From candlelit thermal baths and salt-water floats to snow rooms and sound baths, these affordable London spa experiences prove that a relaxation doesn’t have to break the bank.
London is excellent at affordable wellness, offering deeply relaxing spa experiences, ancient bathing rituals and clever express treatments that feel indulgent without tipping into extravagance.
From floating weightlessly in near silence to plunging into icy pools followed by eucalyptus steam, these are the best spas and spa treatments across the city that come in at under £100 — proof that luxury doesn’t have to be wildly expensive.

Floatworks — Angel
From £79.99 for two enhanced floats or £99 for three intro sessions.
For pure switch-off, few experiences rival flotation therapy. At Floatworks, private tanks are filled with half a ton of Epsom salts, allowing you to float effortlessly in warm, body-temperature water. The pods are spacious, silent and softly lit — or pitch black, if you opt for full sensory deprivation.
It’s a meditative, almost otherworldly experience that leaves you deeply calm and surprisingly energised.
For more information or to book, visit Floatworks.
Banya No 1 — Hoxton and Chiswick
Packages from £95.
An invigorating antidote to modern stress, Banya No1 delivers traditional Eastern European bathing rituals with theatrical flair.
Expect intense steam rooms, icy plunge pools and the signature Parenie treatment — where fragrant bundles of birch, oak and eucalyptus are rhythmically brushed across the body to stimulate circulation.
