About Sanadome
Sanadome, Netherlands is a paid thermal spa resort at Weg door Jonkerbos 90 in Nijmegen, Gelderland, set in the Jonkerbos woodland on the south side of the city. The facility opened in 1995 and operates from two of its own springs: a freshwater spring and a thermal saltwater spring; the saltwater pool produces a buoyancy effect comparable to the Dead Sea. Sanadome holds the European Ecolabel since 2006. Swimwear is mandatory every day. Children aged 8 and over are admitted with an adult; children under 8 are not admitted.
Pools, Facilities, and Hotel
The 2,500-square-metre thermal landscape includes a large indoor pool at 33 degrees Celsius, a large outdoor pool at 33 degrees Celsius, 340 square metres of whirlpools with added oxygen and carbonated herbal options, a saltwater bath, hot water baths, a mint room, a steam room, and a sunbathing area. All pools use mineral-rich water from the resort's own springs. The 4-star superior hotel has 106 rooms, most with balconies; hotel stays include two days of thermal bath access and fitness use. Four on-site restaurants serve wellness-focused, locally sourced cuisine. A beauty centre with 21 treatment rooms and the Sanasport Health Club complete the offering.

Suitability & Accessibility

The Dead Sea saltwater bath and the 340-square-metre whirlpool area are the most distinctive features for those interested in therapeutic water experiences.

Planning Your Visit
Online reservation is required for all visits. Evening tickets from 16:00 offer a price reduction suited to shorter sessions. The outdoor pool is most popular in summer; indoor facilities run year-round. Aqua gym classes are free for all thermal bath visitors and run daily at set times without registration needed. Hotel guests receive two days of thermal bath access and fitness use included in the room rate. Bathrobe and towel rental adds to the base admission; a combined package with slippers is the most convenient option for first-time visitors. Treatment appointments should be booked ahead of the visit, particularly on weekends when the beauty centre is busiest.
Safety & Etiquette
Safety at Sanadome
Sanadome is generally safe for visitors from age 8 upward, operating as a fully staffed facility with lifeguards in the thermal pool areas. The pools use mineral-rich water from the resort's own springs at a maximum of 37 degrees Celsius, with the main pools at 33 degrees Celsius. Children aged 8 to 18 must be accompanied by an adult at all times. The saltwater pool produces a noticeable buoyancy effect; first-time users should take care near pool edges as the increased buoyancy changes how they move in the water.
Swimwear Rules and Etiquette
Swimwear and shower slippers are mandatory throughout the thermal landscape every day. There are no textile-free days at Sanadome, which distinguishes it from many Dutch wellness facilities and makes it straightforward for visitors unfamiliar with nude sauna culture. Bathrobe use is recommended and can be rented on site. Aqua gym sessions are free for all thermal bath visitors and run at set daily times. Medical conditions including cardiovascular conditions, pregnancy, and musculoskeletal conditions warrant a consultation with a medical professional before using warm thermal pools or steam facilities. Valuables should be stored in a locker. Online reservation is required and walk-in entry is not guaranteed during busy periods. The European Ecolabel reflects sustainable practices in energy, water, and waste management. Advance booking of beauty treatments is recommended, especially on weekends when the 21-treatment-room beauty centre is at its busiest.
