Houstonian Trellis Spa

Trellis Spa sits on the grounds of The Houstonian hotel in Houston's Westside, built as a European-villa-style retreat spread across 26,500 square feet. It's described as the largest luxury day spa in Texas, with 22 treatment rooms covering massage, facials, body treatments, and hand and foot care, plus a separate menu of wellness services developed with The Covery.

The facility centers on more than treatment rooms. Outdoor soaking pools and a sundeck anchor the amenity side, with open-air cabanas, rocking chairs, a fire pit, and a butterfly art installation worked into the design. There's also an indoor pool, relaxation lounge, hot tub, and a restaurant on site serving scratch-cooked meals and daily baking, making it a place where a group or couple could easily spend a half-day rather than just an hour for a service.

Access works differently than a typical day-spa pass. Anyone booking a massage, facial, or body treatment of 50 minutes or longer gets complimentary use of the pools, sundeck, and locker facilities for the day; there's no stand-alone day-pass option for just the amenities. The spa also hosts private groups and gatherings, leaning into its reputation as a social weekend destination as much as a quiet weekday retreat.

It's priced at the upscale end of the market, consistent with its scale and hotel-spa setting, though specific treatment prices aren't listed here and are worth confirming directly.
