install a heat pump in the garden later and hide it. It will need to be winterized though… Or the classic option with solar collectors. In my opinion, this looks unattractive if you can’t hide them on a roof.

Thank you, Rick, for the detailed response. The plot is actually not bad, but it does have a 16m (52.5 ft) height difference. That’s why we started planning the garden early. Although, at this early stage (ahem, 2.5 years of planning time), you never really know if there will be any money left for a pool by the end of construction. So, I prefer not to bother specialist companies with detailed questions yet, since I don’t know if I will be able to hire them. How is this usually handled during construction, when you’re unsure whether you can actually commission certain services?

Swimming pool is a yes, a counter-current system would need to be installed.
A water depth of 1.40m (4.6 ft) is sufficient.
A surface skimmer should be enough; a channel at the top and an overflow system are not necessary.
Heating is essential—brr! However, we have planned an air source heat pump for the house only, sized solely for the house. Photovoltaic panels will be installed on the house roof, with battery storage. Would it be necessary to install a separate heat pump for the pool?
