Wat Ket’s award winning spa (just check out the trophy cabinet in the spa reception area if you need proof) is part of the facilities at lux hotel, Rarinjinda, which takes wellness very seriously. Thankfully, you don’t have to be a hotel guest to use the elegant spa’s onsen area – a circuit of three pools: the 40-42C ‘Hot Springs Pool’, the more gentle 36-38C ‘Carbonated Soda Spa Pool’ and the ‘Cold Water Pool’ that’s chilled to an easy 16C.
However, the onsen is only accessible as part of Rarinjinda’s ‘Hydro Treatment’ package, which comes in at a cool B1,770 but does include use of their steam rooms and the extremely swanky hydrotherapy pool – one of only two in the city. It’s a large indoor pool in an elevated conservatory-like space with eight separate stations of jet-streamed warm water. Start by massaging your feet, end at your neck then loop back for more.
1, 14 Chareonraj Road, Wat Ket. B1,770 for the 90 minute package. Booking via 053 247 000 or online. 10am-midnight.
