## Overview

Mantle Thermal Haus is a small indoor-outdoor contrast spot on Curtis Ave in East Austin. You check in through a lobby with drinks and apothecary goods, change in one of two shower rooms, then head outside to two cedar barrel saunas (six people each) and three two-person cold plunges. In my opinion it is the most straightforward sauna and plunge hour on the east side, with red light and massage as extras rather than the point.

A one hour drop-in is $35 and a 10 Pack is $275, which puts it right next to the cøntrast Garden on price. Memberships run $100 a month for four visits up to $250 for unlimited. Bring a swimsuit, and note the short Monday hours (7am to 11am).

## What to expect

- Two separate 6-person cedar barrel saunas in the outdoor space
- Three separate 2-person stainless steel cold plunges
- One hour sessions; check in at the lobby, then change and rinse in one of two shower rooms
- Red light lounge with full-body red light blankets and massage on the indoor side

## Practical notes

- Wear a swimsuit or athletic clothes; you will get wet. Sandals and a towel are recommended
- Bring a water bottle; there is a filtered water station on site
- Monday is mornings only (7am to 11am); Tuesday to Saturday 9am to 7pm; Sunday 10am to 5pm
- Want a private room nearby instead? cøntrast on MLK has a private infrared suite with its own plunge
