Kelo Spa

Kelo Spa is a banya-style bathhouse built from kelo timber imported from Lapland, tucked into a storefront in Newton Highlands. The core visit is a three-hour general admission session that includes robe and towel service plus access to the kelo sauna, steam room, cold plunge and a lounge area stocked with a juice bar.

Admission runs $69 when booked online in advance; walk-ins are welcome but pay $89 and aren't guaranteed a spot if the space is full. The schedule alternates by gender: Mondays and Thursdays are men-only, Tuesdays, Wednesdays and Fridays are women-only, and weekends split the same way (Saturdays women, Sundays men) during daytime hours. Saturday and Sunday evenings from 6 to 9pm are reserved for private bookings, which run from $1,000 for up to eight people with additional guests at $125 each, capped at 24 total.

Beyond the basic pass, there's a short menu of add-on treatments performed by staff, including the signature Platza (a full session runs $80, a half session $50), a scrub service, foam wash, salt and honey glazing, and Dead Sea mud treatments for face or full body. Six treatments total are offered alongside the sauna circuit.

This is a no-frills, single-purpose spot built around the sauna experience rather than a broader treatment menu. Anyone planning a visit around a specific day should check which gender is scheduled, since the split changes daily rather than following a fixed weekly pattern for men versus women.
