Guests at Trenython Manor Resort have mixed feelings about the hotel's pool facilities. While some consider the pool amazing and refreshing, others are put off by the need to book time slots in advance, especially during busy periods like half-term. While some guests found the pool area to be crowded, others enjoyed the first-class spa facilities, including the sauna and steam room. The changing rooms were consistently clean and extra towels were available, according to several reviews. While some guests had to forego using the pool if they didn't book ahead or during peak times, others appreciated the warm, indoor and heated pool, which was sensibly managed. A few guests mentioned that the pool was a little small and the shallow end was too shallow to swim in, but overall, the pool and associated facilities are excellent and the area is kept beautifully clean.
