Hotel Indigo London K West Shepherd's Bush
Why we pick itThe old K West reopened in March 2026 as a Hotel Indigo after a refurbishment, and the rebuilt spa is billed around a thermal area, spa gardens and treatment rooms. Day passes for non-residents had not reopened when we last checked, so treat this as one to ring rather than book online.
Worth knowingReopened in March 2026 as Hotel Indigo London K West after refurbishment. Listings showed the spa unavailable into late 2026 and no day-pass price is published, so check before travelling.

Before you book
Midweek and off-peak passes are where the savings are, so be flexible on timing. Look at the dedicated thermal and day spas as well as off-peak hotel deals. And check exactly what is included; the best value comes from a pass that covers the facilities for the whole day, not just an hour.
