Trellis is the newest, fanciest day spa in Houston. From the interior float pool to the Mediterranean-style balcony, this 17,000-square-foot spa wraps up luxury and serenity into one nice package. Visitors can relax with a Vichy rainfall shower or a tension relief cocoon body wrap. Those self-conscious about baring their aging bodies before the ultrafit Houstonian crowd can opt for a cellulite or stretch mark treatment. And for couples who can't bear to be separated even for a facial, the Trellis offers treatment rooms and hot tubs for use a deux.
