Silom’s  Infinity Spa looks like a stylish laboratory with its raw concrete floor, mint green walls, yellow ceiling and industrial furnishings—all courtesy of a team from Chulalongkorn’s Faculty of Architecture.

The spa programs run from head to toe (including mani-pedis) and use both Thalgo and homemade products. Relax-atherapy (B1,050/hr) is a pocket-friendly, 60-minute massage featuring home-made oil, while Infinity Jetlag Facial (B2,900) is a Thalgo treatment that claims to revive post-long-haul-flight skin.

For nails, a manicure using OPI products starts from just B500. Check the website for rotating promotions.
