Billions of small bubbles (10-50 microns) that float and reach the entire body surface
The MicroBubble Walk In Bathtub is designed to enhance the bathing experience. The MicroBubble jets infuse the water with up to 50% more dissolved oxygen than regular water alone. These bubbles help to exfoliate the skin and increase muscle relaxation. The tiny oxygen rich bubbles clear out all of the dirt and wast products in your skin. Additionally, the MicroBubble bath will increase in temperature of the bath. This means the bather won’t have to worry about the bath cooling down and can spend more time bathing at ease.

Keeping the Body Warm
MicroBubble Therapy is a great way to keep your bath the perfect temperature. The longer you run the MicroBubble system the warmer it gets. This is because MicroBubbles raise the temperature in the bath by about 1°F every hour. The tiny micro-sized bubbles are the result of this. Since they are so small and pressurized they contain lots of energy. So when they pop they release that energy in the form of small amounts of heat.

Sterilizing Effects
MicroBubble Therapy reduces the need for soap in a bath. These small, oxygen rich bubbles go a long way in sterilizing your bath. Studies have shown that running a MicroBubble Bath for 10 minutes will kill all the Legionella and Aeruginosa bacteria in it. MicroBubbles will also grab other impurities off of your skin such as dead skin cells and lift it in the water.

Psychological Effects
In a scientific study done by Matsushita Electric Works, Ltd., MicroBubble bathing had demonstrated that it is suitable for psychological and Physiological conditioning before going to bed and is a safe bathing method when compared to normal bathing from the viewpoint of physical load because one remains warm longer based on measurements of skin surface temperature, electroencephalogram(a record of brain activity), electrocardiogram(a record of a person’s heartbeat), and subjective evaluations. MicroBubble bathing has been known to give people the impression that they remain warmer longer after bathing and that they are able to relax more than with normal bathing.  In addition, the mechanism allowing MicroBubble bathing containing oxygen to generate effects on the human body has been studied by examining the inhaled oxygen and oxygen concentration in the water. The study results suggest that compared to conventional bathing, MicroBubble bathing containing oxygen is more effective for refreshing and relaxing for a smooth transition to sleep as well as being soothing to dry skin.

Exfoliates the skin
As stated above MicroBubbles do an excellent job of grabbing all the dirt and grim on the outermost layer of you skin. This helps to exfoliate your skin. Your skin will lose all those extra dead skin cells while you are enjoying your rejuvenating bath.

Moisturizes and softens the skin
Our partner NuWhirl ran lab tests that showed that 100% of test participants had improved hydration and moisture content in the upper layer of skin just after 10 minutes of MicroBubble Therapy. A quick dip into a MicroBubble bath and you will feel the silky smoothness of the water that results in an instant increase in the softness of your skin.

The Ella walk in tubs that offer this feature also offer a unique detachable swivel tray, removable rubber backrest, ability to lower the step in threshold, and a sleek 5 Piece Fast Fill Roman Tub Faucet with a pull out hand shower. These walk in bathtubs also comes standard with a textured slip resistant floor and a safety grab bar.

The Ella Elite, Petite, and Royal models are equipped with two 2″ drains, two overflows, and two stainless steel operated openers, instead of one 1 ½” bathtub drain and a single overflow. Each dial-style drain opener has an ADA compatible extension handle for easier gripping and turning, specifically designed for bathers with weaker hands. Both 2” drains are supplied with custom designed PVC elbow connectors, allowing for easy T connection to the 1 ½” house drain. This unique assembly of two 2” gravity drains and two overflows connected into standard 1 ½” house drain allows for air pocket relief, ensuring fast gravity draining in approximately 80 seconds (with ideal plumbing conditions.)

Ella acrylic walk in baths are constructed of the highest grade cast white acrylic, with an easy to clean gloss finish that is reinforced with fiberglass. The shell is supported by a stainless steel frame and leveling legs for ease and durability during installation. The supporting frame as well as the Toe Kick Access Panel allow for simple above the floor drain installation, convenient access to the underside of the tub, and the ability to lower the threshold for easier step in access. Designer chrome fixtures and user friendly controls put the finishing touch on this relaxing and therapeutic bathing experience.

Dual Drain Technology

Each of our stainless steel glass door walk in bathtubs come with 2 two inch drains. These drains are gravity driven and are larger than a standard one and half inch drain. This allows the walk in bathtub to drain in approximately 80 seconds in ideal plumbing conditions. This is important when drain time is so important. A bather can’t exit the bath until it’s completely drained so having dual drain technology is great feature to have.

Stainless Steel Removable Door
Stainless Steel Removable Door

Our main Ella brand of walk in bathtubs all come with a removable stainless steel door with tempered glass. The stainless steel adds a modern aesthetic to the walk in bathtub; you won’t be able to find such an eye catching walk in tub anywhere else. Along with added aesthetic, the removable door allows easier access to clean hard to reach places. So the door is not only stylish but also functional.

Patented 360° Swivel Tray

Some of our inward swing walk in bathtubs come with a patented swivel tray. This tray has the capabilities to swivel a complete 360° so it can be easily moved out of the way when you don’t need it or moved closer when you do. Now the bather can bring along their favorite book or a nice beverage to further improve their bath experience. The 360° swivel tray is only available on certain walk in tubs and you won’t find it anywhere else.

It comes in a sleek chrome finish that adds a nice aesthetic to your walk in bathtub. The included thermostatic control valve is an anti-scald feature that prevents the water from shifting to unsafe temperatures.

Another faucet option you can choose is the Huntington Brass Roman Fast Fill Faucet. The Huntington Brass Faucet comes with a designer spout, a pul out hand shower mixer, a spout and hand shower diverter, and a hot and cold diverter. The faucet has an 18gpm average fill time which is important when it comes to walk in bathtubs as the bather needs to wait for the walk in tub to fill whilst inside. The Huntington Brass Faucet is a great alternative to the Ella Original Brand Faucet Set.

Heated Seat

Another optional feature we offer is the heated seat. Our advanced radiant heaters provide soothing comfort directly to the surface of the walk in bathtub which allow for a heated seat and backrest. With its warm touch, our heated seats deliver the ultimate in comfort, relaxation, and health benefits.
