Waters 420 puts bathing science to work in this progressive product assembly. A bar, hand spray, overhead wall spray, ceiling spray, four wall sprays, two temperature controls, and four volume controls merge to redefine shower luxury.
Overhead Wall Spray and Hand Spray
Waters 420 combines matching hand and overhead wall sprays to soak the bather in water-full enchantment. Uniquely calibrated to shower you in comfort, these 5-1/2” diameter heads boast an amazing 284 points of cascading opulence.
Ceiling Spray
Crowning the shower space is a majestic ceiling spray for an indulgent deluge experience. This solid brass fixture achieves its brilliance through its 12” face and 180 points of widespread soaking spray.
Wall Sprays
In addition to harmonizing hand, ceiling and overhead wall fixtures, Waters 420 boasts four indulgent wall sprays for an invigorating wall shower or contrast bathing experience. Solid brass and fully directional, their broad splashing pattern provides the ultimate in full-body saturation. Unlike most, Bathology wall sprays flutter and excite water to create an expansive and gentle pattern that is sure to soothe. The possibilities abound with this system’s dedicated wall spray temperature control. Select warm water flowing from above and cool wall splashes from below to benefit from the dynamic influence of contrast bathing which uniquely transforms the shower bathing sensory experience.
Hand Spray Holder / Grab Bar
Central to this shower theme is the prominent grab bar/hand spray holder. This striking 24” ADA grab bar supports the universally adjustable hand spray to facilitate a myriad of showering possibilities. A slight nudge or lever movement allows for 180° and 20” vertical hand spray adjustment.
Temperature Control
Engineered into every Waters experience is the Bathology 3/4” temperature control valve. This precise and intuitive solid brass valve provides optimal water blending and flow to its complementary system components. Elegant in its functional simplicity, its dial is faced with water temperature readings ranging from 70 to 120 degrees Fahrenheit for absolute bathing comfort. Waters 420 incorporates a secondary temperature control valve serving its four wall sprays for stimulating dual-temperature or contrast bathing experiences.
Volume Control
Waters 420 comes to life with the activation of its three volume control valves, each serving a unique spray experience. The ability for independent water flow from a 3/4” brass volume control valve to hand, wall and overhead wall sprays is essential to every optimal shower bathing environment. Explore your personal bathing preferences and reinvent the shower by creating your ideal water spray volume, temperature, texture, and soothing or invigorating effect.
