I’m about to commit to a swimming pool in the garden. In ground 8x4m. Before I do I’d be grateful to hear from anyone who has one and regrets it or any must haves/must avoids. It would have a ground source heat pump and is the type without external pump/pool house which saves space and cost. It’s a huuuuge investment for me so having last minute cold feet. But everyone I speak to in real life say their only regret is not doing it sooner.
