Trellis Spa at The Houstonian is widely regarded as the crown jewel of luxury day spas in Texas. Nestled within a secluded 26,500-square-foot sanctuary, the spa evokes the charm of a European villa with statuesque architecture, lush gardens, and timeless beauty. Featuring 22 treatment rooms, indoor and outdoor pools, private cabanas, spa dining, and an expansive sundeck, Trellis Spa offers an elevated wellness experience that extends well beyond the treatment room. From bespoke massages and rejuvenating facials to body treatments, nail services, and holistic wellness therapies, every visit is thoughtfully designed for deep restoration, connection, and renewal — open daily from 8:00 AM to 7:00 PM.
