Aquatic vistas are the crown jewel of many urban high-rise hotels, but none offer an experience quite like the Four Seasons Hotel St. Louis. Inspired by the 19-story hotel itself, the design team
created a dynamic rooftop pool terrace and a day spa environment
focused on hydrotherapy.
Both spaces utilize natural light and color, and feature multiple
bodies of water — all with unique, forward-thinking design
aspects, including a number of green building measures.
On the rooftop pool terrace, the design team combined the elements
of water and fire to create an aquatic space as awe-inspiring as
the majestic cityscape views.
At the center of the deck is a reflecting pool finished in garnet
red, glass mosaic tile, with a raised 4-inch black granite infinity
edge. Positioned to mirror the St. Louis Gateway Arch, the
fountain’s attached whirlpool spa is separated by a glass
partition and flanked by raised water bowl fountains that cascade
into the spa.
Beyond the reflection fountain is the 1,624-square-foot, outdoor,
heated lap pool, which features Italian glass tile and a
grand-stair entrance crafted to accommodate a state-of-the-art
automated pool cover. A 41-square-foot fountain placed in a central
seating area has the same tile work. The fountain features a
360-degree infinity edge base topped with a “fire
Located off to the side is an 850-square-foot deck fountain.
Designed for splashing, the fountain includes a series of spray
jets highlighted at night with color-changing lights

Downstairs on the seventh floor, the aquatic elements in the indoor
day spa are combined with a neutral color scheme and
nature-inspired materials to evoke feelings of peace and
The day spa facility includes separate men’s and
women’s areas, each with a whirlpool spa fashioned with
cream-colored tiles, matching pebble finish and a soothing, sheer
Rounding out the day spa is a 112-square-foot, mixed-gender
relaxation pool situated beside glass windows that offer sweeping
city views. An elegant reflection fountain featuring a cascading
water curtain provides an additional focal point. Made of marble
and tile, the fountain provides a continuous sound of falling
water, creating a mellow, tranquil space.
The spa and rooftop aquatic amenities were created with safety and
sustainability in mind. The Terrace deck fountain, reflection pool,
whirlpool and fire fountain all include space-saving FRP surge
tanks, which create a closed system that reduces heating and
chemical expenses. The day spa amenities are equipped with on-site
chlorine generation. The technology is salt-based, so there’s
no need for a specially outfitted chemical storage space and no
risk in transporting a supply through public spaces.
Other green, cost-saving measures include LED lights and
variable-frequency drives on the pumps, pool cover and splash
All told, the liquid escapes at the Four Seasons Hotel St. Louis
have helped make the property a premier urban resort
