Royal Crystal Sauna Spa - Seelze

The Kristall Sauna-Therme in Seelze, featuring a lap pool, is lavishly appointed and inspired by the gardens of castles and manor houses. It offers a wide variety of swimming, sauna, and wellness options with something to suit every taste. All indoor and outdoor pools are filled with precious thermal brine water from Lower Saxony, making bathing at 34–36 °C with a brine concentration of 3 to 12% a true pleasure. Visitors can also look forward to a spacious outdoor area—the Sauna Village with paths for strolling and comfortable loungers for sunbathing, an ice grotto for that extra special burst of freshness after a sauna session, and an Ottoman hammam for relaxation or to enjoy a soap-scrub massage, among other things.
