Admiralty Arch’s transformation into a luxury hotel now comes with another reason to linger: a spa partnership with British skincare brand OSKIA, bringing treatments created exclusively for this rather extraordinary London address.
Hilton announced on 7 October that OSKIA will become the exclusive spa skincare and treatment partner for Waldorf Astoria London – Admiralty Arch and its residences. The hotel is due to open later in 2026, introducing overnight stays to the Grade I-listed landmark on The Mall, opposite Buckingham Palace in St James’s.
A hydrotherapy pool, couples’ treatment rooms and a private relaxation area are among the planned facilities. For travellers drawn to London’s grand hotels but equally keen on a little restorative downtime, the combination has obvious appeal: a stay rooted in the capital’s history, with space to step away from the sightseeing.
British skincare, made for this London address
OSKIA’s role will extend across both skincare and treatments, with a collection developed specifically for the hotel. Hilton says these treatments will be available nowhere else, making the partnership a distinctive part of a stay at Admiralty Arch.
The collaboration is also OSKIA’s first with a Waldorf Astoria property anywhere in the world. The hotel has positioned the choice within its wider focus on British and UK-based partners, with the skincare brand developing and manufacturing every product at its own facility in Wales.
Guillaume Marly, the hotel’s general manager, explained the decision: “There is a natural synergy between OSKIA and the hotel. Both are unmistakably British, both are rooted in craftsmanship, and both bring a quietly confident approach to luxury, something our guests will feel in every treatment.”
Georgie Cleeve founded OSKIA in 2009. The brand describes its approach as cellular skin nutrition, inspired by her interest in MSM, an organic form of sulphur. Its proprietary MSM Regen Complex combines bio-available nutrients with biotechnology, which OSKIA says is intended to support healthy, nourished skin.
OSKIA’s Welsh facility handles both formulation and manufacture, keeping those stages within the business. For guests who take an interest in the products used during a treatment, that provenance adds another layer to the partnership beyond the exclusivity of the menu itself.
A spa with room to slow down
The Waldorf Astoria Spa is planned as an intimate element of the hotel’s broader wellness provision. Its announced facilities include treatment rooms for individuals and couples, a sauna, steam room, hydrotherapy pool, ice fountain and private relaxation area, complemented by a fitness centre.
Couples’ treatment rooms are a particularly appealing detail for anyone considering Admiralty Arch for an anniversary or a romantic London escape. They bring a shared wellness experience into the possibilities for a stay, alongside the individual treatment rooms for guests who prefer to make their spa time entirely their own.
The hydrotherapy pool, sauna and steam room give the wellness offer a broader scope than treatments alone. The ice fountain adds a cooling element, while the private relaxation area is intended to provide somewhere to rest.
Personalisation will shape the OSKIA treatments, according to the hotel, with care adapted to individual needs.
The person shaping the experience
Caitlin Ryde will oversee the treatment menu as the hotel’s recently appointed spa manager. Her responsibilities will include leading the team, managing daily operations and setting treatment and service standards, alongside the wider journey through the spa.
European Spa reported Ryde’s appointment in August, describing a background in spa operations and luxury hospitality. Her experience includes work at Fairmont St Andrews, involvement in the pre-opening of Taymouth Castle Club Spa and the operational launch of a private spa in a residential setting.
Ryde said of her approach: “I believe exceptional spa experiences begin with truly understanding each guest. My focus will be on creating a culture where our team feels empowered to connect authentically, anticipate individual needs and deliver service that is intuitive, thoughtful and genuinely personal.”
A new chapter for Admiralty Arch
Sir Aston Webb designed Admiralty Arch, which was built between 1906 and 1911. The arch served as a ceremonial gateway on the approach to Buckingham Palace and formed part of the monument to Queen Victoria, giving the future hotel a setting closely connected to London’s royal history.
The building originally combined offices and official residences with a triumphal arch. It was listed in 1970 and is now undergoing restoration and transformation by Reuben Brothers in partnership with Hilton. The project will introduce a luxury hotel to the landmark for the first time in its history.
The spa is intended to sit within that larger transformation. OSKIA founder Georgie Cleeve has spoken about the importance of the building’s history to the partnership, while the hotel describes wellbeing as an integral part of the guest experience. The result is a planned wellness offering woven into the landmark’s new use.
Beyond the treatment rooms
Waldorf Astoria London – Admiralty Arch is planned to have 114 rooms, suites and residences.
Clare Smyth MBE and Daniel Boulud will provide culinary direction, bringing their respective approaches to Coreus and Café Boulud. For readers whose ideal city break revolves around a beautiful hotel and memorable meals, those names are another reason to watch the opening closely. The OSKIA announcement adds wellness to an already substantial food-led proposition.
The hotel will also include event spaces ranging from grand venues to more intimate settings, with a ballroom accommodating up to 500 guests. That makes celebrations another part of Admiralty Arch’s next chapter, alongside stays, dining and the spa. The range is considerable, even as the wellness area is being presented as deliberately intimate.
A spa treatment and dinner could become a lovely pairing for a special-occasion visit. For now, the useful planning detail is the breadth of what has been announced: two named restaurant concepts, a property-exclusive treatment collection and wellness facilities within one historic London address.
When can you stay?
Hilton’s latest announcement places the opening later in 2026. Its June reservations announcement had described an anticipated autumn opening, so the hotel remains a forthcoming arrival as of 8 October.
When reservations launched in June, stays were available to book from 1 March 2027. Hilton said earlier availability would follow as the opening approached. That reservation date is separate from the expected opening: it should not be read as an announcement that the hotel will debut in March.
Travellers planning a stay around the spa should check current dates through Waldorf Astoria’s booking channels or the Hilton Honors app, particularly if they are hoping to visit before March 2027.
