We Londoners are a rather tightly wound bunch, aren’t we? I mean, you can’t really blame us when living in the Big Smoke is a bit like being stuck on a never-ending conveyor belt of busy tubes and even busier diaries. But fear not, frazzled folks – because I come bearing a serene spot that could loosen the shoulders of even the most stressed-out city dwellers.
Hidden beneath the streets of the city, just a stone’s throw from Trafalgar Square, is Thai Square Spa. If the name sounds familiar to you, it might be because this subterranean sanctuary comes from the same brains that are behind the popular Thai restaurant chain. It seems as though they really can do it all.

Thai Square Spa
Serving up rest, relaxation, and rejuvenation by the bucket-load, Thai Square Spa is set inside a beautifully-restored Victorian bathhouse that dates back to the 19th century. The spa’s signature scent of jasmine and rich Thai silk greets you upon arrival, and it’s safe to say that the chaos of the capital will be melted away within mere moments of stepping foot inside the historic building.
Thai Square Spa boasts treatment rooms, massage rooms, a sen space (complete with sauna, steam chamber, and vitality pool), a Vichy shower vault, and two gorgeous relaxation rooms. The space seamlessly weaves Thai, Roman, and Turkish influences to create a truly unique experience. So much so that Thai Square Spa was recently named the best unique spa in Northern Europe – and it’s certainly not too hard to see why.

With each session limited to a capacity of 6 to ensure that every visit feels exclusive and private, and an ambience that I truly didn’t think was possible to locate in the middle of London, Thai Square Spa is the ultimate urban retreat. There’s plenty of packages to choose from, each of vary in length and price-point, meaning that there really is something for everybody. And, to be quite honest with you, I’m now just counting down the days until I’m wrapped in a fluffy robe, sipping herbal tea in the Thai tranquility room again.
📍You’ll find Thai Square Spa at 25 Northumberland Avenue, WC2N 5AP.
