Seoid Spa at Dunboyne Castle Hotel

Seoid means ‘gem’ in the Irish language, which is exactly what Seoid Spa at Dunboyne Castle is. Carefully designed to be an oasis of calm, it provides our guests a further retreat into relaxation. Treatments can be booked as part of your stay with us, or as an indulgent day out.

Guests can avail of specialist treatments, a hydrotherapy pool, heated pool loungers, sauna, steam room, fully equipped gym and outdoor hot tub.  Each facility is reflective of our 4 star status, with a contemporary theme running throughout.

Begin unwinding in the spa’s Thermal Suite.

Start in the hydrotherapy pool, and let the heated water wash away your stress. Once you’re finished with your dip, choose to lounge in our laconium for a dry heat treatment, or our steam room to relax your muscles. Both of these gently raise your temperature, helping your body eliminate toxins. Once you’re done, take a cold shower for extra rejuvenation, and move on to our treatment rooms.

Due to the limited capacity of Seoid Spa Thermal Suites, we cannot guarantee access or availability to use the facilities during weekends (Saturdays and Sundays) unless you have spa treatments booked.  Advance booking is essential. To enquire regarding availability please contact Seoid Team on 01 6816534 or


At Seoid Spa we promote a serene and calm environment where people can escape from their busy schedules. In order to ensure that we fulfil this promise, we need to limit access to the Spa facilities to guests with treatments booked at peak times. We apologise for any inconvenience but the experience we offer to our guests is our priority.

Choose your specialised spa treatment

Our spa treatments were specifically chosen to be pure and utter indulgence. Opt for a radiant glow with one of our facial experiences, reduce tension with a full body massage or stimulate your skin with a rejuvenating scrub. Whatever you choose, only the highest quality skincare is used. Each product is carefully chosen with your individual skin type in mind, for the best results possible.

To help you pick your treatment, we offer monthly specials.

Take a dip in the outdoor hot tub

After your treatment, venture outdoors to finish unwinding in the outdoor hot tub. This is located on a secluded terrace, and overlooks the estate’s lawns. Next, recline on our heated loungers, and avail of the seasonal fruit and herbal teas on offer. If you’d like to continue the pampering, we recommend venturing upstairs for a classic afternoon tea.

Hit the gym

If you prefer to work out to unwind, join our exclusive gym. A range of cardiovascular and resistance equipment is available, as well as free weights. Members also receive unlimited access to the Thermal Suite and discounted rates on spa treatments.
